Why does exact copy of Xcode Build Configuration fail? - xcode

I have a react-native app with bridged Swift code that is building, running, and archiving without issue with Xcode 10.0 with the default Release and Debug build configurations. I use Xcode -> Product -> Archive or the "Play" button and everything works as expected. Great!
Then today I added a new build configuration that is an exact duplicate of Release. It is named Release copy. I did the same for Debug as well, and its duplicate is Debug copy.
If I try to run the same Archive or Run tasks using the copies, the tasks fail at Precompile bridging header.
/Users/whaley/dev/app/theApp/theApp-Bridging-Header.h:5:9: error: 'React/RCTBridgeModule.h' file not found
#import <React/RCTBridgeModule.h>
^
1 error generated.
<unknown>:0: error: failed to emit precompiled header '/Users/whaley/Library/Developer/Xcode/DerivedData/theApp-ckvpglaqydwzhadbbyqoprcjvnod/Build/Intermediates.noindex/ArchiveIntermediates/theApp/PrecompiledHeaders/theApp-Bridging-Header-swift_320079J7441HX-clang_QK5YQQC41WXA.pch' for bridging header '/Users/whaley/dev/theApp/ios/theApp-Bridging-Header.h'
Odd, in my opinion, since this should be an exact copy of a build configuration that was working fine.
If I switch back to the original Build Configurations everything is fine. The originals consistently work and the copies consistently fail.
I tried disabling the Precompile bridging header task, but just encountered a different, and similar error. Again, the original build configs worked where the copies failed.
I'm already using Find implicit dependencies, the bridging header is named properly, I'm not using Cocoapods, I've rebooted and cleared Xcode's Derived Data, and please bear in mind that it does work fine normally. It's only these duplicate build configurations that fail.
Why might this be happening? Am I missing a step here? Is this perhaps a limitation of react-native and it only supports the default build configs?

Naturally, the moment I posted my question I managed to find the answer I needed via Google
Thanks to Mateusz Klimczak for clearly illustrating the problem and resolution on their website.
Add an entry to Headers Search Paths for each new Release build configuration:
$(BUILD_DIR)/Release-$(PLATFORM_NAME)/include
Add an entry to Library Search Paths for each new Release build configuration:
$(BUILD_DIR)/Release$(EFFECTIVE_PLATFORM_NAME)
One might wonder why this is needed when we only change build configuration name and it was already working for Release. React Native supports Debug and Release build configurations out of the box, while any other configuration needs to be set up manually.
Sure enough, that fixed it. The answer is that only Release and Debug are supported out of the box, so that additional config is required for non-standard Build Configurations.

failed to emit precompiled header

Good Afternoon
I am trying to implement googles heatmaps into my map based project.
In this particular project, I get the following errors when trying to build.
failed to emit precompiled header '/Users/zachwilcox/Library/Developer/Xcode/DerivedData/OddJobs-gbnkfettubuccoheinzfovrqefub/Build/Intermediates.noindex/PrecompiledHeaders/OddJobs-Bridging-Header-swift_3WGH9SNI96Z2-clang_16JN3VASQHE4C.pch' for bridging header '/Users/zachwilcox/Desktop/OddJobs/OddJobs-Bridging-Header.h'
and a follow up that says
'Google-Maps-iOS-Utils/GMUHeatmapTileLayer.h' file not found
I'm not sure why this is happening because I created an entirely new project and did the same implementation and it worked perfectly. But when I run it on my existing project I get these two errors.
I have been researching this problem for a while now and I can't figure out what the problem is. I have the Bridging header set to the .h file.
I have tried most steps that individuals have tried to give with their answers but for some reason, it's not working for my project. Thank you in advance. When reading googles installation guide, it said that all I needed to add was one bridging header file which is the code you see in the image below. When researching it, I have seen that I needed to add a .m file as well however I still get the same error when I do. again, in my dummy project, I don't have the .m file just everything you see below and everything compiles.
There are chances you have 'Find Implicit Dependencies" turned off for the selected Scheme. If you have updated/installed pods and try to build the project, it will more likely fail if this option is unchecked for the selected Scheme.
From Apple's Document:
Parallelize Build – This option allows Xcode to speed up total build time by building targets that do not depend on each other at the same time. This is a time-saver on projects with many smaller dependencies that can easily be run in parallel.
Find Implicit Dependencies – This is a very powerful option that allows Xcode to resolve what targets need to be built for the primary target of the scheme to be built successfully. However, this does come with some sharp edges that you have to be aware of.
Situation: You link a library against your application target and create an implicit dependency to that library’s target.
Scenario 1: “Find Implicit Dependencies” is enabled.
Result: The library will get built prior to building the application target. The application target will then link against the library and build successfully.
Scenario 2: “Find Implicit Dependencies” is disabled.
Result: The library will not get built prior to building the application target. The application target fail to build.
Fix: To ensure that the second scenario does not happen, you must add the necessary targets into the targets list and order them correctly.
If your project includes pod then you've to set the pod configuration for the test project too..
Select Root Project in File inspector -> Project Name -> Info -> Configurations
Set configuration for your test project same like your main project

Swift: App Installation Failed Could Not Inspect The Application Package (When Using Frameworks with XCode 6)

I'm having difficulties running a compiled app on an iPhone 6 (iOS8). It works fine in the simulator.
I get this error message:
App installation failed
Could not inspect the application package
Originally there were error messages - such as the one here but I fixed this temporarily by moving the output into the correct location. However even though all of the libraries are being codesign'ed correctly and are now found I am unable to use the app on my device.
There seems to be no further error messages and therefore no way of debugging anything. How exactly do normal iOS developers debug problems which give no error messages?
I guess the underlying problem is that my project is getting quite complex, there are a lot of moving pieces: a few cocoapods, Alamofire, ReactiveCocoa, and Moya.
I have a few general questions:
Where can I find information that documents the use of frameworks in XCode 6?
What is the difference between "Build Phases -> Link Binary With Libraries", "Build Phases -> Copy Files", "General -> Embedded Binaries" and "General -> Linked Frameworks and Libraries"?
Everything is compiling completely fine for the simulator, including the cocoapods, but I note that there are libPod.a files and wonder whether they need to be compiled into the app?
Mostly I am hoping to find some way of finding out why the application package can't be inspected. Surely whatever software that inspects this must be able to be debugged?!!
Edit:
For the record, (1) there is no file called Resources in the root folder as I get nothing back when I do this "find . -name Resources" so it cannot be that issue, (2) I have run "Product -> Clean" and then tried to build again and this does not solve the problem either, (3) the Info.plist does contain a CFBundleName which is set to "${PRODUCT_NAME}" currently (which I believe is set elsewhere.)
I managed to fix this. I am not sure exactly what the solution was, but effectively what I did was to remove all of the cocoapods, detach all of the extra projects that were being used to compile frameworks, and then completely clean the build folder (by holding Alt while going to Product > Clean.)
I then added each of the frameworks back and made sure that each of them would compile.
I checked the build output and near the bottom of each I was able to find the location in which the frameworks were being built.
I then went back to the parent app, and was able to change the framework search paths to include the folders that the frameworks were being built in.
I may have changed a couple of other paths, too, though I cannot remember completely.
I think that basically the issue was a combination of (1) a very dirty build path, (2) leftover files and bad configuration causing issues, (3) frameworks being built in the wrong location.
check your "Copy Bundle Resources",delete info.plist if it contained.
It's work for me in Xcode 6.4

OS X Framework Library not loaded: 'Image not found'

I am trying to create a basic OS X Framework, right now I just have a test framework created: TestMacFramework.framework and I'm trying to import it into a brand new OS X Application project.
I have built the .framework file and imported it into the new project, The framework appears to link okay, and I can reference the public header file I added to the framework build phases section.
However, when I try to run the container Application I get the following Error:
dyld: Library not loaded: /Library/Frameworks/TestMacFramework.framework/Versions/A/TestMacFramework
Referenced from: /Users/samharman/Library/Developer/Xcode/DerivedData/TestMacContainer-dzabuelobzfknafuhmgooqhqrgzl/Build/Products/Debug/TestMacContainer.app/Contents/MacOS/TestMacContainer
Reason: image not found
After a bit of googling I realised I needed to add a Copy Files section to my container application build phases, so I have done this and set it up like so...
However, I am still getting the runtime error. I'm obviously doing something wrong here, but the Apple developer library resource for this references Xcode 2, so isn't very helpful!
What have I missed?
UPDATE:
I can see in the build log that my TestMacFramework.framework is being copied into the .app contents/frameworks directory, but it isn't being installed to the Library/Frameworks directory on the HD
UPDATE 2:
The build links correctly if I manually copy the TestMacFramework.framework into the Library/Frameworks directory
[Xcode 11+]
The only thing to do is to add the framework to the General->Frameworks, Libraries And Embedded Content section in the General tab of your app target.
Make sure you select the 'Embed & Sign' option.
[Xcode v6 -> Xcode v10]
The only thing to do is to add the framework to the Embedded binaries section in the General tab of your app target.
So I managed to get it working, it's quite simple when you have the right instructions. What I was looking for was a 'private' framework which lives in the App bundle rather than being written to the system library folder.
Building The Framework
Add a target to create a Cocoa Framework
Within that targets 'Build Settings' configure the 'Installation Directory' to '#executable_path/../Frameworks'
Build library, and access the .framework from the archive or products directory
Including The Framework
Drag the created .framework file into the Xcode Project, be sure to tick 'Copy Files to Directory'
In the containing applications target, add a new 'Copy File Build Phase'
Set the 'Destination' to 'Frameworks'
Drag in the created .framework
It was quite simple for me, i just added my framework to my embedded binaries under app targets
The options above where not possible for me to include.
I solved it by specifying the Runpath Search Path
This is on the 'Build Settings' tab.
In the 'Linking' section.
Change 'Runpath Search Paths' into $(inherited) #executable_path/Frameworks
I ran into the same issue but the accepted solution did not work for me. Instead the solution was to modify the framework's install name.
The error in the original post is:
dyld: Library not loaded: /Library/Frameworks/TestMacFramework.framework/Versions/A/TestMacFramework
Referenced from: /Users/samharman/Library/Developer/Xcode/DerivedData/TestMacContainer-dzabuelobzfknafuhmgooqhqrgzl/Build/Products/Debug/TestMacContainer.app/Contents/MacOS/TestMacContainer
Reason: image not found
Note the first path after Library not loaded. The framework is being loaded from an absolute path. This path comes from the framework's install name (sometimes called rpath), which can be examined using:
otool -D MyFramework.framework/MyFramework
When a framework is embedded into an app this path should be relative and of this form: #rpath/MyFramework.framework/MyFramework. If your framework's install name is an absolute path it may not be loaded at runtime and an error similar to the one above will be produced.
The solution is to modify the install name:
install_name_tool -id "#rpath/MyFramework.framework/MyFramework" MyFramework.framework/MyFramework
With this change I no longer get the error
Deleting derived data saved it for me
None of these issues solved this for me. The problem in the end was pretty easy. It looks like its a pretty major Xcode bug which I have logged the problem and fix under Apple bug: 29820370. If you are struggling (as it seems like there are several pages of problems similar to this ) then it would be great if you can raise a bug on bug reporter: https://bugreport.apple.com/ and reference the bug I raised to gain visibility. I want to make Xcode back into the pleasure that it was before - and this is something I am sure Xcode should have fixed itself.
Here is the fix:
1. Open Keychain - go to Apple Worldwide Developer Cert.
2. Double Click on it
3. Change the permission level from "always trust" to use System Defaults
4. Save and close it
5. Restart Xcode, Clean and build your project and it should be gone.
Screenshot below of the correct settings:
Hope this helps!
When you drag a custom framework into a project under Xcode 10.1, it assumes that the framework is a system framework and puts the framework into "Link Binary With Libraries" section of "Build Phases" under your target.
System frameworks are already on the device so it is not copied over to the device and thus cannot execute at runtime so KABOOM (crash in __abort_with_payload, and disinforming error: "Reason: image not found"). This is because the framework code is not copied to the device...
In reality, to have Xcode both link the custom framework and ensure that it is copied along with your code to the iOS device (real or simulator) the custom framework needs to be moved to "Copy Bundle Resources". This ultimately packages the framework along with your code executable to be available on the device together.
To add a custom framework to a project and avoid the Apple crash:
Drag custom framework into your iOS project file list
Click ProjectName in Navigator -> TargetName -> "Build Phases" ->
Link Binary With Libraries disclosure triangle
Drag custom framework out and down to "Copy Bundle Resources" section below (Xcode now moves the framework reference, fixed in Xcode 10)
Run in simulator or device
The custom framework thus gets copied along with your code to your target device and is available at runtime.
[editorial: you would think Xcode would be smart enough to figure out the difference between one of it's system frameworks which need not be copied to the device and a custom framework that is, oh I don't know, in the project root directory hierarchy... 🙄]
Xcode 11 :
in Xcode 11 add framework into General->Frameworks, Libraries And Embedded Content
after adding make sure you select Embed & Sign option
There should be a 'Run Script' into 'Build Phases' with this: '/usr/local/bin/carthage copy-frameworks'
On the 'Input Files' of that 'Run Script', you should add the path to your libraries. Like this:
If you accidentally reset your keychain, this can occur due to missing Apple certificates in the keychain. I followed this to solve my problem.
I had the same issue and was able to fix by re-downloading the WWDR (Apple Worldwide Developer Relations Certification Authority).
Download from here: http://developer.apple.com/certificationauthority/AppleWWDRCA.cer
If you are using Xcode 11, ensure that you have the framework added in Frameworks, Libraries, and Embed Content under Target settings - General. Change Embed status from - 'Do not Embed' to 'Embed & Sign'
What solved it for me was changing abstract_target to target for the main target in my Podfile. I had previously set it to abstract_target and this caused the described error. Now it works like a charm
I faced this issue with Xcode 13 betas with the UniformTypeIdentifiers.framework. The app failed to run on iOS versions lower than 13.
The below approach fixed the issue :
Go to the target -> Build Phases -> Link Binary With Libraries -> Add the framework -> Add the status as "Optional"
The above worked perfectly for me! Hope this helps!
For Xcode 8, some stale products will be removed from derived data folder refer to this solution.
Apple: In macOS 10.12 and later, Xcode cleans up stale derived data, precompiled headers, and module caches. (23282174)
The Xcode build system supports stale file removal of some types of build artifacts that were produced in a previous build, but have since been removed from the project.
Base on the author's thought, I found this build log from my case.
Remove stale build products
/bin/rm -rf /Users/usename/Library/Developer/Xcode/DerivedData/myapp-esvvhwwwwngijeemhatmklwzoxnb/Build/Products/Debug-iphonesimulator/myapp.app/Frameworks/AliyunVodPlayerSDK.framework
/bin/rmdir /Users/usename/Library/Developer/Xcode/DerivedData/myapp-esvvhwwwwngijeemhatmklwzoxnb/Build/Products/Debug-iphonesimulator/myapp.app/Frameworks
After creating a new copy file phase and copy the target stale framework to Frameworks destination, the above removal log disappears after rebuilding.
Just clarify my situation and reason, hope it's helpful for someone.
For me this was the solution, after many hours of searching!!
For some reason, well into the development of a Swift 2.3 custom Framework, Xcode 8 had removed the DYLIB_INSTALL_NAME_BASE setting from the project.pbxproj file. A little walk into the Build Settings / Dynamic Library Install Name Base setting back to #rpath fixed it.
(from https://forums.developer.apple.com/thread/4687)
I found that this issue was related only to the code signing and certificates not the code itself. To verify this, create the basic single view app and try to run it without any changes to your device. If you see the same error type this shows your code is fine. Like me you will find that your certificates are invalid. Download all again and fix any expired ones. Then when you get the basic app to not report the error try your app again after exiting Xcode and perhaps restarting your mac for good measure. That finally put this nightmare to an end. Most likely this has nothing to do with your code especially if you get Build Successful message when you try to run it. FYI
Got the issue when trying Xcode 9 beta and going back to Xcode 8. A simple Clean on the target resolved the issue.
I had the same issue for a different reason.
I've created a new configuration to Debug and Release (under PROJECT -> Info tab -> Configuration).
And I had to change my pod frameworks shell script (Pods-"appName"-frameworks.sh , under Targets Support Files) to make it work.
[Xcode 9]
The only thing that worked for me:
Target > Build Phases > [CP] Embed Pods Frameworks
Uncheck "Show environment variables in build log" and "Run script only when installing"
I tried many fixes, but what worked for me was to delete a missing target listed in the build tab of the build scheme. You can get to it by opening the edit window of the current scheme.
Edit: My UI testing target was not working as well, and the solution I found was to delete it and generate it again.
open xcode -> general -> Embedded Binaries -> add QBImagepicker.framework and RSKImageCropper -> clean project
just add QBImagePicker.framework and RSKImageCropper.framework at embedded binaries worked for me
I think there is no fixed way to solve this problem since it might be caused by different reason. I also had this problem last week, I don't know when and exactly what cause this problem, only when I run it on simulator with Xcode or try to install it onto the phone, then it reports such kind of error, But when I run it with react-native run-ios with terminal, there is no problem.
I checked all the ways posted on the internet, like renew certificate, change settings in Xcode (all of ways mentions above), actually all of settings in Xcode were already set as it requested before, none of ways works for me. Until this morning when I delete the pods and reinstall, the error finally gonna after a week. If you are also using cocoapod and then error was just show up without any specific reason, maybe you can try my way.
Check my cocoapods version.
Update it if there is new version available.
Go to your project folder, delete your Podfile.lock , Pods file, project xcworkspace.
Run pod install
I experienced that problem only when running on real device (iPhone SE). On simulator project worked as expected.
I did try all fixes from this very thread and from here.
None of those worked for me.
For me problem was solved after restarting iPhone (sic!).
I did:
clean build folder,
clean derived data,
delete app from device,
reboot device
And it finally works. :)
If every other solution fails don't forget to try it out.
Xcode 11 :
Build Phases -> Embed Frameworks
This might happen with Pod Frameworks.
I was facing the same issue with AnswerBotProvidersSDK.framework and my mistake was, I set Run Script checked for Install builds only in targets build phases.
Incorrect settings:
Correct Settings:
For me for some reason xCode (12.5 up to this moment) decided that my Notification Service Extension Target should not have correct paths to frameworks. I suspect that this is happened after I've updated from xCode 12.1 to 12.5.
So I was getting the same error related to one of my internal frameworks. To fix this problem do the following:
go to Project's General Tab
Select your target (in my case it was Notification Service Extension Target)
Make sure that Framework and Libraries section contains your missing framework. I've left it Embed Without Signing in my NSE Target, but it is also was added with Embed & Sign to my primary app target
Keep your target selected and switch to Build Settings tab
There in a search bar enter LD_RUNPATH_SEARCH_PATHS (make sure that All possible settings will be displayed and not just Basic)
You will see Runpath Search Paths and it was empty for me.
Add 3 following values there:
$(inherited)
#executable_path/Frameworks
#executable_path/../../Frameworks
This is what helped me.

Swift build fails: target might include it's own product

Has anyone run into this issue? I was experimenting with porting an existing obj-c app to Swift, and after quite a few successful builds the project will no longer build and immediately gives the error: Unable to run command 'CompileSwift normal' - this target might include its own product. Along with many other 'target might include it's own product errors'.
What I've Tried:
Checking Target Dependencies: There is nothing listed as a target dependency in Build Phases.
I've tried completely deleting the product folders, and have went through all the files multiple times but with no luck.
If I simply replace the Swift files with the old obj-c files it builds fine, no errors at all.
Restoring to a snapshot prior to any Swift modifications results in building as normal, but even if I add a brand new Swift boilerplate file and bridging header, then click build, it fails with the same errors.
I had the same issue. I couldn't work out exactly what was causing it, but realised the same code would build find on a different Xcode 6 install on a different machine.
I solved it by deleting my cached builds, etc, in ~/Library/Developer/Xcode, while Xcode is not running. "Clean" alone from within Xcode didn't do it.
You should find that when you re-launch Xcode your app will build fine.
Deleting my app target from "Build Phases -> Copy Bundle Resources" worked for me. (Somehow it was being included for bundling?)
I could reproduce the problem. In the objc-to-swift bridge header I imported a header of an objc class, which also imports swift-to-objc header. There was a cycle of imports and this could be the reason Xcode complaint.
I think for now it is best to avoid such cyclic importing between swift and objc. You might want to check that out.

Xcode shows many errors but program compiles and runs fine (in both simulator and device)

After installing the CocoaLumberjack' log compressor class I've been getting this annoying behavior: Xcode complains that there are many undeclared identifiers and gives me many errors (not warnings but errors with the red icon).
The thing is that I can compile and run my iPad app just fine but Xcode won't do any autocompletion. I tried cleaning the build folder (Product > option + Clean), and also deleting derived data. I've also rebooted to no avail.
As you can imagine this is a pain to work with. I did have this behavior happen before on a previous version of Xcode; it had something to do with stuff in my precompiled headers file but using the solution above would always fix it. I'm currently using Xcode 4.4 (4F250).
Sample error I'm getting:
Semantic Error: use of undeclared identifier 'DDTTYLogger'
The above happens even with classes that I wrote myself and that have not changed since installing the CocoaLumberjack compressor class.
I finally solved this after MANY attempts using the following:
Remove the last #import from my Prefix.pch and build again. Errors would happen (obviously). Put the line back and build again. No errors would show and after 10 seconds or so, errors would come back again.
Repeat the above except instead of the last #import, remove the last TWO imports, then three, four, etc. I did this until I removed five imports and when I put them back and waited, Xcode stopped complaining.
Note that this didn't occur to me at all. I read this solution on a blog somewhere.
Weird bug...
Open build settings and set "Precompile Prefix Header" to "No", that solved my problem.
Kudos for: https://stackoverflow.com/a/7035492/936957
I've been running into these issues constantly on all the latest versions of Xcode, in both Objective-C and Swift.
I noticed today that I was getting the errors in one particular class file. I removed it from some extra targets it was in and the errors finally went away!
I think Xcode has some fundamental bugs with it's handling of multiple targets right now. My theory is that if the other target is not built, you will essentially see errors from that target. Anyway hope this helps someone.
Not bad,
If you follow these Steps-
1-Clean Xcode(Cmd+Shif+K).
2- Clear Derived Data(Cmd+Shift+G).
Enter this path( ~/Library/Developer/Xcode/DerivedData/).
3- Quit and open again Xcode.
This problem can cause by setting "Target Membership" for some files are not the same.
Example:
A class XYZ put in file "a.swift" and it's used in file "b.swift". But "Target Membership" setting of "a.swift" is not the same "Target Membership" setting of b.swift.
Check "Target Membership" setting as below:
I was having issues with a library installed via cocoapods. Going to Build Settings and searching for 'Allow Non-modular Includes In Framework Modules' then setting it to Yes did the trick.
I had it on Xcode 10.1 when I accidentally pressed:
Cmd+Shift+U - ( build for Testing )
try Clean (Cmd+Shift+K) and then:
Cmd+Shift+R ( build for Running )
After update to Xcode 11, I met the same problem. I tried all the mentioned advices (cleaning folders, turning on/off different settings, restarting xCode), but nothing helped. Also, I have a big project in C, so, I'd like to keep using precompiled headers.
Finally I found that simple restart of Mac OS solves the problem! It's really weird behaviour, but I'm happy anyway that I found a solution – it's hard to code when lots of colourful error messages float around.
For me it helped cleanning the project. XCode->Product->Clean
I got the similar type of issue.
Alternate option to fix this is
Open organizer and delete the derived data of your project or delete all the projects in organizer projects tab. It works fine..
I just had the same thing in Xcode 5.1.
I fixed it by making sure there were no blank lines between #import's
I have removed some extra spaces and extra lines from .pch file and it xcode stopped complaining
This happened to me as well, but cleaning didn't fix it. What did was quitting and reopening XCode. Afterwards, all the phantom errors were gone. For those wondering, the tabs you have open when you close will still be open when you reopen.
I had this issue recently. It can be remedied in some cases by deleting the ModuleCache folder inside DerivedData, along with the project folder in DerivedData. Note that Xcode must be quit before doing this.
Running on Xcode Version 10.1 (10B61), I set the build setting "Increase Sharing of Precompiled Headers" to NO. I was working in an .xcworkspace with many projects sharing the same frameworks, and no Objective-C bridging header (meaning I've added no obj-c code myself). I'm not sure when Xcode did away with .pch files by default, but I didn't have any of those in my project.
Open up a terminal and create a nice little function accessible via the command line...
nano ~/.bashrc
add (making the necessary substitutions between the pointy braces)
cycle() {
git stash save "BACKUP"
git checkout <<SOME OTHER BRANCH>>
git branch -D $1
xcodebuild -allowProvisioningUpdates -workspace <<YOUR WORKSPACE>>.xcworkspace -scheme <<YOUR SCHEME>> -configuration Release clean
git checkout $1
}
^X and save it by following the prompts, then enter source ~/.bashrc to make it visible to the current terminal session.
Make sure your branch is pushed to origin, cause we're going to delete it :)
Call the function using cycle <<MY BRANCH>> (once it's run you might want to call git stash pop to restore any working copy changes)
Hope it works for you! Xcode, get on your game!
In my case (mixed objc/swift project) at least part of errors were caused by absence of imports for some used frameworks, e.g. "import UIKit". Project was compiled successfully because frameworks were anyway included in headers in Prefix.pch file. But errors were shown, for example about not finding method defined in UILabel extension, and yes, this extension was without "import UIKit". So I think these errors in most cases depends on Prefix.pch precompilation/updating.
Touching Prefix.pch, cleaning, removing derived data, closing/opening XCode sometimes helps, but not always.
Using SPM, it can be that the Module you import, which you use at the location of the errors, has missing dependencies itself.
In my case I had an error about a missing initializer, XCode trying to use a different one than the one already defined in the other Module. But the project compiled fine! Nothing worked at first. Then I tried first cleaning, and then Product -> Perform Action -> Compile "myfile.swift" and it showed what the missing dependency in the dependency was! Note: This goes recursive. In multiple places a depenendency may have not been declared in the package.swift -> compile the same file repeatedly until it compiles successfully.
So.. it wasn't that the module with the error had a missing dependency, but rather that the direct dependency did miss a Module-dependency declaration in its package.swift declaration.
My explanation is that to generate the Error-output of XCode, Modules get compiled alone on their own. Import errors then show up. But when Modules are built as part of a larger Module, then that large module may import the missing dependency of the broken sub-Module already, making the build pass.
