Xamarin Studio can't see XIBs in shared project for macOS - macos

I'm using an approach described here for my app.
Currently, I was able to setup such structure for Android and iOS platforms. In general, I have the global core (.NET lib), platform specific core (platform specific Class Library), and some extension (platform specific Class Library).
The problem appears when I try to configure in same way structure for macOS platform. I was able to create platform specific class Library with components that should be reused in apps (for now this is just 1 class with the xib file). But, when I want to use this package in macOS target I got runtime error specific to macOS platform:
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[NSNib _initWithNibNamed:bundle:options: ] could not load the nibName: MainView in bundle (null).'
That's strange, because I set up in same way structure for iOS app, and within the iOS target, it's work just great: all source files, xib files, resources are visible and could be freely used from the package.
Note:
I found few issues like described above and some solutions that could resolve this blocking point:
rename xib file - doesn't work
put xib file in rootDir - doesn't work
make sure that BuildAction for file is "InterfaceDefinition" - doesn't work (it always set to InterfaceDefinition)
recreate files - doesn't work
clean all, remove file, reboot, create new - doesn't work
put files in resource dir - doesn't work
force include into package - doesn't work
check that class in VB is correct - doesn't work (was always correct)
check Xcode folder with autogenerated files - doesn't work (in general all files was always there, few times autogenerated h and m files were missed -> I receive another error, but when manually create them -> I faced again with such error)
manually specify bundle for resource - doesn't work (this is strange because for iOS lib all resources are available within the null (main) bundle) - I try to explicitly specify bundle - doesn't work.
So, how to prepare class library within some source files, xib, other resources, so it can be freely accessed from any project that uses this package? Or maybe some steps described above was incorrect?

According to Chris Hamonds from Xamarin Forum here is the answer:
I believe this is a bug we've fixed but is not in the latest builds in our channel. I can reproduce with our Alpha build but installing a build from: https://jenkins.mono-project.com/view/Xamarin.MaciOS/job/xamarin-macios-builds-master/

Linker error building Adobe DNG SDK on MacOS 11

I am working on a project that uses Adobe's DNG SDK 1.6 library, and it is supposed to work on Windows and MacOS.
The library has instructions on how to build it for both platforms, but I had to figure out an error that came up on Windows with Visual Studio. I am not very experienced with big C++ projects so it was not trivial but I got it working. Most of my own code will be done in C# .Net Core, calling the native libraries using a wrapper class with P/Invoke.
Now for Mac that's a different story, I have a MacOS 11 VM, installed Xcode 12.5.1 and followed the steps provided, as expected, it does not work. Bare in mind this is my first time touching Xcode and MacOS.
The project I am trying to build is dng_validate, and it depends on two libraries built by these projects: XMPFiles64 and XMPCore64.
The library projects build without any hiccups, each one of them creating a ".a" file in the folder: dng_sdk_1_6/xmp/toolkit/public/libraries/macintosh/intel_64_libcpp/Debug, they are named libXMPFilesStaticDebug.a and libXMPCoreStaticDebug.a respectively.
When I try to build the dng_validate project, I get the following error:
Library not found for -lXMPFilesStaticDebug
Because of the the error starting with an "l" instead of "lib", under both libraries project settings, I changed the "Executable Prefix" setting to "l" instead of "lib". Rebuilt both of them and made sure the file names changed as expected. But the error persists when trying to build the main project.
Under dng_validate's project settings, there is a setting called "Library Search Paths" and it does point to the proper aforementioned folder using a relative path. I even changed it to an absolute path to see if that would make it work.
I am really lost here, does anyone have an idea of what might be causing it?
Well... After asking on other forums and almost hiring a freelancer to fix this for me, I tried another shot in the dark of renaming the library files and it worked.
I changed the extensions of libXMPFilesStaticDebug.a and libXMPCoreStaticDebug.a from ".a" to ".dylib" and it just compiled and blew my mind with it.

Xcode create shared framework across lots of targets

I'm making stuff for IOS, Mac, and WatchOS - I have certain common functionality that is more about me and the way I program than about whatever it is I'm programming - helper methods etc
What I'd like is to have a "Common" framework or library in my app which is included into every other library. I understand I need a separate target for each of ios, macos, watchos, but I can't figure out how to set it up.
I can create a framework - and it comes with a target - I can duplicate that target and change stuff, but I don't seem to be able to change it from IOS to macos for instance. I can create a separate macos target, but then I can't seem to be able to change where it gets the code from.
Essentially in my source tree I want a single directory:
Common
and then have target frameworks CommonIOS, CommonMacOs, CommonWatchOS - that all just compile "Common". How do I achieve that?
You're misusing the word "framework". All you want is to keep some source code as a library that all your projects and targets, no matter what system they'll be compiled for, can use. You are describing a Swift package.

Xamarin Android binding duplicate packages causing "Program type already present" build error

I am trying to build Xamarin Android binding libraries for two different RFID hand held scanner SDKs (from two different companies), and then reference them in a Xamarin.Android project. So the end goal is to have one application that can run on Device A or Device B and depending on the device manufacturer it will use a different implementation of a "scanner" interface. If I try to reference both of the resulting dlls from the Xamarin.Android project, then I get the following error:
Program type already present: com.hsm.barcode.DecodeOptions
Looking in the jars using JD-GUI as suggested in the Microsoft Docs I can see the problem is that both of the jars have a com.hsm.barcode package:
What is the best way to workaround this issue?
Note that if I use only one of the dlls then I have no issues.
What I have tried:
Using a single Xamarin Android binding library project for both jars - this gave exactly the same result
Renaming all of the classes in the jar to eliminate duplicate class names like this: <attr path="/api/package[#name='com.hsm.barcode']/class[#name='DecodeOptions']" name="name">DecodeOptions2</attr>. When I do this, in reflector I can see that the class name has indeed changed, but I still get the build error when building the Xamarin.Android project
Renaming the namespace in one of the projects: <attr path="/api/package[#name='com.hsm.barcode']" name="name">com.hsm.barcode2</attr>. Again, I can see the updated namespace in reflector but still I get the same "Program type already present" error when building the Xamarin.Android project
Similarly I have tried removing both the namespace and the duplicate classes using remove-node but seen similar results
This leads me to believe that this isn't necessarily an issue with the binding process but rather a more Android related problem. I have found some similar Android questions where people mention that you can use exclude module in gradle to remove dependencies [1] [2], but a) there seems to be no concrete answer that this is the right approach in this case and b) as I have been able to find gradle is not a tool that is used as part of the Xamarin/Visual Studio process.
My final desperate attempt to get something working was to unzip one of the jar files, remove all the .class files that are causing issues, then rezip and use this in the Android binding library and then reference this dll in my Xamarin.Android project. This seems to work (the project builds and runs) but I'm not sure it is the correct/safest/most stable solution.
To summarize, the question is: if you have two jars with duplicated namespaces/packages and you want to use both of these Jars in a Xamarin.Android project how can you avoid the resulting Program type already present: com.hsm.barcode.DecodeOptions error message.

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.

Do I have to do something to get OCunit tests to compile out of box with XCode 4?

I just installed XCode 4 today (using Apple mac app store), and I created a new Mac OS application, and tried to switch to test mode,and build the test skeleton code it generated for me. It failed here:
In mytests.h:
#import <SenTestingKit/SenTestingKit.h>
The error is:
file://..mytests.h: error: Lexical or Preprocessor Issue: 'SenTestingKit/SenTestingKit.h' file not found
Now, when I use locate from the terminal to find SenTestingKit.h, I notice it exists under the /Developer-old/Library/Frameworks folder (which is what XCode 4 installer renamed my /Developer folder to). There is no new /Developer/Library/Frameworks. And I can't seem to find SenTestingKit.framework on my disk, other than the developer-old one.
What's up? It seems SenTestingKit.framework is not shipped with XCode 4.
Update:
Furthermore, When I copy my old SenTestingKit framework from XCode 3 into /Developer/Library/Frameworks, it sort of builds, but it doesn't work the way I would expect. The dummy test is designed to just fail, but when I "run test", I just get the normal cocoa app document window opening, and no indication that my test has failed (as I intend it to do).
This is pretty bad. I can't get a Unit test to FAIL. That's not the usual situation for me, you understand.
You may find that the reason for this is because you've installed Xcode 4 into a directory such as /Xcode 4.x/ or similar. The space is causing the problem because the -I paths are "Xcode" and "4.x/Library/Frameworks".
To fix this, what you need to do is select your test target, and under its build settings go and find the Framework Search Path, and put quotes around the two arguments, so you have:
"$(SDKROOT)/Developer/Library/Frameworks" and "$(DEVELOPER_LIBRARY_DIR)/Frameworks"
Then you default tests will compile, link and fail.
You will maybe need to import the framework into your project. Otherwise, the header file won't be recognize.
If you can't see the framework you're looking for, you can adjust the framework look paths in your project's build settings.
When you're building unit tests in the same project as you main code, make sure that XCode 4 didn't automatically connect you mytests.m file into the "Compile Sources" section of your main code.
For example, if you have two targets in our project:
MyProject
MyProjectTests
Check the Build Phases for MyProject to see if XCode added mytests.m into the "Compile Sources" accordion. This will cause your builds to fail because SenTest isn't included in the main project.
