I started having peculiar problems when using XCode.
Whenever I try to write test with swift, XCode shows an internal error and all the code turns white.
This happens even if I remove the #testable annotation from the code.
I tried reinstalling XCode, but this did not help.
The code builds just fine so I don't have a clue where the problem might lie.
I'm unable to properly develop tests this way, my modules are not recognised, I have no error checking or code completion.
Here is a screenshot of how the problem looks:
Would love to get any guidance on this issue...
So I guess for now there is no good solution to this problem.
It seems to be caused by crashes of SourceKit.
Fortunately the problem is not solved (partially) on my end.
I decided to make this answer a compilation of different things to try when experiencing this:
Restart - try restarting both Xcode and the PC
Clean the project (shift-command-K)
Build your code, I noticed that sometimes it occurs when you just have unrelated build errors somewhere in your project - make sure it builds
Delete the DerivedData folder rm -Rf ~/Library/Developer/Xcode/DerivedData/, but you can also delete it from Xcode
Delete the cache rm -Rf ~/Library/Caches/com.apple.dt.Xcode - Currently this seems to help the most
I will edit and add more solutions if I find any

I'm getting this weird warning. I'm not sure what could cause it. A .dia file extension supposedly indicates a core digraph graphics file. I did not add one and the app has almost no ui at all.
Could not read serialized diagnostics file: error("Invalid diagnostics signature")
It appears to be an internal issue, the following steps seem to reliably resolve it for me.
Installing my uninstalled dependencies (ie: CocoaPods).
Cleaning the build folder.
Removing derived data.
Restarting Xcode
If that doesn't work restarting my computer makes this go away. 🤦
Here's the zsh script line I use (after navigating to the project's folder):
Note: Uses rm -rfs!
rm -rf ~/Library/Caches/CocoaPods; rm -rf Pods; rm -rf ~/Library/Developer/Xcode/DerivedData/*; pod install;
For me this issue occurred after I updated my Xcode to iOS15. The reason behind my issue was some of my swift packages were no longer up to date. Updating all my swift packages solved this issue. To do this simply do
File > Packages > Update to Latest Package Versions.
I also experienced this issue. The reason in my case was lack of storage space on my laptop so make sure to check that too.
Solution for M1 and M2 Macbook
I'm on a 2020 M1 Apple MacBook and none of these solutions worked for me.
The folder where I had the project created in was named 'Client Works' with a space in-between even throughout folder structure.
Previously folder structure: /Users/ABC/Documents/Client Works/AwesomeProject
Change folder structure to: /Users/ABC/Documents/Client_Works/AwesomeProject
Apparently that had an adverse effect on running the pod install properly. I renamed the folder to 'Client_Works' and ran pod install and everything started working.
Check the file and make sure all the document is linked to the project -> Target Memembership
If you're using a third party library, it might be where this warning or error originates. In my case, I had the same error, it was from a third party library not updated for Xcode 13. I had to go to the library on Github to check if they had an update for this error, and they had. Then, I updated the library's swift package. In my case I had to use the exact commit id at which they fixed the error.
I'm quite sure I know the issue and it is severe if you don't use version control. It happened to me twice with working on two different projects, when my disk space was around 7GB free with Xcode 13/13.1. I could not fix it manually, only removing all and cloning the repo again made it compilable again, and freeing disk space of course.
With Xcode 12 I had this issue around 4GB free space, but I could recover at least.
If you have pods in your project then make sure you are opening the .xcworkspace and not the .xcodeproj
When I removed a library from my Podfile I suddenly received a TON of these messages. The usual clean + clear derived data + restart trick unfortunately didn't seem to work for me this time.
Took me a while to figure this one out, but what did work was upgrading from Xcode 13 to Xcode 14. Doing so provided much better error messages! Turns out I needed to import Foundation, UIKit, or another framework in some of my files.
I'm getting the following error:
An internal error occured. Editing functionality may be limited
for all my projects I open with xcode. I've tried the solutions that I've read on here, the only thing I haven't done is restart my Mac, as I am working with macincloud. The error is there for all my old projects. How can I fix this when I'm using macincloud?
This happened to me when I had two versions of Xcode running on the same machine.
The Xcode-select value could be pointing to the wrong version. (For example, if you're running Xcode 9, but it's pointing to an Xcode 8 version that's also installed on your machine, you might run into this)
If this is your issue, then try changing the value to the right directory by using something like this:
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
This also, however, happens if files have incorrect permissions or a library/developer file has been manually deleted.
If you have only one version of Xcode installed, try deleting the derived data of the project and force-closing + restarting Xcode, or even reinstalling the IDE. More on deleting derived data here.
Let me know if any of this was helpful!
I recommend shutting down the app and then restarting. If this doesn't work, then it could be that you have to update XCode. You could also use an alternative to MacinCloud, like XCodeClub.com
Hope this helps!
I had this similar issue in my Mac and the issue has been resolved by my self. I had tried all the answers and also some from other links.
At last what I did is, I checked the storyboard that I have been working as, source code. Then removed the last view controller (Scene) that I had created and been working on from that storyboard file. Then cleaned and removed derived data. Restarted Xcode. And then it was looking fyn. I think there were some issues with the constraints on a storyboard that had around 8 scenes, so that Xcode LLVM couldn't load it correctly. Thanks for the response.
I try to develop an UI Unit Test for my Application.
I created a UI Test Target and wanted to launch the example XCTest which is generated with the creation of the Target.
When I try to launch the Test I get the error message:
Could not obtain the Bundle Identifier for
/Path/from/user/toAppRepo/build/Debug-iphonesimulator/My_App.app
I am not sure, why this is happening, as I did not change Andy configuration and several Questions I have seen here do not help with my Problem, e.g. I set the Buildings "Use for command-line builds" option to "Debug" as mentioned in a similar Question. When I set TEST_HOSTit says, that I could not configure a Test with USE_XCTRUNNER and TEST_HOST.
I tried multiple solutions on this now like, cleaning the project adjusting the project file or deleting the app etc., but nothing helped here.
After discussions with my colleague where everything worked very well (same project) I tried to delete my DerivedData of Xcode with following terminal command:
rm -rf ~/Library/Developer/Xcode/DerivedData
After that I tried to launch the test again and everything worked.
Probably there are multiple issues which lead to this error all with a different solution and this was mine. Hope it helps someone which has the same issue.
I encountered a similar problem and the way I fix it is
Delete My_App.app.
Clean project and re-build it.
I am using Xcode 9 and I am trying to do Refactoring on my Swift based file but every time I am getting below error:
Refactoring engine ranges didn't match initial ranges
Why isn't it matching the initial range?
Workaround: Restart Xcode.
This has not been resolved yet as of January 2018 (Xcode 9.2).
Build your project (Command ⌘ + B) and it will fix the error. After doing it, I could rename my file successfully.
I have Xcode's project created using Xcode8 long time ago. For some reason I have to upgrade to Xcode9 (9.4.1 exactly). Then I experienced that error only on that old project, not the new one created using Xcode9.
So i think that error related to project issue. So I decided to compare the settings between old and new one. There are some differences, and after several tries, by changing Optimization Level for Debug solved refactor issue.
In project editor, select your Target, Build Settings
Set Optimization Level (Debug) = No optimization [-Onone]
Delete DerivedData folder related to your project in /Users/YourMacUsername/Library/Developer/Xcode/DerivedData
Clean project shiftcommandk.
Build project commandb.
Update For some reason, it's not happening for me anymore. I noticed also whenever I don't let indexing finishes before trying to start doing a refactor or tap on refactor many times, still see the error, but not permanent anymore.
I asked an engineer at WWDC 2018 about this issue. This issue was happening for me in only one project in my workspace. Other projects in the same workspace works fine. At the moment, there's no solution to this issue. If you want to help Apple to fix this, you can close your Xcode and run following command in terminal:
SOURCEKIT_SERVICE_LOG=3 /Applications/Xcode.app/Contents/MacOS/Xcode 2>&1 | tee /tmp/sk-log.txt
And then try to reproduce the issue and send them the log file (/tmp/sk-log.txt) so they can narrow it down and hopefully fix it in future Xcode versions.
Notice This is project related issue and won't be fixed with OS updates, Xcode updates, or any number of restarting applications, at least the one that I'm having.
I have the same issue in Xcode 10.3.
Refactoring didn't work when I right clicked → refactor → rename on the class name in the class definition. However it did work when I did the same somewhere in code where I use that class.
Product -> Clean Build Folder -> Quit Xcode -> Reopen Project -> Build
I update to Xcode 10 and finally refactoring now it works again after a year without refactoring
I am on Mac M1 and using Xcode Version 12.5 beta 3.
I was facing the same issue when trying to rename ViewController.
Before renaming it, I moved it to a new group, and my code was in a running state. Not sure if that was the reason for the issue.
But I restarted the Xcode and the issue was resolved for me.
I was experiencing the exact same issue. It turned out that I had my build configuration set to Release mode. Changing it to Debug, cleaning build folder and recompiling fixed the issue for me.
Remove DerivedData
This worked for me for this error and other kind of refactoring errors.
Close Xcode
Remove DerivedData:
rm -rf ~/Library/Developer/Xcode/DerivedData
I experienced this on a Mac M1, using Xcode Version 14.1 (14B47b).
This helped:
Clean project: shift-command-k.
Build project: command-b.
I've been working on a project in Xcode 3.2.5 and today I tried migrating it up to Xcode 4.0. It compiles just fine; I can navigate to and execute the .app without a hitch (as expected). The only thing that is screwy is the fact that Xcode cannot launch the application, and displays the following error when it tries:
"Error starting executable. No executable file specified. Use the "file" or "exec-file" command" (image not available)
I've scoured the Project and Xcode settings and have been googling for half the day, but all I can find are dead ends and people bashing other people about breaking Apple NDA. FYI Xcode 4 has been released, and is no longer under NDA.
Should I just start a new project and copy in my source? Sounds wrong to me, but brute force works when brute force works.
Thanks in advance
At a guess, the schemes it set up for you based on your v3 targets and build settings might not be quite right. From the schemes menu, choose to edit the current scheme, then select the Run action from the list and make sure the appropriate exectuable is selected.
I ran into the same issue this question came up so I spent my time identifying the issue, reproducing the issue, narrowing it down and explaining as best I could how to not make it happen - as well as the general frustration that comes with an issue like this (it hit me on 2 different versions of Xcode in 2 weeks).
If you're going to delete my post then at least take the time to try and answer the question as I had tried to do.
Now, on to the reply that actually tells how this issue may be created and how to avoid that.
I JUST had this happen creating an app for iOS. Why? I renamed my target executable.
Just tested this by checking out a new copy of the source and rebuilding.
The app ran fine on my device.
Went in to Xcode 4.2, renamed the target. Ran the app. "Error starting Executable..."
I changed the filename back. Same error.
Cleaned and ran the app again and it launched.
Renamed the app, cleaned and ran it again. Not so much luck.
Don't rename your app by renaming the target.
This is such a stupid limitation. Apple lets you rename your target app, but by doing so, this prevents your app from launching on the device.
EDIT: I haven't checked in any code, but now I can't check out and build and run any app without this happening. How do you get the device/xCode out of this state once you've gotten it in to it?
Even the app now crashes on launch at int retVal = UIApplicationMain(argc, argv, nil, nil);
This is in Xcode 4.2 on Snow Leopard, but I got into the same state with Xcode 3 on another Machine last week.
Edit 2: Rebooted the device, rebooted my Mac. Built and ran in the simulator first, then on the Gen4 iPod touch. It works.
I had this issue when migrating a project from Xcode 4 to 4.1, and it ended up being due to the Target's "Product Name" being different in the debug and release configurations. A holdover from when I changed the name of the product many versions ago. So check that...
I've downgraded Xcode from 4.2 to 4.1 only to encounter an error at build and run on device: "Error starting executable. Don't know how to run ...". I've cleaned the project (Xcode > Project > Clean) and cleaned the build folder (Xcode > Project > (hold option key) Clean Build Folder). After that I had to build again and it built okay on iPod touch 4g running iOS 5.
Well, it sure sounds like a whole family of bugs behind that error message!
I got the error after loading up an Xcode 3 project under 4.2.x for the first time.
None of the above tips worked for me, however what I eventually did was switching from GDB to LLDB.
That fixed it.
It looked like the new path to the executable wasn't properly recognized by GDB (i.e. once locally at PROJECT/build/Debug/... in Xcode3 but now in the usual temp. folder location with Xcode 4 it was still looking for the executable in the build folder relative to the project sources)
I duplicated the target and rename the copied on to different name, I got this error message. What I did is to clean the project, exit Xcode, restart the Xcode, then it can run on my device.
