Under "Build Settings" – "Architectures" check that you don’t have "arm64" excluded under "Excluded architectures" for release, as all new iOS devices use this architecture.
Check the Executable File in the Info(.plist). It should be named the same as your Product in Products
I fixed it by adding x86_64 to VALID_ARCHS. Build Setting search "VALID_ARCHS",check the x86_64 is there or not, add and run.It worked with me .
Check if you have any other info.plist-s added to project.
I had similar issue when I added some pod sources (MKStoreKit) to the project – it had several info plists for different platforms which interfered with original one. Deleting wrong info plists solved the issue.
I have to delete the ‘DerivedData’ folder:
Check if all files are available.
Targets -> Build Phases -> Compile Sources
If you see faint files, then they need to be removed or added.
I have this issue on a react native application and I can resolve it reinstalling cocoaPods.
Inside the ios folder on your react native project.
EDIT: I’ve found a solution…
The problem in my case was because of project configurations and Pods. In the long life of my project the configuration files for the schemes changed and Xcode, using the new build system, did not like.
To fix it, just go to the Project -> Info tab. Under Configurations change the Based on Configuration value of the Targets and set them to None. Please note that I’ve changed only the Targets.
Now close Xcode and launch pod install from the Terminal.
reopen Xcode and launch your project.
Old answer:
I may have found a workaround to this issue… not a solution but a workaround.
I have to work on a not really recent project that was built using the Legacy System that, as you may know, is deprecated now.
While I was using Xcode 12 everything was fine. Then I installed the Xcode 13 GM and I upgrated the project to the new building system and I started to experience this issue. I have the same problem with any Xcode 13.x version. With the betas I had not, as far as I can remember.
The strange thing is that "sometimes" (I could not reproduce it sorry), the new build system worked… but just for a while.
The building phase succeeds but then, then the app is installed on simulator OR on a real device, I have that annoying message that we know…
This morning I may have find a solution…
In Xcode go to File -> Workspace Settings, keep the Legacy Build System and check the box "Do not show a diagnostic issue about build system deprecation"
Now the app builds and can be installed.
Honestly I don’t know it is an Xcode bug or not… maybe it is.
resolve it using
pod install.as Frank said, I also use RN in my app.
I have tried clean derived data & even reboot, still happening
I’m also get the same error. Let me share how I fix it.
I write cpp code on vscode.
I deleted a .cpp/.h file that I didn’t need anymore a few days ago.
Everything nice and happy when I working on vscode.
".app is not a valid path" appeared when i switched back to the xcode to verification function.
I was confused.
(I don’t immediately remember my delete operation a few days ago)
The key isn’t the dialog showed "Executable Not Found",
Switch to "Issue Navigator" and drag to the bottom…
Now the ERROR shows up in front of U:
Finally the solution is :
TARGETS -> Select your ‘Target’ -> Build Phases -> Compile Sources :
Select the ".cpp" file that had been delete, then "Remove Items" by click the second "-" button in the lower left corner.
Please make sure that your runner isn’t missing AppDelegate.swift or Runner-Bridging-Header.h file.
In my case, my AppDelegate.swift file and Runner-Bridging-Header.h files were deleted, so I copy and paste both the files in ios>Runner folder again from some other project (usually both of these files are same in all projects, just need to add the code lines for firebase configurations).
if you are using git, there’s huge chance there might be conflict in .pbxproj due to multiple people adding stuffs together. During the resolution xcode might try to recover those ‘lost references’ it got confused and unable to resolve the once there references. find those ‘recovered references’ in project explorer and remove them if they are invalid
Had the same issue. I deleted the simulators and added them again.
I also had the same issue. These steps worked for me. I’ve done the following steps in XCode.
Executable again.
