App doesn't run on simulators or archive, devices work

Question

App doesn't run on IOS simulators or building archive but runs on devices. It used to run fine, suddenly (can't pinpoint what is currently different that could cause this) a similar issue happened on android with the File name is too long error after multiple flutter cleans, removing all caches it worked on a real device then on the simulators again, doesn't work for IOS though.

Error message

/Users/yassin/Library/Developer/Xcode/DerivedData/Runner-dnjtfjbcotehrpgzrmybaaeugzpl/Build/Intermediates.noindex/ArchiveIntermediates/Runner/InstallationBuildProductsLocation/Applications/Runner.app: File name too long Command CodeSign failed with a nonzero exit code

Unhandled error domain NSPOSIXErrorDomain, code 63

More details on the error when running from xcode for a simulator:

Failure Reason: Unhandled error domain NSPOSIXErrorDomain, code 63 User Info: { FunctionName = IXCopyItemAtURL; IDERunOperationFailingWorker = IDELaunchiPhoneSimulatorLauncher; SourceFileLine = 121; }

One weird behaviour i've noticed is that dart analysis is taking so long to launch, and when running on a device it builds in normal time but takes so long to install (4+ minutes) On a Macbook M1, on both android and ios which is something unusual.

Things i have tried:

1. Flutter clean + Flutter pub get
2. Deleting xcodes derived data folder + Restarting laptop and xcode
3. flutter pub cache repair
4. Pod install, update
5. Revoking all certificates, installing new ones
6. Closing automatic signing, downloading profile
7. Locking & unlocking Keychain login access.

Solution

What worked for me after many days was deleting all hidden files in the project folder besides git related ones, .idea, .packages etc.. As well as podspec.lock and the Build folder manually.

What worked for someone else with the same issue was "Removing the flutter installation folder, then fetching again from the repo"

Both options should hopefully solve your issue.
