`No such module 'Promises'` when building for testing on Xcode 15.0-beta5 #11656

pgorrindo · 2023-08-07T14:56:49Z

Description

We have been using the Firebase iOS SDK for some time in our iOS project. In looking to start using Xcode 15 exclusively, when using current versions of everything (specified below), we see the following issue, using the same Xcode project file:

In Xcode 14.3.1, Build for Running -> builds ok
In Xcode 14.3.1, Build for Testing -> builds ok
In Xcode 15.0-beta5, Build for Running -> builds ok
In Xcode 15.0-beta5, Build for Testing -> fails to build with the following error:

No such module 'Promises in FirebaseSessions at line 21: @_implementationOnly import Promises

We've tried adding the -ld64 other linker flag, cleaning the build and Derived Data folders, as well as removing and re-adding the Firebase package.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

paulb777 · 2023-08-07T15:25:07Z

@pgorrindo Thanks for the report. Would you check if File -> Packages -> Reset Package Caches makes a difference?

pgorrindo · 2023-08-07T15:34:41Z

thanks @paulb777 -- tried reseting package caches, same result as originally described.

paulb777 · 2023-08-07T15:46:21Z

Hmm, we may need a reproducible example, since I'm able to successfully build Sessions for testing in beta 5.

pgorrindo · 2023-08-07T20:33:11Z

Here is a reproducible example @paulb777 -- https://github.com/whforward/promises-debugging -- a fresh new Xcode project created with Xcode 15-beta5, bringing in only the current 10.13.0 version of the Firebase SDK, and I get the results as described above.

Greatly appreciate any insight you might have here.

paulb777 · 2023-08-07T20:52:56Z

Thanks! I've reproduced and I'm investigating ....

paulb777 · 2023-08-07T21:44:03Z

I've reduced the test case to determine it's sufficient to have only FirebasePerformance and FirebaseCrashlytics as dependencies of the test target. Removing one of them is sufficient to build successfully.

We might want to do a bit more investigation, but my current thought is that this is an Xcode build system bug.

A workaround may be to remove one of those two dependencies if you don't need to depend on both in the test target.

pgorrindo · 2023-08-07T22:57:43Z

Thanks @paulb777 -- ok, this is what I've found:

recapitulate FirebaseCrashlytics + FirebasePerformance

If I whittle down to just those two, I can reproduce what you see -- Promises error if both Crashlytics and Performance are present:

and then by removing Performance, it builds:

removing FirebasePerformance alone is insufficient

but if I add everything back, and only remove FirebasePerformance, then I get a new error, about undefined symbols in FirebaseFirestoreSwift:

ultimately need to remove all Firestore, and FirebasePerformance

to get past the undefined symbols error, I needed to remove all three Firestore dependencies, and FirebasePerformance, to get be able to successfully Build for Running and Build for Testing:

Thoughts?

You are correct, Paul, that we don't need all of those dependencies for the test target. But we do need Firestore, unfortunately. Thoughts?

paulb777 · 2023-08-07T23:21:52Z

Yes, I can reproduce with only FirebaseFirestoreSwift as a dependency of the test target:

Seems to be some sort of C++ symbol or linkage problem. I'm not sure why it only shows up in the test target. @ncooke3 any ideas?

Beta 6 makes no difference on the Firestore grpc linkage problem.

Hi @pgorrindo, I unfortunately don't have any advice to work around this issue at this time. We'll keep this open to verify against the issue against future betas.

bummer, ok thanks for the update @ncooke3

Beta 6 makes no difference on the Firestore grpc linkage problem.

Same with Xcode 15 Betas 7 and 8, and Firebase v10.14.0 -- the problem persists.

Same with Xcode 15 Release Candidate, and Firebase v10.15.0 -- the problem persists in the minimal reproducible example previously noted. Trying -ld64 or -ld_classic as other linker flags doesn't fix the issue either. Any other thoughts @ncooke3 or @paulb777 ? CC @andrewsexcellent

Yep. I still see the C++ linkage issue from Firestore with the Xcode 15 RC. The original issue reported here of not being able to add both Crashlytics and Performance to the test target has been addressed.

I suspect something about the Xcode 14 generated binary for Firestore may be missing something needed by Xcode 15. We'll continue to investigate.

Hi @pgorrindo, we identified a fix for the undefined symbols errors. The fix should go out in the next release.

Until then, I have a manual workaround that can help unblock your workflow.

Find the Process FirebaseFirestore.xcframework step in a build log from your project. This should appear whenever building a target that depends on Firestore.

Copy the path of the xcframework being processed. In my case, it's the following path from the above image:

/Users/nickcooke/Library/Developer/Xcode/DerivedData/testApp1-gplcekzwfpjbfyendznnuavepyqs/SourcePackages/artifacts/firebase-ios-sdk/FirebaseFirestore/FirebaseFirestore.xcframework

The FirebaseFirestore.xcframework contains a directory for each supported architecture slice. Within each slice is a FirebaseFirestore.framework. For each of the architectures you build for, find the module.modulemap within the architecture's corresponding FirebaseFirestore.framework.

For me, the module.modulemap used when building your repro project is here:

 /Users/nickcooke/Library/Developer/Xcode/DerivedData/testApp1-gplcekzwfpjbfyendznnuavepyqs/SourcePackages/artifacts/firebase-ios-sdk/FirebaseFirestore/FirebaseFirestore.xcframework/ios-arm64_x86_64-simulator/FirebaseFirestore.framework/Modules/module.modulemap

Then, open the module.modulemap in a text , vim, etc. and it should look like:

framework module FirebaseFirestore {
umbrella header "FirebaseFirestore-umbrella.h"
export *
module * { export * }
  link framework "Foundation"
  link framework "Security"
  link framework "SystemConfiguration"
  link framework "UIKit"
  link "c++"
  link "z"
}

Link in BoringSSL-GRPC, gRPC-Core, and gRPC-C++ so it looks like this:

framework module FirebaseFirestore {
umbrella header "FirebaseFirestore-umbrella.h"
export *
module * { export * }
  link framework "BoringSSL-GRPC"
  link framework "gRPC-Core"
  link framework "gRPC-C++"
  link framework "Foundation"
  link framework "Security"
  link framework "SystemConfiguration"
  link framework "UIKit"
  link "c++"
  link "z"
}

Repeat this last step for each of the architectures you wish to build for.
Try building your target again, and it should work with the locally modified artifact.

You will need to repeat these steps if the DerivedData directory is deleted, or if you re-add Firebase via SPM.

Let me know if you have any trouble.

recapitulate FirebaseCrashlytics + FirebasePerformance

removing FirebasePerformance alone is insufficient

ultimately need to remove all Firestore, and FirebasePerformance

Thoughts?
