What happened?

This bug has been around for some time now. Using Firebase as an external package with tuist creates a huge number of warnings in Xcode.

e.g. using:

.package(url: "https://github.com/firebase/firebase-ios-sdk", from: "10.28.0")

with: .external(name: "FirebaseAnalytics") .external(name: "FirebaseCrashlytics")

How do we reproduce it?

Min reproducible example project: https://github.com/kekearif/DemoFirebase

1.) tuist install 2.) tuist cache 3.) tuist generate

Run app and look at warnings.

Finally can remove the .package from Package.swift and remove .external(name: "FirebaseAnalytics") and .external(name: "FirebaseCrashlytics") from Project+Extension.

1.) tuist clean 2.) tuist generate

Observe that the warnings are now gone.

Had a very similar issue though I wasn’t using Firebase.

I was able to fix it by setting the debug format to DWARF (instead of DWARF with dSYMs).

In my config I removed DEBUG_INFORMATION_FORMAT[config=Debug]=dwarf-with-dsym
