Unable to add -ObjC in other linker flags #12960

Closed AjIthiOS18 closed 5 months ago

AjIthiOS18 commented 5 months ago

Description

I first installed the Google Tag Manager via SwiftPM, added the -ObjC in the other linker flags everything was working fine. But when I installed Firebase and FirebaseUI, I started to get duplicate symbols error. Once I removed the -ObjC from other linker flags, the error also disappeared but I need to include the -ObjC for both Firebase Analytics as well as GTM to function.

Reproducing the issue

Step 1: Install GTM via SwiftPM Step 2: Add the -ObjC in other linker flags Step 3: Install Firebase and FirebaseUI via SwiftPM Step 4: Build the project

Xcode Version

15.2

Installation Method

Swift Package Manager

Firebase Product(s)

Analytics, Crashlytics, Firestore, Messaging

Targeted Platforms

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

Hi @AjIthiOS18, I tried to reproduce the issue by installing both the Firebase SDK and GTM, and I'm able to build my app successfully. But when I tried adding the FirebaseUI, the duplicate symbol error appeared. I also tried removing the Firebase SDK but the issue persists. With this, it seems like there's a conflict between the GTM SDK and FirebaseUI. You may try to reach out to GTM support or FirebaseUI repo.

@ncooke3 Is investigating on the FirebaseUI side - https://github.com/firebase/FirebaseUI-iOS/pull/1188

AjIthiOS18 commented 5 months ago

Thank you @rizafran and @paulb777

paulb777 commented 5 months ago

The fix is merged for the next FirebaseUI release

morganchen12 commented 5 months ago

This should be fixed in FirebaseUI 13.2.0.
