Firebase-ios-sdk: Framework not found FirebaseInstanceID

[skuske]

Step 0: Are you in the right place?

Yes.

[REQUIRED] Step 1: Describe your environment

• Xcode version: 11.5 (11E608c)
• Firebase SDK version: 6.26
• Firebase Component: Firebase/Analytics, Crashlytics, RemoteConfig
• Installation method: CocoaPods

[REQUIRED] Step 2: Describe the problem

XCode gives me the following error during build:

Framework not found FirebaseInstanceID

Steps to reproduce:

The issue occurred with one of the latest updates, and I found that I am not the only one with this issue:

https://www.hackingwithswift.com/forums/swift/firestore-pod-failing-after-update/101

And according to the above URL one way to fix this is by adding

pod 'Firebase/Messaging'

to my POD file, although I do not use messaging.

Why am I getting the error, although my integration is fully compliant with the docs?

My podfile.lock:

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

This may be related to the Installations migration. What likely happened is the pod update removed InstanceID in favor of Installations, but you still have a stale -framework FirebaseInstanceID linker flag somewhere in your project. If you find the flag and remove it, the error should go away.

Many thanks. That did the trick! :o)
