firebase-ios-sdk: Xcode 13 - iOS 15 error message appears in Xcode console

[REQUIRED] Step 1: Describe your environment

  • Xcode version: 13
  • Firebase SDK version: 8.7.0
  • Installation method: CocoaPods
  • Firebase Component: Don´t know

[REQUIRED] Step 2: Describe the problem

Steps to reproduce:

When I bring my App in the foreground or background following error message appears in the Xcode console. Prior iOS 15 this error message wasn’t shown. So I don’t know if this can be ignored or it will cause a crash on the release version.

I am also having the same problem. This issue occurs when testing on an actual device. (I am using iPhone 12 Pro, iOS 15.0.1)

The app works fine, but I’m worried that the Appstore will process it as a crash.

Please fix this. Doesn’t crash but it makes debugging hard to follow because it spams it quite often.

As discussed above, this is an Apple issue so best to follow up on Apple forums about resolution timing. See https://github.com/firebase/firebase-ios-sdk/issues/8744#issuecomment-948866894.

I’m going to lock the issue for additional comments here.
