iOS 15 VectorKit Crash

Could you show the code that crashes ?

The crash is happening deep in mapkit > victorkit and iOS 15, its the same code running since years and the crash never appeared. so i would like to trace but where to start since i don't have a specific line that i could start from. any suggestions ?

Could it be because I'm initializing MKMapView in viewDidLoad ?

Same here, In the Firebase console I received these crashes only on iOS 15.x . Did you get these crashes also after building the app with Xcode 13+?

Building with Xcode 13+ did not help, Crash returned. Did you manage to solve this problem somehow?

We are also seeing this, only iOS15 devices are causing this

These crashes appearing i guess after building with Xcode 13. we are talking about 61 crash from 600k users in 30 days its a lot.

i already reported the crash on feedbackassistent but still there is still not updates about it. Adding second queue of the crash:

The issue is still on iOS 15.2... please report it in feedbackassistent Apple Maps SDK.

Yes still seeing this on a decent number of 15.2 devices too

So far I have not seen any 15.4 crashes for this

Same crash report found on iOS 15.3.1
