I've got a crash at App Launch in iOS 13 Beta Device. I can't able to launch my App [Release] in iOS 13 beta but it is working fine in iOS 12. I'm not getting an Exception pointer as well. Please help me understand this crash.

Will be get fixed in the next iOS 13 beta release? or Do we need to fix something in the App side? if yes, your suggestions are welcome.

Crash Info:

Fatal Exception: CALayerInvalidGeometry

CALayer position contains NaN: [207 nan].

I'm seeing the exact same thing. Only happening on iOS 13.

We have the same error occured.

We discovered that we had some Nav Controller Nav Bar's Shadow set to an alloc but not initialised UIImage, eg just [UIImage alloc].

This code was being fired as part of the initial view construction on app launch.

Whenever we had UIImages defined this way, the app would crash.

The fix was to also init the image, [[UIImage alloc] init]

Hope this helps.

I had same exception ... CALayer position contains NaN: [207 nan] when setting a frame value to the base view controller's view, where the frame value is definitely not Nan.

****** Setting Optimization Level to None somehow fixed this error. ******

Can anyone explain this?

I'm using Xcode 11.2.1
