When set metalLayer.presentsWithTransaction = true, and when I call nextDrawable.present() in bg thread (our rendering thread is not main thread), the app sometimes will crash with:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Modifications to the layout engine must not be performed from a background thread after it has been accessed from the main thread.'
Expected: App will not crash....The rendering should be ok.
Stack trace:
Fatal Exception: NSInternalInconsistencyException
Modifications to the layout engine must not be performed from a background thread after it has been accessed from the main thread.

Thanks in advance
What version of crashlytics are you running? If you are running iOS 13 you should upgrade to 3.14.0. as it will give you better detailed information about the crash.
I have an app developed in Flutter, I track its crashes by Firebase Crashlytics.
According to it in 99% of the time it is crash free, but during 1% of the sessions on IOS I have a strange crash at startup of the app.

Do you have similar experiences? Is there any way to fix it?
Thanks a lot!
I do my own error handling by catching any exceptions and logging them manually. I use NSSetUncaughtExceptionHandler(&myExceptionHandler); and log the stack trace using [NSException callStackSymbols]. Up until recently my logs contained the symbolicated stack trace. Now they don't and there weren't any code changes related to the logging. This is occurring on all devices and versions of iOS. I am able to manually symbolicate my logs but it is quite cumbersome. Any insight would be greatly appreciated.
Previously my logs looked like:

Looks like Apple now performs a kind of repackaging and eventually stripping debug info.
I did a manually install of the Firebase SDK to my iOS project. Following the instruction from README.md
I included all the files from the Analytics folder:
FirebaseAnalytics.framework
FirebaseInstanceID.framework
GoogleInterchangeUtilities.framework
GoogleSymbolUtilities.framework
GoogleUtilities.framework
And I included "import FirebaseAnalytics" to my AppDelegate. and then I called:
FIRApp.configure()
But Xcode is still telling me this:
*** Terminating app due to uncaught exception 'com.firebase.core', reason: '[FIRApp configure] Firebase Analytics is not available.'

What am I doing wrong here? FYI. I am running Xcode Version 7.3.1 and I have the latest SDK.
Did you add the -ObjC flag in "Other Linking Flags" setting? When I did this in my Objective-C project, the app stopped crashing when trying to load Firebase. I also included all the Firebase files, used the Firebase.h header and [FIRApp configure] to call Firebase.
I am running Xcode 8.
