+[_CFXNotificationTokenRegistration keyCallbacks] (CoreFoundation)

I have received this report through firebase analytics and I have no idea what it is. Would you help me?

I tried to reproduce but to no avail.


Fatal Exception: NSInternalInconsistencyException

Trying to complete an interactive gesture but the animation coordinator is nil! (gesture=<_UIBarPanGestureRecognizer: 0x100cb82e0; state = Ended; view = <UILayoutContainerView 0x100c25000>; target= <(action=_gestureRecognizedInteractiveHide:, target=<UINavigationController 0x10100f400>)>> action=Hide)

hello,


I'm having the same issue but I still cannot find out why. My guess is that the callback from a background task is called twice but I am not sure about that. Or Maybe Firebase swizzling method for registering the push notification token causes the error.

I got the same crash, and the majority happened on iOS 12 and 13!

0  CoreFoundation  … __exceptionPreprocess
1  libobjc.A.dylib … objc_exception_throw
2  CoreFoundation  … +[_CFXNotificationTokenRegistration keyCallbacks]
3  Foundation      … -[NSAssertionHandler handleFailureInMethod:object:file:lineNumber:description:]
4  UIKitCore       … -[UINavigationController _gestureRecognizedInteractiveHide:]

There’s two things in play here:

  • Why did 

    -[UINavigationController _gestureRecognizedInteractiveHide:]
    (frame 4) trip over an assertion? (A)

  • Why is 

    +[_CFXNotificationTokenRegistration keyCallbacks]
    in the backtrace at frame 2? (B)

With regards B, I suspect that this is a result of symbolication failure. It’s very unlikely that 

-[NSAssertionHandler handleFailureInMethod:object:file:lineNumber:description:]
would end up in 
+[_CFXNotificationTokenRegistration keyCallbacks]
and then end back in 
objc_exception_throw
. Good symbolication is hard, so issues like this are not uncommon in third-party crash reporters.

With regards A, I believe the answer to that lies in the exception description:

Fatal Exception: NSInternalInconsistencyException
Trying to complete an interactive gesture but the animation coordinator is nil! (gesture=<_UIBarPanGestureRecognizer: 0x100cb82e0; state = Ended; view = <UILayoutContainerView 0x100c25000>; target= <(action=_gestureRecognizedInteractiveHide:, target=<UINavigationController 0x10100f400>)>> action=Hide)

If you need more help with that, I recommend that you post over in App Frameworks > Cocoa Touch because that’s more likely to connect you up with UIKit experts.

Same issue i am facing.

This is a pretty generic crash signature, so it’s possible that you’re looking at a completely different issue. Does your crash report include the text Trying to complete an interactive gesture but the animation coordinator is nil? If so, that’s likely to be the same issue and I’m happy to continue discussing it here.

If not, it’s probably some other issue. In that case I recommend that you start a new thread for your issue. Please tag it with Debugging, so that I see it, and add a complete Apple crash report, per the instructions in Posting a Crash Report.
