I'm getting daily, frequent crashes with the following trace. This happens on the main thread when the application is launching in the foreground or in the background during a background fetch. The line it crashes on is simply:
UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];
trace:
Fatal Exception: NSInternalInconsistencyException

I cannot reproduce this however. I'm seeing these reported in Crashlytics and similar complaints on Stackoverflow are unanswered. I'm not sure what the app is doing wrong. Seemingly the app has already been launched and is active.
Even a @try @catch around this does not help. I tried shipping the latest update with @try @catch around this line, but the assertion still manages to throw an exception.
Any ideas? It happens mostly on iOS 11 and have been reported for 11.2.6 as well.
