Since the release of iOS16.1.0 and iOS16.1.1, I have received reports from iOS16.1.0 and iOS16.1.1 users about the crash problem. Later, I discovered that this problem occurred not only iOS16.1.0 and later.
This problem does not occur to all users (approximately one in a thousand)
I have tried several methods (such as using different versions of xcode build App), but still not solved...
And all the people around me who use iPhone can’t reproduce this problem, which also makes testing difficult
Here are the crash logs caught by firebase：
