需要iOS崩溃日志帮助

Question

I've been receiving a few crash logs for a bug that I haven't been able to replicate. The crash occurs right when the user taps on a textView in the app. The textView is located under a tableView and I extend the bottom constraint of the textView to fit the keyboard on screen. The constraint extends through keyboard notifications (NSNotificationCenter keyboardWillShow).

Below are two crash logs. Any help would be appreciated!

Exception Type:  EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000

Answer 1

Users were reporting crash on "textfield". They were actually referring to a cell that sorta looks like a textField. The cell was being miscast. Careless mistake - will need to make UI clearer.
