Hi all!


My app has been running perfectly until I upgraded to Xcode 9 and I keep getting this error message:

The direct cause of the crash you’re seeing is this:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil'

Some code is attempting to add 

nil
into an 
NSMutableArray
. That’s not supported, and attempting this causes 
NSMutableArray
to throw a language exception.

The line after that shows the backtrace of the code that’s going this. It’s hard to garner much from a raw backtrace like this. However, if you grab the associated crash report and symbolicate that, it’ll give you a bunch of context for the issue.

For more information about getting and symbolicating crash reports, see Technote 2151 Understanding and Analyzing iOS Application Crash Reports.

Finally, this log line is worrying:

[reports] Main Thread Checker: UI API called on a background thread: -[UIApplication statusBarOrientation]

Someone in process is calling UIKit from a secondary thread. In this case the associated backtrace has symbols, so you should investigate from there.

In addition to everything Quinn told you, your storyboard doesn't have the entry point view controller set, so it's not loading in the view controller from the storyboard. You'll need to fix that from interface builder by designating the "starting" view controller of your storyboard.

Thanks Quinn and Owen for your help and effort, I managed to fix it in the end, turns out I had a quiz level answer that contained 13 characters when the quiz only supports a maximum of 12 characters for any answer. I removed the offending answer and it worked like normal.


Once again your help and thoughts were much appreciated! 🙂
