iOS Exception Backtrace - App entry not symbolicating - ios

Question

I have received the below exception backtrace from Apple for an app I had submitted to the app store. I have symbolicated the log but my app's entry has not symbolicated. Any idea what I can do to achieve that? Please see Entry # 14 below which provides more detail. Any help would be much appreciated

Answer 1

Finally solved the problem. I was invoking UIAlertController in my code to present an action sheet with various options. To cater to devices that don't have a camera, I had added a conditional statement to directly present an ImagePicker instead of an action sheet.
iPAD testing was carried out only on the simulator which doesn't have a camera, thus directly invoking the ImagePicker. When he Conditional statement was removed, it tried presenting the Action Sheet through a PopoverPresentationController and crashed - as is evident in statement 2 of the Exception Backtrace.
I subsequently added the following code to fix the oversight:
if let popOver = optionMenu.popoverPresentationController {
popOver.sourceRect = sender.bounds
popOver.sourceView = sender
}
