Crash when dismissing UIActionSheet

Question

I am facing a mysterious crash issue when running our app (64 bit complaint) inside another app. The crash happens within UIKit after UIActionSheet is dismissed.

Below is the sequence of actions I am performing:

1. Tap on the action sheet button on right side of navigation bar.
2. Tap on some action makes a server call.
3. Tap on the action sheet button again and then tap on Edit button to bring the table in edit mode.
4. Table comes in Edit mode but application crashes.

Console Logs:

Answer 1

It was a mysteriously weird issue. I just put a strong property for my UIAlerView which I was showing on tap on my first action sheet and put that in the header file and it worked. Putting the property in the extension was crashing it.
