Running with Address Sanitizer and Zombie Objects as shown above does not show any Additional information in sumulator logs.


Most important question is: How do I determine which object is causing the problem and/or what that problem might be?


Xcode Version 11.3.1 (11C504)

I tried to post a device crash report which has more information but the forum software tells me it has an invalid character, but not which character or were it is located?
