After submitting my app for review, I received a rejection on account of it crashing in MacOS 12.4 environment. The Objective-C app was developed in MacOS 12.4 and the app runs OK in Xcode and as a standalone executable. The crash log shows the exception type as SIGABRT and documentation. indicates that the crash may arise from an uncaught exception. Part of the crash log is shown below. How can I find out where the problem is occurring in my code?
