iOS Crash Logs functions

Hi

I’m following the this tutorial to try and debug my app on my local device. I can’t seem to work out where the problem is. I have sync’d my device and am viewing it through XCode, so I expected to see the functions within “MyApp” that have caused the problem. But only some functions are listed. The rest are raw HEX I believe

Exception Type:  EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000001, 0x000000010046c448
Termination Signal: Trace/BPT trap: 5

I looked on StackOverflow and found this answer to what the reason itself is: ios - My app is rejected with Exception EXC_BREAKPOINT (SIGTRAP) - Stack Overflow

Does that seem right as the reason of the error and how do I find out where in the app the error is occurring?
