Analyse Apple crash report

Question

My app is rejected during the review and I received a crash report.

They say that the App will crash at startup.

I have symbolized the crash report with Xcode 7.

I can't find the error. Can anybody help me?

Exception Type: EXC_BREAKPOINT (SIGTRAP) this is the exception you're getting. Look through this post: http://stackoverflow.com/questions/2611607/are-exc-breakpoint-sigtrap-exceptions-caused-by-debugging-breakpoints — Eugene Gordin, May 02 '16 at 19:09
You need to fully symbolicate the crash report. The first 3 lines of the stack trace are the ones that point to your app code and they aren't symbolicated. — dan, May 02 '16 at 19:10

These lines are your crash:

The problem is that your crash log is not symbolicated. You can re-symbolicate using the DSYM file that was created when you built the archive for submission. If this DSYM is in your Spotlight search path, then you can re-symbolicate either in the Organizer, or the Devices window (drag the crash onto a device) or on the command line.

Command-line resymbolization is discussed here on Stack Overflow.

DSYM in my Spotlight search path was the solution. – mswyss May 02 '16 at 20:00 — mswyss, May 02 '16 at 20:00

Form Apple Documentation:

Trace Trap [EXC_BREAKPOINT // SIGTRAP]

Similar to an Abnormal Exit, this exception is intended to give an attached debugger the chance to interrupt the process at a specific point in its execution. You can trigger this exception from your own code using the __builtin_trap() function. If no debugger is attached, the process is terminated and a crash report is generated.

Swift code will terminate the program with this exception type if it detects an unexpected condition at runtime such as:

a non-optional type with a nil value a failed forced type conversion Look at the Backtrace of the crashed thread to determine where the unexpected condition was encountered. Additional information may have also been logged to the device's console.
