How Can I symbolicate the coding error?

The following is the thread that causes my app to crash when it resumes from idle. I tried plugging in my iPhone, going to organizer, clicking on the iPhone, and going to device logs. But when I click Re-Symbolicate, nothing happens. Please advise and provide detailed directions to symbolicate so I can find the cause of the crash. I tried looking up how to symbolicate but I was unsuccessful.

I think that you have tested in Release mode. In that mode, the default value of "Strip Debug Symbols During Copy" is YES.

If this option is enable (YES), you must have the .dsym file in order to symbolicate, other wise, you have to disable it (NO).

Search google about "Strip Debug Symbols During Copy".

  1. Symbolication doesn't work because the dSYM and app binary that caused the crash cannot be found using Spotlight or either of the two files is missing.

  2. Symbolication would only reveal that frame #14 is a call to main.m, which doesn't help you.

  3. The crash is caused by an exception. To find the cause of the crash you would need to have the Application Specific Information block in the report that tells you which exception was raised, and also the Last Exception Backtrace which would show you where the exception happened in the code. Both parts are usually missing in iOS crash reports from Apple.

To find the cause of the crash you have to:

  1. Add an exception breakpoint.
  2. Start the app with the debugger in Xcode running (Menu Product - Run)
  3. Reproduce the scenario that triggered the crash.
