iOS Simulator Crash Logs


  1. Run your App with Xcode to install the App to iOS Simulator
  2. Launch your App on Simulator without Xcode
  3. reproduce steps for crash
  4. the Crash log should show up under this directory

    ~/Library/Logs/DiagnosticReports/


It appears if you aren't running Xcode (mine is 4.5.2) but just the simulator (mine is 6.0) that when an app crashes it does save a crash report. To view it bring up the Application/Utilities/Console and

(1) make sure it shows the log list (see top left of console to make sure not hidden)

(2) under "DIAGNOSTIC AND USAGE INFORMATION" there is a "User Diagnostic Reports" that if you open up should have your crash reports

(3) the area on the right of the console has the log


A Crash log is just an output of what the debugger already gives you. When you are running in the simulator attached to the debugger, and you hit the crash, you can view the back trace information in the debug navigator (default key binding is cmd+5)
