Xcode 4.2 Doesn’t Show Exception Stack Trace in Console

When using Xcode 4.2 for iOS development there’s an annoying bug where any exceptions crash to the main.m file instead of highlighting the line. Luckily you can set a custom breakpoint to restore the old and correct behaviour:

  1. Open the Breakpoint navigator (CMD + 6)
  2. Click the + button in the bottom left
  3. Select Add Exception Breakpoint 
  4. Click Done
