Xcode crawls to halt when using breakpoints with expressions on iOS device


  • Subject: Xcode crawls to halt when using breakpoints with expressions on iOS device

Hi,

on Xcode 4.6.2 (also 4.6.1, not sure if it was there earlier) whenever I use an auto-continue debugger command action that outputs something using NSLog() like

  expr (void)NSLog(@"My object %@", obj);

the app completely freezes as soon as the breakpoint is hit the first time. It appears as if the app had crashed, but it didn't.

To get out of that freeze, I need to set a normal breakpoint into the code (doesn't matter where). As soon as I set the breakpoint, Xcode beachballs for 30 seconds. After that it works fine, so does the expression breakpoint and the logging.

This doesn't happen on the simulator, just when debugging on the device (iPhone 4S in this case).

Has anyone else seen this?

Regards
Markus
