Device debug works but not release

Question

I'm trying to troubleshoot why a release build doesn't work on the device but a debug version does. With a release build, the app starts, default PNG displays and the app dies. I've commented everything out of applicationDidFinishLaunching, which means it isn't a code issue. I see this error in the console:

Mon Jan 18 21:17:39 unknown com.apple.debugserver-43[1579] : error: MachTask::StartExceptionThread (): task invalid, exception thread start failed.

I have it configured as a device release build and have assigned my app store provisioning profile to it. Any ideas on what could be wrong or what the above error means?

Answer 1

You can't use the app store provisioning profile to load onto your device. That will only work for submitting it to Apple. You can make an Ad-Hoc provisioning profile to use, but your Development profile should be enough.

Answer 2

Get Info on your project or target and compare your properties between Debug and Release configurations. Instinct says, something must be different that doesn't need to be different.
