- OS X 10.5.7 (genuine Mac)
- Xcode 3.1.3
- iPhone SDK 3.0
When I try to execute my iPhone application in simulator, I get the dreaded error message:
Failed to launch simulated application: Unknown error.
My application has two targets, but this error occurs on both of them.
When error occurs, the simulated OS hangs — it displays black screen and no longer responds on any input. Simulator application itself does not hang — all menus are active.
All other applications I've tried running (mostly Apple samples) do work fine. Purging of caches, rebooting and howling on the Moon did not helped. Rebuilding project from scratch did not helped either. I guess I have to do it again in smaller steps.
Meanwhile, are there any other things to try than these below?
- Xcode | Empty Caches...
- Delete directory /Library/Caches/com.apple.DeveloperTools.###
- Full rebuild
- Reboot
- Change the product name (it did not contain any spaces anyway)
- Create new project and configure it manually from scratch
