IPhone simulator crashes

Question

I try to run my application in iPhone Simulator, but it starts to work from the very beginning. In addition, applications are launched by default (settings, Safari, etc.). The console shows nothing but

[Session started at 2010-07-23 13:44:07 +0400.]
Failed to launch simulated application: Unknown error.

and there are no crash logs in / Library / Logs / DiagnosticReports. What is the problem?

Xcode version 3.2.2 (also a failure of version 3.2.3).

Answer 1

I saw how Xcode got confused. Sometimes a reboot fixes it.

Otherwise, in the iPhone simulator, try the command "iPhone Simulator> Reset Content and Settings ...". If not, you will have to uninstall and reinstall the dev tools.

: sudo <Xcode>/Library/uninstall-devtools --mode=all
