XCode Locks Up When Launching the iOS Simulator

Question

Lately when I have been deploying any iOS application to the simulator (iPad or iPhone), XCode locks up (Not Responding) and the simulator simply displays a black screen. I have to force quit both.

Steps I have taken so far towards a resolution:

1. Clean
2. Reset the Simulator
3. Deleted the simulator folder
4. Reinstalled XCode from the App Store
5. Reinstalled XCode from the developer center

Has anyone else encountered this? Any suggestions for a solution?

Other info:

• OSX Lion 10.7.3
• XCode 4.3.2
• Shibboleet

Thanks in advance for any help.

Answer 1

I had this problem and was able to continue by:

1) Edit the run scheme by clicking on the first part of the App name to the right of the "Stop" button to bring down the scheme list and click "Edit Scheme..."

2) Click on the Run item and change the debugger from LLDB to GDB.

3) Run

I think the problem was that I validated the settings and it offered to automatically change the debugger from GDB and LLDB and I clicked "OK" because the advisor message sounded very self-assured.

Enjoy.
