I'm running Version 4.3.2 (4E2002) and testing in iPhone 5.0 simulator. The simulator opens but i just get black screen the apps not run . Even I tried:-

1.you can delete the App directy under ~/Library/Application Support/iPhone Simulator/6.0/Applications and ~/Library/Developer/Xcode/DerivedData

2.then you can start Xcode ; in the menubar you can find Project -> Clean But its not working.

Do i need to install Xcode again?
