Xcode 4 hangs at “Attaching to (app name)”

Question

I just upgraded to Xcode 4 and for some reason my app won\'t run in the simulator or iOS device. It was working perfectly in Xcode 3, but all of a sudden now when I press ru

Answer 1

All of the above suggestion didn't resolve my problem. After I added the Resources folder and and compile, it hangs on attaching to app-name. I removed Resources folder, still hang. I removed the project and recreate a new one ( with the same name ) but still having problem. If it was different name then it's ok. I restarted the OS but still doesn't help.

To solve the issue, I did the following: 1. ps -ef | grep Xcode, and kill all the "Xcode" processes. 2. Reset the content of Simulator, and quit the Simulator. 3. Product > Clean to clean up the build. 4. Compile and run the product. It should work at this point.

Hope it helps some else having this similar issue.
