Question

I know there’s a lot of posts with the same that problem. I just spent at least 2 hours to read them and I tried everything I saw in the responses but it still doesn’t work. I don’t know what to do anymore. Can someone help me?
I use Xcode 4.2.1

This problem occurs regularly for me, and the solution was always to kill the process named SimulatorBridge.

And to simplify the solution you can add a custom ‘behavior’ in Xcode to do the task by following these steps:

1. Make a shell script file with this command:

   #!/bin/sh
   killall SimulatorBridge
   

2. Save it in ~/Library/Developer/Xcode/UserData/Behaviors/ as KillSimulatorBridge.sh.

3. Open Xcode > Preferences > Behaviors, and add a new behavior to run the shell script:
   

Now, you can run this behavior whenever Xcode hangs while trying to attach to your app, and you can even have a keyboard shortcut to run it.

Hope this helps someone.
