XCode: Could not launch "APP_X_Y" - 'A' packet returned an error: -1

I'm trying to get my App to work again on the simulator as well as on my device. Before I got this error, I went through an odyssee of XCode signing errors, but right know it seems like I'm really stuck.

The error:

When I try to launch the App on a device, it builds without any errors, but after installing the app I get the error message:

Could not launch "APP_X_Y" - 'A' packet returned an error: -1

Unfortunately I cannot use the Simulator either - it gets stuck at "Attaching to APP_X_Y". You can also take a look at the simulator problem over here - but there is no final solution out there.

What I've done so far:

After different XCode Errors I went through the following Stackoverflow questions, each helping me out with to get to the next level.

  1. Xcode: failed to get the task for process
  2. Profile bug (Error launching remote program: failed to get the task for process XXX.)
  3. Code Sign error: Provisioning profile can't be found
  4. Provisioning Profile "Team" is "Unknown"

In the last step, however I think things got really screwed up: XCode wasn't able to find the provisioning profile anymore, that's why I've deleted my provisioning profile string in my project file, like it is recommended over here: Codesign error: Provisioning profile cannot be found after deleting expired profile

Know I'm struggling with the packet returned -1 error and I cannot find any input out here. Has anyone an idea how to get this to work again?

None of the other answers helped me.. I wasn't able to launch ANY apps in Xcode 5 until I uncluttered my /etc/hosts file - leaving just the basics...

::1                     localhost
127.0.0.1               localhost
255.255.255.255         broadcasthost
fe80::1%lo0             localhost
10.0.1.100              XYZ.com
2001:470:XXXX::100      XYZ.com

You must edit the file as root, btw... sudo nano /etc/hosts

Got the same error when attempting to deploy an application to the third of three connected devices.

All I had to do was quit XCode and restart it and then it worked fine again.

Had the same error. Cleaned build folder, emptied derived data folder, deleted app from device, restarted xcode and it worked again.

If you create a new project from scratch, can this new project connect to the simulator? In that case I suggest just moving over the existing code and settings to a fresh project. I've had to resort to this at least once that I can remember because something fishy had gone wrong with the XCode project file.
