Xcode suddenly stopped running project on hardware: “Could not launch xxx.app: .. No such file..” [closed]

That is really annoying. This error happens in a number of different situations. Sometimes restarting the Xcode, fixes the problem. If not, follow these steps:

Disconnect your device.

Delete the app from your device.

Quit Xcode (Do not just simply close the window, quit it)

Delete derived data folder (~/Library/Developer/Xcode/DerivedData/-gbrvhlvwmpiobxdujegtghggrffp – or something like that)

Now start Xcode once again, connect device and run the project. It should work fine.
