Can not launch the app on device

Question

When i try to launch my application from Xcode to the device, i get this error:

error: failed to launch \'/Users/Luca/Library/Developer/Xcode/DerivedData/myapp-b         


        

Answer 1

I encountered this problem when I tried to run my app on a device with an iOS version below the deployment target set in Target->Summary->Deployment Target. The deployment target was set to 6.0 and my device had iOS 5.1 . Changing the Deployment Target to 5.1 fixed it for me.
