So I hit the run button to run the app on the device, but instead of running on the device, I got this dialog:


XCode failed to run my app on my device. I checked my device: the app is uploaded alright, and when I clicked it, it ran well. But why did XCode give me that fail dialog?

I did the following to fix:

1. Go to the dir mentioned in the dialog. Delete the app directory (OpenGLES_Ch2_.....)
2. Delete the uploaded app on the device
3. Restart XCode.

And everything went fine again.
