A build only device cannot be used to run this target

Question

I get this error when I trying to test an app.

A build only device cannot be used to run this target.

No supported iOS devices are available

Answer 1

i meet a problem that only "Generic iOS Device" can be choosed. and when i run ,it says "A build only device cannot be used to run this target.No supported iOS devices are available. Connect a device to run your application or choose a simulated device as the destination "

and my solution for the problem is selecting Build Settings ---> Deployment ----->IOS Deployment Target---->choose a lower version like 8.0,

and i found the simulator come out and can be chosen.
