test an app in the device without using USB cable

Hi , in WWDC it was announced, we don't have to connect the device to the mac in order to test apps in the device. Any suggestion on how to do this?

Xcode 9.x touts wireless testing - check it out via the 'Resources/Downloads' link above.

Thank you KMT, I also search and found WWDC17 the session #404 is very helpful
