Yes you heard it right, Wireless Debugging 👻 We were waiting for this moment and finally Apple announced wireless debugging feature on Xcode 9 at WWDC 17.
Cut the Cord
Choose any of your iOS or tvOS devices on the local network to install, run, and debug your apps — without a USB cord plugged into your Mac. Simply click the ‘Connect via Network’ checkbox the first time you use a new iOS device, and that device will be available over the network from that point forward. Wireless development also works in other apps, including Instruments, Accessibility Inspector, Quicktime Player, and Console.
