How did I miss knowing about wireless debugging on iOS? You can build, depoly and debug on iOS and AppleTV without a cable! (Keeping the phone charged was another reason to plug in, but with wireless charging, I just have to remember to put the phone down on the charging pad. Easy-peasy!)
That's great, especially for folks like me who are doing AR development, where being tethered by a cable is a pain in the butt.
All you have to do is check the "Connect via network" checkbox in the Devices tab for your device.
Even better for me (as a web developer) is that Safari supports wireless debugging now too!
Happy development, everyone!
