Coming to you from my iPad and my old mechanical keyboard plugged in via a USB-C adapter! Go to Settings -> General -> Keyboard -> Hardware keyboards Finally select the language then scroll down to Colemak!

My girlfriend is using the desktop to watch a movie and I wanted to type something up. Never thought I could do it on my iPad but here we are :)

Just wanted to let you all know. Not sure how long this has been possible for; pretty sure it's only possible if you've got a physical keyboard connected via USB or Bluetooth.
