ARKit is one of the biggest changes in iOS 11. Under the hood, Apple is about to transform the iPhone into a very capable augmented reality device. Felix Lapalme‏ has been looking at assets in the Maps app package to find out if the company is going to leverage augmented reality for turn-by-turn directions.

So I wouldn’t be surprised if Apple talked about some feature that lets you walk around an airport to find the nearest coffee shop using augmented reality. It would look like this app developed by Andrew Hart‏, a developer who has been playing around with new frameworks:
