I know it's extremely unlikely, I do wish Apple would move its phones and tablets to use USB-C too.
1. They already have a lot of accessories for lightning and they would kinda lose that sweet 30 % MFi for 3rd party lightning accessories
2. A lot of people who don't know why USB C is great will probably bitch about how Apple is changing the port on the iPhone _again_, like they did when they switched from 30 pin to lightning. Could be a PR nightmare
