It seemed quite mature for a v1 release. Then again it is hard to judge from an Apple demo but it did look nice.
As an independent developer, I hope the AR kit will make it much easier for me to create something fun and possibly integrate with Siri and other kits. This is what I'm hoping for :D
I know VR is hot right now, but I've always had the thought AR > VR.
That's why the little bit during the demo was interesting. They showed Pokémon go using AR but it was actually doing it correctly, where the Pokémon stayed in position as they moved the camera around.
I was wondering what Pokémon Go would do on android. Will this feature be iOS only or will they implement their own version on android?
