Though Pokemon GO had been all about AR (Augmented Reality) for a long time, it’s only recently Niantic is going to tap into Apple’s ARKit framework to bring an even more immersive experience to the table.

With the release of iOS 11, Apple made a huge song and dance regarding its new platform called ARKit. It’s augmented reality for the masses but unlike what Niantic has been doing with Pokemon GO, Apple’s implementation offers extremely smooth tracking along with other features that take realism to a whole new level. Thankfully, after a huge wait, Pokemon GO is bringing AR+ to the table, which takes full advantage of Apple’s ARKit platform. With ARKit now powering the game, there are a lot of features Niantic was able to add to proceedings. For instance, the environment’s scale in which you’re catching a Pokemon can now be definitely felt and you can walk further away or closer to get a real sense of things. That’s not all, Pokemon are now aware of your presence. If you walk up too close to them, you’ll scare them. You don’t wanna do that, do you?
