Apple announced ARKit 2 at WWDC 2018. This also aided the release of a new open file format called USDZ for deeper AR integration throughout iOS.
ARKit 2 allows developers to integrate shared experiences, object detection, image tracking, and persistent AR experiences centered around the specific location to make AR apps even more dynamic.
The new file format is in collaboration with Pixar. The USDZ file format is optimized for sharing in apps like Messages, Safari, Mail, Files, and News. Called AR Quicklook, the feature allows users to place 3D objects into the real world using USDZ.
ARKit 2 and USDZ file format both are included in iOS 12 beta and will be available this fall as part of a free software update on compatible iOS 12 devices. iPhone 6s and later, all iPad Pro devices, iPad 5th generation, and iPad 6th generation to be specific.
