 ## :warning: ARKit 3 Support

-**TL;DR:** If you want to checkout the latest and greatest features in ARKit 3, use this `master` branch, Xcode 11 beta, and a device running iOS 13 beta. Otherwise, see the [2.1 branch](https://github.com/Unity-Technologies/arfoundation-samples/tree/2.1), which only lacks support for the new ARKit 3 features.

-The `master` branch includes support for ARKit 3, which is still in beta and requires Xcode 11 beta and iOS 13 beta. If you try to build the `master` branch with Xcode 10, you will get these linker errors:

 The [2.1 branch](https://github.com/Unity-Technologies/arfoundation-samples/tree/2.1) is compatible with Xcode 9 and 10 and only lacks the new ARKit 3 features.

-ARFoundation 2.2 provides interfaces for ARKit 3 features, but only Unity's ARKit XR Plugin 2.2 package contains _support_ for these features and _requires_ Xcode 11 beta and iOS 13 beta. Unity's ARKit XR Plugin 2.2 is not backwards compatible with previous versions of Xcode or iOS. Unity's ARKit XR Plugin 2.1 will work with the latest ARFoundation (it just doesn't implement the ARKit 3 features).

 While Xcode 11 & iOS 13 are in beta, we will continue to maintain *both* the 2.2 and 2.1 versions of the packages.
