This distinciton is temporary. Once iOS 13 is no longer in beta, the ARKit package is expected to work with all versions of Xcode 9+ and iOS 11+.
#### Which branch should I use?
If you want to checkout the latest and greatest features from Apple, 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.
## Instructions for installing AR Foundation
1. Download the latest version of Unity 2019.1 or later.
