AR Foundation Samples

Example projects that use AR Foundation 2.2 and demonstrate its functionality with sample assets and components.

This set of samples relies on four Unity packages:

ARSubsystems
ARCore XR Plugin
ARKit XR Plugin
ARFoundation

ARSubsystems defines an interface, and the platform-specific implementations are in the ARCore and ARKit packages. ARFoundation turns the AR data provided by ARSubsystems into Unity GameObjects and MonoBehavours.

The master branch is compatible with Unity 2019.1 and later. For 2018.4, see the 1.5-preview branch. ARFoundation 1.5 is functionality equivalent to 2.2. The only difference is the version of Unity on which it depends.

⚠️ 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 3, and a device running iOS 13 beta. Otherwise, see the 2.1 branch, 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 3 and iOS 13 beta 3. If you run these samples on a pre-iOS 13 device, your app will crash on startup with this message:

dyld: Symbol not found: _OBJC_CLASS_$_ARMatteGenerator

The 2.1 branch 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 3 and iOS 13 beta 3. 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.

The same is also true for Unity's ARKit Face Tracking package 1.1: it requires Xcode 11 beta 3 and iOS 13 beta 3.

This table shows the latest version of Unity's ARKit XR Plugin and its Xcode and iOS compatibility:

Unity ARKit XR Plugin	Unity ARKit Face Tracking	Xcode Version	iOS Version
2.2	1.1	11 beta 3	13 beta 3
2.1	1.0	9 or 10	11 or 12

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+.
