Preview an Application with the Play To Device App

The Play To Device App

The Play To Device app is a downloadable application that helps with visionOS development. It connects your Apple's visionOS Simulator and/or Vision Pro device to the Unity Editor and displays the visual output from the Editor on the target's device screen. This speeds up iteration time by allowing you to see how a shared world application looks and feels on the target device without creating a build.
