Per Apple’s policy, starting April 2025, all visionOS apps uploaded to the App Store Connect must be built with visionOS 2 SDK. As such, Unity will be deprecating support for visionOS 1.x starting April 2025.
Developers can continue to access Unity’s latest 1.3.12 packages, including Play to Device, but there will no longer be further development on the 1.x packages beyond critical fixes.
We recommend developers to migrate to the 2.x packages on Unity 6, where Unity will continue feature development and bug fixes for visionOS 2, including for Play to Device.
