Apple has announced that the new App Store, which will support the Vision Pro headset, will default to including apps from iPhones and iPads that are compatible with this new store. The new App Store will launch alongside the beta update of visionOS, towards the end of the year.
Apple explains that most of the frameworks available on iPadOS and iOS are already included in visionOS, allowing almost all iPad and iPhone apps to run on visionOS without any additional work from developers. However, if an app encounters compatibility issues, developers will be notified through App Store Connect and will need to make the necessary updates to ensure compatibility with visionOS. Developers can test compatibility using the visionOS simulator on Xcode 15 beta.
Furthermore, Apple recommends that developers who want to provide a complete immersive experience on visionOS can create apps using the visionOS SDK. This SDK allows developers to incorporate 3D objects into their apps, specifically designed for eye and hand input.
TLDR: Apple has announced that the upcoming App Store for the Vision Pro will include compatible apps from iPhones and iPads by default. Developers can expect most apps to run on visionOS without additional work, but may need to make updates if compatibility issues arise. Testing can be done using the visionOS simulator on Xcode 15 beta. Additionally, developers can utilize the visionOS SDK to incorporate 3D objects for eye and hand input.
