App Store Distribution – Minimum Deployment Targets (iOS, macOS, tvOS, watchOS) with XCode 26

Hello Team,

We’ve confirmed Apple’s current minimum OS requirements for Xcode 26:

iOS 15 – 26

iPadOS 15 – 26

tvOS 15 – 26

watchOS 8 – 26

visionOS 1 – 26

macOS 11 – 26

Are we correct in understanding that any builds targeting below these versions are no longer accepted by the App Store and may fail to launch for users on older systems? Like this https://developer.apple.com/forums/thread/821370?answerId=882822022#882822022

For Steam macOS distribution, can older macOS targets still be supported, or should we align strictly with Apple’s minimums?

Thank you and best regards,

Phong
