Apple has announced new minimum SDK requirements for App Store submissions starting April 28, 2026 . If you're working on an iOS app, it's time to plan your upgrade.

What’s Changing?

All apps submitted to App Store Connect must be built with the latest SDK versions:

iOS / iPadOS → SDK 26 or later

tvOS → SDK 26 or later

visionOS → SDK 26 or later

watchOS → SDK 26 or later

Required Upgrades

To meet these requirements, ensure your development environment is updated:

macOS → Version 26.4 (Tahoe)

Xcode → Version 26

Common Issue After Upgrade
