Xcode 26 RC
Xcode 26 RC includes SDKs for iOS 26, iPadOS 26, tvOS 26, watchOS 26, macOS Tahoe 26, and visionOS 26. The Xcode 26 RC release supports on-device debugging in iOS 16 and later, tvOS 16 and later, watchOS 8 and later, and visionOS. Xcode 26 RC requires a Mac running macOS Sequoia 15.6 or later.
This is up from beta 7, which worked on macOS 15.5. Other than that, it didn’t seem to break anything with my projects. Again, it’s really hard to see from the release notes what’s new in this build.
Xcode 26.0 RC 1 also cannot compile my asset catalog + icon composer icon.
I filed feedback (FB20183399), but this feels completely pointless. As far as I can tell, there’s no workaround so I cannot ship an update using Xcode 26.
Incredibly, the concentric corner APIs don’t have the correct radii on the new iPhone models.
