Xcode 27.1 beta arrives with iPhone Duo design kits
Apple published both on 18 September, along with guidance on preparing apps.
Xcode 27.1 beta is available to download, and design kits for the iPhone Duo have been published in Figma and Sketch formats. Apple announced both on 18 September 2026. Of the two, the beta is the one that gates building and testing against the new hardware.
Apple has also published guidance on preparing apps for the iPhone Duo. The announcement does not enumerate what an existing app needs to change — it points to separate documentation rather than listing an API surface, so the scope of the work is not visible from the release note itself.
Details are on the Apple Developer News page.
