GoKawiilXcode 27.1 beta lets developers start building for foldable iPhone Duo
Apple has released Xcode 27.1 beta 1, the first developer tool that supports building apps for the upcoming foldable iPhone Duo. The beta includes a simulator so developers can preview how their apps behave on the device's larger folding display before it ships.
GoKawiil's interpretation of the reporting above, not reported fact.
With iPhone Duo pre-orders starting October 16 and shipping October 23 at $1999, developers now have roughly a month to adapt apps for its unique screen and layout needs. Apps built only for iOS 26 will get basic support, but full optimization requires updating for iOS 27.1, meaning many apps may launch without ideal foldable-specific experiences.
- Xcode 27.1 beta enables initial app development for the foldable iPhone Duo.
- Developers can test layouts using a new iPhone Duo simulator ahead of the device's release.
- iPhone Duo ships October 23 starting at $1999, running iOS 27.1 before merging with iOS 27.2 later.
