Apple is now accepting submissions of iPhone Duo-optimized apps and games built with Xcode 27.1. Developers can submit through App Store Connect, where their product page will display a badge indicating optimization for the device. Starting April 2027, all submitted apps must include iPhone Duo screenshots.
Apple released Xcode 27.1 Release Candidate 1 to support building and testing for the new device. Recompiling existing apps with Xcode 27.1 adds iPhone Duo support, and developers can use Device Hub to preview app behavior across poses and orientations. Apple provided resources including design guidance, templates, asset management, and preview/screenshot specifications.
In-person iPhone Duo workshops are being held over the next few days. The iPhone Duo will be available for pre-order starting October 16, with deliveries and in-store availability beginning October 23. Customers can prepare for pre-orders starting October 12.
