Apple has opened App Store submissions for apps designed or updated for the iPhone Duo. The move gives developers time to prepare their software before the new foldable iPhone reaches customers.
Developers still need to pass Apple’s standard App Store review process. However, early submissions could help more optimized apps become available when the device launches on October 23.
For developers, the opening creates an important opportunity. Apps that take advantage of the folding display could attract greater attention during the device’s first days on sale.
Xcode 27.1 Adds iPhone Duo Support
Apple is directing developers to Xcode 27.1 to prepare their software. The development environment adds specific support for the iPhone Duo.
Moreover, developers can use Device Hub to preview how their apps will appear on the new hardware. This step should help them adapt interfaces for the device before submitting updates.
Developers submitting an iPhone Duo version must also update their screenshots and app preview specifications. Therefore, App Store listings can better represent how software looks on the foldable device.
iPhone Duo Screenshots Become Mandatory in 2027
Apple has also introduced a future requirement for App Store submissions. Starting in April 2027, submitted apps and games will need to include screenshots for the iPhone Duo.
The requirement signals that developers will eventually need to account for the new device when preparing App Store materials. For now, though, developers can focus on getting optimized versions ready for launch.
October Launch Timeline Takes Shape
According to the source, Apple will begin iPhone Duo pre-orders on October 16. The device will then arrive in stores and begin shipping to customers on October 23.
