- Summary: Apple announced iPhone Duo with a 7.6-inch inner display and a 5.4-inch outer display, and states both share one aspect ratio. Apple states iOS 27 adds Split View multitasking and a second window of the same app, and that developers adapt through new and updated APIs in the latest SDKs, with iPhone Duo support in Device Hub in Xcode stated as coming. Pre-orders open 2026-10-16 and availability begins 2026-10-23.
- Why it matters: Every iOS app gains a second layout target, and the stated ship dates set the window for that adaptation work.
- Follow-up: Track the shipped SDK APIs and Device Hub support once the device is available.
