iPhone Duo Workshops

In person · worldwide

Hands-on sessions at Apple Developer Centers

Apple says these workshops let you optimize your apps and explore resizability for all screen sizes. Timing is listed as later this month (September 2026) — dates and cities are published on Apple's page as they open.

Tools and documentation

Xcode 27.1 beta — the only SDK that puts your app edge-to-edge on the inner display. Apple lists it as coming later this month; as of today the iOS 27.1 release notes are not published yet, so you cannot test on the Duo simulator until it drops.
Designing for iPhone Duo — Apple's HIG guidance, live now: how apps adapt when the device is opened, closed or partially folded, and how the under-display camera moves your UI aside.
Preparing your app for iPhone Duo — Apple's developer guide, listed as coming soon. Until then, the six Tech Talks below and our written notes cover the same ground.

Times are taken from Apple's Get ready for iPhone Duo page, which lists them in Pacific Time; UTC is simply PT + 7 hours (PDT) in September.
