Tools and documentation
- Xcode 27.1 — release candidate. The SDK that puts your app edge to edge on the inner display, and the build that carries the Duo Simulator runtime. Apple's Get ready page lists it as a release candidate; our simulator notes cover what the runtime still does not do.
- Preparing your app for iPhone Duo — Apple's readiness guide is live (our earlier note on this page had it as coming soon). It is a three-step checklist: run the resizability skill, remove
UIScreen.mainand orientation assumptions, then test resizing. We wrote it up in Apple's three steps. - Designing for iPhone Duo — Apple's HIG guidance: how apps adapt when the device is opened, closed or partially folded, and how the under-display camera moves your UI aside. Figma and Sketch design kits for the device are available from Apple Design Resources.
- New camera documentation. Choosing a camera by the direction it faces and Registering a camera capture accessory on iPhone Duo — both written up in which way that camera faces.
- App Store assets. With submissions open, Apple's asset best practices and its screenshot and app preview specifications are the pages to read before uploading Duo-size media.
- The six Tech Talks. Every official session is embedded on our home page, with written notes in the blog.
Times are taken from Apple's Get ready for iPhone Duo page and the October 2026 Hello Developer newsletter, which list them in Pacific Time; the UTC column is our conversion (PT + 7 hours while PDT is in effect, which covers all of October). Where Apple lists a session without a time, we leave it out rather than guess.
