On the same day Apple revealed its first foldable iPhone, it also quietly turned toward the developers who must make software fit the new shape, opening a hub of labs, workshops, guides and videos. It is a familiar rhythm in the life of a platform: the object is unveiled to the public, and then the work of making it livable passes to the many hands that build for it. With the Duo due in October, that handoff is happening on a short clock, and what unfolds in the coming weeks will show how readily the software world can bend to a new kind of screen.
Apple Releases iPhone Duo Developer Resources, Including Labs, Workshops and Design Guidance
Apple opened a page for the people who must make apps work on it.
Mark
Why does a developer page matter on the day a phone is announced?
Mimi
Because a new device is only as good as its apps. Apple put labs, workshops, videos and docs online the same day, with an October release ahead.
Mark
What's actually scheduled?
Mimi
Group Labs on September 16 and 17, then Q&As on September 23 covering Photos and Camera, SwiftUI and UIKit, two sessions each. Workshops worldwide start later this month.
Luke
And the tools? Can developers build for it today?
Mimi
Not fully. The Xcode 27.1 beta and the two guides are listed as upcoming, not released.
Mark
What do the video titles suggest?
Mimi
Adaptive layouts, multiple displays and scenes, and a camera experience built for the device. Those look like the main areas of work.
Luke
Worth being careful there. The titles hint at the focus, but we haven't seen the content, so we don't know what Apple will require of apps.
Mark
Anything else unknown?
Luke
The workshop locations and exact dates weren't given, and nothing here says how much work existing apps will need.
Mimi
Fair. The first labs next week should start to answer that.
The Pulse
- Apple unveiled the iPhone Duo, its first foldable, at the 'Surprise and Shine' event, setting a deadline that leaves developers only weeks to adapt.
- Developers face a scramble to rework layouts, scenes and camera experiences for a device that folds and unfolds.
- Apple is answering with Group Labs on September 16 and 17, Q&A sessions on September 23, and hands-on workshops launching around the world.
- Six WWDC-style videos, a Designing for iPhone Duo guide and an Xcode 27.1 beta are still coming, and they will reveal how much ground remains to cover before October.
On the same day Apple revealed its first foldable iPhone, it also quietly turned toward the developers who must make software fit the new shape, opening a hub of labs, workshops, guides and videos. It is a familiar rhythm in the life of a platform: the object is unveiled to the public, and then the work of making it livable passes to the many hands that build for it. With the Duo due in October, that handoff is happening on a short clock, and what unfolds in the coming weeks will show how readily the software world can bend to a new kind of screen.
Apple unveiled its first foldable iPhone, the iPhone Duo, at its "Surprise and Shine" event, where it appeared alongside the iPhone 18 Pro and Pro Max, the Apple Watch Series 12 and Ultra 4, and AirPods 5. The same day, Apple opened a developer page called "Get ready for iPhone Duo," aimed at the people who will have to make their apps work on the new device. Designers can already find the Duo's dimensions and visual assets in the Design Resources portal.
The page lays out a schedule of help. Two Group Labs are set for September 16 and 17, and on September 23 Apple will host Q&A sessions covering Photos and Camera, SwiftUI and UIKit, each offered at two times. Hands-on workshops, focused on resizing apps for every screen size, will begin later this month in cities around the world.
Several resources are still on their way: a beta of Xcode 27.1, a guide called "Designing for iPhone Duo," and another called "Preparing your app for iPhone Duo." Six WWDC-style videos complete the package, covering design, preparation, adaptive layouts, multiple displays and scenes, and camera experiences. Together they map the work ahead.
With the Duo arriving in October, developers have little time. The coming Xcode beta, the guides and the September labs will be the first real opportunity to bring questions directly to Apple.
On the same day Apple showed the world its first foldable iPhone, it also opened a page aimed at the people who will have to make apps work on it. The page is titled "Get ready for iPhone Duo," and it gathers labs, workshops, documentation and videos for developers.
The device itself, the iPhone Duo, was announced at Apple's "Surprise and Shine" event. It shared the stage with the iPhone 18 Pro and iPhone 18 Pro Max, the Apple Watch Series 12 and Ultra 4, and the AirPods 5 with Active Noise Cancellation. Apple also posted the Duo's assets to its Design Resources portal, so designers can begin working with the hardware's dimensions and look.
The developer page lays out a schedule. Two iPhone Duo Group Labs are set for September 16 and 17. A week later, on September 23, Apple will hold Q&A sessions on three subjects: Photos and Camera, SwiftUI, and UIKit. Each topic gets two sessions at different times that day.
Apple is also taking the effort on the road. iPhone Duo Workshops will be held around the world, starting later this month. Apple describes them as hands-on sessions where developers can optimize their apps and "explore resizability for all screen sizes."
The page also points to tools and documentation that are listed as upcoming: a beta of Xcode 27.1, a guide called "Designing for iPhone Duo," and another called "Preparing your app for iPhone Duo."
Six videos, styled like WWDC sessions, round out the list: "Design for iPhone Duo," "Prepare your app for iPhone Duo," "Raise the bar with iPhone Duo," "Strike a pose with adaptive layouts on iPhone Duo," "Leverage multiple displays and scenes on iPhone Duo," and "Build a great camera experience for iPhone Duo." The titles alone sketch the main areas of work: layouts that adapt, apps that handle multiple displays and scenes, and camera experiences built for a folding device.
The timing matters because the Duo is due in October, leaving developers only weeks to adapt. What to watch next is the arrival of the Xcode 27.1 beta and the two design and preparation guides, along with the September 16 and 17 labs, which will be the first live chance to put questions to Apple.
