Apple hasn’t even put iPhone Duo in customers’ hands yet, but it’s already telling developers: start building.
A new email from Apple tonight is landing with a pretty straightforward message — iPhone Duo is coming, and developers need to be ready for it.
The email, titled “Start building for iPhone Duo,” points developers towards three things they can use right now.
First up is Xcode 27.1 beta, giving developers the tools they need to start working with iPhone Duo and its new screen configuration.
Then there are updated Figma and Sketch design kits available through Apple’s Design Resources, giving designers the official components and layouts needed to start thinking about how their apps should look across Duo’s displays.

And Apple isn’t stopping at software and design files.
It’s also encouraging developers to sign up for workshops covering how to optimise apps and build customised experiences for different screen sizes.
That last part is probably the most interesting.
Because iPhone Duo isn’t simply another iPhone with a bigger display. Developers are going to have to think about how an app behaves as that display changes shape and configuration — and Apple clearly wants developers experimenting with that before launch day.
The timing is telling, too.
Apple is effectively giving developers a head start before iPhone Duo reaches the public, rather than waiting for launch day and hoping everyone catches up.
The hardware might still be sitting in Apple Stores waiting for the October 16 pre-sale, and launch day.
But it appears the real software work has only just begun.
