Weekly Newsletter Issue 121

Weekly newsletter summing up our publications and showcasing app developers and their amazing creations.

Welcome to this week's edition of our newsletter.

Last week, we wrote that if you were looking for iPhone Duo support, you’d have to wait for Xcode 27.1.

We love to think that Apple was reading because just a few hours after we hit send, Xcode 27.1 beta arrived, bringing iPhone Duo support with it.

Xcode 27.1 Beta Release Notes | Apple Developer Documentation
Update your apps to use new features, and test your apps against API changes.

Now that developers can finally get their hands on it, we’re starting to see what building for a foldable iPhone actually means in practice.

And, as you might know, there’s more to it than making sure your app looks good on two screens.

iPhone Duo Simulator: Testing and optimizing your SwiftUI app

Antoine walks through testing and optimizing SwiftUI apps for iPhone Duo, starting with adaptive, resizable layouts and progressively adopting features like hinge interactions, vertical toolbars and more.

Learn how to use the iPhone Duo Simulator in Xcode and optimize your SwiftUI app for resizing, adaptive layouts, toolbars, and hinge effects.

SwiftUI Charts: Dynamic Masking

Anton explores dynamic masking in Swift Charts, building a TradingView-style interaction where selecting a point keeps the preceding portion of a chart fully visible while dimming what follows, without slicing the dataset or manually redrawing the chart.

ArrangementView: Think Before You Arrange

Fatbobman breaks down SwiftUI's new ArrangementView, covering its split and overlay modes and where the container genuinely pays off on foldable devices like the iPhone Duo.

Configuring SwiftUI toolbars on iPhone Duo

Natalia explores how to adapt SwiftUI toolbars to iPhone Duo’s vertical layout, showing how to control where toolbar items appear, make custom content respond to its placement, and manage limited space between toolbar actions and tabs.

Control how SwiftUI presents toolbar items and tabs on iPhone Duo with the new iOS 27.1 APIs, from arranging custom labels to prioritizing actions when space is limited.

Indie App of the Week

Tinker

The Home Screen has quietly become something like an apartment: some people leave it with the stock furniture, others spend hours picking the right tinted icons, placing widgets down to the pixel, hunting for the wallpaper that ties the whole thing together.

Tinker, developed by Rasmus, treats that clock as something worth building rather than picking. Backgrounds, hands, and centerpieces are separate layers you combine freely, and how the hands move is its own choice too, a smooth continuous sweep, a mechanical tick, or a chronograph-style motion. The results sit on the home screen as widgets, and if none of the built-in assets fit, you can import your own and build something that exists nowhere else.

Unfortunately, this week we also have some sad news for anyone who has made a visit to Apple Park: the Visitor Center’s 3D model of the campus is gone...

After almost nine years of letting visitors explore Apple Park in augmented reality.

We’ll miss it.

We can’t wait to see what you will Create with Swift.

See you next week!
