To preview SwiftUI in Playgrounds, you can take advantage of the new features introduced in Xcode and SwiftUI. Here are some key points from the WWDC sessions that can help you:
-
Xcode Previews: Xcode Previews have been enhanced with a new dynamic linking architecture, which allows you to switch between a preview and build and run without needing to rebuild your project. This makes the workflow smoother and more productive. You can use the
previewablemacro to directly use dynamic properties like state in an Xcode preview, reducing the amount of code you need to write. This is discussed in the Platforms State of the Union session. -
SwiftUI Essentials: SwiftUI automatically provides adaptivity and supports accessibility features. You can preview your app in different contexts, such as dark mode or right-to-left languages, using Xcode Previews. This allows you to see how your views look and feel as you write the code. This is covered in the SwiftUI essentials session.

What's New in Xcode 16: The
previewablemacro can be attached to property wrappers like state, allowing you to use them directly within a preview block. This eliminates the need for wrapper views and simplifies the process of creating previews. This is explained in the What’s new in Xcode 16 session.
By utilizing these features, you can effectively preview and iterate on your SwiftUI designs in Playgrounds, making the development process more efficient and interactive.
