In 2024, Apple introduced several new features and improvements to macros in Swift. Here are the key updates:
-
Previewable Macro: This new macro can be attached to property wrappers like
@State, allowing you to use them directly within a preview block. This reduces the need to write wrapper views and simplifies the code required to see your UI live in Xcode previews. For more details, you can refer to the session What’s new in Xcode 16 (03:04). -
Preview Modifier: This new API makes it easier to share environment or data for previews, reducing duplicate code and enabling the preview system to cache the data. This helps in creating more efficient and reusable previews. More information can be found in the same session What’s new in Xcode 16 (03:04).
These updates are part of the broader improvements in Swift and Xcode aimed at enhancing the developer experience by making code more expressive and reducing boilerplate. For a comprehensive overview of what's new in Swift, you can check out the session What’s new in Swift (00:07).

Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
