在WWDC 2024上，Swift有一些重要的更新：
-
Swift 6：Swift 6引入了新的语言模式，提供数据竞争安全性，扩展了Swift的安全保证到并发程序中。此外，还引入了一个新的语言子集，称为嵌入式Swift，可以在高度受限的系统上运行。
-
非可复制类型：Swift 6引入了非可复制类型，所有Swift类型，无论是值类型还是引用类型，默认都是可复制的。非可复制类型的引入为开发者提供了更多的控制。
-
Swift Testing：一个全新的测试框架，名为Swift Testing，被引入。它提供了表达性强的API，使编写测试变得简单。
-
C++互操作性：Swift 6继续改进与C++的互操作性，使得在Swift中使用C++代码更加容易。
-
低级同步原语：Swift 6引入了低级同步原语，进一步增强了并发编程的能力。
-
数据竞争检查：在Swift 6中，数据竞争检查得到了显著改进，以确保代码的安全性。
这些更新使得Swift在安全性、性能和开发者体验方面都有了显著的提升。

Platforms State of the Union 5-Minute Recap
Watch a quick recap of the newest advancements on Apple platforms.
Migrate your app to Swift 6
Experience Swift 6 migration in action as we update an existing sample app. Learn how to migrate incrementally, module by module, and how the compiler helps you identify code that’s at risk of data races. Discover different techniques for ensuring clear isolation boundaries and eliminating concurrent access to shared mutable state.
What’s new in SwiftUI
Learn how you can use SwiftUI to build great apps for any Apple platform. Explore a fresh new look and feel for tabs and documents on iPadOS. Improve your window management with new windowing APIs, and gain more control over immersive spaces and volumes in your visionOS apps. We’ll also take you through other exciting refinements that help you make expressive charts, customize and layout text, and so much more.
What’s new in Swift
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.
What’s new in UIKit
Explore everything new in UIKit, including tab and document launch experiences, transitions, and text and input changes. We’ll also discuss better-than-ever interoperability between UIKit and SwiftUI animations and gestures, as well as general improvements throughout UIKit.
