在WWDC 2024中，Swift 6引入了一些重要的新特性和改进。以下是一些关键更新：
-
Swift 6语言模式：Swift 6引入了一种新的语言模式，提供编译时的数据竞争安全性。这意味着在并发程序中，Swift可以帮助检测和防止数据竞争问题。
-
非可复制类型：Swift 6引入了非可复制类型的概念。默认情况下，所有Swift类型（无论是值类型还是引用类型）都是可复制的，但现在可以定义非可复制类型以提高内存管理的效率。
-
嵌入式Swift：Swift 6推出了一个新的语言子集，称为嵌入式Swift，专为在资源受限的系统上运行而设计。
-
C++互操作性：Swift 6增强了与C++的互操作性，使得在Swift中使用C++代码更加方便。
-
类型化抛出：引入了类型化抛出功能，允许开发者在抛出错误时指定具体的错误类型。
-
低级同步原语：Swift 6提供了新的低级同步原语，以支持更复杂的并发编程模式。
这些更新旨在提高Swift的安全性、性能和开发者体验。有关这些特性的更多详细信息，可以查看What’s new in Swift (17:03)的章节。
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 SwiftData
SwiftData makes it easy to add persistence to your app with its expressive, declarative API. Learn about refinements to SwiftData, including compound uniqueness constraints, faster queries with #Index, queries in Xcode previews, and rich predicate expressions. Join us to explore how you can use all of these features to express richer models and improve performance in your app. To discover how to build a custom data store or use the history API in SwiftData, watch “Create a custom data store with SwiftData” and “Track model changes with SwiftData history”.
A Swift Tour: Explore Swift’s features and design
Learn the essential features and design philosophy of the Swift programming language. We’ll explore how to model data, handle errors, use protocols, write concurrent code, and more while building up a Swift package that has a library, an HTTP server, and a command line client. Whether you’re just beginning your Swift journey or have been with us from the start, this talk will help you get the most out of the language.

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.
