In the "What's new in Swift" session at WWDC, three main areas of focus for Swift 6.2 are:
-
Development Workflow Improvements: Swift 6.2 introduces enhancements to the development workflow, including writing, building, and debugging code. Notably, the Swift extension in VS Code is now officially verified and distributed by Swift.org, with features like background indexing enabled by default for SwiftPM projects. This improves editor features such as "Jump to Definition" (What’s new in Swift).
-
Concurrency and Performance Enhancements: Swift 6.2 makes concurrency more approachable and enhances performance. It introduces a new language mode that provides concurrency safety guarantees, turning data races into compile-time issues. This helps improve the correctness and safety of your code (What’s new in Swift).
-
Embedded Swift and Security: Swift 6.2 expands the use of Embedded Swift, a subset of Swift for highly constrained environments like firmware for embedded devices. It also introduces Strict Memory Safety, requiring explicit acknowledgment of unsafe API usage in source code, enhancing security (What’s new in Swift).
These updates aim to make Swift more productive and safer for developers across various platforms and use cases.
What’s new in Swift
Join us for an update on Swift. We’ll talk about workflow improvements that make you more productive, and new and modernized library APIs for fundamental programming tasks. We’ll show examples of Swift adoption throughout more layers of the software stack. Finally, we’ll explore new language features for both improving approachability of concurrency, and achieving peak performance when you need it.
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.
