What's New in Swift
Swift 6 Language Mode
- Data Race Safety: Swift 6 introduces a new language mode that provides data race safety guarantees, helping developers write correct concurrent programs. This is a significant improvement for ensuring safety in concurrent programming.
- Non-Copyable Types: Swift 6 introduces non-copyable types, which can help optimize performance and memory usage by preventing unnecessary copies of data.
- Embedded Swift: A new language subset called Embedded Swift is introduced, which can run on highly constrained systems, expanding the use cases for Swift.
Improvements and Features
- Concurrency Model: Continued refinements to the concurrency model, including complete concurrency checking in Swift 5.10 and improvements in Swift 6.
- C++ Interoperability: Enhancements to interoperability with C++, making it easier to integrate Swift with existing C++ codebases.
- Typed Throws: Introduction of typed throws, allowing functions to specify the types of errors they can throw, improving error handling.
- Low-Level Synchronization Primitives: New primitives for low-level synchronization, providing more control over concurrent programming.
Ecosystem and Tools
- Swift Package Manager: Ongoing improvements to the Swift Package Manager, making it easier to manage dependencies and build Swift projects.
- Swift Testing: New Swift testing APIs designed to be more productive and easier to use.
- Swift Data: Introduction of Swift Data, a lightweight API for modeling and persisting app information.
Community and Cross-Platform
- GitHub Migration: The Swift project is moving to a new organization on GitHub (swiftlang), which will include the Swift Compiler foundation and many more ecosystem packages.
- Cross-Platform Development: Continued support for cross-platform development, including improvements to the Swift extension for VS Code and bi-directional interoperability with C.
SwiftUI Integration
- SwiftUI Enhancements: SwiftUI has been updated to integrate seamlessly with the new Swift 6 language mode, including improvements to scrolling, custom containers, and 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.
