In 2024, Swift has introduced several significant updates and new features. Here are the key highlights:
-
Swift 6 Language Mode: Swift 6 introduces a new language mode that provides data race safety guarantees, making concurrent programming safer by diagnosing data races at compile time. This mode is opt-in and can be adopted module by module, allowing for gradual migration (Platforms State of the Union).
-
Non-Copyable Types: Swift 6 introduces non-copyable types, which means that by default, all Swift types (whether value types or reference types) are copyable, but you can now define types that cannot be copied, enhancing memory management and performance (What’s new in Swift).
-
Embedded Swift: A new language subset called Embedded Swift has been introduced, which can run on highly constrained systems, expanding the use cases for Swift (What’s new in Swift).
-
C++ Interoperability: Swift 6 improves interoperability with C++, making it easier to integrate Swift with existing C++ codebases (What’s new in Swift).
-
Typed Throws: This feature allows functions to specify the types of errors they can throw, making error handling more precise and predictable (What’s new in Swift).
-
Low-Level Synchronization Primitives: New primitives have been introduced to provide more control over synchronization in concurrent programming (What’s new in Swift).
-
Swift Testing: Enhancements to Swift Testing APIs make it easier to write and maintain tests, improving the overall developer experience (What’s new in Swift).
-
Swift Assist: A new tool called Swift Assist has been introduced to help developers write Swift code more efficiently, with features like predictive completion (Platforms State of the Union).
-
Swift's New Space on GitHub: The Swift project is moving to a new organization on GitHub (swiftlang), which will include the Swift Compiler foundation and many more Swift ecosystem packages (What’s new in Swift).
These updates mark significant advancements in the Swift programming language, making it more powerful, safer, and versatile for a wide range of applications. For a detailed overview, you can watch the session What’s new in Swift.

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.
