What's New in Swift

Overview

Swift has reached a significant milestone, celebrating its 10th anniversary. Over the years, Swift has evolved to become a powerful, modern, and safe programming language, suitable for both newcomers and experts. This year, Swift 6 introduces several new features and improvements.

Key Updates in Swift 6

New Language Mode: Swift 6 introduces a new language mode that provides data race safety guarantees, enhancing the safety of concurrent programs.
Non-Copyable Types: Swift 6 introduces non-copyable types, which are not copyable by default, whether they are value types or reference types.
Embedded Swift: A new language subset called Embedded Swift is introduced, which can run on highly constrained systems.
Concurrency Improvements: Significant improvements have been made to data race checking and concurrency checking, ensuring better safety and performance.
C++ Interoperability: Enhanced interoperability with C++ allows for more seamless integration between Swift and C++ codebases.
Typed Throws: Introduction of typed throws, which allows functions to specify the types of errors they can throw, improving error handling.
Low-Level Synchronization Primitives: New primitives for low-level synchronization have been added to the language.

Swift Ecosystem

Swift Package Manager: Continues to evolve, making it easier to manage dependencies and build Swift projects.
Swift Testing: New testing APIs designed for Swift make it easier to write and maintain tests.
Swift Data: Introduced last year, Swift Data helps model and persist app information using a lightweight API.

Swift's New Space

Swift will be moving to a new organization on GitHub, managed by the Swift project. This includes the Swift Compiler foundation and many more Swift ecosystem packages.
