SSWG 2021 Annual Update
Since the last update from the SSWG, the Swift on Server ecosystem has continued to grow and expand. To start, the SSWG is very happy to welcome three new members: Adam Fowler Fabian Fett (Apple) Patrick Freed (MongoDB) Adam, Fabian and Patrick officially joined the SSWG on September 3rd. Fabian replaced Johannes Weiss who has completed a three year stint on the SSWG. We are extremely grateful for
ABI Stability and More
It has been a longstanding goal to stabilize Swift’s ABI on macOS, iOS, watchOS, and tvOS. While a stable ABI is an important milestone for the maturity of any language, the ultimate benefit to the Swift ecosystem was to enable binary compatibility for apps and libraries. This post describes what binary compatibility means in Swift 5 and how it will evolve in future releases of Swift. You may ask:
Introducing the sourcekitd Stress Tester
Sourcekitd provides the data backing key editor features like code completion, semantic highlighting, and refactoring for Swift files in both Xcode and the recently announced SourceKit-LSP. To help improve its robustness, we’re introducing a new tool, the sourcekitd stress tester, that over the past few months has helped find 91 reproducible sourcekitd crashes, assertion failures, and hangs. This
Swift 5 Exclusivity Enforcement
The Swift 5 release enables runtime checking of “Exclusive Access to Memory” by default in Release builds, further enhancing Swift’s capabilities as a safe language. In Swift 4, these runtime checks were only enabled in Debug builds. In this post, I’ll first explain what this change means for Swift developers before delving into why it is essential to Swift’s strategy for safety and performance. B
Swift.org - REPL Support for Swift Packages
The swift run command has a new --repl option which launches the Swift REPL with support for importing library targets of a package. The Swift distribution comes with a REPL for the Swift language. The Swift REPL is a great tool for experimenting with Swift code without needing to create a throwaway Swift package or Xcode project. The REPL can be launched by running the swift command without any a
Swift 4.0 Released!
Ted Kremenek is a member of the Swift Core Team and manages the Languages and Runtimes group at Apple. Swift 4 is now officially released! Swift 4 builds on the strengths of Swift 3, delivering greater robustness and stability, providing source code compatibility with Swift 3, making improvements to the standard library, and adding features like archival and serialization. You can watch a quick ov
Swift Source Compatibility Test Suite Now Available
We are pleased to announce the release of a new Swift source compatibility test suite as part of the effort to maintain source compatibility in future Swift releases. The source compatibility test suite is community driven, meaning open source project owners can submit their projects for inclusion in the suite. Instructions for adding open source projects to the test suite can be found in the Swif
Swift 3.1 Released!
March 27, 2017 Swift 3.1 is now officially released! Swift 3.1 is a minor release that contains improvements and refinements to the Standard Library. Thanks to efforts by IBM and other members of the community, it also includes many updates to the Linux implementation of Swift. There are also a number of updates to Swift Package Manager. Language Updates Swift 3.1 is a minor language release. It i
Faster Mix-and-Match Builds with Precompiled Bridging Headers
Faster Mix-and-Match Builds with Precompiled Bridging Headers An examination of build times of Xcode projects that mix Objective-C and Swift, which can contain large bridging headers, shows that the Swift compiler spends a lot of time re-processing the same bridging headers for all the Swift files in a project. In certain projects, each additional Swift file increases the overall build time notice
Swift.org - Swift Server Work Group (SSWG)
The Swift Server work group is a steering team that promotes the use of Swift for developing and deploying server applications. The Swift Server work group will: Define and prioritize efforts that address the needs of the Swift server community Define and run an incubation process for these efforts to reduce duplication of effort, increase compatibility and promote best practices Channel feedback
It's Coming: the Great Swift API Transformation
Cocoa, the Swift standard library, maybe even your own types and methods—it’s all about to change, and you can help determine how. Ever since before Swift was released, there’s been a style gap between Cocoa interfaces and APIs in the Swift standard library; lots of things just look different, often needlessly so. This is no mere aesthetic concern; non-uniformity and lack of predictability make ev
Swift 2.2 Release Process
Ted Kremenek is a member of the Swift Core Team and manages the Languages and Runtimes group at Apple. This post describes the goals, release process, and estimated schedule for Swift 2.2. Swift 2.2 is the first offical release of Swift after Swift was released as open source. It will be a mostly source-compatible release with Swift 2.1, containing a large number of core improvements (e.g., bug fi
