Swiftcompatible

Swiftcompatible is a designation for software libraries, frameworks, tools, and modules that conform to a defined set of interoperability criteria with the Swift programming language and its runtime. The designation aims to help developers identify components that can be consumed by Swift projects with predictable behavior and minimal integration effort.

The scope includes native Swift code libraries, Swift bindings for other languages, and bridging layers that allow interoperation with C, Objective-C, C++, Python, and JavaScript, as well as packaging compatibility with Swift Package Manager and Xcode build environments. The label does not guarantee performance; it focuses on API stability, correctness, and proper error handling.

Criteria for Swiftcompatible components include public API stability across releases, adherence to Swift naming and API conventions, correct use of Swift error handling, availability of module interfaces, and, where applicable, a stable ABI. It also covers cross-platform compatibility across platforms supported by Swift, such as iOS, macOS, and Linux. Packaging metadata and build configuration should align with common Swift tooling expectations.

Certification is overseen by a community governance body that maintains the standard and provides a certification workflow. Projects can submit their components for testing, and passing submissions may receive the Swiftcompatible badge in metadata and documentation. The process is voluntary and repeatable, and certifications may be refreshed as languages and ecosystems evolve.

History and impact: The concept emerged from community discussions in the mid-2020s to improve component discoverability and reduce integration friction in Swift projects. Proponents argue that the label aids developers in choosing dependable Swift-ready components, while critics caution that certification cannot cover all edge cases and should complement, not replace, testing and code review.
