Swift is a powerful, flexible, open-source programming language developed and maintained by a global community, with Apple identified as its trademark owner. Designed for speed, expressiveness, and safety, Swift supports development across the software stack, from embedded firmware and command-line tools to mobile apps and cloud services. It compiles directly to native code, offers predictable memory management, and builds memory and data-race safety into the language.

Swift’s concise, readable syntax supports object-oriented, functional, and generic programming, helping developers create clear code while accessing advanced features as needed. Its interoperability with C and C++ also enables teams to adopt Swift incrementally within existing projects, without requiring a complete rewrite. The language is adaptable to constrained devices as well as high-performance servers.

The Swift project provides documentation, installation tools for Linux, macOS, and Windows, community forums, packages, and contribution resources. Developers can use Swift with editors and tools including Xcode, Visual Studio Code, Emacs, Neovim, and Cursor.
