Swift on the server is used for a variety of applications due to its robust features and performance capabilities. Here are some key use cases:

  1. Cloud Services: Swift is used to power many critical features across Apple's cloud services, such as iCloud, Keychain, Photos, and Notes. It is also used in the App Store, processing pipelines, and SharePlay file sharing. Swift's strong typing, optionals, and memory safety make it less prone to crashes and security vulnerabilities, which is crucial for cloud services that handle highly concurrent workloads.

  2. Distributed Systems: Swift's concurrency features allow developers to write scalable and responsive server applications, eliminating common sources of bugs due to data races. This makes it an excellent choice for developing robust and reliable distributed systems.

  3. Private Cloud Compute Services: Apple's new private cloud compute service is built using Swift on the server, handling millions of requests per second.

  4. Networking and Observability: The Swift on Server ecosystem includes libraries for networking, database drivers, observability, message streaming, and more. These libraries help in building comprehensive server applications.

  5. Cross-Platform Development: Swift is supported on Apple platforms, Linux, and Windows, with community efforts extending it to platforms like WebAssembly. This cross-platform capability makes Swift a versatile choice for server-side development.

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.
