Swift empowers you to write advanced code in a concise, readable syntax that even a beginner can understand. Swift supports object-oriented, functional, and generic programming patterns that experienced developers are familiar with. Its progressive disclosure allows you to pick up the language quickly, taking advantage of power-user features as you need them.// Complete implementation of a command line tool@main struct Describe: ParsableCommand {@Argument(help: "The values to describe.")Smallest: \(values.first, default: "No value")Mean: \(total / Double(values.count))### SafeSwift prioritizes safety and eliminates entire classes of bugs and vulnerabilities by its design. Memory safety and data race safety are core features of the language, making them straightforward to integrate into your codebase. Safety is required at compile time, before your applications are ever run.`let transform = Affine2DTransformBuilder()// Call C functions safely with Swift typestransform, rowCount, colCount, v.span, allocator)let uMagnitude = vec_mag(u.span)### InteroperableAdopt Swift in existing code incrementally.Swift provides unmatched interoperability, with its combination of natively understanding C and C++ types without the need for foreign function interfaces, and offering bridging for bi-directional access. Swift’s interoperability features allow you to incrementally adopt the language into existing codebases without requiring a full code rewrite.// Use types from C++, like std::string, directly"apple juice", "grape juice", "green tea"let juices = beverages.filter { cppstring in// and call methods directly on C++ typescppstring.find(.init("juice")) != std.string.npos### AdaptableFrom microcontrollers to servers.Spanning from embedded and kernel to server and apps, Swift excels no matter where it’s used, from constrained environments like firmware, where every byte counts, to cloud services handling billions of requests a day.
