Apple's language for iOS and macOS
Swift Compiler Online — Run Swift Code in Your Browser
Swift replaced Objective-C as Apple's primary language, with modern safety features (optionals, strong typing) and syntax that's genuinely pleasant to write. Outside of Apple's ecosystem it's less common, but for iOS/macOS work it's the default.
What people use Swift here for
- Practicing Swift syntax without opening Xcode
- Testing optionals or a small algorithm in isolation
- Following a Swift tutorial on a non-Mac device

Code you write here runs on a real, self-hosted Judge0 execution backend — actual Swift compiler or interpreter output, not a simulation. A real swiftc compile runs your code, which is genuinely useful if you're on Linux or Windows and don't have a Mac to install Xcode on.
