Swift Playground and Toolchain

Swift code can be run in Xcode Playgrounds for rapid prototyping, or compiled into full applications. The Swift compiler (swiftc) is also available from the command line. The Swift Package Manager (SPM) handles dependencies and project structure for server-side or cross-platform Swift projects. Package.swift defines targets and dependencies. Xcode is the primary IDE for Apple platform development, providing a simulator, debugger, Interface Builder, and the full SDK.

Example

// Swift Package Manager - Package.swift
// swift-tools-version: 5.9
import PackageDescription

let package = Package(
    name: "MyApp",
    dependencies: [
        .package(url: "https://github.com/apple/swift-argument-parser", from: "1.0.0"),
    ],
    targets: [
        .executableTarget(
            name: "MyApp",
            dependencies: [
                .product(name: "ArgumentParser", package: "swift-argument-parser"),
            ]
        ),
        .testTarget(
            name: "MyAppTests",
            dependencies: ["MyApp"]
        ),
    ]
)
