Packaging binaries with SPM
Initialize an executable package, set the product , add dependencies, and produce a release binary from .build/release ready to share.
Packaging binaries with SPM is a free Swift Academy lesson on CoddyKit — lesson 3 of 3. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Swift Academy learning path, one of 3 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Why SwiftPM executables?
SwiftPM can build executables you can ship.
- Init executable package
- Define products and targets
- Add dependencies (semantic versions)
- Build release and find the binary
Init & build basics
Use swift package init --type executable to scaffold. Then swift build and swift run to compile and execute.
// In your terminal (for reference):
// swift package init --type executable
// Files created: Package.swift, Sources/<Target>/main.swift, Tests/
// You can then run:
// swift build
// swift run
print("SPM exec template ready")main.swift shape
Executable targets start at Sources/<Target>/main.swift. Keep CLI output short and clear.
// Sources/App/main.swift (example content)
let args = CommandLine.arguments.dropFirst()
if args.contains("--help") {
print("app 1.0.0\\nUsage: app [--help] [name]")
} else if let name = args.first {
print("Hello, \\(name)!")
} else {
print("Hello from app 1.0.0")
}Package.swift essentials
Package.swift essentials:
- products: .executable(name:targets:)
- targets: source folders and dependencies
- dependencies: external packages (use semantic versions like from: "1.2.0")
Product & deps example
Declare an .executable product and wire target dependencies. Pin external packages with semantic versions for stability.
// Package.swift (illustrative)
// import PackageDescription
// let package = Package(
// name: "App",
// platforms: [.macOS(.v12)],
// products: [
// .executable(name: "app", targets: ["App"]),
// ],
// dependencies: [
// // Example: argument parser (replace with real URL in your project)
// // .package(url: "https://github.com/apple/swift-argument-parser", from: "1.2.0")
// ],
// targets: [
// .executableTarget(
// name: "App",
// dependencies: [
// // .product(name: "ArgumentParser", package: "swift-argument-parser")
// ]
// )
// ]
// )Release build & artifact
Ship the file from .build/release/<product>. Consider stripping symbols and zipping for distribution.
// Produce an optimized binary:
// swift build -c release
// Artifact path:
// .build/release/app (product name)
//
// Optional strip symbols (platform-specific tool) or zip:
// # macOS example (illustrative)
// # strip .build/release/app
// # zip app-macos.zip .build/release/app
print("Release binary lives in .build/release/")Release artifact location
Quick check: Where is the release binary?
Recap
Recap: Init an executable package, define the product in Package.swift, add deps with semantic versions, and ship the binary from .build/release.
