SPM으로 바이너리 패키징하기

// 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")

// Sources/App/main.swift (example content)
let args = CommandLine.arguments.dropFirst()
if args.contains("--help") {

} else if let name = args.first {
    print("Hello, \\(name)!")
} else {
    print("Hello from app 1.0.0")

// 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)

// 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
