# Swift Tooling Implementation

## Package.swift Structure

```swift
// swift-tools-version: 5.9
import PackageDescription

let package = Package(
    name: "MyNetworkLibrary",
    platforms: [.iOS(.v15), .macOS(.v12)],
    products: [
        .library(name: "MyNetworkLibrary", targets: ["MyNetworkLibrary"]),
    ],
    dependencies: [
        .package(url: "https://github.com/Alamofire/Alamofire.git", .upToNextMajor(from: "5.0.0"))
    ],
    targets: [
        .target(
            name: "MyNetworkLibrary",
            dependencies: ["Alamofire"]
        ),
        .testTarget(
            name: "MyNetworkLibraryTests",
            dependencies: ["MyNetworkLibrary"]
        ),
    ]
)
```

## SwiftLint Config (.swiftlint.yml)

```yaml
disabled_rules:
  - trailing_whitespace
opt_in_rules:
  - empty_count
  - force_unwrapping
  - vertical_whitespace_closing_braces

line_length: 80
identifier_name:
  min_length: 3
  max_length: 40
```

## Environment Specific Code

```swift
func getBaseURL() -> String {
    #if DEBUG
    return "https://staging-api.example.com"
    #else
    return "https://api.example.com"
    #endif
}
```

## Package.swift with Composable Architecture

```swift
// Package.swift
let package = Package(
    name: "MyFeature",
    platforms: [.iOS(.v16)],
    products: [
        .library(name: "MyFeature", targets: ["MyFeature"]),
    ],
    dependencies: [
        .package(url: "https://github.com/pointfreeco/swift-composable-architecture", from: "1.0.0"),
    ],
    targets: [
        .target(name: "MyFeature", dependencies: [
            .product(name: "ComposableArchitecture", package: "swift-composable-architecture"),
        ]),
        .testTarget(name: "MyFeatureTests", dependencies: ["MyFeature"]),
    ]
)
```
