To integrate Alamofire into your Xcode project using CocoaPods, specify it in your `Podfile`: + +```ruby +pod 'Alamofire', '~> 5.2' +``` + +### Carthage + +[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate Alamofire into your Xcode project using Carthage, specify it in your `Cartfile`: + +```ogdl +github "Alamofire/Alamofire" ~> 5.2 +``` + +### Swift Package Manager + +The [Swift Package Manager](https://swift.org/package-manager/) is a tool for automating the distribution of Swift code and is integrated into the `swift` compiler. It is in early development, but Alamofire does support its use on supported platforms. + +Once you have your Swift package set up, adding Alamofire as a dependency is as easy as adding it to the `dependencies` value of your `Package.swift`. + +```swift +dependencies: [ + .package(url: "https://github.com/Alamofire/Alamofire.git", .upToNextMajor(from: "5.2.0")) +] +``` + +### Manually + +If you prefer not to use any of the aforementioned dependency managers, you can integrate Alamofire into your project manually. + +#### Embedded Framework + +- Open up Terminal, `cd` into your top-level project directory, and run the following command "if" your project is not initialized as a git repository: + + ```bash + $ git init + ``` + +- Add Alamofire as a git [submodule](https://git-scm.com/docs/git-submodule) by running the following command: + + ```bash + $ git submodule add https://github.com/Alamofire/Alamofire.git + ``` + +- Open the new `Alamofire` folder, and drag the `Alamofire.xcodeproj` into the Project Navigator of your application's Xcode project. + + > It should appear nested underneath your application's blue project icon.
