添加依赖项{#add-dependencies}

项目通常依赖第三方库来提供额外功能。为此，请运行以下命令，以获得最佳的项目编辑体验：

bash

tuist edit

将打开一个包含项目文件的 Xcode 项目。编辑Package.swift 并添加

swift

// swift-tools-version: 5.9
import PackageDescription

#if TUIST
    import ProjectDescription

    let packageSettings = PackageSettings(
        // Customize the product types for specific package product
        // Default is .staticFramework
        // productTypes: ["Alamofire": .framework,]
        productTypes: [:]
    )
#endif

let package = Package(
    name: "MyApp",
    dependencies: [
        // Add your own dependencies here:
        // .package(url: "https://github.com/Alamofire/Alamofire", from: "5.0.0"),
        // You can read more about dependencies here: https://docs.tuist.io/documentation/tuist/dependencies
        .package(url: "https://github.com/onevcat/Kingfisher", .upToNextMajor(from: "7.12.0")) // [!code ++]
    ]
)

然后编辑项目中的应用程序目标，将Kingfisher 声明为依赖关系：

swift

import ProjectDescription

let project = Project(
    name: "MyApp",
    targets: [
        .target(
            name: "MyApp",
            destinations: .iOS,
            product: .app,
            bundleId: "dev.tuist.MyApp",
            infoPlist: .extendingDefault(
                with: [
                    "UILaunchStoryboardName": "LaunchScreen.storyboard",
                ]
            ),
            buildableFolders: [
                "MyApp/Sources",
                "MyApp/Resources",
            ],
            dependencies: [
                .external(name: "Kingfisher") // [!code ++]
            ]
        ),
        .target(
            name: "MyAppTests",
            destinations: .iOS,
            product: .unitTests,
            bundleId: "dev.tuist.MyAppTests",
            infoPlist: .default,
            sources: ["MyApp/Tests/**"],
            resources: [],
            dependencies: [.target(name: "MyApp")]
        ),
    ]
)

然后运行tuist install ，使用Swift 软件包管理器解析并提取依赖项。

Spm As A Dependency Resolver

Tuist 推荐的依赖关系处理方法仅使用 Swift 包管理器 (SPM) 来解决依赖关系。然后，Tuist 将它们转换为 Xcode 项目和目标，以实现最大程度的可配置性和可控性。

项目可视化{#visualize-the-project}#

您可以通过运行

bash

tuist graph

该命令将输出并打开项目目录下的graph.png 文件：

项目图 !

使用依赖关系{#use-the-dependency}#

运行tuist generate 在 Xcode 中打开项目，并对ContentView.swift 文件进行以下修改：

swift

import SwiftUI
import Kingfisher // [!code ++]

public struct ContentView: View {
    public init() {}

    public var body: some View {
        Text("Hello, World!") // [!code --]
            .padding() // [!code --]
        KFImage(URL(string: "https://cloud.tuist.io/images/[email protected]")!) // [!code ++]
    }
}


struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

在 Xcode 中运行应用程序，您应该会看到从 URL 加载的图像。
