Add dependencies

It's common for projects to depend on third-party libraries to provide additional functionality. To do so, run the following command to have the best experience editing your project:

tuist edit

An Xcode project will open containing your project files. Edit the Package.swift and add the

// 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")) 
    ]
)

Then edit the application target in your project to declare Kingfisher as a dependency:

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") 
            ]
        ),
        .target(
            name: "MyAppTests",
            destinations: .iOS,
            product: .unitTests,
            bundleId: "dev.tuist.MyAppTests",
            infoPlist: .default,
            sources: ["MyApp/Tests/**"],
            resources: [],
            dependencies: [.target(name: "MyApp")]
        ),
    ]
)

Then run tuist install to resolve and pull the dependencies using the Swift Package Manager.

SPM AS A DEPENDENCY RESOLVER

Tuist recommended approach to dependencies uses the Swift Package Manager (SPM) only to resolve dependencies. Tuist then converts them into Xcode projects and targets for maximum configurability and control.

Visualize the project

You can visualize the project structure by running:

tuist graph

The command will output and open a graph.png file in the project's directory:

Use the dependency

Run tuist generate to open the project in Xcode, and make the following changes to the ContentView.swift file:

import SwiftUI
import Kingfisher

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

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


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

Run the app from Xcode, and you should see the image loaded from the URL.
