How do I inject dependencies cleanly in SwiftUI with Swift?

Injecting dependencies in SwiftUI can be done cleanly using the Environment and EnvironmentObject features provided by SwiftUI. This allows for a flexible and maintainable architecture, especially when building complex applications. Here’s an example of how to implement dependency injection in SwiftUI.


    struct UserSettings {
        var username: String
    }

    class UserSettingsViewModel: ObservableObject {
        @Published var settings = UserSettings(username: "Guest")
    }

    struct ContentView: View {
        @EnvironmentObject var userSettings: UserSettingsViewModel

        var body: some View {
            VStack {
                Text("Hello, \(userSettings.settings.username)!")
            }
        }
    }

    @main
    struct MyApp: App {
        @StateObject private var userSettings = UserSettingsViewModel()

        var body: some Scene {
            WindowGroup {
                ContentView()
                    .environmentObject(userSettings)
            }
        }
    }
