How to open to a specific view using home quick actions


I am new to Swift and have been using SwiftUI, not Storyboard.

I set the UIApplicationShortcutItems in the Info.plist and have two quick actions that are able to present an alert with launchOptions.

I am able to switch-case out the quick actions in SceneDelegate.swift

func windowScene(_ windowScene: UIWindowScene, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: @escaping (Bool) -> Void) {
    switch shortcutItem.type {
    case "QuickAction1":
        OneView() // What do I do to open this SwiftUI struct View?
        break
    case "QuickAction2":
        SecondView() // What do I do to open this SwiftUI struct View?
        break
    default:
        break
    }
}

What is the proper way to open a particular view from a home quick action using SwiftUI?


ContentView.swift

struct ContentView: View {
    var body: some View {
        NavigationView {
            VStack {
                NavigationLink(destination: OneView())
                NavigationLink(destination: TwoView())
            }
        }
    }
}

Solution

  • Here is possible approach by steps (tested with Xcode 11.2 / iOS 13.2)

    1. Add AppSettings class to store mode of views to be presented by shorcut
        class AppSettings: ObservableObject {
            enum Mode {
                case one
                case two
            }
            @Published var mode: Mode? = nil
        }
    
    1. make appSettings scene delegate member to access it and in ContentView and in shortcut delegate and pass it in ContentView as environment object
        let appSettings = AppSettings()
        
        func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        
            let contentView = ContentView().environmentObject(appSettings)
            // ...
    
    1. activate corresponding mode in shortcut scene delegate
        func windowScene(_ windowScene: UIWindowScene, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: @escaping (Bool) -> Void) {
            switch shortcutItem.type {
            case "QuickAction1":
                appSettings.mode = .one
                break
            case "QuickAction2":
                appSettings.mode = .two
                break
            default:
                break
            }
            // ...
        }
    
    1. Make ContentView present links conditionally based on selected shortcut mode
        struct ContentView: View {
            @EnvironmentObject var appSettings: AppSettings
            
            var body: some View {
                NavigationView {
                    VStack {
                        NavigationLink(destination: OneView(),
                                       tag: AppSettings.Mode.one,
                                       selection: $appSettings.mode)
                            { Text("To One") }
                        NavigationLink(destination: TwoView(),
                                        tag: AppSettings.Mode.two,
                                        selection: $appSettings.mode)
                            { Text("To Two") }
                    }
                }
            }
        }
