Swift LifeCycleにSwiftUI App指定、Push許可、受信、UIApplicationDelegateAdaptor

2020年11月28日

LifeCycleにSwiftUI App指定時、AppDelegate.swiftはプロジェクトにない。
必要な場合に使用するのがUIApplicationDelegateAdaptor。

Example Push認証、受信

import SwiftUI

@main
struct TimeLimitMusicPlayerApp: App {
    @UIApplicationDelegateAdaptor private var appDelegate: AppDelegate
    
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

class AppDelegate: NSObject, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.

        let center = UNUserNotificationCenter.current()
        center.requestAuthorization(options: [.alert, .sound, .badge]) { granted, error in
            
            if let error = error {
                // Handle the error here.
                print(error)
            }
            if granted == true {
                print("許可")
                center.delegate = self
                center.getNotificationSettings(completionHandler: { setting in
                    print(setting)
                })
            }
            else {
                print("非許可")
            }
        }
        
        return true
    }
}

extension AppDelegate: UNUserNotificationCenterDelegate {
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        print(#function)
    }
}
