Type of expression is ambiguous without more context swift4

I am getting error as:

"Type of expression is ambiguous without more context swift4"

I am making local notification reminder page for iPhone app. I am using Xcode 9 and Swift 4.

import UIKit
@UIApplicationMain

class AppDelegate: UIResponder, UIApplicationDelegate 
{
    var window: UIWindow?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {
        // Override point for customization after application launch.

        if(UIApplication.instancesRespond(to: Selector("registerUserNotificationSettings:"))) {
            UIApplication.sharedApplication.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: .Alert | .Badge, categories: nil))
        }

        return true
    }

    func application(_ application: UIApplication, didReceive notification: UILocalNotification) {
        application.applicationIconBadgeNumber = 0
    }

The issue you are facing is because the syntax of code is not correct. The code you posted here is in Swift-2 which is why it is giving you syntax error.

Use the below code in Swift-4:

UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings.init(types: [.alert, .badge], categories: nil))

Let me know if you still face any issues.
