Adding AppDelegate to your SwiftUI App

Hello Swift developers around the globe. In Today’s topic we will tackle Adding the old friend AppDelegate to your shiny new project in SwiftUI.

Once you create a new project in Xcode with SwiftUI you will notice something that there is no AppDelegate file. It must be a heartbreaking for some of you, and for that reason this article will help you out linking an AppDelegate class to your SwiftUI app.

First Step:

Create an Xcode project. -> Choose App -> Make sure to select SwiftUI in Interface option.

Click Next and you will get this:

No App Delegate so far, and that brings us to step two.

Second Step:

Create a new file in your Project folder and name it AppDelegate

Now Copy -> Paste this code in your newly created file “AppDelegate”

import Foundation
import SwiftUI

class AppDelegate: NSObject, UIApplicationDelegate {
    
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
       
        return true
    }
    
    //YOU CAN ADD OTHER UIApplicationDelegate here
    
}

That brings us to our last step

Third and Final Step:

Open you main app SwiftUI file in our example here it’s “AppDelegateSampleApp”:

Copy this line of code and paste as same as in the screenshot in your Main SwiftUI App file:

@UIApplicationDelegateAdaptor(AppDelegate.self) private var appDelegate

That’t it! Easy right?
