UIAlertView is deprecated and unavailable for UIScene based applications, please use UIAlertController

Question

I'm new to Swift and I'm getting this Error.

I don't get it because I don't use any type of alert in my code.

Here is my ViewController:

import UIKit
import WebKit

class ViewController: UIViewController{

    @IBOutlet weak var webView: WKWebView!
    override func viewDidLoad() {
        super.viewDidLoad()

        let url = URL(string: "https://www.google.com/maps")!
        webView.load(URLRequest(url: url))
    }
}

I only want to use WKWebView in my app and use the location.

I already added NSLocationAlwaysAndWhenInUseUsageDescription to the info.plist

You can reproduce this error if you using iOS 13, Xcode and this example and any website which uses the location like google maps.

Which line of code exactly is causing that error? Are you getting the error at compile time or at runtime? — rmaddy, Oct 01 '19 at 15:34
@Sh_Khan I wanted to show that I'm not using a type of alert — Soteri, Oct 01 '19 at 15:38
What code is your app running at the time the message appears in the console? — rmaddy, Oct 01 '19 at 15:39
Looks like this is a [duplicate](https://stackoverflow.com/questions/32690086/uialertview-first-deprecated-ios-9/34151288). UIAlertView is no longer used. Scroll down for the swift answer. — HJDavies, Oct 01 '19 at 15:43
@HJDavies no because I'm not using an alert so I can't cange it to the new one... — Soteri, Oct 01 '19 at 15:49
@rmaddy the app crashes everytime I want to get the location. Like opening google maps in the WKWebView and clicking the get position button — Soteri, Oct 01 '19 at 15:53
Other than the message, is your app working and are you able to get the location? — rmaddy, Oct 01 '19 at 15:57
@rmaddy what do you mean? Because I only ask for the question over this website which hasn't anything to do with this app — Soteri, Oct 01 '19 at 15:59

I was also going through the same issue, i'm able to solve it getting help from a developer, scene base application that is new yet not support ui alert view so it crashes the app, we can remove the scene base application we can use window base app, follow these steps to resolve the issue:

First remove the SceneDelegate file check this image for first step Second remove UISceneSession Lifecycle two methods from AppDelegate file check this image for second step Third go to your info plist and remove Application Scene Manifest Entry from it check this image for third step Go ahead and build the project, run it now, make sure you have window property in AppDelegate

Thanks Faisal, you helped me out with this. For anyone unsure on what Faisal meant with his last statement "**make sure you have window property in AppDelegate**"... `var window : UIWindow?;` Should be added to the **AppDelegate** class declaration – KingRidgehead Feb 03 '20 at 14:03
Great ! Thank you – Khaled Shoushara Jun 09 '20 at 09:03
For Objective-c : @property (strong, nonatomic) UIWindow *window; – user3198930 Sep 26 '21 at 22:28
