Embedded code in my Weather article on Medium

SceneDelegate.swift

import UIKit
import SwiftUI

class SceneDelegate: UIResponder, UIWindowSceneDelegate {

    var window: UIWindow?

    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        // Use a UIHostingController as window root view controller
        let window = UIWindow(frame: UIScreen.main.bounds)
        let cityStore = CityStore()
        window.rootViewController = UIHostingController(rootView: CityListView().environmentObject(cityStore))
        self.window = window
        window.makeKeyAndVisible()
    }

}
