Loader image before webView finish loading Swift 5 - swift

Question

I have simple webview.
All I need is the image to disappear after webView finish loading.
This function work, but I get error on line "imageView.isHidden = false"
error is : " Use of unresolved identifier 'imageView' "
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
imageView.isHidden = false
}
Full code:
import UIKit
import WebKit
class ViewController: UIViewController, WKUIDelegate, WKNavigationDelegate {
var webView: WKWebView!
public var screenWidth: CGFloat {
return UIScreen.main.bounds.width
}
public var screenHeight: CGFloat {
return UIScreen.main.bounds.height
}
override func loadView() {
let webConfiguration = WKWebViewConfiguration()
webView = WKWebView(frame: .zero, configuration: webConfiguration)
webView.uiDelegate = self
webView.navigationDelegate = self
view = webView
}
override func viewDidLoad() {
super.viewDidLoad()
let imageName = "icon.png"
let image = UIImage(named: imageName)
let imageView = UIImageView(image: image!)
imageView.frame = CGRect(x: 0, y: 0, width: screenWidth, height:screenHeight)
view.addSubview(imageView)
let myURL = URL(string:"https://google.com")
let myRequest = URLRequest(url: myURL!)
webView.load(myRequest)
}
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
imageView.isHidden = false
}
}

Answer 1

You need to assign it to an instance property (like you already did for var webView: WKWebView!) and assign it - then you have access to it at a later point in time.
self.imageView = UIImageView(image: image!)

Answer 2

import UIKit
import WebKit
class ViewController: UIViewController, WKUIDelegate, WKNavigationDelegate {
var webView: WKWebView!
var imageView: UIImageView!
public var screenWidth: CGFloat {
return UIScreen.main.bounds.width
}
public var screenHeight: CGFloat {
return UIScreen.main.bounds.height
}
override func loadView() {
let webConfiguration = WKWebViewConfiguration()
webView = WKWebView(frame: .zero, configuration: webConfiguration)
webView.uiDelegate = self
webView.navigationDelegate = self
view = webView
}
override func viewDidLoad() {
super.viewDidLoad()
let imageName = "icon.png"
let image = UIImage(named: imageName)
imageView = UIImageView(image: image!)
imageView.frame = CGRect(x: 0, y: 0, width: screenWidth, height:screenHeight)
view.addSubview(imageView)
let myURL = URL(string:"https://google.com")
let myRequest = URLRequest(url: myURL!)
webView.load(myRequest)
}
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
imageView.isHidden = false
}
}
try this
