I have an issue with WKWebview. The pages load without any problems, but whenever I tap on any button on website, slide photos or accept cookies policy I get the following error:

2019-10-14 11:27:02.933458+0200 AppTitle[2592:447958] [general] Connection to daemon was invalidated

Does anyone know what may be the issue or what am I missing? This error causes further problems inside the app. Here is my code:

import UIKit
import WebKit
import TinyConstraints
class DetailsVC: UIViewController, WKNavigationDelegate, WKUIDelegate {
let myUrl = URL(string: "https://google.pl/")
var webView: WKWebView = {
  let webview = WKWebView()
  return webview
}()
func addWebView() {
  view.addSubview(webView)
  webView.edgesToSuperview(insets: .top(40) + .right(0) + .left(0), usingSafeArea: true)
  webView.navigationDelegate = self
  webView.uiDelegate = self
  webView.load(URLRequest(url: self.myUrl!))
}
override func viewDidLoad() {
  super.viewDidLoad()
  // Add webview
  addWebView()
  }
}

I have the same or a very similar issue on an Objective C codebase. I suspect that after the error message appears, input events to the associated UIView are being dropped. Were you able to identify a root cause or a workaround?

proposes an explanation (could not check) to the loss of connection:

The ‘processAssertionWasInvalidated’ comes after the ‘WKWebView’ object is released from memory. Retaining a reference (for example, by reusing the view controller that contains it instead of creating a new one) avoids this warning. Apparently something is trying to communicate with web view and has not been told it has been released.
