IOS WKWebview Cache Clearing - ios

Question

I have made a very simple WKWebview IOS app that embeds my Wordpress website ...
import UIKit
import WebKit
class ViewController: UIViewController {
private lazy var url = URL(string: "http://www.myblog.com")!
private weak var webView: WKWebView!
init (url: URL, configuration: WKWebViewConfiguration) {
super.init(nibName: nil, bundle: nil)
self.url = url
navigationItem.title = ""
}
required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) }
override func viewDidLoad() {
super.viewDidLoad()
initWebView()
webView.loadPage(address: url)
}
private func initWebView() {
let webView = WKWebView(frame: .zero, configuration: WKWebViewConfiguration())
view.addSubview(webView)
self.webView = webView
webView.navigationDelegate = self
webView.uiDelegate = self
webView.translatesAutoresizingMaskIntoConstraints = false
webView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor).isActive = true
webView.rightAnchor.constraint(equalTo: view.safeAreaLayoutGuide.rightAnchor).isActive = true
webView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor).isActive = true
webView.leftAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leftAnchor).isActive = true
}
}
extension ViewController: WKNavigationDelegate {
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
guard let host = webView.url?.host else { return }
navigationItem.title = host
}
}
extension ViewController: WKUIDelegate {
func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {
guard navigationAction.targetFrame == nil,
let url = navigationAction.request.url else { return nil }
let vc = ViewController(url: url, configuration: configuration)
if let navigationController = navigationController {
navigationController.pushViewController(vc, animated: false)
return vc.webView
}
present(vc, animated: true, completion: nil)
return nil
}
}
extension WKWebView {
func loadPage(address url: URL) { load(URLRequest(url: url)) }
func loadPage(address urlString: String) {
guard let url = URL(string: urlString) else { return }
loadPage(address: url)
}
}
There is a caching plugin on the actual website and I would like for whenever the app loads on a users device - for the app to pull in a fresh copy of the url. Is this possible?
Can anyone advise where to start or how i can adjust my current code to get started?
Thank you!

Push notifications has nothing to do with the WKWebview.
First you need to handle events in the backend/wordpress. From the mobile side, you need the following:
1- Generating a P12 or P8 certificate and put it on the server to trust APN
2- Register for push notifications in AppDelegate class.
3- Handle receiving a push notification in AppDelegate class too.
