WKWebview Prevent updateUIView - ios

Question

When creating the WKWebView I pass the web page URL via #Binding webPageURL.
I also update the displayed website via webPageURL.
The problem here is that when I call a NavigationLink and navigate back from the NavigationLink, the updateUIView method is called and the WKWebView reloads the web page.
How do I prevent the WKWebView from calling the method updateUIView when I navigate back from the NavigationLink?
struct MainView:View {
#State private var isActive = false
#Binding var stateWebPageURL:String
var body: some View {
return VStack {
MyWKWebView(webPageURL:$stateWebPageURL)
NavigationLink(destination: SecoundDestination(),isActive: $isActive) {
Text("Do Something")
}
}
}
}
struct MyWKWebView: UIViewRepresentable {
#Binding var webPageURL:String
func updateUIView(_ uiView: WKWebView, context: Context) {
let pageURL = URL(string:webPageURL)
let urlRequest = URLRequest(url: pageURL!)
uiView.load(urlRequest)
}
func makeUIView(context: Context) -> WKWebView {
let webView = WKWebView(frame: .zero,configuration: webConfiguration)
let pageURL = URL(string:webPageURL)
let urlRequest = URLRequest(url: pageURL!)
webView.load(urlRequest)
return webView
}
func makeCoordinator() -> ContentController {
ContentController()
}
}

Provided code is not testable, so just by code reading, the idea is to make explicitly MyWKWebView equatable, as below
var body: some View {
return VStack {
MyWKWebView(webPageURL:$stateWebPageURL).equatable() // << here !!
and
struct MyWKWebView: UIViewRepresentable, Equatable {
static func == (lhs: MyWKWebView, rhs: MyWKWebView) -> Bool {
lhs.webPageURL == rhs.webPageURL
}
// ... other your code
SwiftUI should not update equal views, so should work.
