Maui iOS WebView - MauiWKWebView DidFinishNavigation not called.

[RobFrancisAu]

Description

Hey all,

It appears that DidFinishNavigation is not being called in MauiWKWebView.

maui/src/Core/src/Platform/iOS/MauiWKWebView.cs

Line 79 in 7773f90

[Export("webView:didFinishNavigation:")]

From what I can gather the NavigationDelegate is set in the constructor of MauiWKWebView as a MauiWebViewNavigationDelegate.

maui/src/Core/src/Platform/iOS/MauiWKWebView.cs

Line 41 in 7773f90

NavigationDelegate = new MauiWebViewNavigationDelegate(handler);

This MauiWebViewNavigationDelegate is what actually contains the implementation for DidFinishNavigation

maui/src/Core/src/Platform/iOS/MauiWebViewNavigationDelegate.cs

Line 25 in 7773f90

[Export("webView:didFinishNavigation:")]

As a result of this, when navigating in a webview on iOS the line await handler.ProcessNavigatedAsync(url); in the MauiWKWebView

maui/src/Core/src/Platform/iOS/MauiWKWebView.cs

Line 88 in 7773f90

await handler.ProcessNavigatedAsync(url);

is not called. This is responsible for syncing cookies.

maui/src/Core/src/Handlers/WebView/WebViewHandler.iOS.cs

Line 134 in 7773f90

await SyncPlatformCookiesToVirtualViewAsync(url);

.

Steps to Reproduce

1. Put a breakpoint on

   maui/src/Core/src/Platform/iOS/MauiWKWebView.cs

   Line 82 in 7773f90

   var url = CurrentUrl;

2. Put a breakpoint on
   

   maui/src/Core/src/Platform/iOS/MauiWebViewNavigationDelegate.cs

   Line 28 in 7773f90

   var handler = Handler;

When navigating inside a webview on iOS I was unable to hit breakpoint 1. Breakpoint 2 hit each time.

Going through the history here, if I understand it right, I believe the Navigation Delegate was added a week or so after the cookie code was added. So that code would have been working for about a week in Main.
