Could you eliminate string allocation and comparison by using direct type checking?

if (webView.Source is HtmlWebViewSource)

[devanathan-vaithiyanathan]

@jsuarezruiz, We can't check the type directly because HtmlWebViewSource belongs to the Controls project, whereas the Extensions are defined in the Core project. So accessed the type using GetType().Name.

Pull Request Overview

This PR fixes an issue where WebView.Reload() with HtmlWebViewSource returns WebNavigationResult.Failure in the Navigated event on iOS, caused by WKWebView not properly supporting the .reload() method for HTML strings loaded via LoadHtmlString.

Key Changes:

• Modified the reload logic to detect HtmlWebViewSource and reload from the source instead of using WKWebView's native reload method
• Added comprehensive UI tests to verify the fix works correctly

Reviewed Changes

File	Description
src/Core/src/Platform/iOS/WebViewExtensions.cs	Enhanced UpdateReload method to handle HtmlWebViewSource by reloading from source instead of using native WKWebView reload
src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue30515.cs	Added NUnit test to verify WebView HTML source reload returns Success status
src/Controls/tests/TestCases.HostApp/Issues/Issue30515.cs	Created UI test page with WebView using HtmlWebViewSource and reload functionality for testing

[Copilot]

Using string comparison with type name is fragile and could break if the type is renamed or if there are similar named types. Consider using is HtmlWebViewSource pattern matching or webView.Source is HtmlWebViewSource for type checking instead.

Suggested change

	var sourceType = webView.Source.GetType().Name;
	if (string.Equals(sourceType, "HtmlWebViewSource", StringComparison.Ordinal))
	if (webView.Source is HtmlWebViewSource)

[Copilot]

The cast platformWebView is IWebViewDelegate seems incorrect since platformWebView is of type WKWebView, not an IWebViewDelegate. This cast will likely always fail. You should either get the delegate from the WebView handler or use a different approach to access the Load method.

📋 Pre-Flight — Context & Validation

Issue: #30515 - [iOS] WebView.Reload() with HtmlWebViewSource returns WebNavigationResult.Failure in Navigated event
PR: #30625 - [iOS] Fix WebView.Reload() with HtmlWebViewSource returns WebNavigationResult.Failure in Navigated event
Platforms Affected: iOS (file also compiles for MacCatalyst)
Files Changed: 1 implementation, 2 test

Key Findings

• The issue repro calls WebView.Reload() on an HtmlWebViewSource; iOS reports WebNavigationResult.Failure from Navigated instead of Success.
• The PR changes src/Core/src/Platform/iOS/WebViewExtensions.cs so UpdateReload detects HtmlWebViewSource by type name and calls webView.Source.Load(webViewDelegate) instead of native WKWebView.Reload().
• Regression coverage added a WebView UI test under Issue30515 with category WebView.
• Gate result supplied by caller: ✅ PASSED — tests fail without fix and pass with the PR fix. Gate was not re-run.
• Independent code review found unresolved correctness concerns around navigation event semantics, stale webView.Source after in-WebView navigation, and fragile type-name detection.

Code Review Summary

Verdict: NEEDS_CHANGES
Confidence: medium
Errors: 3 | Warnings: 1 | Suggestions: 1

Key code review findings:

• ✗ src/Core/src/Platform/iOS/WebViewExtensions.cs:73 — reloading HTML through Source.Load() can report WebNavigationEvent.NewPage rather than Refresh because LoadHtmlString reaches the delegate as WKNavigationType.Other.
• ✗ src/Core/src/Platform/iOS/WebViewExtensions.cs:65-81 — webView.Source remains the original configured source after the user navigates via a link, so Reload() can discard the current URL page and re-render the original HTML.
• ✗ src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue30515.cs:21 — the test reads the status immediately after tapping reload; the supplied gate result says gate passed, but the review still recommends waiting for the navigated status deterministically.
• ⚠ src/Core/src/Platform/iOS/WebViewExtensions.cs:69 — GetType().Name == "HtmlWebViewSource" misses subclasses and is brittle/trimming-unfriendly.
• ℹ A delegate-polymorphic or platform-view state approach can remove the type-name check, but each has tradeoffs documented in try-fix attempts.

🔬 Code Review — Deep Analysis

Code Review — PR #30625

Independent Assessment

What this changes: iOS UpdateReload() no longer blindly calls WKWebView.Reload(). It checks whether the virtual WebView has a source and whether the platform view implements IWebViewDelegate; if the source type name equals HtmlWebViewSource, it reloads by calling webView.Source.Load(webViewDelegate), otherwise it uses native reload.

Inferred motivation: WKWebView.Reload() does not reliably reload content originally loaded with LoadHtmlString, so the PR tries to re-render the configured HTML source and make Navigated report success.

Reconciliation with PR Narrative

Author claims: The PR fixes WebView.Reload() for HtmlWebViewSource on iOS so the Navigated event reports success.
Agreement/disagreement: The supplied gate result indicates the PR fix passes the regression gate. Code review still found correctness concerns with event classification, stale source behavior after link navigation, and brittle source detection.

Prior Review Reconciliation

Prior ❌ Error Finding	Source	Status	Evidence
HTML source reload can discard the current page after user navigates away via an in-WebView link.	Independent code review / expert review	❌ Unresolved	Current PR still branches from webView.Source, which remains the original configured source.
HTML reload through LoadHtmlString can report NewPage instead of Refresh.	Independent code review / expert review	❌ Unresolved	MauiWebViewNavigationDelegate.DecidePolicy maps WKNavigationType.Other to NewPage.
Type-name check is fragile for subclasses.	Independent code review / expert review	❌ Unresolved	Current PR uses webView.Source.GetType().Name == "HtmlWebViewSource".

Blast Radius Assessment

• Runs for all instances: No — only explicit WebView.Reload() calls on iOS/MacCatalyst.
• Startup impact: No.
• Static/shared state: No new static state in the PR fix.

CI Status

• Required-check result: undetermined locally; gh is unauthenticated in this environment.
• Classification: Gate result was supplied by caller as ✅ PASSED; CI status was not re-queried.
• Action taken: Did not rerun gate per instructions; confidence capped by platform-specific code and local CI/tooling limitations.

Findings

❌ Error — HTML reload can report NewPage instead of Refresh

src/Core/src/Platform/iOS/WebViewExtensions.cs:73 calls webView.Source.Load(webViewDelegate). For HtmlWebViewSource, this reaches MauiWKWebView.LoadHtml() and LoadHtmlString(). The iOS navigation delegate maps WKNavigationType.Other to WebNavigationEvent.NewPage, so consumers expecting Refresh on reload can observe the wrong navigation event.

❌ Error — Reload after in-WebView link navigation can discard the current page

src/Core/src/Platform/iOS/WebViewExtensions.cs:65-81 decides from webView.Source, but webView.Source is the configured source and is not updated when a user clicks a link inside the WebView. If the user navigates from the original HTML to https://... and then calls Reload(), the PR can re-render the original HTML instead of refreshing the current URL.

❌ Error — Test should wait for the async navigation result

src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue30515.cs:21 taps and immediately reads the label. Even though the supplied gate result says this test gated the PR successfully, the test should wait until the label reaches the expected navigated result to avoid timing-dependent outcomes.

⚠️ Warning — Type-name string comparison misses subclasses

src/Core/src/Platform/iOS/WebViewExtensions.cs:69 uses GetType().Name. A subclass of HtmlWebViewSource would fall through to native reload and reproduce the original failure.

💡 Suggestion — Prefer dispatch/state over source-name inspection

The alternative attempts explored delegate-polymorphic dispatch, platform-view HTML state, and custom URL scheme loading to remove the string type check.

Failure-Mode Probing

• User navigates from HTML to a URL and calls reload: PR fix can reload original HTML because it uses stale webView.Source.
• webView.Source is null: PR falls back to native reload.
• Custom source/subclass that calls LoadHtml: PR falls back to native reload because the type name is not exactly HtmlWebViewSource.
• Repeated reload taps: PR re-enters LoadHtmlString; no static state accumulation, but event classification remains questionable.

Verdict: NEEDS_CHANGES

Confidence: medium
Summary: The PR fix is targeted and gate-passed per supplied result, but the current implementation still has correctness risks. The best alternative direction is the platform-view state approach, but local executable validation was blocked, so no replacement fix was selected.

Attempt Details

try-fix-1 — Delegate recovery after native reload failure

• Result: ⚠️ Blocked by environment; initial iOS test command failed because MAUI build tasks were not built.
• Learning: Recovery-after-failure preserves native URL reload until WKWebView proves native reload cannot work, but this implementation still uses stale webView.Source and a fragile type-name check.

try-fix-2 — Platform-view HTML reload state

• Result: ⚠️ Blocked by environment.
• Learning: This is the strongest candidate conceptually because it removes source type-name inspection and can avoid stale virtual source decisions if all URL navigation paths clear the HTML state. It requires a careful audit of link, form, target-frame, file, and programmatic URL loads.

try-fix-3 — Reload-specific IWebViewDelegate

• Result: ⚠️ Blocked by environment.
• Learning: Existing source polymorphism can distinguish HTML and URL sources without reflection or string checks, but this still asks the configured virtual source what to reload, so it does not solve reload-after-link navigation.

try-fix-4 — Custom reloadable HTML URL scheme

• Result: ⚠️ Blocked by environment.
• Learning: Making HTML content addressable could let native reload work naturally and preserve Refresh, but the naive implementation regresses BaseUrl/relative resource behavior and needs binding/API validation.

Environment blocker: The first test reached .github/scripts/BuildAndRunHostApp.ps1 -Platform ios -TestFilter "VerifyWebViewHTMLSourceReloadStatus", but HostApp build failed because required MAUI build tasks were not built. The one allowed setup attempt (dotnet build Microsoft.Maui.BuildTasks.slnf --no-restore) failed on macOS due missing net472 reference assemblies and missing restored assets. Subsequent test runs were skipped as the same environment blocker.

Exhausted: Yes
Selected Fix: PR's fix for now — it is the only fix with a supplied passing gate result. Candidate #2 is the best alternative direction, but none of the alternatives could be executable-validated here or shown demonstrably better than the PR fix.

Recommended title

[iOS] WebView: Reload HtmlWebViewSource content without WKWebView.Reload()

Recommended description

### Issue Details

Reloading an `HtmlWebViewSource` on iOS causes the `Navigated` event to return `WebNavigationResult.Failure` because `WKWebView.Reload()` does not support reloading content originally loaded from an HTML string.

### Description of Change

Updated the iOS WebView reload path so `WebView.Reload()` detects `HtmlWebViewSource` content and reloads the HTML manually through the existing `IWebViewDelegate` source-loading path instead of calling native `WKWebView.Reload()`.

URL-based WebView sources continue to use the standard native reload path.

### Test Coverage

Added issue regression coverage for #30515:

- `src/Controls/tests/TestCases.HostApp/Issues/Issue30515.cs`
- `src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue30515.cs`

The test verifies that tapping Reload for a WebView backed by `HtmlWebViewSource` reports `Success` through the navigation status UI.

### Issues Fixed

Fixes #30515

- [x] Android
- [x] Windows
- [x] iOS

Candidate details

pr

The PR changes iOS UpdateReload() to detect the concrete HtmlWebViewSource runtime type name and call webView.Source.Load(webViewDelegate) instead of native WKWebView.Reload(). The supplied gate shows the issue test fails without the fix and passes with the fix on iOS.

The expert review still found major correctness gaps: the concrete type-name check misses derived HTML sources, reloading the configured source can reset the WebView back to its original HTML after link navigation, and the UI test does not wait deterministically for reload completion.

pr-plus-reviewer

This sandbox candidate applies expert-review feedback by moving the reload decision toward platform-view state/polymorphic loading, mapping HTML reloads to Refresh, and making the UI test wait for initial and post-reload navigation states. It is more complete than the raw PR on paper, but it was not validated because the instruction explicitly said not to re-run gate verification and the existing try-fix environment had already blocked iOS candidate validation.

Because this candidate adds stateful WebKit behavior, it needs a full navigation-path audit before it can outrank the validated PR: link activation, form submission/resubmission, target-frame manual loads, file loads, programmatic URL loads, back/forward navigation, and failure paths must all clear or preserve HTML reload state correctly.

try-fix-1

This candidate keeps native reload first and recovers in MauiWebViewNavigationDelegate after a failed HTML reload. It was blocked by the local build environment and still has stale-source and type-name issues, so it ranks below the passing PR.

try-fix-2

This candidate tracks the last HTML loaded in MauiWKWebView, reloads from platform-view state, clears state on URL/file navigation, and maps HTML reloads to Refresh. It is the strongest alternative conceptually, but validation was blocked and reviewer findings identified duplicated HTML retention and incomplete state-clearing audit risk.

try-fix-3

This candidate uses a reload-specific IWebViewDelegate to let source polymorphism choose HTML-vs-URL reload behavior. It removes the PR's string comparison but still asks the configured virtual source what to reload, so reload after in-WebView navigation can still replace the current page with the original HTML.

try-fix-4

This candidate serves HTML through a custom maui-html:// URL scheme so native WKWebView.Reload() has a reloadable request. It is a possible long-term architecture, but the current diff drops BaseUrl semantics and needs WebKit binding/API validation.

Winner

Winner: pr

The raw PR fix is the only candidate with supplied fail-without/pass-with-fix regression evidence. The expert review means the PR should not be considered code-review-clean yet, but among the available candidates it is the only empirically validated fix; all alternatives and the reviewer-applied sandbox candidate remain blocked or unvalidated.

Recommended action

Investigate the 9 regressed-vs-base failures: the NavEvents_GoToAsyncAbsoluteRoute_* assertion failures ("Expected: String containing Source=ShellItemChanged") in the Android CoreCLR Navigation leg and the WinUI Controls Shell build error are the highest priority — both legs were green on the most recent base build and are now red. The iOS WebView fix only changes src/Core/src/Platform/iOS/WebViewExtensions.cs, but the shared test files (Issue30515.cs) compile for all platforms and may introduce test-order interference or state leakage in multi-platform legs. Additionally, WebView_SetHtmlSource_VerifyNavigatingEvent, WebView_SetHtmlSource_VerifyNavigatedEvent, and WebView_TestReloadMethod_VerifyReloadFunctionality directly exercise the HtmlWebViewSource navigation path this PR modifies; while ci-scan #36037 documents that leg as recurring on base, their direct overlap with the PR's code path warrants manual confirmation before merge.

Evidence details

PR scope: 3 files changed — src/Core/src/Platform/iOS/WebViewExtensions.cs (iOS-only platform code), src/Controls/tests/TestCases.HostApp/Issues/Issue30515.cs, src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue30515.cs. The platform code change is iOS-only; the test files are shared across all platforms and compile into every platform's test run.

Builds: PR uitests 1482083 · PR devicetests 1482084 · Base uitests 1479246 (06/24/2026, failed/completed) · Base devicetests 1479247 (06/24/2026, failed/completed).

Regressed-vs-base legs (9): macOS UITests ListView, macOS UITests Controls (Page,Performance,Picker,ProgressBar), Android CoreCLR Controls (API 30) Navigation, WinUI UITests Controls Shell, and macOS UITests Controls WebView (from which the WebView timeout cluster and the WinUI build error are extracted). All succeeded on uitests base build 1479246.

NavEvents assertion failures: NavEvents_GoToAsyncAbsoluteRoute_NavigatingEvent_SourceIsShellItemChanged and NavEvents_GoToAsyncAbsoluteRoute_NavigatedEvent_SourceIsShellItemChanged fail with Expected: String containing "Source=ShellItemChanged" in the Android CoreCLR Controls (API 30) Navigation leg — a different platform and area from the iOS WebView fix, but the leg was definitively green on base and is now red on this PR.

WebView test cluster: 14 WebView UI tests in the macOS iOS Mono Controls (vlatest) WebView leg (check) all time out with System.TimeoutException. The leg was absent on the most recent base build, so no leg-level comparison is available; ci-scan #36037 documents this leg pattern as recurring (2/10 base builds). The WebView_SetHtmlSource_* tests directly exercise the navigation-event code path changed by this PR.

Aborted check: macOS UITests Controls Layout (check) was CANCELLED; MemoryLeakB42329 and Issue1939Test (ci-scan #35957, 4/10 base builds) are extracted from this leg.

Device tests: 7 green device-test checks could not have Failed == 0 positively confirmed (no AzDO token; XHarness exits 0 even on device test failure). The failing devicetests check (1482084) shows a Windows build error (PowerShell exited with code '1'); that leg was also red on the base build.

Unmapped check: Build Analysis has no inspectable AzDO build record; review its details URL separately.

Baseline note: The base uitests build 1479246 was failed/completed but no test failures could be extracted from its logs — the uitests baseline is inconclusive. The base devicetests build 1479247 extracted 3 baseline failures; none of the 35 PR failures matched exactly by test+platform.

Limitations: No AzDO token was available; authenticated test-run APIs were skipped. All build metadata, timelines, and logs were queried from the public AzDO REST API.

@kubaflo , I have ensured the failed cases - all tests are passed locally.
The CI failure in CookiesCorrectlyLoadWithMultipleWebViews occurs both with and without this fix. Therefore, it is unrelated to the changes introduced in this PR.
