Note

Are you waiting for the changes in this PR to be merged?
It would be very helpful if you could test the resulting artifacts from this PR and let us know in a comment if this change resolves your issue. Thank you!

Issue Details

• On iOS 26, setting Shell.ForegroundColor (either at the Shell level or Page level) no longer applies the specified color to ToolbarItems.
• The toolbar items remain in the default system tint color instead of respecting the configured foreground color.

Root Cause

• On iOS 26, Apple's LiquidGlass redesign changed how UINavigationBar.TintColor propagates to bar button items — it is no longer automatically inherited.

Description of Change

• Added UpdateRightBarButtonItemTintColors() method in ShellPageRendererTracker.cs to explicitly set the TintColor of right bar button items to the Shell's foreground color for iOS 26+ and Mac Catalyst 26+. This ensures toolbar items correctly reflect the intended color.
• Updated property change handlers (HandleShellPropertyChanged, OnPagePropertyChanged) to call UpdateRightBarButtonItemTintColors() when relevant properties change, guaranteeing color updates are applied when needed.

Issues Fixed

Fixes #34083

Validated the behaviour in the following platforms

• Windows
• Android
• iOS
• Mac

Pull request overview

This pull request fixes an iOS 26-specific issue where Shell.ForegroundColor is not applied to toolbar items due to Apple's LiquidGlass redesign changes. In iOS 26+, UINavigationBar.TintColor no longer automatically propagates to bar button items, requiring explicit TintColor setting on each item.

Changes:

• Added UpdateRightBarButtonItemTintColors() method to explicitly set TintColor on right bar button items for iOS 26+ and MacCatalyst 26+
• Updated property change handlers (HandleShellPropertyChanged, OnPagePropertyChanged) to call the new method when ForegroundColor changes
• Added UI test (Issue34083) with screenshot verification to validate the fix

• The fix only applies TintColor to right bar button items (toolbar items), but the left bar button item (back button/flyout icon) may also be affected by the iOS 26 LiquidGlass change. The UpdateLeftToolbarItems method creates a UIBarButtonItem at line 575-576, but its TintColor is not explicitly set for iOS 26+.

Consider also updating the left bar button item's TintColor in UpdateLeftToolbarItems when iOS 26+ is detected, similar to how UpdateRightBarButtonItemTintColors handles right bar button items. The left bar button item is set in the callback at lines 575-576, so you would need to apply the TintColor there:

NavigationItem.LeftBarButtonItem =
    new UIBarButtonItem(icon, UIBarButtonItemStyle.Plain, (s, e) => LeftBarButtonItemHandler(ViewController, IsRootPage)) { Enabled = enabled };

// Add for iOS 26+
if (OperatingSystem.IsIOSVersionAtLeast(26) || OperatingSystem.IsMacCatalystVersionAtLeast(26))
{
    var foregroundColor = _context?.Shell?.CurrentPage?.GetValue(Shell.ForegroundColorProperty) ??
                        _context?.Shell?.GetValue(Shell.ForegroundColorProperty);
    if (foregroundColor is Graphics.Color shellForegroundColor)
    {
        NavigationItem.LeftBarButtonItem.TintColor = shellForegroundColor.ToPlatform();
    }
}

						if (image is not FontImageSource fontImageSource || !fontImageSource.IsSet(FontImageSource.SizeProperty))

The version check logic is inverted. The condition !(OperatingSystem.IsIOSVersionAtLeast(26) || OperatingSystem.IsMacCatalystVersionAtLeast(26)) returns early when the version is LESS than 26, meaning the TintColor update only happens on iOS 26+. This is correct based on the PR description.

However, consider using a positive condition for better readability:

if (OperatingSystem.IsIOSVersionAtLeast(26) || OperatingSystem.IsMacCatalystVersionAtLeast(26))
{
    // Update TintColor for iOS 26+ only
    if (NavigationItem?.RightBarButtonItems is not { Length: > 0 } rightItems)
    {
        return;
    }
    // ... rest of the logic
}

This makes it immediately clear that the code executes FOR iOS 26+, not AGAINST it.

Suggested change

	if (!(OperatingSystem.IsIOSVersionAtLeast(26) || OperatingSystem.IsMacCatalystVersionAtLeast(26)))
	{
	return;
	}
	if (NavigationItem?.RightBarButtonItems is not { Length: > 0 } rightItems)
	{
	return;
	}
	var foregroundColor = _context?.Shell?.CurrentPage?.GetValue(Shell.ForegroundColorProperty) ??
	_context?.Shell?.GetValue(Shell.ForegroundColorProperty);
	if (foregroundColor is Graphics.Color shellForegroundColor)
	{
	var platformColor = shellForegroundColor.ToPlatform();
	foreach (var item in rightItems)
	{
	item.TintColor = platformColor;
	if (OperatingSystem.IsIOSVersionAtLeast(26) || OperatingSystem.IsMacCatalystVersionAtLeast(26))
	{
	if (NavigationItem?.RightBarButtonItems is not { Length: > 0 } rightItems)
	{
	return;
	}
	var foregroundColor = _context?.Shell?.CurrentPage?.GetValue(Shell.ForegroundColorProperty) ??
	_context?.Shell?.GetValue(Shell.ForegroundColorProperty);
	if (foregroundColor is Graphics.Color shellForegroundColor)
	{
	var platformColor = shellForegroundColor.ToPlatform();
	foreach (var item in rightItems)
	{
	item.TintColor = platformColor;
	}

The test includes a preprocessor directive TEST_FAILS_ON_ANDROID && TEST_FAILS_ON_WINDOWS which disables the test on Android and Windows. The comment references two separate issues for Android and Windows failures.

However, this test should NOT fail on these platforms - it's testing iOS-specific behavior (the test page is marked PlatformAffected.iOS). The test should simply not run on Android/Windows.

Consider using a cleaner approach:

• Remove the TEST_FAILS_ON_ANDROID && TEST_FAILS_ON_WINDOWS directive entirely
• The test framework should automatically skip tests for platforms not affected based on the PlatformAffected.iOS attribute in the Issue attribute
• If platform-specific test execution is needed, use #if IOS || MACCATALYST instead

Issue: #34083 - [iOS26] Shell.ForegroundColor is not applied to ToolbarItems
PR: #34085 - [iOS/Mac Catalyst 26] Fix Shell.ForegroundColor not applied to ToolbarItems
Author: SyedAbdulAzeemSF4852 (Syncfusion partner contributor)
Platforms Affected: iOS 26, MacCatalyst 26 (iOS/Mac-specific behavior change due to Apple LiquidGlass redesign)
Labels: platform/ios, area-controls-toolbar, version/iOS-26, partner/syncfusion, community

Prior Agent Reviews

Two prior agent reviews were conducted, both with Gate FAILED due to environment limitation: no iOS 26 simulator was available. This review has iOS 26.1 simulators available and can properly verify the fix.

Issue Summary

On iOS 26, Apple's LiquidGlass redesign changed how UINavigationBar.TintColor propagates to bar button it is no longer automatically inherited by UIBarButtonItem instances. As a result, Shell.ForegroundColor set at the Shell or Page level no longer applies to ToolbarItems on iOS 26+. This was validated by Syncfusion/Ahamed-Ali as reproducible on iOS 26 with MAUI 10.0.0 and 10.0.40.items

Fix Description

Added UpdateRightBarButtonItemTintColors() method in ShellPageRendererTracker.cs that:

• Version-guarded to iOS 26+ and MacCatalyst 26+ only
• Explicitly iterates over NavigationItem.RightBarButtonItems and sets TintColor on each item
• Reads ForegroundColor from CurrentPage first, then falls back to Shell level
• Sets TintColor = null (system default) when ForegroundColor is cleared (null reset handled correctly via ternary pattern)
• Called from UpdateToolbarItems(), HandleShellPropertyChanged, and OnPagePropertyChanged

Result PASSED:
Platform: ios (iOS 26.1 - iPhone 17 Pro simulator)
Mode: Full Verification

Test Results

Check	Expected	Actual	Result
Tests WITHOUT fix	FAIL	FAIL
Tests WITH fix	PASS	PASS

Analysis

The Gate verification PASSED on iOS 26.1 (iPhone 17 Pro simulator). Previous reviews failed because no iOS 26 simulator was available. This environment has iOS 26.1 available which correctly exercises the version-guarded fix.

• Tests FAIL without the fix (bug is present): TintColor not applied to toolbar items on iOS 26
• Tests PASS with the fix (bug is fixed): TintColor explicitly set via UpdateRightBarButtonItemTintColors()

Note: Auto-detected fix files included some environment-specific files (ci-copilot.yml, provision.yml, VisualRegressionTester.cs) that are modified locally but not part of this PR's diff. The key fix file ShellPageRendererTracker.cs was correctly reverted and restored for the two-run verification.

Conclusion

Gate PASSED - Tests correctly detect the iOS 26 TintColor regression and validate the fix.

Phase 3: Try-Fix Results

Selected Fix: PR's own UpdateRightBarButtonItemTintColors() approach is the best implementation.

Exhausted: 5 attempts run (1 blocked, 1 pass alternative found but inferior, 2 fail, 1 no-response).Yes

Summary

Attempt	Model	Approach	Result
2	claude-opus-4.6	Rebuild with Inline Tinting PASS (but inferior to PR's fix)
3	gpt-5.2	UIAppearance FAIL (snapshot mismatch)	Proxy
4	gpt-5.3-codex	In-constructor tinting with FAIL (compile error)	rebuild
5	gemini-3-pro-preview	(no response from model)
Cross-Pollination Round: No clearly superior new approaches suggested.

Infrastructure Note

iOS 26 snapshot tests require an iPhone 11 Pro simulator (1124x2286px). The default iOS 26 simulators are iPhone 17 Pro (wrong resolution). A custom simulator was created: xcrun simctl create "iPhone 11 Pro (iOS 26)" com.apple.CoreSimulator.SimDeviceType.iPhone-11-Pro com.apple.CoreSimulator.SimRuntime.iOS-26-0.

Best Alternative: Attempt 2 (Rebuild with Inline Tinting)

Attempt 2 found a passing alternative, but it is inferior to the PR's fix:

Aspect	PR's Fix	Attempt 2
Null reset when ForegroundColor cleared No	Yes
Triggers full toolbar rebuild on change	No (minimal)	Yes (full rebuild)
Code clarity Named method	Inline logic
Design quality Better	Acceptable

Conclusion

The PR's UpdateRightBarButtonItemTintColors() approach is the best implementation among all alternatives tested. The only passing alternative (Attempt 2) lacks null-reset support and triggers unnecessary rebuilds.

Title Assessment

Current: [iOS/Mac Catalyst 26] Fix Shell.ForegroundColor not applied to ToolbarItems

** Platform prefix present, describes the behavior being fixed, concise.Good**

Minor suggestion: standardize casing to [iOS/Mac Catalyst 26] (current uses Mac Catalyst, which is correct).

Description Assessment

** Keep As-Is**Good

The description is well-structured with:

• NOTE block at the top
• Root cause section (LiquidGlass TintColor change)
• Description of change (what UpdateRightBarButtonItemTintColors() does)
• Issues Fixed with link
• Platform validation checkboxes (, )Mac iOS
• Before/After screenshots

Only recommended addition: A "What NOT to do" note that UIAppearance proxy approaches fail for this scenario, to guide future agents.

Code Review Findings

Negated compound condition:

if (!(OperatingSystem.IsIOSVersionAtLeast(26) || OperatingSystem.IsMacCatalystVersionAtLeast(26)))
{
    return;
}

Copilot flagged this. A positive condition is more readable:

if (!OperatingSystem.IsIOSVersionAtLeast(26) && !OperatingSystem.IsMacCatalystVersionAtLeast(26))
{
    return;
}

Both are functionally identical (De Morgan's law). This is a cosmetic preference, not a bug.

Positive Observations

• Correct null foregroundColor resolves from page or shell level (consistent with left bar button logic)handling
• Proper null sets TintColor = null when ForegroundColor is cleared, which is critical for correctnessreset
• Version guard prevents behavior on iOS < 26 where TintColor propagation worked automatically
• Called from all three necessary locations: UpdateToolbarItems(), HandleShellPropertyChanged(), OnPagePropertyChanged()
• #if TEST_FAILS_ON_ANDROID && TEST_FAILS_ON_WINDOWS guard follows established codebase pattern
• Snapshot baselines provided for both iOS (18.x) and iOS 26

Design Comparison

The PR's approach is better than the one alternative that passed testing (Attempt 2):

Aspect	PR's Fix	Best Alternative (Attempt 2)
Null reset when ForegroundColor cleared No	Yes
Unnecessary full toolbar rebuild on color change	No	Yes
Readability Named method	Inline

---

Overall Recommendation

APPROVE

Gate: Tests verified to fail without fix and pass with fix.PASSED

Try-Fix: 5 attempts run across multiple models:

• 1 alternative passed (Attempt 2) but is inferior to the PR's approach
• PR's design is cleaner and more correct (handles null reset, minimal updates)

Code quality: Good. One minor style issue (negated condition) but functionally correct.

Confidence: The fix correctly addresses the iOS 26 LiquidGlass behavior change. The approach is minimal, targeted, and consistent with how left bar button items were previously fixed (PR #32997).HIGH

It would be very helpful if you could test the resulting artifacts from this PR and let us know in a comment if this change resolves your issue. Thank you!

Issue Details

• On iOS 26 / Mac Catalyst 26, setting Shell.ForegroundColor (either at the Shell level or Page level) no longer applies the specified color to ToolbarItems.
• The toolbar items remain in the default system tint color instead of respecting the configured foreground color.

Root Cause

On iOS 26, Apple's LiquidGlass redesign changed how UINavigationBar.TintColor propagates to bar button items — it is no longer automatically inherited by UIBarButtonItems placed in the navigation bar.

Description of Change

• Added UpdateRightBarButtonItemTintColors() in ShellPageRendererTracker.cs to explicitly set TintColor on each right bar button item to the Shell's foreground color when running on iOS 26+ or Mac Catalyst 26+.
• Updated HandleShellPropertyChanged and OnPagePropertyChanged to call UpdateRightBarButtonItemTintColors() when Shell.ForegroundColorProperty changes, ensuring live property updates are applied.
• Updated UpdateToolbarItems() to call UpdateRightBarButtonItemTintColors() after setting right bar button items, ensuring color is applied when toolbar items are first constructed.

🟡 Suggestions

1. PlatformAffected.iOS in HostApp [Issue] attribute should include Mac Catalyst

File: src/Controls/tests/TestCases.HostApp/Issues/Issue34083.cs

Current:

[Issue(IssueTracker.Github, 34083, "Toolbar Items Do Not Reflect Shell ForegroundColor", PlatformAffected.iOS)]

Problem: The fix applies to both iOS 26 and Mac Catalyst 26 (the code uses OperatingSystem.IsIOSVersionAtLeast(26) || OperatingSystem.IsMacCatalystVersionAtLeast(26)), and the PR title includes Mac Catalyst. The [Issue] attribute should reflect both affected platforms.

Suggested fix:

[Issue(IssueTracker.Github, 34083, "Toolbar Items Do Not Reflect Shell ForegroundColor", PlatformAffected.iOS | PlatformAffected.Mac)]

---

2. UpdateRightBarButtonItemTintColors() is not protected virtual

File: src/Controls/src/Core/Compatibility/Handlers/Shell/iOS/ShellPageRendererTracker.cs

Current:

void UpdateRightBarButtonItemTintColors()
{
    // ...
}

Problem: The surrounding methods that call this (HandleShellPropertyChanged, OnPagePropertyChanged, UpdateToolbarItems) are all protected virtual, meaning subclasses can override them. If a subclass overrides UpdateToolbarItems and doesn't call base.UpdateToolbarItems(), the tint colors won't be applied. Additionally, if a subclass needs to customize the tint-color-application behavior, it cannot without overriding the calling methods.

Consideration: This is the same pattern used for UpdateLeftToolbarItems(), which is also private — so this is consistent with existing style. If consistency is the priority, the current approach is acceptable. If extensibility is important, mark it protected virtual.

---

✅ Looks Good

• Version guard is correct: OperatingSystem.IsIOSVersionAtLeast(26) || OperatingSystem.IsMacCatalystVersionAtLeast(26) is the proper API for OS version checks in .NET MAUI.
• Null TintColor handling: When foregroundColor is null (not set), platformColor is null, and setting item.TintColor = null correctly restores the default system tint. This is intentional and correct.
• Property lookup priority: The method checks CurrentPage foreground color first, then falls back to Shell-level, which correctly mirrors how the framework resolves inherited values.
• Call sites are complete: All three relevant entry points call the new method — initial construction (UpdateToolbarItems), Shell-level property change (HandleShellPropertyChanged), and page-level property change (OnPagePropertyChanged).
• Tests provided: UI test with screenshot validation is included for both iOS (regular) and iOS 26 snapshots, and Mac Catalyst. The test is correctly gated with #if TEST_FAILS_ON_ANDROID && TEST_FAILS_ON_WINDOWS.
• No breaking changes: The fix is version-gated to iOS/Mac Catalyst 26+ and has no effect on older OS versions.
