@copilot this fix is confirmed to not work. Can you have a look at the workaround in #32930 (comment) that does work. It looks a bit hacky though, is there a decent way to implement this directly in our codebase? |

Pull request overview
This PR addresses an iOS (iPhone) Shell SearchHandler layout issue where the suggestions list visually detaches from the search bar during the “hide navigation bar” presentation animation, leaving a gap. The fix adjusts UISearchController presentation behavior in the iOS Shell renderer and adds a UI test case to cover the scenario.
Changes:
- Configure the iOS
UISearchControllerto not hide the navigation bar and not obscure the background during search presentation. - Add a new HostApp issue page (Shell + SearchHandler) that reproduces the suggestions-gap scenario.
- Add an iOS UI test that triggers suggestions and validates layout via screenshot.

[major] Test coverage / CI discovery - Wrapping the whole test file in #if IOS makes Android test discovery match zero tests when the gate filters to Issue32930, which is the known gate failure. Keep the fixture/method discoverable and skip/guard the body on non-iOS, or use the test infrastructure's platform filtering so non-iOS discovery does not fail with 0 tests.

Issue: #32930 - [iOS] SearchHandler suggestions list does not follow the search bar upward movement on iPhone, creating a layout gap
PR: #32931 - Fix iOS SearchHandler suggestions list gap on iPhone
Platforms Affected: iOS (reported iPhone-only; iPad and Android reported unaffected)
Files Changed: 1 implementation, 3 test
Key Findings
- Issue reproduces when focusing a Shell
SearchHandleron iPhone: the search bar/nav title animates upward while the suggestions list remains anchored lower, leaving a visible gap. - The PR changes
ShellPageRendererTracker.AttachSearchController()to disableUISearchController.HidesNavigationBarDuringPresentationandObscuresBackgroundDuringPresentationfor all iOS Shell search controllers. - Community feedback says setting
ExtendedLayoutIncludesOpaqueBarsfrom a custom renderer did not resolve the issue; MAUI/SDK layout appears to override that workaround. - The added UI test targets the Shell category and screenshot-verifies the suggestions placement, but the whole fixture is wrapped in
#if IOS, which can break targeted discovery on non-iOS platforms.
Code Review Summary
Verdict: NEEDS_CHANGES
Confidence: high
Errors: 1 | Warnings: 2 | Suggestions: 0
Key code review findings:
- ❌
src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue32930.cs:1— wrapping the entire fixture in#if IOScan make targeted discovery find zero tests on non-iOS instead of a skipped/guarded test. ⚠️ src/Controls/src/Core/Compatibility/Handlers/Shell/iOS/ShellPageRendererTracker.cs:1021-1027— the iPhone-specific fix is applied to all UIKit Shell search controllers, broadening behavior to iPad and possibly MacCatalyst.⚠️ src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue32930.cs:32— immediate screenshot verification may capture UIKit transition state; use a retry timeout.

Code Review — Deep Analysis
Code Review — PR #32931
Independent Assessment
What this changes: Creates a UISearchController with navigation-bar hiding/background obscuring disabled, plus an iOS Shell UI regression test.
Inferred motivation: Avoid the iPhone gap between the Shell search bar and suggestions list when search presentation animates.
Reconciliation with PR Narrative
Author claims: Fixes #32930 by setting HidesNavigationBarDuringPresentation = false and ObscuresBackgroundDuringPresentation = false; adds screenshot UI coverage.
Agreement/disagreement: The implementation matches the claimed fix and issue comments confirm the workaround removes the gap. However, the test structure has a discovery problem, and the fix changes behavior beyond the stated iPhone-only scenario.
Findings
❌ Error — iOS-only preprocessor guard can break targeted test discovery
src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue32930.cs:1
Wrapping the entire NUnit fixture in #if IOS means non-iOS test assemblies contain no Issue32930 test at all. When CI/gate tooling targets this issue test on another platform, discovery can report zero matching tests instead of a platform skip/guard; this is also already reflected in existing review feedback as a known gate failure. Keep the fixture/method discoverable and skip/guard execution on unsupported platforms, or use the UI test infrastructure's platform filtering.
⚠️ Warning — iPhone-specific fix is applied to all UIKit Shell search controllers
src/Controls/src/Core/Compatibility/Handlers/Shell/iOS/ShellPageRendererTracker.cs:944-945
The comments and issue describe an iPhone-only gap, and explicitly say iPad does not have the issue. This code applies the changed UISearchController behavior unconditionally for this iOS Shell path, changing default native search presentation behavior for iPad as well, and potentially MacCatalyst if this compatibility path is shared there. Consider scoping to UIUserInterfaceIdiom.Phone or documenting why the broader behavior change is intended.
⚠️ Warning — screenshot may capture UIKit transition state
src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue32930.cs:32
The test enters text into the native search field and immediately verifies a screenshot after waiting only for "Apple". Because search presentation/layout involves UIKit animation, VerifyScreenshot(retryTimeout: TimeSpan.FromSeconds(...)) would reduce flakiness.
Devil's Advocate
The broad search-controller behavior may be an acceptable product tradeoff: issue comments say the visible gap is fixed and the navigation-bar behavior change "seems work fine." I would not block solely on that. The test discovery issue is concrete and CI-relevant, so it should be fixed before merge. CI currently includes a maui-pr/Build Analysis failure from an integration timeout; deep Shell UI tests are reported passing, but the PR is not fully green.
Verdict: NEEDS_CHANGES
Confidence: high
Summary: The functional fix appears plausible and externally validated, but the added test is conditionally compiled away on non-iOS and can break targeted discovery/gate runs. Address the test discovery issue before merge; consider narrowing or explicitly justifying the broader native search behavior change.
Fix — Analysis & Comparison
Fix Candidates
| # | Source | Approach | Test Result | Files Changed | Notes |
|---|---|---|---|---|---|
| 1 | try-fix | Scope HidesNavigationBarDuringPresentation=false/ObscuresBackgroundDuringPresentation=false to iPhone ShowsResults; fix test discovery/retry. |
❌ FAIL | 2 files | Compile failure: IgnoreIfPlatforms unavailable on _IssuesUITest. |
| 2 | try-fix | Leave search-controller presentation defaults; adjust ShellSearchResultsRenderer top layout/content inset for iPhone results. |
❌ FAIL | 3 files | Build failure: public overrides require PublicAPI entries (RS0016). |
| 3 | try-fix | Leave presentation defaults; use private UISearchControllerDelegate to relayout results controller/table during presentation. |
❌ FAIL | 2 files | Built, but visual inspection showed suggestions overlapped/appeared behind the search UI; tightened geometry check measured verticalGap = -104. |
| 4 | try-fix | Scope native presentation opt-out to iPhone result searches; fix discovery guard and add required iOS 26 screenshot baseline. | ✅ PASS | 3 files | Better than PR: narrower behavior change plus complete UI test assets. |
| PR | PR #32931 | Unconditionally disable nav-bar hiding/background obscuring for Shell UISearchController; add iOS screenshot UI test. |
❌ FAILED (Gate) | 4 files | Original PR; broad iPad-impact risk and missing/non-discoverable test behavior. |
Cross-Pollination
| Model | Round | New Ideas? | Details |
|---|---|---|---|
| maui-expert-reviewer | 1 | Yes | Proposed phone-scoped native flag fix, results-renderer inset/layout alternatives, delegate relayout, and TitleView fallback. |
| maui-expert-reviewer | 2 | Yes | After try-fix-1 compile failure, recommended Assert.Ignore runtime guard and a results-renderer layout approach. |
| maui-expert-reviewer | 3 | Yes | After RS0016 failure, recommended private UISearchControllerDelegate relayout to avoid public API changes. |
| maui-expert-reviewer | 4 | No blocking findings | Reviewed passing scoped candidate; verdict LGTM once snapshot baseline is included. |
Exhausted: No
Selected Fix: Candidate #4 — it is the only candidate that passed the targeted iOS UI test and is demonstrably better than PR #32931 because it scopes the UIKit behavior change to the reported iPhone + results scenario, fixes cross-platform test discovery, and includes the missing screenshot baseline.
Report — Final Recommendation
Comparative Analysis — PR #32931
Candidate ranking
| Rank | Candidate | Regression result | Assessment |
|---|---|---|---|
| 1 | try-fix-4 |
✅ PASS | Best candidate. It preserves the PR's effective UIKit workaround while scoping it to SearchHandler.ShowsResults on iPhone, fixes cross-platform test discovery, adds screenshot retry, and includes the required iOS 26 baseline. |
| 2 | pr-plus-reviewer |
Not rerun in this phase | Better than raw PR because the expert feedback was applied in sandbox form, but it lacks the recorded passing regression evidence that try-fix-4 has. |
| 3 | pr |
❌ FAILED | Functional direction is plausible, but the gate failed because the screenshot baseline was missing; it also applies an iPhone-specific behavior change unconditionally to broader UIKit Shell search scenarios. |
| 4 | try-fix-3 |
❌ FAIL | Avoided public API changes, but visual/geometry validation showed the suggestions were moved too far upward and overlapped the search UI (verticalGap = -104). |
| 5 | try-fix-2 |
❌ FAIL | Tried a results-renderer layout/inset fix, but failed build because public overrides required PublicAPI entries; adding public API for this internal layout workaround is not desirable. |
| 6 | try-fix-1 |
❌ FAIL | Had the right scoped implementation idea, but used an unavailable IgnoreIfPlatforms helper and failed compilation. |
Winner
try-fix-4 is the single winning candidate. It is the only candidate with a recorded passing targeted iOS UI test, and candidates that failed regression tests are ranked lower as required. It also incorporates the best expert-review feedback: scope the UIKit presentation change to the reported iPhone results scenario, keep non-iOS test discovery intact, use screenshot retry for UIKit animation timing, and include the missing snapshot baseline.
Future Action — alternative fix proposed (try-fix-4)
Automated review — alternative fix proposed
The expert-reviewer evaluation compared the PR fix against automatically generated candidates and selected try-fix-4 as the strongest fix.
Why: try-fix-4 is the only candidate with a recorded passing targeted iOS UI regression run. It keeps the effective UISearchController workaround but scopes it to iPhone result searches, fixes test discovery/flakiness, and includes the missing screenshot baseline.

Description of Change
On iPhone, when tapping a SearchHandler, the navigation bar hides and the search bar animates upward. The suggestions list was not following this movement, creating a visible gap. iPad and Android work correctly.
Root cause: When
HidesNavigationBarDuringPresentationistrue(the iOS default), the navigation bar hides during search presentation and the search bar animates upward, but the suggestions list doesn't follow properly on iPhone.Fix: Set
HidesNavigationBarDuringPresentation = falseandObscuresBackgroundDuringPresentation = falseon theUISearchControllerwhen it's created inShellPageRendererTracker.AttachSearchController(). This prevents the navigation bar from hiding during search presentation, keeping the suggestions list correctly attached to the search bar.This approach is based on a working workaround provided by @pictos in the issue comments.
