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

  • Setting the ActivityIndicator's IsRunning property to true and then setting it back to false causes the ActivityIndicator to freeze and to remain visible.

Root Cause

Description of Change

  • Replace activityIndicatorView.Hidden = activityIndicator.Visibility != Visibility.Visible with activityIndicatorView.Hidden = true in the else-else branch of UpdateIsRunning, ensuring the native UIActivityIndicatorView is always hidden when not both running and visible, preventing the frozen static frame regression on iOS/MacCatalyst.

Issues Fixed

Fixes #36173

Pull request overview

Fixes an iOS/MacCatalyst regression where ActivityIndicator could stop animating but remain visible as a “frozen” static frame after IsRunning is set to false, by ensuring the native UIActivityIndicatorView is hidden whenever it isn’t both running and visible.

Changes:

  • Update iOS UpdateIsRunning logic to always hide the native view when not (IsRunning && Visibility.Visible) to prevent the frozen-frame state.
  • Add an iOS handler device test validating that transitioning IsRunning from true to false hides the native view even when Visibility is Visible.

File Description
src/Core/src/Platform/iOS/ActivityIndicatorExtensions.cs Ensures UIActivityIndicatorView.Hidden is set to true when not running, preventing the visible-but-not-animating frozen frame.
src/Core/tests/DeviceTests/Handlers/ActivityIndicator/ActivityIndicatorHandlerTests.iOS.cs Adds a regression test asserting the native view becomes hidden after setting IsRunning = false while visible.

Issue: #36173 - [iOS] ActivityIndicator freezes and remains visible after setting IsRunning to false - regression in Microsoft.Maui.Controls > 10.0.51
PR: #36263 - [iOS/MacCatalyst] Fix ActivityIndicator frozen static frame when IsRunning is set to false
Platforms Affected: iOS, MacCatalyst
Files Changed: 1 implementation, 1 test

Key Findings

  • Issue #36173 is a verified iOS regression introduced after 10.0.51: toggling ActivityIndicator.IsRunning from true to false leaves a frozen static spinner visible.
  • PR #36263 changes src/Core/src/Platform/iOS/ActivityIndicatorExtensions.cs so stopped/non-collapsed indicators are hidden instead of restoring Hidden=false when Visibility=Visible.
  • PR #36263 adds an iOS Core device test in ActivityIndicatorHandlerTests.iOS.cs for IsRunning=false while Visibility=Visible.
  • Gate result was provided by the caller and was not re-run: Gate PASSED - tests fail without fix and pass with PR fix.
  • Local gh is unauthenticated, so PR required-check status could not be queried via gh pr checks --required.

Code Review Summary

Verdict: NEEDS_DISCUSSION
Confidence: low
Errors: 0 | Warnings: 0 | Suggestions: 0

Key code review findings:

  • No code correctness findings were found. Confidence is low only because required CI status could not be verified in this environment.
  • Blast radius is localized to iOS/MacCatalyst ActivityIndicator IsRunning/Visibility mapping; no startup path or static/shared state changes.

Fix Candidates

# Source Approach Test Result Files Changed Notes
PR PR #36263 In ActivityIndicatorExtensions.UpdateIsRunning, hide the native view whenever the indicator is not both running and visible, while preserving collapsed layout behavior. PASSED (Gate provided) ActivityIndicatorExtensions.cs, ActivityIndicatorHandlerTests.iOS.cs Original PR fix; gate was completed before this run.
🔬 Code Review — Deep Analysis

Code Review - PR #36263

Independent Assessment

What this changes: iOS/MacCatalyst ActivityIndicator now hides the native UIActivityIndicatorView whenever it is not both IsRunning and Visibility.Visible.
Inferred motivation: Prevent a stopped spinner from remaining visible as a frozen static frame.

Reconciliation with PR Narrative

Author claims: Fixes iOS/MacCatalyst frozen ActivityIndicator after IsRunning=false, caused by overwriting StopAnimating()'s hidden state.
Agreement/disagreement: Agrees. The code path matches the described root cause and preserves collapsed-vs-hidden layout behavior.

Prior Review Reconciliation

No prior Error findings found.

Blast Radius Assessment

  • Runs for all instances: Yes, but only iOS/MacCatalyst ActivityIndicator IsRunning/Visibility mappings.
  • Startup impact: No.
  • Static/shared state: No.

CI Status

  • Required-check result: Undetermined - gh pr checks --required unavailable due missing GitHub CLI authentication.
  • Classification: Undetermined.
  • Action taken: Supplemental REST context and local review branch were used; confidence capped low.

Findings

No Errors, Warnings, or Suggestions found.

Failure-Mode Probing

  • IsRunning=false, Visibility.Visible: native view stops and is hidden; PR test covers this.
  • Visibility.Collapsed: still applies collapse constraint and hides.
  • Visibility.Hidden: inflates and hides, preserving layout space.
  • Handler reconnect/layout redraw: MauiActivityIndicator still gates animation on running-and-visible.

Verdict: NEEDS_DISCUSSION

Confidence: low
Summary: Code review found no correctness issues; the implementation is localized and sound. Required CI status could not be verified with authenticated gh, so this cannot be LGTM under the skill rules.

🛠️ Fix — Analysis & Comparison

Fix Candidates

# Source Approach Test Result Files Changed Notes
1 try-fix UIKit HidesWhenStopped owns stopped hidden state; MAUI avoids overriding it for Visible && !IsRunning. BLOCKED 2 files Built, but iOS run produced no xUnit results (Passed: 0, Failed: 0) and a crash report.
2 try-fix Move full ActivityIndicator state reconciliation into MauiActivityIndicator and call it from the handler. BLOCKED 2 files Initial compile issue fixed; build then succeeded, but iOS results collection was blocked. Broader lifecycle blast radius.
3 try-fix Handler-level effective visibility: call baseline UpdateIsRunning, then UpdateVisibility() using combined running/visibility state. BLOCKED 1 file Build succeeded, but iOS results collection was blocked. Duplicates visibility/layout application.
4 try-fix Effective opacity masking: set native Alpha=0 when not running and visible, with an opacity mapper override. BLOCKED / NOT BETTER 3 files Build produced PublicAPI analyzer warnings and still lacked test results; masks symptom and increases API/risk surface.
PR PR #36263 Directly hide the native view in ActivityIndicatorExtensions.UpdateIsRunning whenever not both running and visible, preserving collapsed layout handling. PASSED (Gate) 2 files Original PR. Gate was already completed by the caller and was not re-run.

Cross-Pollination

Model Round New Ideas? Details
maui-expert-reviewer 1 Yes Candidate 1: restore UIKit HidesWhenStopped ownership.
maui-expert-reviewer 2 Yes Candidate 2: move state reconciliation into MauiActivityIndicator.
maui-expert-reviewer 3 Yes Candidate 3: handler-level effective visibility via UpdateVisibility().
maui-expert-reviewer 4 Yes Candidate 4: effective opacity masking. This was tested and rejected as not better.

Exhausted: Yes
Selected Fix: PR #36263 - The original PR is the only fix with a provided passing gate result. No alternative was demonstrably better: candidates 1-3 could not obtain valid local iOS test results, and candidate 4 introduced PublicAPI warnings plus higher behavioral risk.

Environment/Test Blocker

All local iOS candidate test runs used:

pwsh .github/skills/run-device-tests/scripts/Run-DeviceTests.ps1 -Project Core -Platform ios -TestFilter "Category=ActivityIndicator"

Each candidate either built successfully or was fixed to build, but xharness failed to copy test-results.xml from the simulator, reported Passed: 0 and Failed: 0, and attached a crash report. Per the try-fix rules, those runs are not valid passes.

🏁 Report — Final Recommendation

Comparative Fix Report - PR #36263

Summary

Winner: pr

The raw PR fix is the only candidate with a supplied passing regression gate: the new ActivityIndicator device test fails without the fix and passes with the fix. The expert reviewer found no actionable issues, so pr-plus-reviewer is identical to pr; the try-fix alternatives were either blocked from producing valid iOS regression results or introduced broader risk.

Candidate Ranking

Rank Candidate Regression Result Assessment
1 pr PASSED Direct, localized fix in ActivityIndicatorExtensions.UpdateIsRunning; preserves collapsed layout behavior and has a passing gate.
2 pr-plus-reviewer PASSED by equivalence Expert review produced no actionable findings, so this candidate is identical to pr and adds no improvement over the raw PR.
3 try-fix-1 BLOCKED Delegates stopped-hidden behavior to UIKit HidesWhenStopped; build succeeded but no valid xUnit result was produced, and the approach depends on UIKit side effects.
4 try-fix-3 BLOCKED Applies effective visibility at the handler mapper layer after UpdateIsRunning; build succeeded but no valid xUnit result was produced, and it duplicates visibility/layout reconciliation.
5 try-fix-2 BLOCKED Moves full state reconciliation into MauiActivityIndicator; compile issue was corrected and build succeeded, but no valid xUnit result was produced, and the lifecycle blast radius is broader.
6 try-fix-4 BLOCKED / NOT BETTER Uses opacity masking; produced PublicAPI analyzer warnings and has higher behavioral risk because alpha-zero is not equivalent to native hidden semantics.

Comparative Analysis

pr changes the exact failing branch: after StopAnimating(), non-collapsed states now inflate layout space and set Hidden = true instead of deriving hidden state from MAUI Visibility. This directly fixes the frozen visible static frame while keeping Collapsed separate so layout constraints still collapse native size.

pr-plus-reviewer was evaluated as a sandbox candidate, but the expert review returned zero inline findings and no recommended edits. Since it is identical to the PR, it cannot outrank the raw PR on simplicity or evidence.

The try-fix candidates explored plausible alternatives, but none produced a valid passing regression result. Per the ranking rule, candidates without a passing regression signal must rank below candidates that passed. Among them, try-fix-1 is the closest conceptually but relies on HidesWhenStopped; try-fix-3 and try-fix-2 broaden the reconciliation surface; try-fix-4 is least suitable because it masks output with opacity and introduced analyzer/API-surface concerns.

Recommendation

Keep the PR implementation as submitted. It is the smallest proven fix, has the strongest empirical evidence, and the expert review found no actionable changes to apply.

[iOS/MacCatalyst] Fix ActivityIndicator frozen static frame when IsRu…

…nning is set to false (#36263)

<!-- Please let the below note in for people that find this PR -->
> [!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](https://github.com/dotnet/maui/wiki/Testing-PR-Builds) from

Thank you!

### Issue Details
- Setting the ActivityIndicator's IsRunning property to true and then
setting it back to false causes the ActivityIndicator to freeze and to
remain visible.

### Root Cause
- PR #28983 added Hidden = activityIndicator.Visibility !=
Visibility.Visible which runs after StopAnimating(). HidesWhenStopped
correctly set Hidden=True, but this line immediately overwrote it with
Hidden=False (since Visibility=Visible), leaving the native view visible
with no animation — the frozen static frame.

### Description of Change
- Replace activityIndicatorView.Hidden = activityIndicator.Visibility !=
Visibility.Visible with activityIndicatorView.Hidden = true in the
else-else branch of UpdateIsRunning, ensuring the native
UIActivityIndicatorView is always hidden when not both running and
visible, preventing the frozen static frame regression on
iOS/MacCatalyst.

### Issues Fixed
Fixes #36173

### Validated the behaviour in the following platforms

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

else-else branch of UpdateIsRunning, ensuring the native
UIActivityIndicatorView is always hidden when not both running and
visible, preventing the frozen static frame regression on
iOS/MacCatalyst.

### Issues Fixed
Fixes #36173

### Validated the behaviour in the following platforms

- [ ] Windows

[iOS/MacCatalyst] Fix ActivityIndicator frozen static frame when IsRu…
9b0b651 
…nning is set to false (#36263)

<!-- Please let the below note in for people that find this PR -->
> [!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](https://github.com/dotnet/maui/wiki/Testing-PR-Builds) from
this PR and let us know in a comment if this change resolves your issue.
Thank you!

### Issue Details
- Setting the ActivityIndicator's IsRunning property to true and then
setting it back to false causes the ActivityIndicator to freeze and to
remain visible.

### Root Cause
- PR #28983 added Hidden = activityIndicator.Visibility !=
Visibility.Visible which runs after StopAnimating(). HidesWhenStopped
correctly set Hidden=True, but this line immediately overwrote it with
Hidden=False (since Visibility=Visible), leaving the native view visible
with no animation — the frozen static frame.

### Description of Change
- Replace activityIndicatorView.Hidden = activityIndicator.Visibility !=
Visibility.Visible with activityIndicatorView.Hidden = true in the
else-else branch of UpdateIsRunning, ensuring the native
UIActivityIndicatorView is always hidden when not both running and
visible, preventing the frozen static frame regression on
iOS/MacCatalyst.
