iOS – SfImageEditor toolbar buttons are tappable but unresponsive on iPhone - .NET MAUI 10.0.70

[Dieter Kutschus]

Hello,

attached is a minimal sample project that reproduces an issue with SfImageEditor on iOS.

Environment:

- .NET MAUI: 10.0.70

- Syncfusion.Maui.ImageEditor: 33.2.12

- Syncfusion.Maui.Core: 33.2.12

- Platform: iOS 16.7.16

- Device: iPhone 10.5 (physical device)

- .NET SDK: 10.0.301

Expected:

The app starts, the image is loaded into SfImageEditor, and toolbar buttons (crop, annotate, undo, etc.) respond to touch and perform the corresponding editing actions.

Actual:

The app starts and the image is displayed correctly. Toolbar buttons in SfImageEditor can be tapped (visual touch feedback may appear), but no editing action occurs — the control does not react to user input.

Sample project details:

- Minimal single-page MAUI app with SfImageEditor as the main content

- Image is loaded via stream-based loading (ImageSource.FromStream(() => new MemoryStream(imageBytes))), matching our production scenario

- ConfigureSyncfusionCore() is registered in MauiProgram.cs

- The sample includes LayoutLoopDetector.cs, which logs to the debug output when SizeChanged / MeasureInvalidated fire repeatedly

Reproduction steps:

1. Build and deploy the attached sample to an iPhone running iOS 16.7.16 or similar

2. Launch the app

3. Wait for the sample image to load in SfImageEditor

4. Tap any toolbar button (e.g. crop, text, shape, undo)

5. Observe that the button is touchable but no editing action is triggered

Additional notes:

- The issue is reproducible on the physical device listed above

- Image loading itself works; only toolbar interaction is affected

- We have not yet confirmed whether the issue also occurs on newer iOS versions or simulators

Please let us know if this is a known issue, if there is a recommended workaround, or if additional diagnostic information is needed.

Thank you.

Hello,

I'm following up on my earlier report about the unresponsive SfImageEditor toolbar buttons on iOS (sample project already attached). Are there any updates, a known cause, or a recommended workaround?

Thank you.

Hi Dieter,

Thank you for providing the sample project and detailed information.

We apologize for the inconvenience caused.

Currently we are validating the reported scenario.

Could you please confirm whether the same issue occurs on other iPhone devices or devices running different iOS versions? If the behavior is reproducible in other environments, please share the device models and iOS versions tested.

This information will help us investigate the issue further and identify whether it is specific to a particular device or iOS version.

Thank you for your cooperation. We look forward to your update.

Regards,
Vishal.

Hi Dieter,

Thank you for your patience.

We investigated the reported issue using an iPhone XR device available at our end. However, we do not currently have access to the specific iOS version reported (iOS 16.7.16). Based on our testing, we were unable to reproduce the reported behavior.

We have attached the test output for your reference.

Could you please update the device to the latest available iOS version and verify whether the issue still persists? This will help us determine whether the issue is specific to the reported OS version

Regards,
Vishal.
