iOS App Crash When Setting Padding with ShowTrailingAndLeadingDates Set to False in Calendar

[Jon Kao]

Dear Syncfusion Support Team,

I would like to report an issue encountered while using the Syncfusion.Maui.Calendar component.

When setting the property ShowTrailingAndLeadingDates="False" and also applying a Padding value to the control, the app crashes on launch. Interestingly, this issue does not occur while running the app in Debug mode — it only crashes when the app is launched outside the debugger (e.g., in Release mode).

This appears to be a runtime crash specific to the combination of ShowTrailingAndLeadingDates="False" and the Padding property.

Could you please investigate this issue? Let me know if you need any additional information.

Thank you for your support!

Best regards.

Dear Syncfusion Support Team,

Thank you very much for the quick response and for providing the .nupkg file.

I’m currently working on a Mac and using Visual Studio Code for development, and I’m not quite sure how to install or reference a local .nupkg package in this environment. I’ve searched online but couldn’t find a clear guide for this setup.

Could you kindly provide instructions on how to install and use the provided .nupkg file in a .NET MAUI project on Mac using Visual Studio Code?

I really appreciate your support and the effort you’ve put into helping with this issue. Thank you again!

Best regards.

Hi Jon Kao,

Regarding Installing nupkg file on Mac using Visual Studio Code

To add a NuGet package source, you can execute the following command in your terminal:

dotnet nuget add source <PACKAGE_SOURCE_PATH>

Make sure to replace <PACKAGE_SOURCE_PATH> with the actual path to the NuGet package source. This command allows us to add a new package source to .NET environment, making it easier to manage dependencies and libraries.

For more information and guidelines, we can refer here:

Unfortunately, due to some issues on my end, I wasn’t able to successfully install and test the package. That said, I trust that the fix has been properly implemented based on your efforts and the details shared.

I truly appreciate your time and hard work in addressing this issue — thank you again for your continued support.

Best regards.
