I added follow code in my project, and it worked on debug mode(both simulator and phsical device), but when I release version to appstore testflight, It crashed app on the start moment.

Version is: 2020.2.513.1, from Nuget

<telerikPrimitives:RadBusyIndicator x:Name="busyIcon"
    IsBusy="True" />


Crash log:

Hi Lion,

Thank you for sending the snippet and the exception.

We have been reported similar exception when RadBusyIndicator is used. The issue could be reproduced when the Linker Behavior of the iOS project is set to "Link All".  Currently we do not fully support stripping our assemblies, we have this logged as a feature request in our public portal, you could cast your vote and track its status at the link below:

In the meantime, in order to resolve this you could use "Link Framework SDKs Only" option of the Linker Behavior.  The other alternative is to stay with "Link All", but exclude the Telerik.XamarinForms.Common.dll assembly from the linker process as described here: 

If you choose the second approach, you would need to add the following in the "Additional mtouch arguments" field:


I hope I was of help.  Let me know if any additional questions on this arise.
