The reason for the error looks like the Microsoft Xamarin.iOS linker stripped out the Telerik.XamarinForms.Common assembly from the app package when it was compiled.
We do not support full linking (i.e. "LinkAll") as it is very aggressive and strips out any dependencies that has not direct usage in your app code.
There are two ways you can solve this:
Set the linker to SDK Assemblies Only so that it doesn't strip out 3rd party libraries
Use linkskip for the Telerik assemblies. See Linking on iOS - Controlling the Linker - Skipping Assemblies documentation.
Specifically, to avoid this error, you would skip Telerik.XamarinForms.Common.
However, to be safe, I would skip all the other ones that are referenced in that project as well.
--linkskip=Telerik.XamarinForms.Common --linkskip=Telerik.xxxxxx --linkskip=Telerik.xxxxxx --linkskip=Telerik.xxxxxx
If you run into any further trouble after setting the LinkerBehavior or linkskip, open a Support Ticket here so that the Xamarin team can directly assist.
