How to solve "System.MethodMissingException" in Xamarin.Forms.iOS when using DataGrid?
When creating Xamarin.Forms samples that uses SfDataGrid with Linker behavior in iOS renderer project as “Link Framework SDKs only”, System.MethodMissingException will be thrown. This error occurs based on the iOS version of the Xcode. It works fine in iOS 9.1 whereas will crash in 9.2 and versions earlier than 9.1. This is reproducible even in a simple scenario and has been reported as a bug in Bugzilla as well. You can see the details of it from the below thread.

However you can able to skip this error in two ways either by changing the “Linker Behavior” or by “Setting custom linker argument” which are explained below.
Changing Linker Behavior
To avoid this issue, please choose the Linker behavior as “Don’t Link” in the iOS renderer project.
Forms iOS Renderer Project -> Options -> iOS Build -> Linker behavior -> “Don’t Link |
Custom linker argument
You can also bypass this error by setting a custom linker argument. Check the documentation here. https://developer.xamarin.com/guides/ios/advanced_topics/linker/#Skipping_Assemblies
You can set an “mtouch” argument to skip the assembly which needs to be preserved. For this error, you will be able to run your app by skipping the System.Core assembly. Refer the below screenshot for more details.
