Xamarin.iOS / SfDataGrid on iPhone 10 is crashing

Question

I have been using SfDataGrid in a deployed application for over a year without any issues. Recently the iPhone 10 was released and I noticed that the datagrid is crashing, but only on iPhone 10. Previous phones work without any issues.

Below is the error and stack trace from the crash and it is coming from within the SfDataGrid component:

Object reference not set to an instance of an object

Does anyone know if there's a fix for this?

I did notice that a basic configuration of the SfDataGrid does work ok even on iPhone 10, but when I start using more custom configuration options in the grid it starts to crash. I have not been able to pin point which specific configuration is causing this just yet.

Any help / info would be appreciated.
