Crash with SfPullToRefresh

[Paul Ruedisueli]

I am using SfPullToRefresh in a Xamarin.Forms application with the latest Xamarin.Forms package. I am also using the new feature Shapes in the application.

This is the error:

Hi Jasper, 

Thanks for using Syncfusion controls. 

We have checked the reported issue “Application crashed when using SfPullToRefresh” in Xamarin forms IOS. After analysis, we have found that this issue is not related to our library it is related to Xamarin forms version 4.7. Same issue is already logged in Xamarin framework.    

   

You can track the status of the issue report by the following link.
