Greetings from Syncfusion.
We have validated your query and we suspect that the SfRangeSliderRenderer has not been added in your AppDelegates.cs file in iOS project. You can refer the below documentation link to know about the renderer
If you still face the same issue provide sample based on your application along with replication procedure. This will be helpful for us to investigate further and provide you a better solution at the earliest.
