Thank you for contacting Syncfusion Support.
In Xamarin.Forms, there is an in-build class called Command which you can use it. However, in Xamarin.iOS there is no such class and you need to write a command implementing from theICommand interface in your sample in order to use commands in Xamarin.iOS.
Please refer the below code example for the Command class implementation.
