With R1 2019 release of Telerik UI for Xamarin we've introduced the following features related to the scheduling capabilities of RadCalendar:

• Built-in UI for creation and modification of appointments, for more details on this check Scheduling UI topic.
• Recurrent appointments, please go to Recurrence Overview topic for detailed information.

Basically, this covers the most common features of scheduler control, so I've updated the status of this feature request to "Completed".

To all interested parties, it will be useful if you can share what particular features would you expect from such a component and in what use cases you plan to use it.
This will help us tremendously when we work on spec for the component.
