Thank you for contacting Syncfusion support.
Based on the provided information, we have checked your query with Schedule performance in Xamarin.Forms. As per our implementation, we are adding the appointments in the UI when the dates changed in Schedule, while swiping we have created / added the specific view appointments alone in the particular view. So that, Schedule is feasible with performance while swiping between the months. We have prepared simple sample with certain number of appointments (60) in a month, please find the following sample for the same by the following link,
