title: create a custom UIDatePicker that is suitable for making appointments in swift
body: <p>I would like to create a UDatePicker to allow users to make an appointment. The UIDatePicker should show 7 days ahead of the current day, and after the appointment is made, a notification will pop up showing that it is confirmed. </p>
  
  <p>The UI doesn't matter, something basic is fine. Is that possible? I've been searching online but I couldn't find anything that could help.</p>
  
  <p>Any help would be appreciated.</p>
