title: How can a sync of IOS reminders programmatically be triggered / forced?
body: <p>I am writing a task mgmt app that is using EKReminder. 
  Works perfectly when using on one iOS device. </p>
  
  <p>When I use on two devices (same apple account), I realise that reminder changes sync is with significant delay and even often incomplete. (tried iCloud, google, company outlook)</p>
  
  <p>This thus seems unrelated to my app (same happens if I change reminders directly in Reminder iOS app).  </p>
  
  <p>Can I programmatically force a sync of reminders with whatever service (e.g. iCloud) that they are linked to and trigger this out of my app? </p>
