title: correct way to add an event to the iOS calendar with standard dialog?
body: <p>currently im using this code snippet to add an event to the calendar</p>
  
  <pre><code>let date = NSDate()
  let calendar = NSCalendar.current
  let hour = calendar.component(.hour, from: date as Date)
  let minutes = calendar.component(.minute, from: date as Date)
  self.addEventToCalendar(title: "lol", description: "lal", startDate: date, endDate: date)
  </code></pre>
  
  <p>which is not refined, but it works. I have 2 questions:</p>
  
  <p>is there a way to use the same form for adding an event to the iOS calendar as you see when iOS recognises a date in your e-mails?</p>
  
  <p>is there a way to directly transform a string in to a date? I get the date from the backend like: 31.12.2016 22:30:00 (DD.MM.YYYY HH:MM:SS).</p>
