title: Calendar.components cannot be used with an array literal in Swift 3
body: <p>I'm attempting to build a class's blueprint in order to display the current date as i.e. "Saturday January 14, 2017" but I'm unable to create an array of calendar components in Swift 3.  Will I need to break them up into separate variables like I've done for the year below and then combine each variable into a string?</p>
  
  <p>Here is what I have so far that won't compile but from reading other's code it has worked in the past: </p>
  
  <pre><code>import Foundation
  class CurrentCalendarDate {
      var currentDateString: String {
          get{
              let date = Date()
  
              let calendar = Calendar.current
  
              //let components = calendar.component(.year, from: date)
  
              let componetsThatWeWant = calendar.component([.year, .day, .month], from: date)
  
              let readableDate: String = "Today's date is: \(componetsThatWeWant.day) \(componetsThatWeWant.month), \(componetsThatWeWant.year)"
  
              return readableDate
  
          }
      }
  }
  </code></pre>
