Calendar.components cannot be used with an array literal in Swift 3

Question

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?

Here is what I have so far that won't compile but from reading other's code it has worked in the past:

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

        }
    }
}

`var currentDateString: Int {` returns an Int ??? Doesn't make sense — Leo Dabus, Jan 15 '17 at 04:11
You are supposed to use DateFormatter. `formatter.dateStyle = .full` — Leo Dabus, Jan 15 '17 at 04:18
You can use this as reference and make it full instead of short. http://stackoverflow.com/a/28347285/2303865 — Leo Dabus, Jan 15 '17 at 04:24

Maybe you may need to use dateComponents(_:from:) rather than component(_:from:):

let componetsThatWeWant = calendar.dateComponents([.year, .day, .month], from: date)

But using DateFormatter seems to be a better choice.
