ios - Sorting NSArray containing NSDate objects

Question

I have an array containing NSDate objects. With Objective-C, I am able to sort this array by using:

NSArray *array = [unsortedArray sortedArrayUsingSelector:@selector(compare:)]

I'm wondering if there's a Swift equivalent of doing this same thing. Relatively new to Swift here, hacking my way through.

If you use Swift array.

let datesArray = [ NSDate(), NSDate(timeIntervalSinceNow: 60), NSDate(timeIntervalSinceNow: -60) ]
let sorter: (NSDate, NSDate) -> Bool = { $0.compare($1) == .OrderedAscending }
let sortedDatesArray = datesArray.sort(sorter)
