Sorting an Array in Swift

Define a initial names array:

var names = [ "gamma", "Alpha", "alpha", "bravo"]

Method 1:

var sortedNames = sorted(names, {$0 < $1})
// sortedNames becomes "[Alpha, alpha, bravo, gamma]"

This can be further simplified to:

var sortedNames = sorted(names, <)
// ["Alpha", "alpha", "bravo", "gamma"]
var reverseSorted = sorted(names, >)
// ["gamma", "bravo", "alpha", "Alpha"]

Method 2:

names.sort(){$0 < $1}
// names become sorted as this --> "[Alpha, alpha, bravo, gamma]"
