mutating func shuffle()

Discussion

Use the shuffle() method to randomly reorder the elements of an array.

var names = ["Alejandro", "Camila", "Diego", "Luciana", "Luis", "Sofía"]
names.shuffle()
// names == ["Luis", "Camila", "Luciana", "Sofía", "Alejandro", "Diego"]

This method is equivalent to calling shuffle(using:), passing in the system’s default random generator.
