Discussion
Use the shuffle() method to randomly reorder the elements of an array.
var names = ["Alejandro", "Camila", "Diego", "Luciana", "Luis", "Sofía"]
names.shuffle(using: myGenerator)
// names == ["Luis", "Camila", "Luciana", "Sofía", "Alejandro", "Diego"]
This method is equivalent to calling shuffle(using:), passing in the system’s default random generator.
Complexity: O(n), where n is the length of the collection.
