How to shuffle the elements of a set in Swift?

A set is an unordered generic collection that is used to store elements of the same type. It means you are not allowed to keep different types in the set. You can use a set instead of an array if the order of the values is not defined or you want to store unique values. It doesn't keep duplicate values, it always keeps unique values in it. It generally uses a hash table to store the elements. A set can be mutable or immutable. If a set is assigned to a variable then that set is known as a mutable set. Or if a set is assigned to a constant then that set is known as an immutable set. In Set, we can easily shuffle the elements using the shuffled() function. This function is used to shuffle all the elements from the specified set. It does not take any parameters.

Syntax:

setName.shuffled()

Here, 

setName is the object of the set class.

Return Value: It will return the shuffled elements of the specified set.

Example 1:

Output:

Original Set: [458, 76, 982, 8, 5, 4, 3, 65, 2]
Shuffled elements: [65, 5, 4, 982, 76, 8, 2, 3, 458]

Example 2:

Output:

Original Set: ["Rahul", "Mira", "Sumit", "Pihu", "Punit"]
Final Set: ["Sumit", "Rahul", "Pihu", "Punit", "Mira"]
