How to count the elements of a Set in Swift?

Swift supports the different types of generic collections and set is one of them. A set is used to store unordered values 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. In the Swift set, we can count the elements of the set. To do this we use the count property of the set. This property is used to count the total number of values available in the specified set.

Syntax:

setName.count

Here, 

setName is the object of the set class.

Return Value: It will return the total number of values present in the given set. 

Example 1:

Output:

Total number of elements in the set: 6
Total number of elements in the set: 0

Example 2:

Output:

Set contains more employee name
