Swift Set count

count Syntax

The syntax of the set count property is:

set.count 

Here, set is an object of the Set class.

count Return Values

The count property returns the total number of elements present in the set.

Example 1: Swift Set count

Output

3
0

In the above example, since

• names contain three string elements, the property returns 3.
• employees is an empty set, the property returns 0.

Example 2: Using count With if...else

Output

The set size is large

In the above example, we have created the set named numbers with 10 elements.

Here, since there are 10 elements in the set, numbers.count > 5 evaluates to true, so the statement inside the if block is executed.
