Swift Set isEmpty

isEmpty Syntax

The syntax of the set isEmpty property is:

set.isEmpty 

Here, set is an object of the Set class.

isEmpty Return Values

The isEmpty property returns:

• true - if the set does not contain any elements
• false - if the set contains some elements

Example 1: Swift set isEmpty

Output

false
true

In the above example, since

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

Example 2: Using isEmpty With if...else

Output

Elements: ["Federer", "Thiem"]

Here, the names set is not empty, so the if block is skipped and the else block is executed.
