Swift Array isEmpty

The isEmpty property checks if the array is empty or not.


var languages = ["Swift", "C", "Java"]

// check if leanguages is empty or not var result = languages.isEmpty
print(result) // Output: false

isEmpty Syntax

The syntax of the array isEmpty property is:


Here, array is an object of the Array class.

isEmpty Return Values

The isEmpty property returns:

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

Example 1: Swift Array isEmpty

var names = ["Gregory", "Perry", "Nadal"]

// check if names is empty or not print(names.isEmpty)
var employees = [String]()
// check if employees is empty or not print(employees.isEmpty)



In the above example, since

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

Example 2: Using isEmpty With if...else

var names = [String]()

// true because names is an empty array if (names.isEmpty) {
print( "Array is empty") } else { print("Elements:", names) }


Array is empty

Here, the names array is empty, so the if block is executed.
