Swift Array count

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

// count total number of elements in languages
var result = languages.count

print(result)

// Output: 3

count Syntax

The syntax of the array count property is:

array.count 

Here, array is an object of the Array class.

count Return Values

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

Example 1: Swift Array count

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

// count total elements on names 
print(names.count)  

var employees = [String]()

// count total elements on employees
print(employees.count)

Output

3
0

In the above example, since

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

Example 2: Using count With if...else

var numbers = [1,2,3,4,5,6,7,8,9,10]

// true because there are 10 elements on numbers
if (numbers.count > 5) {

  print( "The array size is large")
}

else {

  print("The array size is small")
}

Output

The array size is large

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

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