Swift Set count

var employees: Set = ["Ranjy", "Sabby", "Pally"]

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

print(result)

// Output: 3

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

var names: Set = ["Gregory", "Johnny", "Kate"]

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

var employees = Set<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 set, the property returns 0.

Example 2: Using count With if...else

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

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

  print( "The set size is large")
}

else {

  print("The set size is small")
}

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.
