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