How to Get Length of a Set in Swift

How to Get Length of a Set in Swift ?

Answer

To get the length of a set in Swift, you can use the count property of the Set type.


✐ Examples

1 Get Length of a Set with Elements

In this example,

  1. We declare a variable named mySet and initialize it with a set of string elements using the Set type.
  2. We use the count property of mySet to get the number of elements in the set.
  3. Finally, we print the length of the set to the console using print.

Swift Program

var mySet: Set<String> = ["apple", "banana", "orange"]

// Get the length of the set
let length = mySet.count

// Print the length of the set
print("Length of the set: \(length)")

Output

Length of the set: 3

2 Get Length of an Empty Set

In this example,

  1. We declare an empty set variable named emptySet using the Set type and initialize it with no elements.
  2. We use the count property of emptySet to get the number of elements in the set.
  3. Finally, we print the length of the set to the console using print.

Swift Program

var emptySet = Set<String>()

// Get the length of the empty set
let length = emptySet.count

// Print the length of the empty set
print("Length of the empty set: \(length)")

Output

Length of the empty set: 0
