How to create a Set of integers in Swift ?

Answer

To create a Set of integers in Swift, you can use the Set data structure.

✐ Examples

1 Create Set of Integers

In this example,

We declare a Set of integers using the Set() initializer.
We add integers to the set using the insert method.
The resulting set contains unique integers without duplicates.

Swift Program

var numberSet = Set<Int>()

// Adding integers to the set
numberSet.insert(1)
numberSet.insert(2)
numberSet.insert(3)
numberSet.insert(4)
numberSet.insert(5)

// Printing the set
print("Set of integers:", numberSet)

Output

Set of integers: [5, 2, 3, 1, 4]

2 Create Set of Integers using Array Literal

In this example,

We declare a Set of integers using an array literal syntax.
The array literal syntax initializes the set directly with integers.
The resulting set contains unique integers without duplicates.

Swift Program

var numberSet: Set<Int> = [1, 2, 3, 4, 5]

// Printing the set
print("Set of integers:", numberSet)

Output

Set of integers: [5, 2, 3, 1, 4]
