How to add an Item to a Set in Swift - Step by Step Examples

How to add an Item to a Set in Swift ?

In Swift, you can add an item to a Set using the insert() method.

In this example,

We create a Set named numbers containing some integer elements.
We use the insert() method of numbers to add a new integer element, such as 6, to the set.
Now, numbers contains the added element 6.

var numbers: Set<Int> = [1, 2, 3, 4, 5]
numbers.insert(6)
print("Numbers: \(numbers)")

Numbers: [3, 4, 5, 6, 1, 2]

In this example,

We create a Set named fruits containing some string elements.
We use the insert() method of fruits to add a new string element, such as "Orange", to the set.
Now, fruits contains the added element "Orange".

var fruits: Set<String> = ["Apple", "Banana", "Cherry"]
fruits.insert("Orange")
print("Fruits: \(fruits)")

Fruits: ["Banana", "Cherry", "Orange", "Apple"]
