How to Iterate Over a Set in Swift - Step by Step Examples

How to Iterate Over a Set in Swift ?

To iterate over a set in Swift, you can use a for-in loop.

In this example,

let stringSet: Set<String> = ["Apple", "Banana", "Orange"]
for string in stringSet {
    print(string)
}

Apple
Banana
Orange

In this example,

We define a set of integers named intSet containing various integer values.
We use a for-in loop to iterate through each element in the intSet.
Within the loop, we perform a specific operation or print each integer element to the console.

let intSet: Set<Int> = [1, 2, 3, 4, 5]
for number in intSet {
    print(number * 2)
}

In this tutorial, we learned How to Iterate Over a Set in Swift language with well detailed examples.
