How to Iterate Over a Set in Swift


How to Iterate Over a Set in Swift ?

Answer

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



✐ Examples

1 Iterate Over Set of Strings

In this example,

  1. We define a set of strings named stringSet containing various strings.
  2. We use a for-in loop to iterate through each element in the stringSet.
  3. Within the loop, we print each string element to the console.

Swift Program

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

Output

Apple
Banana
Orange

2 Iterate Over Set of Integers

In this example,

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

Swift Program

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

Output

2
4
6
8
10
