How to get Subset from a Set in Swift


How to get Subset from a Set in Swift ?

Answer

To get a subset from a Set in Swift, you can use the filter method to filter elements based on a condition.



✐ Examples

1 Get Subset of Even Numbers from a Set

In this example,

  1. We create a Set named numbers and initialize it with some integer elements.
  2. We use the filter method on the Set to filter the elements that satisfy a specific condition (in this case, being even).
  3. The filter method returns a new Set containing only the elements that satisfy the condition.
  4. We print the subset to the console to verify the result.

Swift Program

import Foundation

let numbers: Set<Int> = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
let evenNumbers = numbers.filter { $0 % 2 == 0 }
print("Subset of even numbers:")
for number in evenNumbers {
    print(number)
}

Output

Subset of even numbers:
2
4
6
8
10

2 Get Subset of Numbers Greater Than 5 from a Set

In this example,

  1. We create a Set named numbers and initialize it with some integer elements.
  2. We use the filter method on the Set to filter the elements that are greater than 5.
  3. The filter method returns a new Set containing only the elements that satisfy the condition.
  4. We print the subset to the console to verify the result.

Swift Program

import Foundation

let numbers: Set<Int> = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
let numbersGreaterThanFive = numbers.filter { $0 > 5 }
print("Subset of numbers greater than 5:")
for number in numbersGreaterThanFive {
    print(number)
}

Output

Subset of numbers greater than 5:
6
7
8
9
10

Summary

In this tutorial, we learned How to get Subset from a Set in Swift language with well detailed examples.
