how to check if two sets are disjoint in swift

To determine if two sets are disjoint in Swift, you can check if their intersection is an empty set. Here's the code:

main.swift
let set1: Set<Int> = [1, 2, 3, 4]
let set2: Set<Int> = [5, 6, 7]

if set1.intersection(set2).isEmpty {
    print("The two sets are disjoint")
} else {
    print("The two sets have at least one element in common")
}

In this example, we create two sets set1 and set2. We then use the intersection method to find their intersection and check if it's isEmpty. If it's empty, we can conclude that the two sets are disjoint. If it's not empty, then the two sets have at least one element in common.

This approach works for any type of set in Swift, not just Set<Int>.
