Swift – Find Union of Sets
To find union of Sets in Swift, call union() method on this Set and pass the other set as argument to it. Set.union() returns a new Set with the elements of the two Sets.
Examples
In the following example, we take two Sets: set1
and set2
, and find union of these two Sets using union() method.
main.swift
let set1: Set = [2, 4, 6, 8] let set2: Set = [2, 8, 14, 22] let result = set1.union(set2) print("Set 1 : \(set1)") print("Set 2 : \(set2)") print("Union : \(result)")
Output
Set 1 : [2, 6, 4, 8] Set 2 : [22, 2, 14, 8] Union : [2, 6, 22, 4, 14, 8] Program ended with exit code: 0
