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
</>
Copy
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
Conclusion
In this Swift Tutorial, we learned how to find union of two Sets using Set.union() method.
