// Swift program to perform union operation 
// between two Set collections

import Swift

var FirstSet:Set<Int>  = [10, 20,30]
var SecondSet:Set<Int> = [40, 50,60]

print("First set : ",FirstSet)
print("Second set: ",SecondSet)
print("Union of set: ",FirstSet.union(SecondSet))

Output:

First set :  [20, 30, 10]
Second set:  [40, 60, 50]
Union of set:  [30, 20, 60, 10, 40, 50]
