import Swift
var FirstSet:Set<Int>  = [1,2,3,4]
var SecondSet:Set<Int> = [2,3]

print("First set : ",FirstSet)
print("Second set: ",SecondSet)

if(SecondSet.isSubset(of: FirstSet))
{
    print("SecondSet is the subset of FirstSet")
}
else
{
    print("SecondSet is not subset of FirstSet")
}

Output:

First set :  [4, 2, 1, 3]
Second set:  [2, 3]
SecondSet is the subset of FirstSet

Press ENTER to exit console.

Explanation:

In the above program, we imported a package Swift to use the print() function using the below statement,

import Swift

Here, we created two sets FirstSet, SecondSet that contains integer elements. Then we used isSubset() function to check SecondSet is the subset of FirstSet using isSubset() function. The isSubset() function return Boolean value and then we printed the appropriate message on the console screen.
