Problem Solution:

Here, we will create two sets of integer elements using the Set collection. Then we will check a set is the superset of another set or not using the isSuperset() function.

Program/Source Code:

The source code to check a set is the superset of another set collection is given below. The given program is compiled and executed successfully.

// Swift program to check a set is the superset 
// of another set collection

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(FirstSet.isSuperset(of: SecondSet))
{
    print("FirstSet is the superset of SecondSet.")
}
else
{
    print("FirstSet is not superset of SecondSet.")
}

Output:

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

...Program finished with exit code 0
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 isSuperset() function to check FirstSet is the superset of SecondSet using isSuperset() function. The isSuperset() function return Boolean value and then we printed the appropriate message on the console screen.
