Submitted by Nidhi, on June 29, 2021

Problem Solution:

Here, we will create two sets of integer elements using the Set collection. Then we will check both sets have some common elements or not using the isDisjoint() function.

Program/Source Code:

The source code to check two set collections contains common values or not is given below. The given program is compiled and executed successfully.

// Swift program to check two set collections 
// contain common values or not

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.isDisjoint(with: SecondSet))
{
    print("Both sets are identical.")
}
else
{
    print("Both sets have some common values.")
}

Output:

First set :  [2, 4, 1, 3]
Second set:  [3, 2]
Both sets have some common values.

...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 the isDisjoint() function to check both sets have some common elements or not. After that, we printed the appropriate message on the console screen.
