Last Updated : June 26, 2021

Problem Solution

Here, we will create a set of integer elements using a Set collection with duplicate elements. But, Set collection automatically removes duplicate elements and prints the elements of created Set on the console screen.

Program/Source Code

The source code to create a simple set collection with duplicate elements is given below. The given program is compiled and executed successfully.

// Swift program to create a simple set collection 
// with duplicate elements

import Swift

let IntegerSet:Set = [10, 20, 30, 40,50,30,50,10]

print("Set elements without duplicate elements:")
for num in IntegerSet {
    print(num)
}

Output

Set elements without duplicate elements:
40
20
50
10
30

...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 an IntegerSet set of integer elements with some duplicate values. The Set collection automatically removes the duplicate elements. Then we printed all elements of the set IntegerSet using the for loop on the console screen.
