Program/Source Code:

The source code to find the length of Set collection is given below. The given program is compiled and executed successfully.

// Swift program to find the length of 
// a Set collection

import Swift

var IntegerSet:Set<Int> = [10, 20,30,40,50]

print("Count of set elements is: ",IntegerSet.count)

print("Set elements:")
for num in IntegerSet {
    print(num)
}

Output:

Count of set elements is:  5
Set elements:
50
10
20
30
40

...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,
