Problem Solution:

Here, we will create an array of strings that contain the name of countries. Then we will access the name of countries from the array using the for in loop and also apply the where clause to filter the data.

Program/Source Code:

The source code to demonstrate the for in loop with the where clause is given below. The given program is compiled and executed successfully.

// Swift program to demonstrate the 
// "for in" loop with "where" clause.

import Swift;

let countries = ["INDIA", "USA", "UK", "CANADA"]

for country in countries where country != "UK" {
    print(country);
}

Output:

INDIA
USA
CANADA
