...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 classes Sample1 and Sample2. Both classes contain a method with the same name. And, we override the method using the override keyword and called the superclass method using the super keyword. Then we created the object child class Sample2 and called method and printed the messages on the console screen.
