How to ask for in "output" to enter a variable value.(Like Scanner class in Java)

As I am learning through Swift, I can't help but compare whatever little bit that I have learned in Java. I had one specific question: while going through this tutorials, a value is already assigned to a variable. ex: var height = 23

Can't you have something in Swift where it can ask in the output to enter a value for the variable. So instead of assigning the value 23 to the variable height, I want to ask in the output for the user to enter the value, whichever number he wants.. How can you do that in Swift?
