Variable names at the end

I am going through the new Apple Swift language.

Why should I use variable name at the end ?

var largest = 0
for (kind, numbers) in interestingNumbers {
    for number in numbers {
        if number > largest {
            largest = number
        }
    }
}
largest

If you are following the learning book (I see the code sample taken from the iBook) without Xcode; you are missing Xcode's Playground.

Download Xcode 6 Beta, open playground, paste above code, see the magic ;-)

Playground is a tool to see what happens in your code as you type.

Also to understand the philosophy behind Xcode Playground take a look at this video:

Are you asking why the last line is largest? Paste the code into a playground and you'll see it show the value of largest on the right at that line. It's just so you can see what the value is after the loop.
