What does (success) and (failure) actually pertain to?

I'm a bit confused by one bit of the code used in this exercise.

This is the bit I am confused by: case .Success(let success): println(success)

What is actually going on in this portion of the code? What do the (success) and (failure) parts mean?

What I understood from the video :

This lets you define a constant to which the associated value will be assigned.

case .Success(let success):

So if you decide to print the value, now you can

println(success)
