Why did we use this code:
switch downloadStatus {
case .Success(let success):
println(success)
case .Failure(let failure):
println(failure)
}
instead of an if statement with cases/else/returns?

9,575 Pointsi think switch reduces amount of code

2,793 PointsI'm fairly new and ignorant to programming concepts but would it be that Switch is the new if\else statement? Since with Switch we can do if/if-else/else without having to change our code if a new option comes up in the if statement.
As I said I may be way off but it seems the Switch is more dynamic in what you can do.

6,458 PointsSwitches exist alongside if-else statements. How you use them is your own convenience. In some cases switches may reduce the amount of code and make it more readable, in other cases it may look cumbersome and weird. There are minute differences, but I would say they only matter to a bit more advanced stuff, and by convenience even then.
I've always preferred if-else to switch. Switch is kinda like the foreign cousin of if-else, for and while, since it looks so different. Also, I vehemently hate the way you usually have to add a break-line for each case. Apparently in Swift breaking is no longer necessary, so I'm gonna have to reassess my prejudices :).
