Calculating Prime using sqrt in a for loop.

My code: 

for (var i = 3; i < sqrt(n); ++i) {
                    if (n! % i == 0) {
                        println("N is \(n)")
                    }

gives an error in XCode on the section i < sqrt(n);

"Cannot invoke ' < ' with an argument list of type '(@lvalue Int, $T4)'"

Can anyone help me understand what is going on here?

Hi Jason, from what i have read, to use the math-functions you have to import Cocoa.

Hmm... it's weird... That means my app has to be OS X based before I can import Cocoa. Kind of annoying.
