swift compile error due to class extension

I have been working on a project and everything seemed to work fine. I have added the following class extension:

extension CGFloat {
static func random() -> CGFloat {
    return CGFloat(Float(arc4random()) / Float(UInt32.max))
}
static func random(#min: CGFloat, max: CGFloat) -> CGFloat {
    assert(min < max)
    return CGFloat.random() * (max - min) + min
}
}

And I suddenly got 21 errors. The screen shot is below. enter image description here

Anyone knows how to solve this?

EDIT:

I managed to solve the problem, which apparently was that I should import UIKit above everything else. Now I still have a problem, that the app runs fine on a simulator but does not work on real device. It says that there is segmentation fault: 11, and that it cant build obj-c module UIKit.

Ok I managed to solve it: All I needed to do was to reduce my deployment target from 8.3 to 8. No idea why this is the case though.

In the case adding UIKit started making things work. Could it be as simple as adding...

import Foundation

on the top would make it work?
