CGFloat in Swift 2.0

After updating Swift to 2.0 I need to fix my code. Automatic correction doesn't work.

func getValueForKey(key: String) -> CGFloat {
        var inch = ""
        if screenSize.height == 480 {
            // iPhone 4, 4s and below
            inch = "3.5"
        } else if screenSize.height == 568 {
            // iPhone 5, 5s
            inch = "4"
        } else if screenSize.width == 375 {
            // iPhone 6
            inch = "4.7"
        } else if screenSize.width == 414 {
            // iPhone 6+
            inch = "5.5"
        } else if screenSize.width == 768 {
            // iPad
            inch = "5.5+"
        }
        let result = values["\(key)\(inch)"]!
        //        println("\(key) - \(result)")
        return result
    }

enter image description here

I have changed it. But nothing happens and it appears again!

How to fix it?

seems enough using: import CoreGraphics.

To elaborate on why importing UIKit fixes this problem:

The CGFloat struct is part of the CoreGraphics framework. UIKit by default imports Foundation which imports CoreGraphics.

If you weren't using UIKit or were on a platform that doesn't have the UIKit framework (such as Linux), Importing the Foundation module will import CoreGraphics.

The reason was absence of library UIKit.

import UIKit

This code before class has solved the problem.
