• SR-1430 Swift 3 no longer automatically coerces Double literal argument to CGFloat

Issue Description:

Discovered on the Swift-User list that UIColor in the most recent May 3rd toolchain supports initializers for both Float and CGFloat. Which is odd: Bit of a problem because Xcode complains about an “Ambiguous use of init(red:green:blue:alpha🙂”. No kidding. So right now, you have to cast everything, e.g.

let color = UIColor(red: CGFloat(0.5), green: CGFloat(0.5), blue: CGFloat(0.5), alpha: CGFloat(1.0))

Or you can do something really stupid like this:

{{extension Double {
var cg: CGFloat { return CGFloat(self) }
}

class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let c = UIColor(red: 0.5.cg, green: 0.5, blue: 0.5, alpha: 0.5)
}
}}}
It works but ew. Who ever uses Float with UIColor to begin with and why did this pop up in the latest build? Is it part of the Cocoa auto-migration thing?

Can you please take it out? Thanks.
