This is a known regression that is a fallout of the changes to playground 
literals, it is high priority to get fixed.

I agree, however, I like your workaround better than all the extra parentheses 
and CGFloats!

Wow, that's a ridiculous situation to have.  Who uses Float with iOS/tvOS 
anyway? 

I created a workaround, but I hate it:

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)
}
}

Re: [swift-users] Initializing a UIColor

[Dennis Weissmann via swift-users]

Huh! There’s a new overload for that initializer:



The one that takes CGFloats is the one that was there before, but the one 
taking Floats is new!

You can work around like this:

let color = UIColor(red: CGFloat(0.892), green: CGFloat(0.609), blue: 
CGFloat(0.048),  alpha: CGFloat(1.000))
or
let color = UIColor(red: Float(0.892), green: Float(0.609), blue: Float(0.048), 
 alpha: Float(1.000))

[swift-users] Initializing a UIColor

[Charles Lane via swift-users]

The following code worked fine in previous development snapshots but fails in 
the May 9, 2016 snapshot:

let color = UIColor(red: 0.892, green: 0.609, blue: 0.048,  alpha: 
1.000)

Does anyone know whether this is a bug or if the syntax changed? (Yes, I 
imported UIKit). Xcode gives an error of ‘Ambiguous use of 
init(red:green:blue:alpha:)’
