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:)’
