let image = #imageLiteral(resourceName: "image.jpg")

let color = #colorLiteral(red: 0.9607843161, green: 0.7058823705, blue: 0.200000003, alpha: 1)

Triggering Examples

let image = ↓UIImage(named: "foo")

let color = ↓UIColor(red: 0.3, green: 0.3, blue: 0.3, alpha: 1)

let color = ↓UIColor(red: 100 / 255.0, green: 50 / 255.0, blue: 0, alpha: 1)

let color = ↓UIColor(white: 0.5, alpha: 1)

let image = ↓NSImage(named: "foo")

let color = ↓NSColor(red: 0.3, green: 0.3, blue: 0.3, alpha: 1)

let color = ↓NSColor(red: 100 / 255.0, green: 50 / 255.0, blue: 0, alpha: 1)

let color = ↓NSColor(white: 0.5, alpha: 1)

let image = ↓UIImage.init(named: "foo")

let color = ↓UIColor.init(red: 0.3, green: 0.3, blue: 0.3, alpha: 1)

let color = ↓UIColor.init(red: 100 / 255.0, green: 50 / 255.0, blue: 0, alpha: 1)

let color = ↓UIColor.init(white: 0.5, alpha: 1)
