How to convert Color Literal to cgColor in the Swift?

var CodeBackground = #colorLiteral(red: 0.1294117647, green: 0.1294117647, blue: 0.1960784314, alpha: 1)

cells?.layer.borderColor = //... how can i set this color literal to cgColor?

As I know how to convert that UIColor to cgColor in the Swift

as example

UIColor.black.cgColor

Bingo, but what about Color Literal to cgColor in the Swift

Thank you.

Solution

As, You already know the simpler way of using colorLiteral as cgcolor, I'll jump to the other way of doing that...

For that you need a Custom Function which gets the color-value(red , green , blue) from the colorLiteral , which is as below

extension UIColor {
    func rgb() -> (red:Int, green:Int, blue:Int, alpha:Int)? {
    var fRed : CGFloat = 0
    var fGreen : CGFloat = 0
    var fBlue : CGFloat = 0
    var fAlpha: CGFloat = 0
    if self.getRed(&fRed, green: &fGreen, blue: &fBlue, alpha: &fAlpha) {
        let iRed = Int(fRed * 255.0)
        let iGreen = Int(fGreen * 255.0)
        let iBlue = Int(fBlue * 255.0)
        let iAlpha = Int(fAlpha)

        _ = (iAlpha << 24) + (iRed << 16) + (iGreen << 8) + iBlue
        return (red:iRed, green:iGreen, blue:iBlue, alpha:iAlpha)
    } else {
        // Could not extract RGBA components:
        return nil
    }
}
}
//It's more convenient to use function in `UIColor` extension

Now , after this function created you can convert colorliteral into cgColor as below...

let CodeBackground = #colorLiteral(red: 0.1294117647, green: 0.1294117647, blue: 0.1960784314, alpha: 1)
let rgblit = CodeBackground.rgb()
let Converted_cgColor = CGColor(srgbRed: CGFloat(integerLiteral: rgblit!.red), green: CGFloat(integerLiteral: rgblit!.green), blue: CGFloat(integerLiteral: rgblit!.blue), alpha: CGFloat(integerLiteral: rgblit!.alpha))

You can directly use Converted_cgColor like

cells?.layer.borderColor = Converted_cgColor
