    func hex ( value : String, alpha : CGFloat) -> UIColor {
        var value = value
        let alpha = alpha
        var color: UInt32 = 0
        value = (value.replacingOccurrences(of: "#", with: ""))
        let scanner = Scanner(string: value)
        if scanner.scanHexInt32(&color) {
            let r = CGFloat((color & 0xFF0000) >> 16) / 255.0
            let g = CGFloat((color & 0x00FF00) >> 8) / 255.0
            let b = CGFloat(color & 0x0000FF) / 255.0
            return UIColor(red: r, green: g, blue: b, alpha: alpha)
        } else {
            print("Error. Not Found Colour.")
            return UIColor.black
        }
    }
    func yourFavoriteColorFromHex() -> UIColor{
        return self.hex(value: "1e90ff", alpha: 1.0)
    }

    /* RGB */
    func getColorFromRGB(value: UInt, alpha: CGFloat) -> UIColor {
        return UIColor(
            red: CGFloat((value & 0xFF0000) >> 16) / 255.0,
            green: CGFloat((value & 0x00FF00) >> 8) / 255.0,
            blue: CGFloat(value & 0x0000FF) / 255.0,
            alpha: CGFloat(alpha)
        )
    }

    func yourFavoriteColorFromRGB() -> UIColor{
        return self.getColorFromRGB(value: 0x9900FF, alpha: 1.0)
    }
}

How to use

label.textColor = UIColor().yourFavoriteColorFromHex()
label.backgroundColor = UIColor().yourFavoriteColorFromRGB()
