Crash for white color

[Saad El Oulladi]

Hello,
Thank you for this nice lib.
I'm getting a crash when selecting white color.

open var blueValue: CGFloat{ return cgColor.components! [2] }

Fatal error: Index out of range ;)

I avoided a same problem as follows.
MKColorPicker.allColors.append(UIColor.hex("#FFFFFF", alpha: 1.0))

UIColor extension is here.

extension UIColor {
    class func hex ( _ hexStr : String, alpha : CGFloat) -> UIColor {
        var hexString = hexStr as NSString

        hexString = hexString.replacingOccurrences(of: "#", with: "") as NSString
        let scanner = Scanner(string: hexString as String)
        var color: UInt32 = 0
        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("invalid hex string")
            return UIColor.clear;
        }
    }
}
