How to set the background color in the safari app extension

I'm just starting out on my journey, but please don't swear too much. Can you please tell me how to set the desired background color for Custom View, the color I need is #F8F7F7.

Could you show the code ?

If your view is a UIView, (I call it theView):

        let hex = 0xF8F7F7                            // The hexadecimal value
        let r = CGFloat((hex >> 16) & 0xff) / 255     // Extract F8
        let g = CGFloat((hex >> 08) & 0xff) / 255     // Extract F7
        let b = CGFloat((hex >> 00) & 0xff) / 255     // Extract F7
        
        let color = UIColor(red: r, green: g, blue: b, alpha: 1)
        theView.backgroundColor = color
