I’m attempting to add a shadow / glow effect to an SKLabelNode by using NSShadow, however I can’t get it to work, can someone tell me where I’m wrong in my code?

 var musicMenuText : NSAttributedString {

        let shadow = NSShadow()

        shadow.shadowBlurRadius = 5

        shadow.shadowColor = UIColor.white

//        shadow.shadowOffset = CGSize(width: 12, height: 12)

        let musicOn = UserDefaults.standard.bool(forKey: UDKeys.musicOn)

        let str1 = “Music ”

        let attrs1: [NSMutableAttributedString.Key: Any] = [

            .font: menuFont, .foregroundColor: UIColor.white]

        let attributedStr1 = NSMutableAttributedString(string: str1, attributes: attrs1)

        let str2 = “\(musicOn ? “On” : “Off”)”

        let attrs2: [NSAttributedString.Key: Any] = [

            .font: menuFont,

            .foregroundColor: musicOn ? UIColor.green : UIColor.red,

            .shadow: shadow

        ]

        let attributedStr2 = NSMutableAttributedString(string: str2, attributes: attrs2)

        attributedStr1.append(attributedStr2)

        return attributedStr1

    }

// Then I’m assigning the above to:

let menu3a = SKLabelNode(text: “Music”)

        menu3a.attributedText = musicMenuText

        menu3a.name = “Music”

        menu3a.position = CGPoint(x: frame.midX, y: frame.height * 0.30)

        addChild(menu3a)
