How to access custom properties from touched nodes when using an SKSpriteNode subclass?

So I created an SKSpriteNode subclass for my sprites. But whenever I retrieve the node(s) in the touched location (using nodes(at p: location), I can’t access the custom properties I that I had assigned to them earlier. Though I assume that’s because the retrieved node is of type SKSpriteNode as opposed to my custom type. So how would I go about either retrieving the node in my custom type or converting it to my custom type (while also retaining custom properties)?

Here's my subclass:

Code Block swift
class Gift: SKSpriteNode {
	var imageName: String
	var giftColor: Color
	init(imageName: String, giftColor: Color) {
		self.imageName = imageName
		self.giftColor = giftColor
		let texture = SKTexture(imageNamed: imageName)
		super.init(texture: texture, color: .clear, size: texture.size())
	}
	required init?(coder aDecoder: NSCoder) {
		fatalError("init(coder:) has not been implemented")
	}
}

Here's where I initialized the sprites:

Code Block swift
	func initializeGifts() {
		for i in 0...7 {
			var giftRow: [Gift] = []
			for j in 0...7 {
				let color = randomColor()                
				let x: Int = (115 + 77 * j) - Int(size.width) / 2
				let y: Int = -(205 + 85 * i) + Int(size.height) / 2
				giftRow.append(Gift(imageName: "gift_\(color.rawValue)", giftColor: color))
				giftRow[j].name = "\(color.rawValue)Gift"
				giftRow[j].position = CGPoint(x: x, y: y)
				giftRow[j].size = CGSize(width: 50, height: 58)
				addChild(giftRow[j])
			}
			gifts.append(giftRow) //`gifts` is a 2d array
		}
	}

And here's where I retrieved the nodes that were tapped:

Code Block swift
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
	guard let touch = touches.first else { return }
	let location = touch.location(in: self)
	let touchedNodes = nodes(at: location)
	for node in touchedNodes {
		print(node.giftColor) //Error: Value of type 'SKNode' has no member 'giftColor'
	}
}

Any help would be greatly appreciated!

Code Block 
    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        guard let touch = touches.first else { return }
        let location = touch.location(in: self)
        let touchedNodes = nodes(at: location)
        for node in touchedNodes {
            if let gift = node as? Gift { //<- Check if node is a Gift or not.
                print(gift.giftColor)
            }
        }
    }
