why when ever I try to tap on my SKSpriteNode it is not interactive - ios

Question

I am trying to have my SKSpriteNode named "slots" be tapped on when ever a user is trying to hit a target in the middle of the sprite. But whenever I Tapp on the slot in does not blink or do anything really.
I was trying to have it blink and print("Tapped on shotSlotNode") before I'll go on to continue creating this game but im still struck on this part of the game.
var slots = [shotSlot]()
var targets = [shotSlot]()
var gameScore: SKLabelNode!
var slotsRed = [targetSlotRed]()
var shotSlotNode: shotSlot? // Define a property for shotSlotNode
override func didMove(to view: SKView) {
let backGround = SKSpriteNode(imageNamed: "background")
backGround.position = CGPoint(x: 512, y: 384)
backGround.blendMode = .replace
backGround.zPosition = -1
// line 20 makes sure things go on top of the background view.
backGround.scale(to: CGSizeMake(1024, 768))
// I used line 21 to strech the image out to fix my scrrens size because I know I set my screen size to 1024 in the GameScene UI
addChild(backGround)
gameScore = SKLabelNode(fontNamed: "Chalkduster")
gameScore.text = "Score: 0"
gameScore.position = CGPoint(x: 480, y: 70)
addChild(gameScore)
self.view?.isMultipleTouchEnabled = true

// this code breaks my slots into 3 rows and 3 cloumms of the shotSlots.
