Does not animate on pressing animate button - ios

Question

Have an animation project which does not animate when I press the button. What am I doing wrong. Here is the code in the view controller:
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var startStopAnimating: UIButton!
#IBOutlet weak var imageView: UIImageView!
// image arrays
let frames: [String] = ["frame1.png", "frame2.png", "frame3.png", "frame4.png", "frame5.png", "frame6.png", "frame7.png"]
let swan: [String] = ["swanFrame1", "swanFrame2", "swanFrame3"]
let swirl: [String] = ["swirlFrame1", "swirlFrame2", "swirlFrame3"]
let starryNight: [String] = ["starryNight1", "starryNight2", "starryNight3"]
let doveWithBranch: [String] = ["doveWithBranch1", "doveWithBranch2", "doveWithBranch3"]
let tanCandles: [String] = ["tanCandles1", "tanCandles2", "tanCandles3", "tanCandles4"]
let buddhaFloat: [String] = ["buddhaFloat1", "buddhaFloat2", "buddhaFloat3", "buddhaFloat4", "buddhaFloat5", "buddhaFloat6"]
// timer vars
var timer = NSTimer()
var isAnimating = true
var counter = 1
var arrayIndex = 0
var pauseCheck = 0
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.

You're using pauseCheck as a selector but that's not a function in your code. I think you meant pauseCheckFunc?
Also I don't see anywhere in your code a command to actually start animating. You also don't properly set animation frames on your UIImages. It's unclear why you're using timers to animate images. You can just set an array of images to the animationImages property of your UIImages, and just use startAnimating() and stopAnimating() to start and stop animation.
