Load gif into WKwebView and integrate interval timer.... uikit. Thanks - ios

Question

I am beginner so please take in advance. I am trying to show some gifs up on eby one i got in the assets folder, so i do not know how to display and put time through in those pics, because i have already got the way to show the wkwebview but i cannot get gif into WKwebView one by one with intervals among them.
Here is the code:
import UIKit
import WebKit
class SecondWebKitView: UIViewController {
#IBOutlet weak var timeLabel: UILabel!
#IBOutlet weak var descriptionLabel: UILabel!
#IBOutlet weak var titleLabel: UILabel!
#IBOutlet weak var greyView: UIView!
#IBOutlet weak var webKitView: WKWebView!
let totalCount = 13
var count = 1
var myTimer = Timer()
override func viewDidLoad() {
super.viewDidLoad()
greyView.layer.cornerRadius = 10
let url = Bundle.main.url(forResource: "1.JumpingJacks", withExtension: "gif")!
let data = try! Data(contentsOf: url)
webKitView.load(data, mimeType: "image/gif", characterEncodingName: "UTF-8", baseURL: NSURL() as URL)
webKitView.scalesLargeContentImage = true
webKitView.contentMode = UIView.ContentMode.scaleAspectFit
let jsonUrlString = "https://fitness-db.p.rapidapi.com/7-minute-workout"
guard let url = URL(string: jsonUrlString) else {return}
URLSession.shared.dataTask(with: url) { (data, response, err) in
guard let data = data else {return}
do {
let websiteDescription = try JSONDecoder().decode(SecondWebKitModel.self, from: data)
print(websiteDescription.description ?? "", websiteDescription.description ?? "", websiteDescription.title ?? "")
//let courses = try JSONDecoder().decode([Course].self, from: data)
DispatchQueue.main.async {
self.descriptionLabel.text = websiteDescription.description
}
} catch let jsonErr {
print("Error serializing json", jsonErr)
}
}.resume()
}
#IBAction func start(sender: AnyObject) {
myTimer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: Selector(("myPerformeCode:")), userInfo: nil, repeats: true)
}
func myPerformeCode(timer : Timer) {
print("Displayed")
count += 1
if count < totalCount {
let filePath = Bundle.main.path(forResource: "\(count)", ofType: "gif")
let gif = NSData(contentsOfFile: filePath!)
self.webKitView.load(gif! as Data, mimeType: "image/gif",characterEncodingName: String(), baseURL: NSURL() as URL)
self.webKitView.isUserInteractionEnabled = false
} else {
count = 1
}
}
}
Need to solve how to show gifs up with timing. Thanks
