solution

1.  Use source code to remove error

2. Update your library pod

example i use fspagerview and update

 pod 'FSPagerView', '~> 0.7'
update to pod 'FSPagerView', '~> 0.7.1'

   The viewForHeaderInSection method belongs to the UITableViewDelegate Protocol. You therefore must set the delegate of your table view to your view controller in order to get this callback. You probably did just set the tableview's dataSource as your other methods are called.

and this example full code without xib file. :)

import UIKit

class HeaderTableViewController: UITableViewController {

    let sectionNames = [ "iPhone", "iPad", "Apple Watch", "Apple Watch" ]
     let sectionItems = [["iPhone 5", "iPhone 5s", "iPhone 6", "iPhone 6 Plus", "iPhone 7", "iPhone 7 Plus"],
    ["iPad Mini", "iPad Air 2", "iPad Pro", "iPad Pro 9.7"],
    ["Apple Watch", "Apple Watch 2", "Apple Watch 2 (Nike)"]]

    
    override func viewDidLoad() {
        super.viewDidLoad()
        navigationItem.title = "Apple Product"
        navigationController?.navigationBar.prefersLargeTitles = true
        tableView.register(UINib(nibName: "ApiTableViewCell", bundle: nil), forCellReuseIdentifier: "cell")

    }
    
    override func numberOfSections(in tableView: UITableView) -> Int {
        return self.sectionItems.count
    }
    
    override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {

        let cell = tableView.dequeueReusableCell(withIdentifier: "cell") as? ApiTableViewCell
        cell?.merkLabel.text = self.sectionNames[section]
        return cell
    }
    
    override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
        return 34
    }
    
    
    
    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return self.sectionItems[section].name.count
        
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! ApiTableViewCell
        let name = self.sectionItems[indexPath.section].name[indexPath.row]
        cell.merkLabel.text = name
        
        return cell
    }

}

This time i will give an example for Auto Slide Page, and will use FSPagerView for slider and
Kingfisher as image

here's an example code:

1.   input UiView then select to costum class FSPagerView ,  and than

- will then look like this






2. Full Code

import UIKit
import Kingfisher
import FSPagerView

class AutoSlideViewController: UIViewController, FSPagerViewDataSource, FSPagerViewDelegate {
   
    @IBOutlet weak var viewBanner: FSPagerView! {
        didSet {
            self.viewBanner.register(FSPagerViewCell.self, forCellWithReuseIdentifier: "cell")
            self.viewBanner.transformer = FSPagerViewTransformer(type: .linear)
            self.viewBanner.itemSize = CGSize(width: 300, height: 150)
            self.viewBanner.isInfinite = true
            self.viewBanner.contentMode = .scaleAspectFit
            self.viewBanner.backgroundColor = #colorLiteral(red: 1.0, green: 1.0, blue: 1.0, alpha: 1.0)
            self.viewBanner.automaticSlidingInterval = 3.0
        }
    }
    @IBOutlet weak var pageC: UIPageControl!
    

    var arrayImageFisher = ["data1.jpg, data2.jpg, data3.jpg"]
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        self.pageC.hidesForSinglePage = true
    
    }
    
  
    
    func numberOfItems(in pagerView: FSPagerView) -> Int {
        self.pageC.numberOfPages = self.arrayImageFisher.count
        return self.arrayImageFisher.count
    }
    
    func pagerView(_ pagerView: FSPagerView, cellForItemAt index: Int) -> FSPagerViewCell {
        let cell = pagerView.dequeueReusableCell(withReuseIdentifier: "cell", at: index)
        
        let resource = ImageResource(downloadURL: URL(string: arrayImageFisher[index])!)
        
        cell.imageView?.kf.setImage(with: resource)
        cell.imageView?.contentMode = .scaleAspectFill
        cell.imageView?.clipsToBounds = true
        self.pageC.currentPage = index
        return cell
    }
    
    
    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        let page = scrollView.contentOffset.x / scrollView.frame.width
        pageC.currentPage = Int(page)
        
    }
    

}

Super easy to implement page view controller with indicator bar slide controllers Tabman

Install pod :

pod 'Tabman'


how to use :

1. Use simultaneously PageBoy and Tabman

import Pageboy
import Tabman

simple use

class YourTabViewController: TabmanViewController,  PageboyViewControllerDataSource
  var viewControllers: [UIViewController] = [
        ViewController1(),
        ViewController2(),
    ] 

override func viewDidLoad() {
  super.viewDidLoad()

  self.dataSource = self

         // configure the bar
         self.bar.items = [Item(title: "Page 1"),
                             Item(title: "Page 2")]
 }
}

  func numberOfViewControllers(in pageboyViewController: PageboyViewController) -> Int {
        return self.viewControllers.count
    }
    
    func viewController(for pageboyViewController: PageboyViewController, at index: PageboyViewController.PageIndex) -> UIViewController? {
        return self.viewControllers[index]
    }
    
    func defaultPage(for pageboyViewController: PageboyViewController) ->
        PageboyViewController.Page? {
        return nil
    }

2. Full Code swift file

import Pageboy
import Tabman
import UIKit

class YourTabViewController: TabmanViewController {
    var viewControllers: [UIViewController] = [
        ViewController1(),
        ViewController2(),
        ViewController3(),
        ViewController4(),
        ViewController5(),
        ViewController6()
    ]
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        self.navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: .plain, target: nil, action: nil)
        navigationItem.backBarButtonItem?.tintColor = #colorLiteral(red: 0.5704585314, green: 0.5704723597, blue: 0.5704649091, alpha: 1)
        self.title = "Cari Asuransi"
        self.dataSource = self
        
        self.bar.items = [
            Item(title: "Item1"),
            Item(title: "Item2"),
            Item(title: "Item3"),
            Item(title: "Item4"),
            Item(title: "Item5"),
            Item(title: "Item6")
        ]
        
        self.bar.style = . scrollingButtonBar  
        self.bar.appearance = TabmanBar.Appearance({ appearance in
            
            appearance.indicator.color = #colorLiteral(red: 0, green: 0, blue: 0, alpha: 1)
            appearance.indicator.lineWeight = .normal
            appearance.indicator.compresses = true
            
            appearance.text.font = UIFont.systemFont(ofSize: 12.0, weight: .medium)
            
            appearance.layout.height = .explicit(value: 5.0)
            appearance.layout.interItemSpacing = 15.0
            
        })
        view.backgroundColor = #colorLiteral(red: 1.0, green: 1.0, blue: 1.0, alpha: 1.0)
        navigationController?.navigationBar.barTintColor = UIColor.green
        self.doSomething()
    }
    
}

extension YourTabViewController: PageboyViewControllerDataSource {
    func numberOfViewControllers(in pageboyViewController: PageboyViewController) -> Int {
        return self.viewControllers.count
    }
    
    func viewController(for pageboyViewController: PageboyViewController, at index: PageboyViewController.PageIndex) -> UIViewController? {
        return self.viewControllers[index]
    }
    
    func defaultPage(for pageboyViewController: PageboyViewController) ->
        PageboyViewController.Page? {
        return nil
    }
}

Update :

if you want use collectionview click per cell (collectionviewcell) in firstViewController and in secondController use Tabman add this in your program :

- In FirstController

 func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
        self.colectinView1?.scrollToItem(at: IndexPath(row: 0, section: 0), at: .top, animated: true)
        

if collectionView == self.colectionView {
            let vc1 = YourTabViewController()
            
            switch indexPath.row {
            case 0:
                self.navigationController?.pushViewController(vc1, animated: true)
            case 1:
                self.navigationController?.pushViewController(vc1, animated: true)
                vc1.itemSelectIndex = 1
            case 2:
                self.navigationController?.pushViewController(vc1, animated: true)
                vc1.itemSelectIndex = 2
            case 3:
                self.navigationController?.pushViewController(vc1, animated: true)
                vc1.itemSelectIndex = 3
                
            default:
                break
            }
            return }

}

 - add this code In your Tabman (secondController)

 var itemSelectIndex = Int()

 override func viewDidLoad() {
        super.viewDidLoad()
        
        doSomething()        
        ....
        
        }

func doSomething() {
        if self.itemSelectIndex == 1 {
            scrollToPage(.at(index: 1), animated: true)
        }
        if self.itemSelectIndex == 2 {
            scrollToPage(.at(index: 2), animated: true)
        }
        if self.itemSelectIndex == 3 {
            scrollToPage(.at(index: 3), animated: true)
        }
    }

This time, I’ve created a simple app that demonstrates the use of NSNotifcationCenter so that we can better understand what this would look like in code, and how it actually works. If you’re like me and you’re a hands on type of learner — feel free to code along.

1. Layout in xib file



2. Full Code swift file

import UIKit
import UserNotifications

class NotificationViewController: UIViewController {

    @IBOutlet weak var tabelView: UITableView!
    let koo = "You Get Notification Coy"
    var users = [String]()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        tabelView.delegate = self
        tabelView.dataSource = self
        tabelView.register(UINib(nibName: "ApiTableViewCell", bundle: nil), forCellReuseIdentifier: "cell")
        tabelView.tableFooterView = UIView(frame: CGRect.zero)

        UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { (succes, error) in
            if error != nil {
                print("Unsusses")
            } else {
                print("succesful")
            }
        }
    }
    @IBAction func bNotif(_ sender: UIButton) {
        self.users.append(self.koo)
        tabelView.beginUpdates()
        let indexPath = IndexPath(row: users.count - 1, section: 0)
        tabelView.insertRows(at: [indexPath], with: .automatic)
        tabelView.endUpdates()
        
        view.endEditing(true)
        timedNotification(inSecond: 1) { (success) in
            if success {
                print("it's success notif")
                
            }
        }
    }
    
    func timedNotification(inSecond: TimeInterval, complition: @escaping (_ Success: Bool) -> ()) {
        
        let trigger = UNTimeIntervalNotificationTrigger(timeInterval: inSecond, repeats: false)
        let content = UNMutableNotificationContent()
        
        content.title = "You Have Notification"
        content.subtitle = "Ok you succes learn this in the weekend"

    func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
        
        if editingStyle == .delete {
            users.remove(at: indexPath.row)
            tableView.beginUpdates()
            tableView.deleteRows(at: [indexPath], with: .automatic)
            tableView.endUpdates()
        }
    }
}

This time i share how to make UITabBarController condition IF and ElSE data you get have 2 or more.

1. you must create new file swift in cocoa touch class adn create UItabbarViewController, example HomeTabBarController.swift

import UIKit

class HomeTabBarController: UITabBarController {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        

      }
  }

2. example in apliacetion.

        
    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(true)
        DispatchQueue.main.async {
            NetworkService<HomePembelianEntity>.process(client: NetworkClient(endPont: .pembelianHome), onSuccess: { dataPembeli in
                self.dataBeli = dataPembeli
                
                if self.dataBeli?.data?.count == 0 {
                    let berandaVc = HomeViewController()
                    let profilVc = ProfilViewController()
                    let pembelianVc = PembelianKosongViewController()
                    let klaimVc = KlaimKosongViewController() // sementara
                    let pengaturanVC = SettingViewController()
                    
                    berandaVc.tabBarItem.title = "Beranda"
                    profilVc.tabBarItem.title = "Profil"
                    pembelianVc.tabBarItem.title = "Pembelian"
                    klaimVc.tabBarItem.title = "Klaim"
                    pengaturanVC.tabBarItem.title = "Pengaturan"
                    
                    berandaVc.tabBarItem.image = UIImage(named: "beranda.png")
                    profilVc.tabBarItem.image = UIImage(named: "profil.png")
                    pembelianVc.tabBarItem.image = UIImage(named: "pembelian.png")
                    klaimVc.tabBarItem.image = UIImage(named: "klaim.png")
                    pengaturanVC.tabBarItem.image = UIImage(named: "pengaturan.png")
                    
                    
                    self.viewControllers = [berandaVc, profilVc, pembelianVc, klaimVc, pengaturanVC]
                    
                } else {
                    let berandaVc = HomeViewController()
                    let profilVc = ProfilViewController()
                    let pembelianVc = PembelianViewController()
                    let klaimVc = KlaimKosongViewController() // sementara
                    let pengaturanVC = SettingViewController()
                    
                    berandaVc.tabBarItem.title = "Beranda"
                    profilVc.tabBarItem.title = "Profil"
                    pembelianVc.tabBarItem.title = "Pembelian"
                    klaimVc.tabBarItem.title = "Klaim"
                    pengaturanVC.tabBarItem.title = "Pengaturan"
                    
                    berandaVc.tabBarItem.image = UIImage(named: "beranda.png")
                    profilVc.tabBarItem.image = UIImage(named: "profil.png")
                    pembelianVc.tabBarItem.image = UIImage(named: "pembelian.png")
                    klaimVc.tabBarItem.image = UIImage(named: "klaim.png")
                    pengaturanVC.tabBarItem.image = UIImage(named: "pengaturan.png")
                    
                    
                    self.viewControllers = [berandaVc, profilVc, pembelianVc, klaimVc, pengaturanVC]
                }
                
            }, onFailure: nil)
        }
    }

You can use UserDefaults, in viewController

UserDefaults.standard.set(loginTextField.text, forKey: "login")

 @IBAction func login(_ sender: Any) {
        UserDefaults.standard.set(loginTextField.text, forKey: "login")
          let vc = HomeViewController()
            navigationController?.pushViewController(vc, animated: true)
}

I do this in my AppDelegate, my initial view controller assumes that my user is logged in. Thus, in my AppDelegate I do the following to decide whether I need to show the login screen:

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        
        var route = UIViewController()
        if UserDefaults.standard.string(forKey: "token") != nil {
            route = HomeViewController()
        } else {
            route = OnBoardingViewController()
        }
        
        window = UIWindow(frame: UIScreen.main.bounds)
        window?.makeKeyAndVisible()
        window?.rootViewController = UINavigationController(rootViewController: route)
        
        
        return true
    }

var List: [String] = [""]

var sum = 0

sum += Int(textIsi.text!)! Like this

List.append(textIsi.text!)
sum += Int(textIsi.text!)! 
labelRp.text = "\(sum)"

import UIKit

class InAndDelRowViewController: UIViewController {
    @IBOutlet weak var labelRp: UILabel!
    @IBOutlet weak var textIsi: UITextField!
    @IBOutlet weak var bAdd: UIButton!
    @IBOutlet weak var tblView: UITableView!
    
    var List: [String] = [""]
    var sum = 0
    
    override func viewDidLoad() {
        super.viewDidLoad()
        self.tblView.delegate = self
        self.tblView.dataSource = self
        self.tblView.rowHeight = UITableViewAutomaticDimension
        self.tblView.estimatedRowHeight = 100.0
        self.tblView.separatorInset = UIEdgeInsetsMake(0, UIScreen.main.bounds.width, 0, 0)
        self.tblView.register(UINib(nibName: "InDelTableViewCell", bundle: nil), forCellReuseIdentifier: "cell")
        
        //membuat tabel bawah kosong (tabel ada klw ada data)
        tblView.tableFooterView = UIView(frame: CGRect.zero)
        
        

    }

    @IBAction func bAddAction(_ sender: UIButton) {
        print(self.List)
        insertNewVTitle()
    }
    func insertNewVTitle() {
        
        List.append(textIsi.text!)
        sum += Int(textIsi.text!)!
        labelRp.text = "\(sum)"
        
        let indexPath = IndexPath(row: List.count - 1, section: 0)
        
        tblView.beginUpdates()
        tblView.insertRows(at: [indexPath], with: .automatic)
        tblView.endUpdates()
        
        textIsi.text = ""
        view.endEditing(true)
    }
    
    
}

extension InAndDelRowViewController: UITableViewDelegate, UITableViewDataSource {

        let Title = List[indexPath.row]
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! InDelTableViewCell
        cell.labelTest.text = Title
     
        return cell
    }
    
    //for edit
    func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
        return true
    }
    
    func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
        
        if editingStyle == .delete {
            List.remove(at: indexPath.row)
            tableView.beginUpdates()
            tableView.deleteRows(at: [indexPath], with: .automatic)
            tableView.endUpdates()
        }
    }
    
    
}

Here is example code :

1.  TextDidEndEditing (after you end editing text)

 import UIKit
import Alamofire
import SwiftyJson
 
class autoTextViewController: UIViewController, UITextFieldDelegate {
 
    
    @IBOutlet weak var txt1: UITextField!
    @IBOutlet weak var txt2: UITextField!
    @IBOutlet weak var txt3: UITextField!
    
    let myArray = "String1"
    let myArray2 = "String2"
 
    
    override func viewDidLoad() {
        super.viewDidLoad()
    
         txt1.delegate = self
        txt2.delegate = self
        txt3.delegate = self
        
        
        txt1.resignFirstResponder() // to respon text end editing

       
    }
   func textFieldDidEndEditing(_ textField: UITextField) {
        DispatchQueue.main.async {
            NetworkService<WowMobilJenisEntity>.process(client: NetworkClient(endPont: .jenisMobil(mobilId: self.merkIdM)), onSuccess: { dataJ in
                var data: [PickerDataSource] = []
                self.txt2.text = dataJ.data?.first?.jenis ?? ""
            }, onFailure: nil)
        
        
            self.txt3.text = self.myArray2
        }     
     }

    }

2. Use In API  (This exaple use Post and GET data)

import UIKit

class autoTextViewController: UIViewController, UITextFieldDelegate {
 
    
    @IBOutlet weak var txt1: UITextField!
    @IBOutlet weak var txt2: UITextField!
    
  
    var merkIdM: Int = 0
    var tipeId: Int = 0
    
    enum FieldType {
        case merk, tipe
    }
    var fieldType: FieldType = .merk
    
    override func viewDidLoad() {
        super.viewDidLoad()
    
         txt1.delegate = self
        txt2.delegate = self
    
        
        txt1.resignFirstResponder()

       
    }
   
    
   
    @IBAction func txt1DidEnd(_ sender: UITextField) {
        self.fieldType = .merk 
      let param = ["dataSend": txt1.text]
       Alamofire.request("Url", method: .post, parameters: param, encoding: URLEncoding.queryString, headers: nil)
            .responseJSON { response in
                switch response.result {
                case .success(let value):
                    
                case .failure:
                    print("Error")
                }
            }        
    }
    
    @IBAction func txt2DidEnd(_ sender: UITextField) {
        self.fieldType = .tipe
        sender.resignFirstResponder() 
     
             
    }
    
    func textFieldDidEndEditing(_ textField: UITextField) {
       
      var tipe: String?

         init(json: JSON) {
          self.id = json["tipe"].string
       
       }
 
           Alamofire.request("Url", method: .get, parameters: nil, encoding: URLEncoding.queryString, headers: nil)
            .responseJSON { response in
                switch response.result {
                case .success(let value):
                     self.txt2.text = value.data?.first?.tipe ?? ""
                case .failure:
                    print("Error")
                }
            }  
    
   }
    

}

extension autoTextViewController: CustomPickerDelegate {
    func didSelect(data: PickerDataSource?) {
        switch self.fieldType {
        case .merek:
            self.merkView.isiLabel.text = data?.name ?? ""
            self.merkIdM = Int(data?.id ?? "0")!
       
            
        case .jenis:
            self.txt2.text = data?.name ?? ""
            self.tipeId = Int(data?.id ?? "0")!
            
     
        }
    }
}

This is how to create animation with cocoapod library, ok I will give an example with library AnimatedTextInput . 

Use cocoapods to install this custom control in your project.

pod 'AnimatedTextInput'

how to use it is quite easy,  see the coding below

import UIKit
import AnimatedTextInput

class TextInputViewController: UIViewController {
    @IBOutlet weak var labelT: UILabel!
    @IBOutlet weak var textAnimate: AnimatedTextInput!
    
    
    override func viewDidLoad() {
        super.viewDidLoad()
        textAnimate.placeHolderText = "Paswword"
        textAnimate.style = CustomTextInputStyle()
        textAnimate.type = .password(toggleable: true)
    }

}

struct CustomTextInputStyle: AnimatedTextInputStyle {
    let placeholderInactiveColor = UIColor.gray
    let activeColor = #colorLiteral(red: 0.4588235294, green: 0.7176470588, blue: 0.1803921569, alpha: 1)
    let inactiveColor = UIColor.gray.withAlphaComponent(0.3)
    let lineInactiveColor = UIColor.gray.withAlphaComponent(0.3)
    let lineActiveColor = UIColor.gray.withAlphaComponent(0.3)
    let lineHeight: CGFloat = 1
    let errorColor = UIColor.red
    let textInputFont = UIFont.systemFont(ofSize: 14)
    let textInputFontColor = UIColor.black
    let placeholderMinFontSize: CGFloat = 12
    let counterLabelFont: UIFont? = UIFont.systemFont(ofSize: 12)
    let leftMargin: CGFloat = 0
    let topMargin: CGFloat = 20
    let rightMargin: CGFloat = 0
    let bottomMargin: CGFloat = 10
    let yHintPositionOffset: CGFloat = 7
    let yPlaceholderPositionOffset: CGFloat = 0
    public let textAttributes: [String: Any]? = nil
}

How to Use more than one json file in library animation LOTTIE.

this example for 3 json file animation.

Note: use UICollectionview & UICollectionViewCell

import UIKit
import Lottie

class LoViewController: UIViewController {
    @IBOutlet weak var viewColCell: UIView!
    @IBOutlet weak var pageCon: UIPageControl!
    @IBOutlet weak var collView: UICollectionView!
    let animationIntro1 = LOTAnimationView(name: "intro-1") //json 1
    let animationIntro2 = LOTAnimationView(name: "intro-2") //json 2
    let animationIntro3 = LOTAnimationView(name: "intro-3") //json 3
    
    override func viewDidLoad() {
        super.viewDidLoad()
        setConponent()
        collView.backgroundColor = UIColor.clear
        
        //animation 1
        animationIntro1.frame = CGRect(x: 0, y: 50, width: self.viewColCell.frame.size.width, height: 300)
        animationIntro1.contentMode = .scaleAspectFill
        animationIntro1.loopAnimation = false
        
        //animation 2
        animationIntro2.frame = CGRect(x: 0, y: 50, width: self.viewColCell.frame.size.width, height: 300)
        animationIntro2.contentMode = .scaleAspectFill
        animationIntro2.loopAnimation = false
        
        //animation 3
        animationIntro3.frame = CGRect(x: 0, y: 50, width: self.viewColCell.frame.size.width, height: 300)
        animationIntro3.contentMode = .scaleAspectFill
        animationIntro3.loopAnimation = false
        
        self.viewColCell.addSubview(animationIntro1)
        self.viewColCell.addSubview(animationIntro2)
        self.viewColCell.addSubview(animationIntro3)
        
        animationIntro1.play()
        animationIntro2.isHidden = true
        animationIntro3.isHidden = true
        
    }
    
    func setConponent() {
        self.collView.dataSource = self
        self.collView.delegate = self
        self.collView.register(UINib(nibName: "CollectionViewCell", bundle: nil), forCellWithReuseIdentifier: "cell1")
        
        
        self.pageCon.hidesForSinglePage = true
    }
    
    func collectionView(_ collectionView: UICollectionView, willDisplay cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {
        self.pageCon.currentPage = indexPath.section
    }
    
    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        let page = scrollView.contentOffset.x / scrollView.frame.width
        pageCon.currentPage = Int(page)
        
        
        if page == 0 {
            animationIntro1.play()
            animationIntro1.isHidden = false
            animationIntro2.isHidden = true
            animationIntro3.isHidden = true
            
        } else if page == 1 {
            animationIntro2.play()
            animationIntro1.isHidden = true
            animationIntro2.isHidden = false
            animationIntro3.isHidden = true
            
        } else if page == 2 {
            animationIntro3.play()
            animationIntro1.isHidden = true
            animationIntro2.isHidden = true
            animationIntro3.isHidden = false
        }
    }
    
}
