Why can't the method be called? - ios

Question

I just cloned a project from GitHub, and I added the relevant folder to my project. When I run my project, the animation effect can be displayed normally, but the images on the animation can't be displayed. I have tried re-cloning the complete code, but it still does the same. I'm sure that all the codes and images are completely cloned.
I added a breakpoint, realizing that the func circleMenu is never called.
Can someone please explain this, or at least tell me what I need to write to get it correct?
Here is my code:
import UIKit
import CircleMenu
extension UIColor {
static func color(_ red: Int, green: Int, blue: Int, alpha: Float) -> UIColor {
return UIColor(
red: 1.0 / 255.0 * CGFloat(red),
green: 1.0 / 255.0 * CGFloat(green),
blue: 1.0 / 255.0 * CGFloat(blue),
alpha: CGFloat(alpha))
}
}
class FirstViewController: UIViewController, CircleMenuDelegate,UIImagePickerControllerDelegate,UINavigationControllerDelegate{
#IBAction func to2(_ sender: UIButton) {
let sb = UIStoryboard(name:"Main",bundle: Bundle.main)
let view2 = sb.instantiateViewController(withIdentifier: "view2")
layerTransition(animTye: .cube, subType: .ramdom, curve: .EaseInEaseOut, duration: 0.4, layer: (self.view.window?.layer)!)
self.present(view2,animated: true,completion: nil)
}
// let secondView = ViewController()
#IBAction func toView2(_ sender: UIButton) {
let sb = UIStoryboard(name:"Main",bundle: Bundle.main)
let secondViewController = sb.instantiateViewController(withIdentifier: "SecondViewController")
layerTransition(animTye: .cube, subType: .ramdom, curve: .EaseInEaseOut, duration: 0.4, layer: (self.view.window?.layer)!)
self.present(secondViewController,animated: true,completion: nil)

At this moment you only declare your delegate. Make sure you also set the delegate otherwise your delegate methodes wouldn't be called.
