Cant go back to original ViewController with .left swipe? - swift

Question

I have a viewcontroller that is embedded in a navigation controller. I wanted a Swipe right to go right left and change viewcontroller from VC1 to VC2, which thanks to people on stackoverflow i managed to do. However now i want to go the traditional way left right (traditional way for push), when swiping left on VC2 that goes back to VC1.
This is my code in VC1 (to swipe right to go to VC2):
override func viewDidLoad() {
super.viewDidLoad()
//Swipe right gesture
let gesture = UISwipeGestureRecognizer(target: self, action: #selector(SelectedTopicViewController.performChange))
gesture.direction = .right
self.view.addGestureRecognizer(gesture)
}
#objc func performChange() {
self.performSegue(withIdentifier: "goTo", sender: nil)
}
This is my code in VC2 (for swiping left to go back to VC1):
override func viewDidLoad() {
super.viewDidLoad()
self.navigationController?.setNavigationBarHidden(true, animated: false)
//swipe left gesture
let gesture = UISwipeGestureRecognizer(target: self, action: #selector(SendMessageTopicViewController.performChange))
gesture.direction = .left
self.view.addGestureRecognizer(gesture)
// Do any additional setup after loading the view.
}
#objc func performChange() {
//self.navigationController?.popViewController(animated: true)
//print("swipe detected")
self.performSegue(withIdentifier: "goBackToRight", sender: nil)
}
Also this is my custom segue code (for both left and right swipe):
import Foundation
import UIKit
import QuartzCore
class SegueFromLeft: UIStoryboardSegue {
override func perform() {
let src: UIViewController = self.source
let dst: UIViewController = self.destination
let transition: CATransition = CATransition()
let timeFunc : CAMediaTimingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.duration = 0.25
transition.timingFunction = timeFunc
transition.type = kCATransitionPush
transition.subtype = kCATransitionFromLeft
src.navigationController!.view.layer.add(transition, forKey: kCATransition)
src.navigationController!.pushViewController(dst, animated: false)
}
}
class SegueFromRight: UIStoryboardSegue {
override func perform() {
let src = self.source
let dst = self.destination
src.view.superview?.insertSubview(dst.view, aboveSubview: src.view)
dst.view.transform = CGAffineTransform(translationX: src.view.frame.size.width*2, y: 0) //Double the X-Axis
UIView.animate(withDuration: 0.25, delay: 0.0, options: UIViewAnimationOptions.curveEaseInOut, animations: {
dst.view.transform = CGAffineTransform(translationX: 0, y: 0)
}) { (finished) in
src.present(dst, animated: false, completion: nil)
}
}
}
And this is my storyboard, note that i have one segue going to VC2, and one going back to VC1 (both custom segue using the different classes).
Even if i have a print("swiped") when user swipes on VC2 it dosent get printed in console, hence why i think its something wrong with the swipes...
Conclusion: Swipe does work on VC1 and segue to VC2 works, however swipe on VC2 does not work at all...
