NavigationBar back button strange behavior and not working

Question

I have encountered a strange behavior on the back button of a navigation bar. I will try my best to describe with with screenshots(through links, as I cant not upload yet)

Here is the first screen, or the parent view with the navigation bar hidden: Screen 1

Here is the code for first screen:

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationController?.navigationBarHidden = false
    // Do any additional setup after loading the view.
}
override func viewWillAppear(animated: Bool) {
    self.navigationController?.navigationBarHidden = false
}

This is my code for pushing the view controller:

var second = self.storyboard?.instantiateViewControllerWithIdentifier("As_ThirdViewControllerID") as! As_ThirdViewController!

self.navigationController?.pushViewController(second, animated: true)

When you click the last tab bar button, it will bring you to a second screen: Screen 2

Same code as first screen, only, the navigation bar is NOT hidden

Now, in that second screen, you can see a BUTTON...when you click the button you will be brought to the third and last screen: Screen 3

Same code as first screen, only, the navigation bar is NOT hidden

THE STRANGE BEHAVIOR: When I swipe going back(third screen -> second -> parent) -- ITS WORKING.. When I press back button from the THIRD and last screen --> it looks like this: Screen 4 -- NOT WORKING, not going back to the previous screen...the word "back" suddenly goes away from the arrow

I don't have a lot of codes in my classes as of now as I am just starting and formulating the design, so I could not figure out what's wrong with my program..

Make the links to be accessed by everyone, without having to request access. — E-Riddie, Aug 25 '15 at 11:02
I made the tag objective c to attract attention from people who know how objective C, maybe they already encountered this in the past.. I hope you can help me. — Raymond Led Carasco, Aug 25 '15 at 11:08
Hello, I do not have any code to pop back, the back button goes with the navigation bar, so it makes me confused as to why it would behave that way. — Raymond Led Carasco, Aug 25 '15 at 11:45

This usually happens when you have navigationController stack and navigationBar stack mismatch.

Try adding custom button and selector then pop using

self.navigationController.popViewController(viewController);

The mismatch happens because you don't have navigation bar button on one VC and have on others. – Rohit Kumar Aug 26 '15 at 05:54
Why did you post the question twice? http://stackoverflow.com/questions/32218716/navigation-button-strange-behavior-not-working-with-video (Another one) – Rohit Kumar Aug 26 '15 at 06:13
Post your complete code or host it somewhere. I have tried your scenario and unable to reproduce the problem. It's working fine for me. – Rohit Kumar Aug 26 '15 at 06:21
You should have edited your original question. You may receive lots of downvotes by doing so. – Rohit Kumar Aug 26 '15 at 06:31
Noted, I will edit it, but, what do you think is the problem with my navigation controller/bar? Have you seen the other post? – Raymond Led Carasco Aug 26 '15 at 07:01
I have tried pushing popping with gestures also but unable to reproduce the problem. – Rohit Kumar Aug 26 '15 at 07:03
Have you watched my video? At the second screen, try swiping back..but dont continue it and just stay at the second view controller half way through swiping – Raymond Led Carasco Aug 26 '15 at 07:18

I could not edit my own post, the site says it has unformatted codes, when all I have added was a sentence below the post that had codes in it before I even edited it. I don't what happened.

But here's what I did:

It appears this is a bug in iOS, I saw a similar post and no one has solved the problem itself:

Navigation stack becomes unusable after canceling iOS 7 back swipe gesture

I just followed the suggestion and disabled the interactivePopGestureRecognizer
