I have a Main screen and when I press a button I will be sent to the second view controller I create a storyboard segue of type: 'Show' but when I press the button the second screen is presented as a modal.
Ps: I'm already embed navigation controller in the first view controller
Ps2: the second view controller is placed in another storyboard file, so the connection of the segue is from the main view controller to a reference storyboard.

I tried to build a simple segue. Therefor I embedded a Navigation Controller and set it as the initial View Controller. I then created the segue (kind: show) to a different ViewController.
Storyboard
Even the storyboard looks right and I can run the app without any Errors or Warnings.
But when I open the app in the simulator and press on the button to switch screens the new view pops up like a modal presentation.
Simulator
None of this is done programmatically. To solve this issue I tried different segue kinds after that I rebuild the Navigation Controller and segue entirely but it changed nothing.
I just created two view controllers, embedded a nav controller and then connected a button in the first view controller to the second. In the simulator, pressing the button showed the second view controller with a nav bar on top. Try deleting the current segue and nav controller, and then embed in the nav controller and create the segue again.

This is my story board:
Whenever I jump to a view controller embedded in navigation controller, the navigation bar is shown but empty, why?
The sequence I created it is:
connect buttons with destination view controllers
embed destination view controllers in navigation view controller
And the segue I use is present modally - cross dissolve.
The First root controllers of a navigation controller won't have any Back button attached to its navigation bar. You should add an additional View Controller next to any root View Controller of Navigation Controller with Push Segue ( or Show Segue for newer IOS ) to navigate between them.
I tested different segue transition methods with test projects, the answer I got is: if you are transitioning by presenting it modally, you don't get the back button, you only get it by push.
I have three view controllers in my storyboard.
In second controller I have navigation controller embeded. Second controller is connected to third with segue.
From first view controller, I call second one by presentViewController. In presented view controller I press a button that trigger a segue. What I expect is to see navigation controller in second and third view controller, but third viewcontroller is also shows from bottom to top with out navigation controller.
How to make nav controller visible in second and third view controller ?
Select the segue
between your secondView and thirdView in your StoryBoard
and look it has this settings:
Take care the identifier is what you want, the key here is the kind type of segue
I have to view controller, One has a button and the other is embed in a navigation controller. I Don't know how to make a proper segue to that second view controller including a back (unwind) segue. That is in swift.
You're going to use a navigation controller. Go and select your view in the storyboard, and select Editor -> Embed In -> Navigation Controller. Do the same for the second view. Now, add a button in the first view that connect to the second view on a click. Make sure when you drag and drop that it's a push segue.
Voila! You should now have your navigation controller working.
I have a storyboard setup as a Tabbed Application with first view controller containing a
UITableView. The Protoype cell has a "push" segue to detail view which is embedded in a navigation controller. So far so good. The detail view pushes when a cell is selected and there is a navigation bar item to get back to the table view.
Now I run into trouble. The detail view has 2 buttons "Map" and "Ticket". If I create a new UIViewController, embed it in a navigation controller, and ctril-drag a 'push' segue from a button to the new view controller as before, the app crashes instantly with a SIGABRT when I click the button. If I don't embed in nav controller and use a 'modal' segue instead it doesn't crash but it seems a natural flow to continue with the 'horizontal slide' animation and the nav bar button back to the detail view.
Once I can stop that crashing I would like to connect the other button to it's own view controller with a UIMapView.
What am I doing wrong?
You don't need to embed a navigation controller in the detail view. You only need one at the top level. Take out the navigation controller in the detail view controller and just do a push from there to the next view.
