I am developing in Xcode 14 with Storyboards. I have set up several ViewControllers and when I add segues, the views become Modal and have a gap at the top. This is not what I want. I've tried each of the segue types and none of them allow the 2nd VC to present full-screen. Before and After screenshots below. How does one now use segues to push VCs without them looking like modals?
Xcode changed the default style years ago.
To allow the 2nd VC to present full-screen:
In Xcode IDE, select segue, change its Kind to Present Modally and the presentation style to Full Screen.
In Swift Code, you can assign viewcontroller's modalPresentationStyle to .fullScreen
I am new to iOS development and have not tried this programmatically yet. I would prefer to get this working in a storyboard.
I'm following this somewhat outdated tutorial from XCode 4.5 in XCode 6.1 to create a series of views connected by one navigation controller.

Once I create the second view controller, I am unable to double click the navigation bar to change the name and I am unable to add a bar button to it.
I have a Segue going from bar button "Item" from view 1 to 2. Notice in the "View Controller Scene" there is no navigation item. If I add any elements to the view controller they fall under "View" and not under "View Controller", unlike view controller 1 where it falls under "one".
Is this a limitation on XCode? Am I using the wrong Segue (Show)? Is there a hidden setting or customization I'm missing?
I actually have this working for 2 view controllers and failing the 3rd in a separate project but I don't know what I did to do that so I'm pretty sure it's possible I just cannot reproduce..
EDIT: Workaround Instead of the new adaptive SHOW segue, use the deprecated PUSH segue, add the bar button items, then change back to the adaptive SHOW segue.
Try adding a Navigation Item to the controller and it should work properly
So I was doing a test for another swift project and I wanted to connect a TableViewController that had a NavigationController embedded in to a regular ViewController using a segue between a bar button item and the second ViewController. When I control-drag the button to the ViewController, I only get the following options:
From what I understand, I should see a long list of items including show and show detail. Even if I connect them with push or any other segue, I can't select show or show detail as the type of segue if I select the segue. What am I doing wrong? I have not made modifications to ViewController.swift. Thanks!
The new adaptive segue choices, "show", "show detail", and "present modally", and "popover presentation" are only available if you're using size classes. This makes sense because there's no need for the segue to be adaptive if you're not using size classes.
I have two view controllers in my iPhone application (built with swift) built with Xcode 6.1 and uses storyboards.
The first view controller is embedded in a navigation controller in the storyboard and the segue for the second view controller is a 'Show' segue.
When the application is run, it properly shows the transition as a push in iOS 8.x, but in iOS 7.x it appears as a modal without the navigation bar.
My application requirement is to show the transition as a push regardless of whether it's iOS 7 or iOS 8. Any ideas to get this working as push in both versions of the iOS?
I saw a related post where this issue is mentioned, but could not find a solution to the problem: Adaptive segue in storyboard Xcode 6. Is push deprecated?
Any help is appreciated...
Thanks
This solution is different from the others in the following ways:
It includes a method to examine and verify the issue
The cause of the issue is traced to the source (a change in the segue type)
The solution is very simple (delete and recreate a new segue)
Please note the requirements in the text
I just gave a very detailed SO answer that fully explains what is happening and why, but the simple solution is you can delete the Segue that is not pushing and then recreate it on the storyboard. The reason is that there is likely a broken bit of xml in the segue (see extended answer for example/instructions how to confirm this issue).
After you confirm that you have at least one UINavigationController within the view hierarchy, be sure that the segue is NOT a manual segue and does NOT have an action associated with it (by viewing the segue in the storyboard as Source Code). Delete the existing segue and then Ctrl-drag from a UIView/UIControl to the target view controller and if custom action is needed intercept the call to destination controller in prepareForSegue.
Also to confirm that this solution works for you please do the
following:
Verify that your initial view controller (with the arrow on it) is a
UINavigationController and that it has a normal content view
controller as it's root view controller. (or that you embed your
initial view controller inside of a UINavigationController)
Read my extended comments on an earlier response to a very similar question (linked above).
It's possible that you have assigned the Initial View Controller to your UIViewController instead of the UINavigationController. Also, select your UIViewController and check that the "Is Initial View Controller" option is unchecked.
Here is the workaround for that. It looks like a bug in Xcode for iOS 7. You need to create a dummy UINavigationController and link all your free UIViewControllers to this navigation controller. Worked for me.
For me, my storyboard lacked a navigation controller. I am creating the navigation controller programmatically, which works fine in iOS8, but not iOS7.
SOLUTION
In your storyboard, select the main view controller and in the Xcode menu, choose Editor > Embed In > Navigation Controller.
Select the new navigation controller, and in the attributes inspector on the right, under View Controller, make sure Is Initial View Controller is checked.
Run the app. Should be fixed now.
I believe this is a bug in Xcode 7.2. In order to workaround, you can create a "Push (deprecated)" segue and then in the Storyboard editor, select the segue and change it to Show(e.g. Push)
I have had this exact issue with "Show (eg. Push)" for ages and I have just figured it out whilst trying to push a view controller onto a navigation controller that is in a Popover. It seems that the context of the called View Controller is the problem. So this is how I resolved it:
On the View Controller performing the Segue, check the "Defines Context" property in the Storyboard.
In the called View Controller, set the Presentation property to "Current Context".
I ran into this problem and the only solution I found that works for me is to use the deprecated 'Push' segue.
I am using XCode 9 with Swift 4. Note this version came out yesterday (September 20th).
For me this was just a caching bug. I had to choose "Present Modally", run the app and then choose "Show (e.g. Push)". Now everything works fine.
Basically the answer of Jomafer is partly correct. The controller which you are pushing needs to be preceded by a UINavigationController. You dont really need to push the UINavigationController at all. As long the storyboard knows its within a UINavigationController, all is well.
When a "Show" segue comes up as a modal segue in testing it is usually one of two problems:
The first view controller is not inside a navigation controller.
The storyboard XML is corrupted.
The solution to #2 is usually to remove and replace the segue, and it should correct itself. Sometimes just switching to some other presentation style, running, and switching back to "Show" fixes it.
This can also happen to "Show Detail" segues, and it can be more insidious.
Example:
I have a series of view controllers arranged in a UISplitViewController. They have segues Show->Show->Show->Show Detail. The last segue kept coming up modal. I tried everything to fix that last segue. The problem was that the upstream Show segue had been corrupted into a Show Detail segue (even though the storyboard still said it was a Show segue). I had been testing on iPhone, and I did not discover the real problem until I ran it on the iPad simulator. The segues were now Show->Show->Show Detail->Show Detail. On the iPhone the third segue looked just like a Show because it collapsed onto the navigation controller. However, it is still the detail view controller, and you cannot have a Show Detail from a detail view controller, so the OS does what it can to get your view controller on screen and displays it modally.
Lesson 1: Always test your UISplitViewController on iPad to make sure the segues are doing what you think.
Lesson 2: If your segue is coming up modal unexpectedly, check the upstream segues for corruption as well as the segue in question.
Problem in my case was that I created Show (e.g. Push) segue before putting ViewController as rootViewController of UINavigationController. In other words I didn't have UINavigationController.
Then I deleted seque, added UINavigationController and added seque again and it worked. Tested on Xcode 9.0.1 / iOS 11.0.3.
I know how to do it but i need to know the details, internals. How is it different from modal segue?
replace segue from code
The differences is push segue needs a UINavigationController in order to perform.
A modal segue is not in a navigation stack they can only dismiss themseleves you do not pop view back to the previous controller like you do with a push segue.
A replace segue is only relevant on iPad or iPhone 6+. You can use replace segue to replace the contents of the master or detail pane of a UISplitViewController.
