As the name suggests we are overriding the default with our code, copy and paste or enter the code below in ‘ViewController.swift' and see the screenshot for reference. Now the next step (yes I know it seems like a lot of steps!) is to create code that assigns (injects) the entry field text to our variables in the second view, we do this by overriding something called prepareForSegue in the first viewController. Then press control and drag the button to the target screen. The code for the view controller should now look something like this. The easiest way to switch between screens in iOS is. Any connections between the view controller and the nib file objects are created automatically, and in iOS, the UIViewController object also receives additional notifications when the views are.

I also added an for the button but it is not needed for the segue to take place, I just added it in case I want to do some extra things when it is clicked. If you specify a nib file when creating the view controller, that nib file is loaded automatically when you try to access the view controller’s view. Right-click and drag from the first text entry field to the controller code and create an named ‘fieldA', then do the same with the second text entry field and name it ‘fieldB'. Make sure you are using the first view controller and open the assistant editor (the second icon on the right-hand side of the Xcode icon bar), you should see the viewController.swift file appear. Storyboards allow you to prototype and design multiple view controller views within one file, and also let you create transitions between view controllers. See the video below if you need extra help to make sense of it.

This assumes you want to present something on the parent view controller. When you are configuring the collection view cell, you can set the delegate of the cell at this point. From the popup menu select Action Segue > show, this sets up the segue to take place when the button is pressed. Collection view data sources are commonly the view controller that hosts the collection view. The sender parameter refer to the object which initiated this segue, we put 'self' to indicate that this segue is initiated by the InputViewController.To pass the data and switch views we use a segue, (I have added an extra step here in case I want to do anything extra when the button is clicked), right-click the button and drag to the second view controller and release. This method tells the InputViewController to perform a segue to DisplayViewController.

When the Next button is tapped, we will tell the InputViewController to perform the segue. Instead, UIKit determines the target of an unwind segue programmatically at runtime. Unlike the segues that you use to present view controllers, an unwind segue promises the dismissal of the current view controller without promising a specific target for the resulting transition. Usually my naming convention will be "sourceVCtoDestinationVC". To handle the dismissal of a view controller, create an unwind segue. Then select the segue between view controller, and set an identifier for it, we will use this identifier on the next step.

After releasing the mouse click, select ' Show' inside Manual Segue.
