Load controllers from storyboard about parchment HOT 4 CLOSED

Yes, you need to load each view controller using instantiateViewController: on the storyboard and then manually setup a PagingViewController. Here's an example:

override func viewDidLoad() {
    super.viewDidLoad()
    
    // Load each of the view controllers you want to embed
    // from the storyboard.
    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let firstViewController = storyboard.instantiateViewController(withIdentifier: "FirstViewController")
    let secondViewController = storyboard.instantiateViewController(withIdentifier: "SecondViewController")
    
    // Initialize a FixedPagingViewController and pass
    // in the view controllers.
    let pagingViewController = FixedPagingViewController(viewControllers: [
      firstViewController,
      secondViewController
    ])
    
    // Make sure you add the PagingViewController as a child view
    // controller and contrain it to the edges of the view.
    addChildViewController(pagingViewController)
    view.addSubview(pagingViewController.view)
    view.constrainToEdges(pagingViewController.view)
    pagingViewController.didMove(toParentViewController: self)

  }

I will look into other ways of setting up a PagingViewController directly in the storyboard in the future. I've added a StoryboardExample to the project that you can check out if you want to see how the setup looks like in the storyboard.

@rechsteiner thanks for the quick response and the example.

I tried the above code (StoryboardExample) it works fine as is. So, I tried extending it a bit by adding a class (swift file) to one of the controllers (FirstViewController) as below:

>>>>>

import UIKit

class FirstViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()

    print("In first VC")
    // Do any additional setup after loading the view.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

}
<<<<<

I expected the message "In first VC" (from viewDidLoad()) to get printed to the console when the app is fired but, that does not seem to happen. Am I doing something wrong? or is this what you were referring to as future work?

Yeah, you need to set class type for that view controller. You can just select the view controller in the storyboard and then set the Custom Class property to be FirstViewController like this:

I did set the class. The issue seems to be with the compiler. It worked perfectly after I ran it after a clean build. Thanks again for the quick response and the example.
