Loading ViewController from xib file

Question

I had a MyViewController.swift and a MyViewController.xib presenting the layout of MyViewController.

I tried different methods to load this

Answer 1

I removed File owner’s class name and set that to the class name of first view. And then I had to set outlets to the components which I’m going to use.

Then I loaded that view class like

let myViewController = Bundle.main.loadNibNamed("MyViewController", owner: self, options: nil)?.first as! MyViewController
view.addSubview(myViewController)

Answer 2

Updated for Swift 5

        let myVC = Bundle.main.loadNibNamed("MyViewController", owner: self, options: nil)![0] as? MyViewController

Answer 3

extension UIViewController {
    static func loadFromNib() -> Self {
        func instantiateFromNib<T: UIViewController>() -> T {
            return T.init(nibName: String(describing: T.self), bundle: nil)
        }

        return instantiateFromNib()
    }
}

Use it as the following:-

let testVC = TestVC.loadFromNib()

Answer 4

I had the same problem. The automatically generated xib had a UIView in it. You have to delete the view, add new view controller to the xib, set the view controller class to the one you want and then connect the outlets. After all of this you can use the codes provided above to get an instance of this view controller, like this:

if let menuVC = Bundle.main.loadNibNamed("MenuViewController", owner: nil, options: nil)?.first as? MenuViewController {
            menuVC.profileType = profileType
            vc.present(menuVC, animated: true, completion: nil)
        }
