Swift load UIViewController from xib IBOutlets nil

Question

I'm pulling out what little hair I have left!

I have a UIViewController with a matching .xib file. In the .xib, I have an IBOutlet that I made in interface builder called "titleText"

In a section of my code, I have the following lines:

let fooVC = FooViewController(nibName: "FooViewController", bundle: Bundle.main)
fooVC.titleText = "TEST"

The viewController "seems" to load fine, I get an object of the correct type, but the IBOutlets are not initialized.

Is there an additional step that I need to do to initialize any IBOutlets that I may have?

This has got to be something really simple, right?!

Outlets are nil until the view loads. So just make another variable and store title string like below

class FooViewController: UIViewController {
    @IBOutlet titleText:UILable!
    var titleString:String?

    override func viewDidLoad() {
       super.viewDidLoad()
       titleText.text = titleString
    }
}

Use:

let fooVC = FooViewController()
fooVC.titleString = "TEST"

No , loadViewIfNeeded will make it load – Shehata Gamal Nov 17 '18 at 04:28
The fix that actually worked for me was `_ = self.view` in the `viewDidLoad()` method – Perlguy Nov 19 '18 at 22:38
