PrefersLargeTitle won't work using InterfaceBuilderControllerContainer

[muizidn]

protocol InterfaceBuilderControllerContainer: UIViewController {
    associatedtype XibController: InterfaceBuilderController
}

extension InterfaceBuilderControllerContainer {
    var xibController: XibController {
        children.first(where: { $0 is XibController }) as! XibController
    }
    
    init(withXib: Bool) {
        self.init()
        let vc = XibController.create()
        addChild(vc)
        view.add(vc.view) { v in
            v.flex.grow(1)
        }
        vc.didMove(toParent: self)
    }
}

This protocol will synthesise capability of conforming controller to layout using child interface builder information. But it seems, something strange happens. If we use this protocol initialiser over BaseController convenience one, then prefersLargeTitles won't work.

Investigating....

Actually this also introduces new issue.

The initialiser will invoke loadView -> viewDidLayout -> startBind which causes crash because viewModel is uninitialised yet.
