How to show IBInspectable of sub component in custom view?

Question

I have a custom view that have a label and text field and was connected to my nib file.

I want to edit them using attribute inspector, but the only component that I see on the attribute inspector was the parent UIView

How can I show the whole inspectable of the UILabel and UITextField in the attribute inspector?

@IBDesignable
class CustomView: UIView {
    @IBOutlet weak var label: UILabel!
    @IBOutlet weak var textField: ChimeTextField!
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        self.configureView()
    }
    
    required init?(coder: NSCoder) {
        super.init(coder: coder)
        self.configureView()
    }
    
    private func configureView() {
        guard let view = self.loadViewFromNib(nibName: "CustomView") else { return }
        view.frame = self.bounds
        self.addSubview(view)
    }

}
