ios – Customized nameless closure navigation again button inside UiView()

I’ve a query, how is it potential to implement the creation of a customized again navigation button inside an UIView(). I’ve a important controller which accommodates a collectionView, clicking on any cell goes to a second controller which accommodates a tableView. I created a separate customized view contained in the tableView headers the place I added labels, photos, buttons. I would like when clicking a backButton inside a customized view, it should go to the primary controller. How could be carried out? I making app solely programmatically – (No Storyboard)

CustomView.swift

lazy var backButton: UIButton = {
    let button = UIButton(sort: .system)
    let picture = UIImage(systemName: "chevron.left")
    button.setImage(picture, for: UIControl.State())
    button.tintColor = .white
    button.isHidden = true
    button.addTarget(self, motion: #selector(goToBack), for: .touchUpInside)
    button.translatesAutoresizingMaskIntoConstraints = false
    return button
}()

@objc func goToBack() {
    
}
