类“ProfileController”没有初始值设定项

没有初始值的存储属性“profileImageView”阻止合成初始值设定项

代码是这样的:(在底部使用POP)

class ProfileController: UIViewController {

 override func viewDidLoad() {
    super.viewDidLoad()
    self.view.backgroundColor = UIColor.white
    self.navigationItem.title = "Profil"
    self.navigationItem.largeTitleDisplayMode = .never
    fillData()
    setupView()
    confBounds()
 }

 func fillData() {
    profileImageView.image = UIImage(named: "test")
 }

 func setupView() {
    view.addSubview(profileImageView)
 }

 func confBounds() {
    profileImageView.centerXAnchor.constraint(equalTo: self.view.centerXAnchor).isActive = true
    profileImageView.anchor(top: self.view.topAnchor, left: nil, bottom: nil, right: nil, paddingTop: 60, paddingLeft: 0, paddingBottom: 0, paddingRight: 0, width: 140, height: 140)
 }

 let profileImageView: UIImageView, CustomAnchor = { () -> UIImageView in
    let pView = UIImageView()
    pView.contentMode = .scaleAspectFill
    pView.clipsToBounds = true
    pView.image = UIImage(named: "test")
    return pView
 }()
}
