swift tap gesture handler not invoked - swift

Question

I have the following custom view implementation :
import UIKit
class ProfileTableHeaderView: UITableViewHeaderFooterView {
private var statusText : String = ""
private let fullNameLabel: UILabel = {
let view = UILabel()
view.text = "Hipster Pinguin"
view.font = UIFont.systemFont(ofSize: 18, weight: .bold)
view.textColor = .black
view.translatesAutoresizingMaskIntoConstraints = false
return view
}()
private let avatarImage: UIImageView = {
let view = UIImageView()
view.clipsToBounds = true
view.layer.borderWidth = 3
view.layer.borderColor = UIColor.white.cgColor
view.image = UIImage(named: "avatar")
view.contentMode = .scaleAspectFill
view.layer.cornerRadius = 100/2
view.translatesAutoresizingMaskIntoConstraints = false
// let tapGesture = UITapGestureRecognizer(target : self, action : #selector(avatarImagePressHandler))
// view.isUserInteractionEnabled = true
// view.addGestureRecognizer(tapGesture)
return view
}()
let statusLabel: UILabel = {
let view = UILabel()
view.text = "Waiting for something"
view.font = UIFont.systemFont(ofSize: 14, weight: .regular)
view.textColor = .gray
view.translatesAutoresizingMaskIntoConstraints = false
return view
}()
let statusTextField: UITextField = {
let view = TextFieldWithPadding()
view.placeholder = "add smth to show as status"
view.layer.cornerRadius = 12
view.layer.borderWidth = 1
view.layer.borderColor = UIColor.black.cgColor
view.backgroundColor = .white
view.font = UIFont.systemFont(ofSize: 15, weight: .regular)
view.textColor = .black
view.backgroundColor = .white.withAlphaComponent(0)
view.addTarget(self, action: #selector(statusTextChanged), for : .editingChanged)
view.translatesAutoresizingMaskIntoConstraints = false
return view
}()
let setStatusButton: UIButton = {
let view = UIButton()
view.setTitle("Show status", for: .normal)
view.setTitleColor(.white, for : .normal)
view.backgroundColor = UIColor(named: "myColor")
view.layer.cornerRadius = 14
view.layer.shadowRadius = 4
view.layer.shadowColor = UIColor.black.cgColor
view.layer.shadowOpacity = 0.7
view.layer.shadowOffset = CGSize(width: 4, height: 4)
view.addTarget(self, action: #selector(buttonPressed), for: .touchUpInside)
view.translatesAutoresizingMaskIntoConstraints = false
return view
}()
override init(reuseIdentifier: String?) {
super.init(reuseIdentifier: reuseIdentifier)
setupViews()
}
#objc func avatarImagePressHandler()
{
print("avatar pressed")
}
#objc func buttonPressed()
{
statusLabel.text = statusText
}
#objc func statusTextChanged(_ textField: UITextField)
{
statusText = textField.text ?? ""
}
required init?(coder: NSCoder) {
fatalError("should not be called")
}
private func setupViews()
{
contentView.addSubview(avatarImage)
contentView.addSubview(fullNameLabel)
contentView.addSubview(statusLabel)
contentView.addSubview(statusTextField)
contentView.addSubview(setStatusButton)
let tapGesture = UITapGestureRecognizer(target : self, action : #selector(avatarImagePressHandler))
avatarImage.isUserInteractionEnabled = true
avatarImage.addGestureRecognizer(tapGesture)
let constraints = [
avatarImage.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 16),
avatarImage.leadingAnchor.constraint(equalTo: contentView.leadingAnchor, constant: 16),
avatarImage.widthAnchor.constraint(equalToConstant: 100),
avatarImage.heightAnchor.constraint(equalToConstant: 100),
fullNameLabel.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 27),
fullNameLabel.leadingAnchor.constraint(equalTo: avatarImage.trailingAnchor, constant: 16),
fullNameLabel.trailingAnchor.constraint(equalTo: contentView.trailingAnchor, constant: -16),
statusLabel.topAnchor.constraint(equalTo: fullNameLabel.bottomAnchor, constant: 10),
statusLabel.leadingAnchor.constraint(equalTo: fullNameLabel.leadingAnchor),
statusLabel.trailingAnchor.constraint(equalTo: fullNameLabel.trailingAnchor),
statusTextField.topAnchor.constraint(equalTo: statusLabel.bottomAnchor, constant: 10),
statusTextField.heightAnchor.constraint(equalToConstant: 40),
statusTextField.leadingAnchor.constraint(equalTo: statusLabel.leadingAnchor),
statusTextField.trailingAnchor.constraint(equalTo: statusLabel.trailingAnchor),
setStatusButton.topAnchor.constraint(equalTo: avatarImage.bottomAnchor, constant: 16),
setStatusButton.leadingAnchor.constraint(equalTo: avatarImage.leadingAnchor),
setStatusButton.trailingAnchor.constraint(equalTo: contentView.trailingAnchor, constant: -16),
setStatusButton.heightAnchor.constraint(equalToConstant: 50)
]
NSLayoutConstraint.activate(constraints)
}
}
If I try to setup a tap gesture recognizer inside lambda I see no print inside the console, but if I configure it inside setupViews everything is fine. Why does it work this way? What am I missing?
