UIControl not recognizing tap inside table view cell, stopped working from iOS 14 - ios

Question

I have an application I started, before iOS 14 came out. I stopped with Swift for few months, and now, the emulator is running iOS 14, since then, I have a problem that a UIControl I have inside a tableView cell does not register taps.
This is my TableView (plain, nothing custom or anything):
private let tableView: UITableView = {
let table = UITableView(frame: .zero, style: .plain)
table.translatesAutoresizingMaskIntoConstraints = false
table.backgroundColor = .white
table.separatorInset.right = table.separatorInset.left
return table
}()
This is how I try to set the tap gesture:
extension TodoListVC: UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: todoCellIdentifier, for: indexPath) as! TodoCell
let todo = todoListViewModel.todos[indexPath.row]
cell.model = todo
cell.selectionStyle = .none
let checkBox = cell.checkbox
checkBox.index = indexPath.row
checkBox.addTarget(self, action: #selector(onCheckBoxValueChange(_:)), for: .valueChanged) // touchUpInside also does not work.
return cell
}
#objc func onCheckBoxValueChange(_ sender: UICheckBox) {
var todo = todoListViewModel.todos[sender.index]
todo.isDone = sender.isChecked
tableView?.reloadRows(at: [IndexPath(row: sender.index, section: 0)], with: .none)
todoListView.reloadProgress()
}
}
The checkbox is a custom UIControl I copied from a tutorial, it worked great before iOS 14, and I can't figure out what's the problem with it now. The file is quite large to add here, but if this is necessary I can provide the code.

Go to your TodoCell and add this in your initializer:
override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
contentView.isUserInteractionEnabled = true
}
It will start working again. If you have not created the cells programatically then you can do this:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: todoCellIdentifier, for: indexPath) as! TodoCell
let todo = todoListViewModel.todos[indexPath.row]
cell.model = todo
cell.selectionStyle = .none
cell.contentView.isUserInteractionEnabled = true
let checkBox = cell.checkbox
checkBox.index = indexPath.row
checkBox.addTarget(self, action: #selector(onCheckBoxValueChange(_:)), for: .valueChanged) // touchUpInside also does not work.
return cell
}
To debug, you can print the value of contentView.isUserInteractionEnabled and it will give you the boolean and using that you can see if it is the issue or not. Most probably it will return false and the above solution works well for iOS 14 and Xcode 12.
