IOS 16 UITableViewCell accessibility API not working, breaking XCTest - ios

Question

Since the upgrade to IOS 16 the accessibility api for cells has stopped working.
Using this API's is not working anymore:
In a CellConfiguration
public struct CellConfiguration: UIContentConfiguration {
public func makeContentView() -> UIView & UIContentView {
CellContent(configuration: self)
}
public func updated(for state: UIConfigurationState) -> CellConfiguration {
self
}
}
private class CellContent: UIView, UIContentView {
init(configuration: UIContentConfiguration) {
self.configuration = configuration
super.init(frame: .zero)
isAccessibilityElement = true
accessibilityLabel = "I'm a label"
accessibilityValue = "I'm a value"
accessibilityTraits = [.header] // or other traits as well
accessibilityIdentifier = "cellID"
}
}
In a UITableViewController
private func createCell(in tableView: UITableView) -> UITableViewCell? {
guard let cell = tableView.dequeueReusableCell(withIdentifier: "cellIdentifier")
else { return nil }
cell.contentConfiguration = CellConfiguration()
cell.selectionStyle = .none
return cell
}
The cell is not accessible in the simulator and on the phone. I can't find it. This has worked prior to IOS16. Thus breaking any existing XCTest's and any progress implementing app that has accessibility.

This is the right way, declare objects and set attributed an constraints:
class YourViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
let cellId = "cellId"
let tableView = UITableView()
override func viewDidLoad() {
super.viewDidLoad()
setupTableView()
}
fileprivate func setupTableView() {
view.backgroundColor = .white
view.addSubview(tableView)
tableView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor).isActive = true
tableView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
tableView.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true
tableView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
tableView.delegate = self
tableView.dataSource = self
tableView.translatesAutoresizingMaskIntoConstraints = false
tableView.register(MyCell.self, forCellReuseIdentifier: cellId) // register your cell
tableView.backgroundColor = #colorLiteral(red: 0.94826442, green: 0.9495814443, blue: 0.96922189, alpha: 1)
tableView.separatorColor = UIColor(white: 1, alpha: 0.4)
//tableView.tableFooterView = UIView()
if #available(iOS 15.0, *) {
tableView.sectionHeaderTopPadding = 0 // remove blank space on top o tableView
} else {
UITableView.appearance().sectionHeaderTopPadding = CGFloat(0) // remove blank space on top o tableView in old OS
}
now set delegate and datasource:
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let v = UIView()
let label = UILabel()
switch section {
case 0:
v.backgroundColor = #colorLiteral(red: 0.94826442, green: 0.9495814443, blue: 0.96922189, alpha: 1)
label.text = "Section 1"
default:
label.text = "Section 2"
v.backgroundColor = #colorLiteral(red: 0.94826442, green: 0.9495814443, blue: 0.96922189, alpha: 1)
}
label.translatesAutoresizingMaskIntoConstraints = false
label.textColor = .systemBlue
v.addSubview(label)
label.topAnchor.constraint(equalTo: v.topAnchor).isActive = true
label.leadingAnchor.constraint(equalTo: v.leadingAnchor, constant: 20).isActive = true
label.trailingAnchor.constraint(equalTo: v.trailingAnchor).isActive = true
label.bottomAnchor.constraint(equalTo: v.bottomAnchor).isActive = true
return v
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 30
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableView.automaticDimension
}
func numberOfSections(in tableView: UITableView) -> Int {
return 2
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
switch section {
case 1:
return 1
default:
return 1
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: cellId, for: indexPath) as! MyCell
let section = indexPath.section
switch section {
case 0:
cell.myLabel.text = "Title: I'm a label"
cell.subtitle.text = "Subtitle: I'm a value"
default:
cell.myLabel.text = "Title: I'm a label2"
cell.subtitle.text = "Subtitle: I'm a value2"
}
return cell
}
Your cell looks like:
class MyCell: UITableViewCell {
let myLabel: UILabel = {
let label = UILabel()
label.textColor = .black
label.translatesAutoresizingMaskIntoConstraints = false
return label
}()
let subtitle: UILabel = {
let label = UILabel()
label.textColor = .gray
label.translatesAutoresizingMaskIntoConstraints = false
return label
}()
override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
contentView.backgroundColor = .white
let stackView = UIStackView(arrangedSubviews: [myLabel, subtitle])
stackView.distribution = .fillEqually
stackView.axis = .vertical
stackView.spacing = 2
stackView.translatesAutoresizingMaskIntoConstraints = false
contentView.addSubview(stackView)
stackView.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 20).isActive = true
stackView.leadingAnchor.constraint(equalTo: contentView.leadingAnchor, constant: 20).isActive = true
stackView.trailingAnchor.constraint(equalTo: contentView.trailingAnchor).isActive = true
stackView.bottomAnchor.constraint(equalTo: contentView.bottomAnchor, constant: -20).isActive = true
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
this is the result:
