UICollectionView with orthogonal (horizontal) section not calling touchesShouldCancel(in:)
I have a UICollectionView with horizontally scrolling sections. In the cell I have a UIButton. I need to cancel the touches when the user swipes horizontally but it does not work. touchesShouldCancel(in:) is only called when swiping vertically over the UIButton, not horizontally. Is there a way to make it work? Sample code below import UIKit class ConferenceVideoSessionsViewController: UIViewController { let videosController = ConferenceVideoController() var collectionView: UICollectionView! = nil var dataSource: UICollectionViewDiffableDataSource <ConferenceVideoController.VideoCollection, ConferenceVideoController.Video>! = nil var currentSnapshot: NSDiffableDataSourceSnapshot <ConferenceVideoController.VideoCollection, ConferenceVideoController.Video>! = nil static let titleElementKind = "title-element-kind" override func viewDidLoad() { super.viewDidLoad() navigationItem.title = "Conference Videos" configureHierarchy() configureDataSource() } } extension ConferenceVideoSessionsViewController { func createLayout() -> UICollectionViewLayout { let sectionProvider = { (sectionIndex: Int, layoutEnvironment: NSCollectionLayoutEnvironment) -> NSCollectionLayoutSection? in let itemSize = NSCollectionLayoutSize(widthDimension: .fractionalWidth(1.0), heightDimension: .fractionalHeight(1.0)) let item = NSCollectionLayoutItem(layoutSize: itemSize) // if we have the space, adapt and go 2-up + peeking 3rd item let groupFractionalWidth = CGFloat(layoutEnvironment.container.effectiveContentSize.width > 500 ? 0.425 : 0.85) let groupSize = NSCollectionLayoutSize(widthDimension: .fractionalWidth(groupFractionalWidth), heightDimension: .absolute(200)) let group = NSCollectionLayoutGroup.horizontal(layoutSize: groupSize, subitems: [item]) let section = NSCollectionLayoutSection(group: group) section.orthogonalScrollingBehavior = .continuous section.interGroupSpacing = 20 section.contentInsets = NSDirectionalEdgeInsets(top: 0, leading: 20, bottom: 0, trailing: 20) return section } let config = UICollectionViewCompositionalLayoutConfiguration() config.interSectionSpacing = 20 let layout = UICollectionViewCompositionalLayout( sectionProvider: sectionProvider, configuration: config) return layout } } extension ConferenceVideoSessionsViewController { func configureHierarchy() { collectionView = MyUICollectionView(frame: .zero, collectionViewLayout: createLayout()) collectionView.translatesAutoresizingMaskIntoConstraints = false collectionView.backgroundColor = .systemBackground view.addSubview(collectionView) NSLayoutConstraint.activate([ collectionView.leadingAnchor.constraint(equalTo: view.leadingAnchor), collectionView.trailingAnchor.constraint(equalTo: view.trailingAnchor), collectionView.topAnchor.constraint(equalTo: view.topAnchor), collectionView.bottomAnchor.constraint(equalTo: view.bottomAnchor) ]) collectionView.canCancelContentTouches = true } func configureDataSource() { let cellRegistration = UICollectionView.CellRegistration <ConferenceVideoCell, ConferenceVideoController.Video> { (cell, indexPath, video) in // Populate the cell with our item description. cell.buttonView.setTitle("Push, hold and swipe", for: .normal) cell.titleLabel.text = video.title } dataSource = UICollectionViewDiffableDataSource <ConferenceVideoController.VideoCollection, ConferenceVideoController.Video>(collectionView: collectionView) { (collectionView: UICollectionView, indexPath: IndexPath, video: ConferenceVideoController.Video) -> UICollectionViewCell? in // Return the cell. return collectionView.dequeueConfiguredReusableCell(using: cellRegistration, for: indexPath, item: video) } currentSnapshot = NSDiffableDataSourceSnapshot <ConferenceVideoController.VideoCollection, ConferenceVideoController.Video>() videosController.collections.forEach { let collection = $0 currentSnapshot.appendSections([collection]) currentSnapshot.appendItems(collection.videos) } dataSource.apply(currentSnapshot, animatingDifferences: false) } } class MyUICollectionView: UICollectionView { override func touchesShouldCancel(in view: UIView) -> Bool { print("AH: touchesShouldCancel view \(view.description)") if view is MyUIButton { return true } return false } } final class MyUIButton: UIButton { } class ConferenceVideoCell: UICollectionViewCell { static let reuseIdentifier = "video-cell-reuse-identifier" let buttonView = MyUIButton() let titleLabel = UILabel() override init(frame: CGRect) { super.init(frame: frame) configure() } required init?(coder: NSCoder) { fatalError() } } extension ConferenceVideoCell { func configure() { buttonView.translatesAutoresizingMaskIntoConstraints = false titleLabel.translatesAutoresizingMaskIntoConstraints = false contentView.addSubview(buttonView) contentView.addSubview(titleLabel) titleLabel.font = UIFont.preferredFont(forTextStyle: .caption1) titleLabel.adjustsFontForContentSizeCategory = true buttonView.layer.borderColor = UIColor.black.cgColor buttonView.layer.borderWidth = 1 buttonView.layer.cornerRadius = 4 buttonView.backgroundColor = UIColor.systemPink let spacing = CGFloat(10) NSLayoutConstraint.activate([ buttonView.leadingAnchor.constraint(equalTo: contentView.leadingAnchor), buttonView.trailingAnchor.constraint(equalTo: contentView.trailingAnchor), buttonView.topAnchor.constraint(equalTo: contentView.topAnchor), titleLabel.topAnchor.constraint(equalTo: buttonView.bottomAnchor, constant: spacing), titleLabel.leadingAnchor.constraint(equalTo: contentView.leadingAnchor), titleLabel.trailingAnchor.constraint(equalTo: contentView.trailingAnchor), titleLabel.bottomAnchor.constraint(equalTo: contentView.bottomAnchor) ]) } }

CoreMediaErrorDomain error -42709
We are getting reports from customers that they are not able to play videos in our app after updating their phones to iOS18.3.1. (Further checking indicates that it happens on all iOS18 versions. It suddenly started occurring from February 18th, 2025) When checking logs we see that playback is failing due to CoreMediaErrorDomain error -42709. This is an undocumented error code and hence we do not know the cause of the playback issue. Does anyone know what this error code means and how the app should handle it? Reported as FB16638501.

Test In-App purchase on AdHoc build
Hi,In the documentation it says you must use a sandbox account when testing In-App purchase using the Sandbox.But I just noticed that (currently on 10.3 release) the StoreKit popup is saying "Sandbox" even when using a normal account but the app is an AdHoc build.Is this expected that a normal account also uses the "Sandbox" when running a AdHoc distribution build?Thanks in advance,Anders

AVPlayer and Cookie Expiration
Hi,I have some questions about how AVPlayer handles updates of a cookie's expiration time.We do something like this:1) Send a GET request to server which sets authentication cookie. This cookie has a short expiration time, CookieExpiryTime.2) Start AVPlayer. The authentication cookie is included in the AES key request.3) Every n minutes (where n is CookieExpiryTime/2), send new GET request to authentication server to get updated cookie expiration time. By logging all cookies in NSHTTPCookieStorage.sharedHTTPCookieStorage() we can see that the expiration time of the cookie is updated.The problem:When a key is requested after the expiration time of the first cookie from 1), the cookie is no longer included in the AES key request.But shouldn't the updated cookie (with extended expiration time) be considered?Question 1) Does AVPlayer filter out expired cookies when doing the AES key requests?Question 2) Does AVPlayer check NSHTTPCookieStorage.sharedHTTPCookieStorage() for updated cookies after init?Thanks,Anders

ASWebAuthenticationSession failing to access cookies only in Simulator
We are using an ASWebAuthenticationSession to authenticate using an already logged in session in Safari. This works fine on real hardware. In Simulator from iOS13.5, the callback URL is always missing the session ID which indicates that ASWebAuthenticationSession couldn't access the cookies. We are not using session cookies. As documented here: https://developer.apple.com/documentation/authenticationservices/authenticating_a_user_through_a_web_service Does anyone have any suggestion how to debug this and figure out if the problem is on our side or iOS side?
