Build with dsym file works for me. Same issue reproduced in Xcode 15.3

Any feedback from Apple?

Hi @eskimo , thanks for replying and yes, it's really a challenge for us. ============================================ We have had a short touch with this user. He/she is facing a problem where he/she can't receive a specific kind of message for many days. However, he/she has said that the problem has been resolved after uninstalling and reinstalling our app. This means that this issue is highly relevant to our app's data environment. ============================================ My colleague from the server side has informed me that the user's websocket behavior is weird. It connects to our server, sends a normal message(deciding whether the client needs APNs or not), and immediately disconnects. A typical log(from another user also encountering bad address error) looks like this below: [2023-05-26 20:53:42:872][Call webSocketTaskWithRequest:] Create Task: LocalWebSocketTask <XYZ>.<1> withRequest: <NSMutableURLRequest: 0x2807d0480> { URL: A_WS_URL} [2023-05-26 20:53:42:872][Call receiveMessageWithCompletionHandler:] check&reconnect: create a new socket and resume, listen [2023-05-26 20:53:43:083][Callback from URLSession:webSocketTask:didOpenWithProtocol:] Task: LocalWebSocketTask <XYZ>.<1>, didOpenWithProtocol (null) [2023-05-26 20:53:43:083][Call bussinues code ]send push: needPush = 0, message = {"xx":"yy","zz":{"foo":"bar"}} [2023-05-26 20:53:43:083][Call sendPingWithPongReceiveHandler] send ping [2023-05-26 20:53:43:129][Callback from sendPingWithPongReceiveHandler:] receive pong success [2023-05-26 20:53:43:154][Callback from receiveMessageWithCompletionHandler: ]handlerWebSocketTaskError: domain = kNWErrorDomainPOSIX, code = 14 [2023-05-26 20:53:43:154][Call cancel task since we encounter error, ]close&destory LocalWebSocketTask <XYZ>.<1> [2023-05-26 20:53:43:154][Call bussinues code, try to reconnect later]start reconnect(timer: 0x282b9c180) [2023-05-26 20:53:43:154][Callback from URLSession:webSocketTask:didCompleteWithError:] didComplete Task: LocalWebSocketTask <XYZ>.<1> [2023-05-26 20:53:43:154]Callback from URLSession:webSocketTask:didCompleteWithError:] didComplete Error: Error Domain=kNWErrorDomainPOSIX Code=14 "Bad address" UserInfo={NSDescription=Bad address, _NSURLErrorRelatedURLSessionTaskErrorKey=( "LocalWebSocketTask <XYZ>.<1>" ), _NSURLErrorFailingURLSessionTaskErrorKey=LocalWebSocketTask <XYZ>.<1>} ============================================ We have received further information about this issue after viewing more than 25k error reports: Most of the errors are related to network circumstances, like timeouts, which is understandable. 0.3% of devices are reporting a "bad address" error from "receiveMessageWithCompletionHandler:" and "sendMessage:completionHandler:". 95% of the devices reporting a "bad address" are equipped with iOS 13.x. ============================================ We are planning to use the old websocket implementation on iOS 13 instead of NSURLSessionWebSocketTask if we could not address this issue. :p Thansk for paying attention to this issue :)

Cool, I had retry it on iOS 15 beta2, it just works like a charm~

The definition of ITEM list below, could you see  any problem here? @J0hn class AlbumItem: Hashable {   let albumURL: URL   let albumTitle: String   let imageItems: [AlbumDetailItem]   init(albumURL: URL, imageItems: [AlbumDetailItem] = []) {     self.albumURL = albumURL     self.albumTitle = albumURL.lastPathComponent.displayNicely     self.imageItems = imageItems   }   func hash(into hasher: inout Hasher) {     hasher.combine(identifier)   }   static func == (lhs: AlbumItem, rhs: AlbumItem) -> Bool {     return lhs.identifier == rhs.identifier   }   private let identifier = UUID() } BTW, those unnecessary calling  occurs in  demo on session 10252，to reproduce this issue: add delegate for the collection view, disable prefetching to reduce logs:   private func configureHierarchy() {         collectionView = UICollectionView(frame: view.bounds, collectionViewLayout: createLayout())         collectionView.autoresizingMask = [.flexibleWidth, .flexibleHeight]         collectionView.backgroundColor = .systemBackground //        collectionView.prefetchDataSource = self         collectionView.isPrefetchingEnabled = false         collectionView.delegate = self         view.addSubview(collectionView)     } 2.  implement the selection callback for removing item from snapshot: extension PostGridViewController: UICollectionViewDelegate {     func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {         print("remove items at section:(\(indexPath.section)), item:(\(indexPath.item))")         var snapshot = dataSource.snapshot()         let identfiers = snapshot.itemIdentifiers(inSection: Section.ID.allCases[indexPath.section])         snapshot.deleteItems([identfiers[indexPath.item]])         dataSource.apply(snapshot, animatingDifferences: false)     } } finally, remove reload stuff in cell registeration:  let cellRegistration = UICollectionView.CellRegistration<DestinationPostCell, DestinationPost.ID> { [weak self] cell, indexPath, postID in             guard let self = self else { return }             print("configure DestinationPostCell:(\(Unmanaged.passUnretained(cell).toOpaque())) at section:(\(indexPath.section)), item:(\(indexPath.item))")             let post = self.postsStore.fetchByID(postID)             let asset = self.assetsStore.fetchByID(post.assetID)             cell.configureFor(post, using: asset)         } THEN I ran this demo and clicked the first item to remove it, similar log came out: configure DestinationPostCell:(0x000000015ef11940) at section:(0), item:(0) configure DestinationPostCell:(0x000000015ed20410) at section:(0), item:(1) configure DestinationPostCell:(0x000000015ed21900) at section:(1), item:(0) remove items at section:(0), item:(0) configure DestinationPostCell:(0x000000015ed433c0) at section:(1), item:(2) configure DestinationPostCell:(0x000000015ed433c0) at section:(0), item:(0) configure DestinationPostCell:(0x000000015ed433c0) at section:(1), item:(0) configure DestinationPostCell:(0x000000015ed433c0) at section:(1), item:(1) configure DestinationPostCell:(0x000000015ef11940) at section:(1), item:(1)
