After the problems with the ModelActor in iOS 18, it seemed like the ModelActor became more stable with iOS 18.1 and macOS 15.1. However, I’m still encountering many problems and crashes. I wanted to ask if these issues are related to my persistence layer architecture or if they’re still inherent to the ModelActor itself. I’ve generally followed the blog posts: https://fatbobman.com/en/posts/practical-swiftdata-building-swiftui-applications-with-modern-approaches/ and https://brightdigit.com/tutorials/swiftdata-modelactor/ and aim to achieve the following: I have a single DataProvider that holds the ModelContainer and uses it to configure and initialize a single DataHandler. These are created once at app launch and injected into the SwiftUI view hierarchy as EnvironmentObjects. Since I need to access the SwiftData models not only in SwiftUI but also indirectly in ViewModels or UIKit views, all read operations on the models should go through the DataProvider ( ModelContainrs MainContext), while all other CRUD operations are handled centrally via the single DataHandler (executed within a single ModelActor). Additionally, I want to monitor the entire container using another ModelActor, initialized in the DataProvider, which tracks changes to objects using TransactionHistory. I’ve managed to implement this to some extent, but I’m facing two main issues: ModelActor and Main Actor Requirement The ModelActor only updates SwiftUI views when initialized via the main context of the ModelContainer and therefore runs on the Main Actor. It would be ideal for this to work in the background, but the issue with the ModelActor that existed previously doesn’t seem to have been resolved in iOS 18.1/macOS 15.1—am I wrong about this? Frequent Crashes (more severe) Crashes occur, especially when multiple windows on macOS or iPadOS access the same DataHandler to update models. This often leads to crashes during read operations on models by a SwiftUI view, with logs like: Object 0x111f15480 of class _ContiguousArrayStorage deallocated with non-zero retain count 3. This object's deinit, or something called from it, may have created a strong reference to self which outlived deinit, resulting in a dangling reference. error: the replacement path doesn't exist: "/var/folders/gs/8rwdjczj225d1pj046w3d97c0000gn/T/swift-generated-sources/@__swiftmacro_12SwiftDataTSI3TagC4uuID18_PersistedPropertyfMa_.swift" Can't show file for stack frame : <DBGLLDBStackFrame: 0x34d28e170> - stackNumber:1 - name:Tag.uuID.getter. The file path does not exist on the file system: /var/folders/gs/8rwdjczj225d1pj046w3d97c0000gn/T/swift-generated-sources/@__swiftmacro_12SwiftDataTSI3TagC4uuID18_PersistedPropertyfMa_.swift This error usually happens when there are multiple concurrent accesses to the DataHandler/ModelActor. However, crashes also occur sporadically during frequent accesses from a single view with an error like "the replacement path doesn't exist." It also seems like having multiple ModelActors, as in this case (one for observation and one for data changes), causes interference and instability. The app appears to crash less frequently when the observer is not initialized, but I can’t verify this—it might just be a coincidence. My Question: Am I fundamentally doing something wrong with the ModelActors or the architecture of my persistence layer?

Looking at my CloudKit Telemetry console I noticed a significant increase in 'Other' errors recently. These errors are impacting user experience and I really don't know how to better understand the issues that may be occurring due to the "other" category. If I query the logs for "other" errors, only 2 results show up for the week. There are 2500+ errors in the telemetry graph (see attached). Is anyone else experiencing this or does anyone have a suggestion on how I can better understand this issue? Thank you!

Hi everyone, I have an application that allows to share Core Data records through CKShare. If I compile the app in debug or release mode on my devices with Xcode the Sharing functionality work like a charm, but if I download the application from App Store doesn't work, It seems that can't generate the link for sharing. Does anyone have any idea why? Thanks

Здравствуйте, я зашел на чужой Apple ID под предлогом мошенников и теперь не могу выйти, помогите мне пожалуйста, это полностью мой телефон и я смогу доказать, что он мой.

Something has caused my CloudKit queries to fail. On the dashboard I get an error message "Failed to execute query" when I try to "SORT BY" a field. The field is listed under Indexes as "sortable". For a different field, when I enter the field under "FILTER BY", and before I tap "Query", I get "No results". That field is listed under the Indexes as "queryable". It used to work fine. I have described this further, with screenshots at FB16114560

Hello the documentation for message filtering has been offline for a few days now, is it possible to get it back, or is there somewhere else it can be viewed in the meanwhile? https://developer.apple.com/documentation/sms_and_call_reporting/sms_and_mms_message_filtering (I just chose topic/tags at random, there aren't any relevant for this)

Hi, I'm building a habit tracking app for iOS and macOS. I want to use up to date technologies, so I'm using SwiftUI and SwiftData. I want to store user data locally on device and also sync data between device and iCloud server so that the user could use the app conveniently on multiple devices (iPhone, iPad, Mac). I already tried SwiftData + NSPersistentCloudKitContainer, but I need to control when to sync data, which I can't control with NSPersistentCloudKitContainer. For example, I want to upload data to server right after data is saved locally and download data from server on every app open, on pull-to-refresh etc. I also need to monitor sync progress, so I can update the UI and run code based on the progress. For example, when downloading data from server to device is in progress, show "Loading..." UI, and when downloading finishes, I want to run some app business logic code and update UI. So I'm considering switching from NSPersistentCloudKitContainer to CKSyncEngine, because it seems that with CKSyncEngine I can control when to upload and download data and also monitor the progress. My database schema (image below) has relationships - "1 to many" and "many to many" - so it's convenient to use SwiftData (and underlying CoreData). Development environment: Xcode 16.1, macOS 15.1.1 Run-time configuration: iOS 18.1.1, macOS 15.1.1 My questions: 1-Is it possible to use SwiftData for local data storage and CKSyncEngine to sync this local data storage with iCloud? 2-If yes, is there any example code to implement this? I've been studying the "CloudKit Samples: CKSyncEngine" demo app (https://github.com/apple/sample-cloudkit-sync-engine), but it uses a very primitive approach to local data storage by saving data to a JSON file on disk. It would be very helpful to have the same demo app with SwiftData implementation! 3-Also, to make sure I don't run into problems later - is it okay to fire data upload (sendChanges) and download (fetchChanges) manually with CKSyncEngine and do it often? Are there any limits how often these functions can be called to not get "blocked" by the server? 4-If it's not possible to use SwiftData for local data storage and CKSyncEngine to sync this local data storage with iCloud, then what to use for local storage instead of SwiftData to sync it with iCloud using CKSyncEngine? Maybe use SwiftData with the new DataStore protocol instead of the underlying CoreData? All information highly appreciated! Thanks, Martin

I really don't understand what kind of cyber crap CloudKit is! In macOS, CloudKit basically doesn’t work properly

I am trying to implement record sharing in my project, but when I try to copy the link on the UICloudSharingController, the sheet closes and the link doesn't get copied. My CloudKitManager function: public func shareTeam(_ team: Team) -> AnyPublisher<CKShare, Error> { Future { [weak self] promise in guard let self = self else { promise(.failure(CloudKitError.unknown)) return } let record = team.toCKRecord() let share = CKShare(rootRecord: record) share[CKShare.SystemFieldKey.title] = "Join \(team.name)" as CKRecordValue share.publicPermission = .readWrite let operation = CKModifyRecordsOperation(recordsToSave: [record, share], recordIDsToDelete: nil) operation.savePolicy = .ifServerRecordUnchanged operation.qualityOfService = .userInitiated operation.modifyRecordsResultBlock = { result in switch result { case .success: promise(.success(share)) case .failure(let error): promise(.failure(error)) } } self.privateDatabase.add(operation) } .eraseToAnyPublisher() } ViewModel function: func shareTeam() { guard let selectedTeam = selectedTeam else { return } CloudKitManager.shared.shareTeam(selectedTeam) .receive(on: DispatchQueue.main) .sink { [weak self] completion in switch completion { case .finished: break case .failure(let error): self?.didError = true self?.error = error } } receiveValue: { share in let sharePresenter = SharePresenter( share: share, container: CloudKitManager.shared.container, teamName: selectedTeam.name, rootRecord: selectedTeam.toCKRecord() ) sharePresenter.presentShareSheet() } .store(in: &cancellables) }

throughout all of Foundation's URL documentation, its called out in multiple places that data stored inside an app sandox's caches directory doesn't count towards data and documents usage in the settings app but in practice, it looks like storing data there does in fact count towards documents & data for the app i'm trying to understand if the docs are wrong, if theres a bug in the settings app, or if this is a mistake on my part

is there a way to fix this?

Is it ok to have latency about 4 sec? The amount of downloaded data is less than 1 MB. Maybe I need to setup an index for every field requested?

When attempting to deploy schema changes in the iCloudKit Database by clicking the Deploy Schema Changes button, a Confirm Deployment dialog appears, showing an error: “Internal error”.

Hi everyone, I am a beginner in iOS/Swift programming. I'm trying to develop a mobile application that allows to mount a network drive in the iphone Files application via the WebDav protocol. I saw on the internet that WebDav is no longer implemented in iOS because considered deprecated by apple. To accomplish this task, I decided to separate responsibilities as follows: Framework: WebDav (responsible for communication with the WebDav server) FileProviderExtension: FileBridge (Responsible for bridging the gap between the WebDav Framework and the iOS Files app) Main App I also have an AppGroup that includes the main application and the fileproviderextension Initially, to measure the feasibility and complexity of this task, I'd like to make a simplistic version that simply displays the files on my drive in the Files app, without necessarily being able to interact with them. FileProviderExtension.swift: import FileProvider import WebDav class FileProviderExtension: NSObject, NSFileProviderReplicatedExtension { private var webDavService: WebDavService? required init(domain: NSFileProviderDomain) { super.init() self.webDavService = WebDavService(baseURL: URL(string: "https://www.mydrive.com/drive")!) } func invalidate() { // TODO: cleanup any resources } func item(for identifier: NSFileProviderItemIdentifier, request: NSFileProviderRequest, completionHandler: @escaping (NSFileProviderItem?, Error?) -> Void) -> Progress { let progress = Progress(totalUnitCount: 1) Task { do { if let items = try await webDavService?.propfind(path: identifier.rawValue, depth: 1), let item = items.first(where: { $0.itemIdentifier == identifier }) { completionHandler(item, nil) } else { completionHandler(nil, NSError(domain: NSCocoaErrorDomain, code: NSFileNoSuchFileError, userInfo: nil)) } } catch { completionHandler(nil, error) } } return progress } func fetchContents(for itemIdentifier: NSFileProviderItemIdentifier, version requestedVersion: NSFileProviderItemVersion?, request: NSFileProviderRequest, completionHandler: @escaping (URL?, NSFileProviderItem?, Error?) -> Void) -> Progress { let progress = Progress(totalUnitCount: 1) Task { do { guard let service = webDavService else { throw WebDavError.invalidResponse } let data = try await service.get(fileAt: itemIdentifier.rawValue) let tempURL = FileManager.default.temporaryDirectory.appendingPathComponent(itemIdentifier.rawValue) try data.write(to: tempURL) completionHandler(tempURL, nil, nil) } catch { completionHandler(nil, nil, error) } } return progress } func createItem(basedOn itemTemplate: NSFileProviderItem, fields: NSFileProviderItemFields, contents url: URL?, options: NSFileProviderCreateItemOptions = [], request: NSFileProviderRequest, completionHandler: @escaping (NSFileProviderItem?, NSFileProviderItemFields, Bool, Error?) -> Void) -> Progress { // TODO: a new item was created on disk, process the item's creation completionHandler(itemTemplate, [], false, nil) return Progress() } func modifyItem(_ item: NSFileProviderItem, baseVersion version: NSFileProviderItemVersion, changedFields: NSFileProviderItemFields, contents newContents: URL?, options: NSFileProviderModifyItemOptions = [], request: NSFileProviderRequest, completionHandler: @escaping (NSFileProviderItem?, NSFileProviderItemFields, Bool, Error?) -> Void) -> Progress { // TODO: an item was modified on disk, process the item's modification completionHandler(nil, [], false, NSError(domain: NSCocoaErrorDomain, code: NSFeatureUnsupportedError, userInfo:[:])) return Progress() } func deleteItem(identifier: NSFileProviderItemIdentifier, baseVersion version: NSFileProviderItemVersion, options: NSFileProviderDeleteItemOptions = [], request: NSFileProviderRequest, completionHandler: @escaping (Error?) -> Void) -> Progress { // TODO: an item was deleted on disk, process the item's deletion completionHandler(NSError(domain: NSCocoaErrorDomain, code: NSFeatureUnsupportedError, userInfo:[:])) return Progress() } func enumerator(for containerItemIdentifier: NSFileProviderItemIdentifier, request: NSFileProviderRequest) throws -> NSFileProviderEnumerator { return FileProviderEnumerator(enumeratedItemIdentifier: containerItemIdentifier, service: webDavService) } } Here's the code I use to initialize my domain in the main app files: fileprivate func registerFileProviderDomain() { let domainIdentifier = NSFileProviderDomainIdentifier("FileProviderExtension Bundle Identifier") let domain = NSFileProviderDomain(identifier: domainIdentifier, displayName: "My Drive") NSFileProviderManager.add(domain) { error in NSFileProviderManager.add(domain) { error in if let error = error { print("Error cannot add domain file provider : \(error.localizedDescription)") } else { print("Success domain file provider added") } } } I can't get rid of the Error : Error cannot add domain file provider : The operation couldn’t be completed. Invalid argument. I don't know what I'm missing Please help me understand

Hello, on every Apple device, iPhone/Watch I have the option to install developer beta versions. I would like to unsubscribe from developer beta versions - not have them in settings. I know that developer beta is assigned to my iCloud account. After logging out and restoring factory settings, the tab disappears. When I log into my iCloud account, it appears everywhere. I did not sign up for developer beta. How do I remove it?

Hello, I apologize if this post could be slightly out of forum topic but I have one issue that I cannot solve. I tried a few times to call Apple support but the only indication that have given to me is to try with this forum. The issue I have is simple. Sometimes the modifications performed on iCloud Drive on one computer are not properly synced between the local folder /Users/[username]/Library/Mobile Documents/... and the cloud and therefore are not shared across all devices that use the same iCloud Drive. This is very disturbing as it may lead to a data loss. I would like to write a simple software that activates the iCloud Drive sync between the local iCloud folder /Users/[username]/Library/Mobile Documents/... and the Cloud. A simple macOS bash script would be fine but also other pieces of software are welcome. Can anyone please help me? Thanks! Daniele

I have integrated CloudKit into a CoreData application and am ready to deploy the schema to production but keep getting an "internal error" when trying to deploy to production or reset my CloudKit environment. I have attached images of what I am seeing including one of the console error. Is there any way to resolve this?
