When I use CloudKit, I want to know some capacity limit infomation. How many CKRecordZone I can create in a database? How many CKRecord I can create in a zone? Thanks.

Hi all, We have an iOS app which has Cloudkit Coredata as storage mechanism. Whenever user logout of iCloud in settings app, then the Coredata is wiped out and no row exists in the tables. Can we prevent this. We want to retain the coredata values until there is another iCloud user logs into settings app. Thanks Vinoth

Hi all I have two mystic issues with saving and fetching data to and from iCloud. Both repro only after first launch of an app. 1. [GKLocalPlayer fetchSavedGamesWithCompletionHandler:] After first attempt I can see 0 saved games (but i know that there is at least one saved game) and there is no any error. In case if I try fetch one more time (without any additional actions) even immediately after first attempt I receive saved games correctly (not 0) 2. [GKLocalPlayer saveGameData: withName: completionHandler:] After first attempt I can see error The requested operation could not be completed because local player has not been authenticated. In case if I try save one more time (without any additional actions) even immediately after first attempt I can save data successfully without any error I found the same issue in StackOverflow, but there are no fixes...

I'm using UIDocumentPickerViewController to open a url. Works fine in debug mode but version on the App Store is failing. Code to create the document picker is like: NSArray *theTypes = [UTType typesWithTag:@"docxtensionhere" tagClass:UTTagClassFilenameExtension conformingToType:nil]; UIDocumentPickerViewController *documentPicker = [[UIDocumentPickerViewController alloc]initForOpeningContentTypes:theTypes]; documentPicker.delegate = self;   [self presentViewController:documentPicker animated:YES completion:nil]; So in debug mode this is all gravy. -documentPicker:didPickDocumentsAtURLs: passes back a URL and I can read the file. In release mode I get a URL but my app is denied access to read the file. After inspecting some logging it appears the sandbox is not granting my app permission. error Domain=NSCocoaErrorDomain Code=257 "The file “Filename.fileextensionhere” couldn’t be opened because you don’t have permission to view it." UserInfo={NSFilePath=/private/var/mobile/Library/Mobile Documents/comappleCloudDocs/Filename.fileextensionhere, NSUnderlyingError=0x2834c9da0 {Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"}} -- If I'm doing something wrong with UIDocumentPickerViewController it is a real shame that permission is not being denied in Debug mode, as devs are more likely to catch in prior to release. Anyone know where I'm going wrong and if not have a workaround? Thanks in advance.

Hi all, I’m trying to use NSMetadataQuery on iOS to track changes to folders users have imported from elsewhere but, no matter what I try, I get no results. Following the documentation for searching file metadata with NSMetadataQuery, I’m creating a live query (albeit in Swift) and listening for […]QueryDidFinishGathering and […]QueryDidUpdate. The former fires, with no results, and the latter never fires. I’ve also tried following the Synchronizing Documents in the iCloud Environment example, adding the appropriate Ubiquity keys to my Info.plist and .entitlements file, with no change. I’m importing files and folders using SwiftUI’s View.fileImporter(isPresented:allowedContentTypes:allowsMultipleSelection:onCompletion:), but can’t see how I might security-scope the NSMetadataQuery’s execution (if that’s even a thing?). My test project is on GitHub, but the main parts are below… My query method: extension NSMetadataQueryUbiquitousExternalDocumentsTestApp { func findAccessibleFiles() { query.stop() fileMonitor?.cancel() fileMonitor = Publishers.MergeMany( [ .NSMetadataQueryDidFinishGathering, .NSMetadataQueryDidUpdate ].map { NotificationCenter.default.publisher(for: $0) } ) .receive(on: DispatchQueue.main) .sink { notification in query.disableUpdates() defer { query.enableUpdates() } foundItems = query.results as! [NSMetadataItem] print("Query posted \(notification.name.rawValue) with results: \(query.results)") } query.searchScopes = [ NSMetadataQueryAccessibleUbiquitousExternalDocumentsScope ] query.predicate = NSPredicate( format: "%K LIKE %@", argumentArray: [NSMetadataItemFSNameKey, "*"] ) query.sortDescriptors = [ NSSortDescriptor(key: NSMetadataItemFSNameKey, ascending: true) ] if query.start() { print("Query started") } else { print("Query didn't start for some reason") } } } Info.plist: […] <key>NSUbiquitousContainers</key> <dict> <key>iCloud.com.stevemarshall.AnnotateML</key> <dict> <key>NSUbiquitousContainerIsDocumentScopePublic</key> <true/> <key>NSUbiquitousContainerName</key> <string>AnnotateML</string> <key>NSUbiquitousContainerSupportedFolderLevels</key> <string>ANY</string> </dict> </dict> […]
