I have read that localStorage is a temporary data function(I didn’t even know that since iOS 5.1…) and I was surprised that it deleted all data. Anyways, is it a way to make be there as long as user wants(like on Windows or other devices)? Also here’s link to code that are on GitHub.

I have an app for client management that stores data in Core Data with an NSPersistentCloudKitContainer. Each manager have their clients in the Core Data Private Database, and each client could have associated files (images, documents, etc) that are stored in app's own folder structure in iCloud Drive. Eventually, a manager can decide if to share a client with another manager, in order to have a shared managed client (readable, or writable+readable by others managers which share the same client). This is done by moving the Client from the Private Database to the Shared Database following the Apple's guidelines: https://developer.apple.com/videos/play/wwdc2021/10015/ This is the structure: The problem is: the database record is shared correctly, but the iCloud Drive Files are not shared (obviously). My goal is to get working the iCloud Drive Client Files (every client has a single Folder) with the minimum effort from the user. I cannot get working the iCloud Drive Sharing from my app, only the Core Data Sharing, so (in development environment) I have to share the Client Core Data Info from the App sheet, and then, go to Finder and share the Client's folder and send the link, so it would be a bit confusing for my users. Any approach for get working iCloud Drive File Sharing from the (inside) my app? Generate a link and automatically send to the other user. Or, better, an approach to get working this sharing with a single action from the user (only share once, and it sends the core data info and icloud drive file sharing).

My first iOS/WatchOs app was rejected for "Specifically, iPhone app does not sync with Apple Watch". But it does sync data through the Apple CloudKit. Should my app support both AppGroup and CloudSync of my CoreData container? If yes, how this is possible? If not, shall I just resubmit the same app and add explanation that app does support CloudSync and attach video evidence?

Hi! I am developing Auto Backup Applicaiton with Flutter UI Framework, I successfully acheived my target with Android, but I'm not able to acheive on iOS. Kindly guide me, how can i fetch photos and files apps directory paths?

Hi Team, i am facing a strange issue in my iOS game where the local data gets resets for quite few times a day when the game is resumed from background. This causes the game preferences reset and other local data saved by plugins. Any hint on Xcode projects settings, entitlements settings required to avoid this issue?

Is there a limit for local storage for Safari? If there is, is there a way to increase the local storage limit?

Hello everyone, in the App I'm building I'd like to share an entire list of items (records) by just sharing the list itself (parent record or RecordZone). Meanwhile, I'd like to continue using the NSPersistentCloudKitContainer and therefore CoreData sync. Is it possible, with the new features Apple introduced (Sharing RecordZone and Sharing in Cloud & Local Storage), to do what I described, and combine both functions. Thank you, Carlos Steiner

I am making a video sharing app and I am looking for a good cloud storage service that I can upload my videos to and store them. I was previously using Firebase Cloud to store my videos, but I ran into a problem with Firebase and decided it will not work for what I am trying to do. So I decided to switch my cloud storage and I am having a hard time finding something that will work. Question: What are some good cloud storage options for storing videos? Or is there a better way to store videos other than a cloud storage service? The app is very similar to Youtube and the average video length will be around 10 mins if that helps at all. P.S The problem I am having with Firebase storage is that the videos never get uploaded to Firebase if the user closes out of the app during the upload. None of the IOS background options work either.BGProcessingTask and URLSessionUploadTask do not work to finish uploading the video in the background because Firebase does not allow you to pausing uploading during sessions to finish BGProcessingTask, and Firebase does not give you a URL to upload the video to finish URLSessionUploadTask.

I am running the WWDC21 sample application "CoreDataCloudkitDemo" with two different Apple IDs to test the Cloudkit sharing feature. I use two simulators and one real device, where the latter has the same ID as one of the simulators. While creating invites via "Copy link" works on all three installations, accepting invites only works on the real device. Trying to open an invite (by copying the link in the one and pasting it into Safari in the other) always results in a web page stating that "iCloud has stopped responding" and "Unable to find applicationIdentifier for the containerId = [my ID] and fileExtension = undefined". Is this a simulator bug in Xcode 13.2 or is there anything I can do about it? Other iCloud features (including login via Safari to icloud.com) work in both simulators. Is there a way to open invite URLs in a simulator (as there is no functioning iMessage or Mail app) other than Safari's URL input field? Doing so does not work in the real device either, but clicking it in e.g. iMessage works. Edit: Pasting the link into a ToDo item and opening it from there works even in the simulator - so is it just a Safari issue?

Hi, I wanted to offer the UI for editing and deleting a share. So for using UICloudSharingController(share: , container: ) I implemented the delegate to call "persistUpdatedShare" in "cloudSharingControllerDidSaveShare" func cloudSharingControllerDidSaveShare(_ csc: UICloudSharingController) { if let share = csc.share,   let privatePersistentStore = PersistenceController.shared.privatePersistentStore { PersistenceController.shared.container.persistUpdatedShare(share, in: privatePersistentStore) { (share, error) in Thread.performOnMain { if let error = error { PersistenceController.shared.storeWarning = error } } } } } and to call "purgeObjectsAndRecordsInZone" in "cloudSharingControllerDidStopSharing" func cloudSharingControllerDidStopSharing(_ csc: UICloudSharingController) { let puzzleToShare = puzzleToShare if let share = csc.share,   let privatePersistentStore = PersistenceController.shared.privatePersistentStore { PersistenceController.shared.container.purgeObjectsAndRecordsInZone(with: share.recordID.zoneID, in: privatePersistentStore) { (zoneID, error) in Thread.performOnMain { if let error = error { PersistenceController.shared.storeWarning = error } else { puzzleToShare.makePrivateDuplicate() try? puzzleToShare.puzzle.managedObjectContext?.save() } } } } } I got this implementation from a TSI, but it makes no sense to me to delete and duplicate my objects rather than just keeping them and only deleting the share. Question: How can I cleanly discontinue a share, but keep my data. Duplicating my objects seems such a weird approach. But without this implementation it does not really work. (I get strange behaviors and crashes) All the best Christoph

Please tell me if there is any recommended method of persisting data (app token - string type) through app reinstallation. With the answer from: https://developer.apple.com/forums/thread/36442?answerId=281900022#281900022 The suggestion of using DeviceCheck is not working for me since DeviceCheck will generate a random token, and with that token, our backend can only request for two bits. Storing data on a device keychain will have an indeterministic future but seems like it's the only viable option for now.

Hello I'm developing Simple memo-app This memo-app supports iCloud synchronization(default) I want to notify the user, it who has a lack of iCloud capacity. But, I do not know how to know the capacity of the user's iCloud in my app. (this app used Cloudkit(PersistentCloudKitContainer).) I have any way to know user's iCloud capacity in the iOS app? or I want to know, How much iOS App is occupying the user's iCloud. I would like to know the user's iCloud remaining space. I would like to know iOS App is How much occupying the user's iCloud.

Hi guys, Never come across this issue when I switch to a new 2021 MBP 14" M1PRO.(base setup) Happens quite often when I'm saving my blender file, pops up an error saying not enough space. (where after migration I should have about 250GB still.) After going through the storage management tab I came across the " Library - Caches - Cloudkit - com.apple.bird" is eating up 251 GB of storage. I've tried to delete the folder, it pops back right away. and gradually increase it's size till it's full again. Strangely, if I leave the laptop overnight, sometimes the storage will clean up by itself again. Yet, it will continue a behavioral loop on daily basis to a point it's not useable for a new MBP. Does anyone have any idea what it could be or any solutions? greatly appreciated!!

I have a cloud storage app. Right now, saving files into it creates my app's folder in On my iPhone. Is it possible to have my app's folder outside of it, in Files app's Locations list? Just like I have other cloud providers like Dropbox, OneDrive etc(see image).

I'm trying to build an educational SwiftUI iOS app with course videos. I've tried storing these videos on YouTube as private videos and also Vimeo. But they both show the video controls which allows the URL to be extracted, which I don't want. Storing the videos as a local resource is a no no otherwise the app would be several gb's. I can also store the videos just on my web hosting, but again I think these are discoverable and I don't want to go down the route of creating log ins and user accounts. Are there any other solutions of doing this? Is it possible to store the videos in Firebase and get the app to access them stored there?

Hi. I want to make a planner app that has the date and location of the project. Only I have a problem. I used a "DatePicker" so that the date is counted. Only I do not know how to save and display the selected date. In general I have problems to save and reload the content of the variables and texfielders etc. I thought that these contents are automatically saved on the end device of the user. I have read that there are methods like "UserDefaults", "CoreData" or "AppStorage". Have been reading stuff about this forever. But I can't get this to work. I hope someone would like to donate their time to help. Greetings Janik

We are developing an Apple Arcade title. I have a question about data storage on tvOS. iOS and Mac can use his GKSavedGame, but tvOS cannot. https://developer.apple.com/documentation/gamekit/gksavedgame?language=objc At tvOS, we are considering using iCloud Key Value Storage or CloudKit. Are these available on Apple Arcade? Also, could you please tell me if there is a standard way to do cloud saves on Apple Arcade?
