I'm developing a Multiplatform app that uses CloudKit to sync the CoreData between the user's devices. At this time they don't share data between users. I have a single password field on a single Entity and was wondering if there was a simple way to encrypt just this field. I see in CoreData there's a checkbox labelled "Allows Cloud Encryption"... does checking that off magically encrypt it. I checked it off and nothing seemed to change so I unchecked it for now... is there something else I needed to do? And, most importantly, will it work with CloudKit?

Hi, I'm updating my app from CoreData to SwiftData and came across an issue. My app has multiple users so in CoreData and I assigned each a myID value set to an UUID so I could use UserDefaults to set the preferred user on app load. When switching over I noticed the PersistentIdentifier value and got excited as I could fetch the matching entity with modelContext.model(for: yourID). I decided to use that instead so I updated my UserDefaults code from UUID to this: @Published var selectedUserID: PersistentIdentifier? { didSet { UserDefaults.standard.set(selectedUserID, forKey: "selectedUserID") } } init() { self.selectedUserID = UserDefaults.standard.object(forKey: "selectedUserID") as? PersistentIdentifier ?? nil } This code compiles and, of course the id is currently set to nil. My issue now is when I try to assign a user to it ar my app crashes and I get the following error: Attempt to set a non-property-list object SwiftData.PersistentIdentifier(id: SwiftData.PersistentIdentifier.ID(url: x-coredata://6FE80FC9-0B4C-491E-8093-DED37A619F1B/EnteredUser/p834), implementation: SwiftData.PersistentIdentifierImplementation) as an NSUserDefaults/CFPreferences value for key selectedUserID Should I go back to an additional UUID field in my user model and find it that way or is there a way to use the PersistentIdentifier value with my UserDefaults? Thanks for any tips.

I have a bug I've come across since I've upgraded Xcode (16.0) and macOS (15.0 Sequoia) and figured I'd create a minimal viable example in case someone else came across this and help. I've noticed this in both the macOS and iOS version of my app when I run it. Essentially I have an area of my code that calls a class that has a step 1 and 2 process. The first step uses async let _ = await methodCall(...) to create some SwiftData items while the second step uses a TaskGroup to go through the created elements, checks if an image is needed, and syncs it. Before this worked great as the first part finished and saved before the second part happened. Now it doesn't see the save and thus doesn't see the insertions/edits/etc in the first part so the second part just isn't done properly. Those step one changes are set and shown in the UI so, in this case, if I run it again the second part works just fine on those previous items while any newly created items are skipped. I came across this issue when step one handled 74 inserts as each one didn't contain an image attached to it. When I switched the async let _ = await methodCall(...) to a TaskGroup, hoping that would wait better and work properly, I had the same issue but now only 10 to 30 items were created from the first step. Minimal Viable Example: to reproduce something similar In my minimal viable sample I simplified it way down so you can't run it twice and it's limited it creating 15 subitems. That said, I've hooked it up with both an async let _ = await methodCall(...) dubbed AL and a TaskGroup dubbed TG. With both types my second process (incrementing the number associated with the subissue/subitem) isn't run as it doesn't see the subitem as having been created and, when run with TaskGroup, only 12 to 15 items are created rather that the always 15 of async let. Code shared here: https://gist.github.com/SimplyKyra/aeee2d43689d907d7a66805ce4bbf072 And this gives a macOS view of showing each time the button is pressed the sub issues created never increment to 1 while, when using TaskGroup, 15 isn't guaranteed to be created and remembered. I'm essentially wondering if anyone else has this issue and if so have you figured out how to solve it? Thanks

Hi, First year receiving revenue through Storekit subscriptions. I live in the United States and know I need to pay taxes within the U.S. for my revenue. I'm curious if I have to handle anything (taxes, etc) in each country I sold a subscription in or does Apple handle all that for me? If it's a per-country basis is there a list somewhere so I can use it to choose where I should offer my app in the future? Thanks everyone!

I am currently running Xcode Version 14.0 beta (14A5228q) creating a Multiplatform app. I wanted to include a LaunchScreen so added a Launch Screen Storyboard to my project. To the the app to see it I went under Target for my app, General, and under App Icons and Launch Screen I set the Launch Screen File to my storyboard. This works perfectly when I run the app on iOS; however, when I run it on macOS I get an error:Launch Screen.storyboard error build: iOS storyboards do not support target device type "Mac". I see there's no way to differentiate between macOS and iOS with the file and there's only one target. Does anyone know a way to make the storyboard only launch when running the iOS app (and iPadOS) and not be seen when running macOS? Thanks

Yesterday I had issues with my CoreData database for my Multiplatform app which resulted in changes to the schema. I reset the CloudKit version and, on the iOS simulator, had to delete my app and run the code again to get it to work. My issue is with the macOS target. I'm getting the same fatalError (Fatal error: Unresolved error Error Domain=NSCocoaErrorDomain Code=134140 "Persistent store migration failed, missing mapping model.") when running the macOS app but I can't figure out how to delete it so I can run it fresh like I did with the iOS version. I've found where the application is created (in the Debug directory ultimately within my app's Build directory) and removed them all but when run the newly created application has the same error. Should I move up the directory structure and remove the entire app directory within Xcode/DerivedData or is there another way? Wanted an answer before I do something I can't go back from :) Thanks, Kyra

I'm currently hooking up StoreKit2 to my app. I worked my way through an older example that listened to products and added/removed ids as they came up. This example fell short using the StoreKit config file as all subscriptions don't have a revocation date set so my list of purchased ids just grew longer (as they weren't removed). My app is only using a single subscription group and thus will only have one subscription live at once. I'm currently grabbing the current subscription using for await result in Transaction.currentEntitlements and am showing the subscriptions with StoreView(ids: arrayIds) and SubscriptionStoreView(groupID: subscriptionGroupID) depending where they user is. Currently when those views disappear I grab the current subscription again (thus updating it if it was changed). That seems cumbersome especially if it doesn't need to be updated and I'm not getting the following error: Making a purchase without listening for transaction updates risks missing successful purchases. Create a Task to iterate Transaction.updates at launch.. I'm wondering if there's a way to just listen to the StoreKit Subscription ID in my main App entry point thus making the final error disappear and maybe, if I could update the type of subscription, removing my onDisappear subscription fetches throughout the rest of the app. All the examples I come across seem to be either tied up with SwiftData (WWDC 2023) or older and maybe not applicable anymore. Everything seems to be embedded in StoreKit and it would be lovely if I could listen in one simple spot for in app and outside app subscription changes. Thanks :)

I've added a package to my Mutliplatform project (Shout) that is now causing an error. When I attempt to build my program on my MacOS Ventura I get a warning "Could not find or use auto-linked library zlib" and six errors about undefined symbols from the zlib library: _deflate, _deflateEnd, _deflateInit_, _inflate, _inflateEnd, and _inflateInit_ I've added paths to my target's Build Settings under Library Search Paths and it doesn't seem to help. Has any one seen anything like this and can help me build the project? It was working with the previous version of my app on the previous stable version. I am running the beta Ventura with the new Xcode version and started a new app to move my code over in parts.
