SwiftData public sharing
I have an Apple app that uses SwiftData and icloud to sync the App's data across users' devices. Everything is working well. However, I am facing the following issue: SwiftData does not support public sharing of the object graph with other users via iCloud. How can I overcome this limitation without stopping using SwiftData? Thanks in advance!

Can a ReferenceFileDocument be @Observable?
Although I can't see anything in Apple's documentation to this effect, I'm coming to believe that ReferenceFileDocument is incompatible with @Observable. But hopefully I've just missed something! I have an app in which the data model is @Observable, and views see it through @Environment(dataModel.self) private var dataModel Since there are a large number of views, only some of which may need to be redrawn at a given time, Apple's documentation leads me to believe that @Observable may be smarter about only redrawing views that actually need redrawing than @Published and @ObservedObject. I originally wrote the app without document persistence, and injected the data model into the environment like this: @main struct MyApp: App { @State private var dataModel = DataModel() var body: some Scene { WindowGroup { myDocumentView() .environment(dataModel) } } } I’ve been trying to make the app document based. Although I started using SwiftData, it has trouble with Codable (you need to explicitly code each eleme

Reply to Does Core Spotlight work with document-based apps?
The issue is that Spotlight APIs appear to be App based & not Document based. Sort of. I think the better way to understand this is that the API was intentionally broadened to cover non-document data, but that shift also makes the API appear more app based. I can't find a way to separate Spotlight data by document. Note the contentURL property of CSSearchableItemAttributeSet, which is how you'd note the document location. So you'll end up creating multiple CSSearchableItems for every document, all of which (for a given document) will have the same content URL. I've tried having each document maintain a UUID as a document-specific identifier and include the identifier in every CSSearchableItem. When performing a query I filter the results with CSUserQueryContext.filterQueries that filter by the document identifier. That works to limit results to the specific file for search operations. My guess here is that this is fairly slow, because you're basically searching everything and then discarding results down

Error querying optional Codable with SwiftData
I'm building a SwiftUI app using SwiftData. In my app I have a Customer model with an optional codable structure Contact. Below is a simplified version of my model: @Model class Customer { var name: String = var contact: Contact? init(name: String, contact: Contact? = nil) { self.name = name self.contact = contact } struct Contact: Codable, Equatable { var phone: String var email: String var allowSMS: Bool } } I'm trying to query all the Customers that have a contact with @Query. For example: @Query(filter: #Predicate { customer in customer.contact != nil }) var customers: [Customer] However no matter how I set the predicate I always get an error: BugDemo crashed due to an uncaught exception NSInvalidArgumentException. Reason: keypath contact not found in entity Customer. How can I fix this so that I'm able to filter by contact not nil in my Model?

SwiftData .deny deleteRule not working
I tried to use the .deny deleteRule but it seems to have no effect. The toolbar button adds an item with a relationship to a category to the context. Swiping on the category deletes the category even though an item is referencing the category. There is also no error thrown when saving the context. It is as if the deleteRule was not there. For other deleteRules like .cascade, the provided sample code works as expected. import SwiftUI import SwiftData @Model class Category { var name: String @Relationship(deleteRule: .deny) var items: [Item] = [] init(name: String) { self.name = name } } @Model class Item { var name: String var category: Category? init(name: String, category: Category) { self.name = name self.category = category } } struct DenyDeleteRule: View { @Environment(.modelContext) private var modelContext @Query private var categories: [Category] @Query private var items: [Item] var body: some View { List { Section(Items) { ForEach(items) { item in Text(item.name) } } Section

Cannot select build for version
Hello, In App Store Connect I currently can't seem to select a build version for my next app version in preparation. The popover loads and shows my builds, but all radio buttons are greyed out and not clickable. I only noticed this after I saw that my usual build workflow via fastlane failed with this error: The provided entity includes a relationship with an invalid value - The specified pre-release build could not be added. - /data/relationships/build However I couldn't find any data issue on my side. Is there some ongoing server problem or what might cause this? Thanks, Timo

Creating Advanced AppClip Experiences Via API
I'm trying to programmatically create an Advanced AppClip Experience via the API. following the docs https://developer.apple.com/documentation/appstoreconnectapi/app-clips-and-app-clip-experiences I have created the header image. But when I try to create the experience I can not figure out a) how to create a localisationID to be included in the relationships object b) how to get the included object to be recognised Any one have experience or can offer help?

Reply to NSTableView is unresponsive when inside a modal window shown in DispatchQueue.main.async
Thanks for the explanation. So is using perform(_:with:afterDelay:) or Timer.scheduledTimer(withTimeInterval:repeats:block:) the correct way in this case? I thought using DispatchQueue.main.async was the most elegant way, as it's succinct and allows me to call a native Swift method with a native Swift argument, but because of the modal table view unresponsiveness it's out of the question. Timer.scheduledTimer(withTimeInterval:repeats:block:) is less intuitive and a little longer, but works in this case, so it's my best option for now. perform(_:with:afterDelay:) requires the first argument to be a @objc method, which in turn requires its own argument to be representable in Objective C (which I did by inheriting from NSObject, quite an overhead).

SectionedFetchRequest in SwiftData
With Core Data and SwiftUI we can use @SectionedFetchRequest. Does SwiftData support something similar to @SectionedFetchRequest? For example, I want to create a lazy-loaded list that groups posts by their date. @Model Post { let title: String let dateString: String // YYYY-MM-DD let createdAt: Date } @SectionedFetchRequest( entity: Post.self, sectionIdentifier: Post.dateString, sortDescriptors: [Post.createdAt] ) var postsByDate: SectionedFetchResults ForEach(postsByDate) { section in Section(header: Text(section.id)) { ForEach(section) { post in PostView(post) } } }

'NSInvalidArgumentException', reason: 'Duplicate version checksums across stages detected.'
I have an iOS app using SwiftData with VersionedSchema. The schema is synchronized with an CloudKit container. I previously introduced some model properties that I have now removed, as they are no longer needed. This results in the current schema version being identical to one of the previous ones (except for its version number). This results in the following exception: 'NSInvalidArgumentException', reason: 'Duplicate version checksums across stages detected.' So it looks like we cannot have a newer schema version with an identical content to an older schema version. The intuitive way would be to re-add the old (identical) schema version to the end of the schemas list property in the SchemaMigrationPlan, in order to signal that it is the newest one, and to add a migration stage back to it, thus: public enum MySchemaMigrationPlan: SchemaMigrationPlan { public static var schemas: [any VersionedSchema.Type] { [ SchemaV100.self, SchemaV101.self, SchemaV100.self ] } public static var stages: [MigrationSta

Reply to Autogenerated UI Test Runner Blocked By Local Network Permission Prompt
I ended up trying the last two approaches that I mentioned: Running the CI/CD connector directly from Terminal.app Running the CI/CD connector directly from a local ssh session I figured these last two were the most direct in trying to exercise the listed carve outs in TN3179: Understanding local network privacy | Apple Developer Documentation which states: Command-line tools run from Terminal or over SSH, including any child processes they spawn Between each of these tests I restarted the machine since it seems that that's the only reliable way to reset the state for this mechanism on macOS 15.5. Running directly from Terminal.app Here is an annotated screenshot from running directly from Terminal.app Here is a description of each numbered point of interest in this screenshot: You can see that i'm simply directly executing the script from https://github.com/actions/runner/blob/main/src/Misc/layoutroot/run.sh to run the CI/CD connector.

If it’s UI facing or some SwiftData related, you need to use with @MainActor. but ideally provide more information.

Reply to Error querying optional Codable with SwiftData
Use a separate @Model class Contact instead, works well for me. Even though Contact is Codable in your code, SwiftData does not store it like a model class.
