“SwiftData inheritance relationship”

I have a simple app that uses SwiftUI and SwiftData to maintain a database. The app runs on multiple iPhones and iPads and correctly synchronises across those platforms. So I am correct setting Background Modes and Remote Notifications. I have also correctly setup my Model Configuration and ModelContainer (Otherwise I would expect syncing to fail completely). The problem arises when I run on a Mac (M1 or M3) either using Mac Designed for iPad or Mac Catalyst. This can be debugging in Xcode or running the built app. Then the app does not reflect changes made in the iPhone or iPad apps unless I follow a specific sequence. Leave the app, (e.g click on a Finder window), then come back to the app (i.e click on the app again). Now the app will show the changes made on the iPhone/iPad. It looks like the app on the Mac is not processing remote notifications when in the background - it only performs them when the app has just become active. It also looks like the Mac is not performing these sync operations wh

Hello guys, this is my first post to this forum and really hope that somebody can help me here. I would highly appreciate every help! I am writing my first app with Swift UI (never used UIKit before) which I want to publish later on. This is also my first app which has CoreData implemented. For example I use the following entities: Family, Person 1 Persons can have 1 Family 1 Family can have many Persons My App is structured as the following: ContentView: Contains a TabView with 2 other views in it. A Settings View and a View with a LazyVGrid. LazyVGrid View: This View shows a GridItem for every Family. I get the Families with the following Fetchrequest: @Environment(.managedObjectContext) private var viewContext // These are the Families from the FetchRequest @FetchRequest(entity: Family.entity(), sortDescriptors: [NSSortDescriptor(keyPath: Family.created, ascending: false)] ) var families: FetchedResults Every GridItem is linking to a FamilyDetailView via NavigationLink. So i pass the family as the followin

Hello Developer Support, I have the following code and the following crash. How can the swift data model unable to decode and yet able to display the decoded value at the same time?! What's missing here? CODE: @Model final class DisplayCache { init(point: MKMapPoint) { self.point = point } var point: MKMapPoint } CRASH SwiftData/ModelCoders.swift:1069: Fatal error: Unable to decode this value MKMapPoint(x: 74358466.66307731, y: 97927933.41833577)

I'm working on a new app with SwiftData and now adding CloudKit Sync. Everything is working fine in the simulator against the development CloudKit Schema. I successfully deployed the schema to production. However, the TestFlight builds fail against production. This is what I see in the logs, but I haven't been able to find info on how to fix it. Help appreciated.

Hi all, In my SwiftUI / SwiftData / Cloudkit app which is a series of lists, I have a model object called Project which contains an array of model objects called subprojects: final class Project1 { var name: String = @Relationship(deleteRule: .cascade, inverse: Subproject.project) var subprojects : [Subproject]? init(name: String) { self.name = name self.subprojects = [] } } The user will select a project from a list, which will generate a list of subprojects in another list, and if they select a subproject, it will generate a list categories and if the user selects a category it will generate another list of child objects owned by category and on and on. This is the pattern in my app, I'm constantly passing arrays of model objects that are the children of other model objects throughout the program, and I need the user to be able to add and remove things from them. My initial approach was to pass these arrays as bindings so that I'd be able to mutate them. This worked for the most part but

I'm implementing SwiftData with inheritance in an app. I have an Entity class with a property name. This class is inherited by two other classes: Store and Person. The Entity model has a one-to-many relationship with a Transaction class. I can list all my Entity models in a List with a @Query annotation without a problem. However, then I try to access the name property of an Entity from a Transaction relationship, the app crashes with the following error: Thread 1: Fatal error: Never access a full future backing data - PersistentIdentifier(id: SwiftData.PersistentIdentifier.ID(backing: SwiftData.PersistentIdentifier.PersistentIdentifierBacking.managedObjectID(0x96530ce28d41eb63 ))) with Optional(F07E7E23-F8F0-4CC0-B282-270B5EDDC7F3) From my attempts to fix the issue, I noticed that: The crash seems related to the relationships with classes that has inherit from another class, since it only happens there. When I create new data, I can usually acces
