“SwiftData inheritance relationship”

I want to use the Observations AsyncSequence on some SwiftData @Model instances to determine if internal calculations need to be done. When a simple property is linked to the Observations it fires CONTINUOUSLY even though no change is made to the model property. Also, when I try to observe a property which is a list of another @Model type the Observations sequence does not fire when I add or remove items. I am hoping to use the async-algorithm's merge function so all the associated sequences can be combined since if any of the associated events should fire the calculation event.

I was wondering what the recommended way is to persist user settings with SwiftData? It seems the SwiftData API is focused around querying for multiple objects, but what if you just want one UserSettings object that is persisted across devices say for example to store the user's age or sorting preferences. Do we just create one object and then query for it or is there a better way of doing this? Right now I am just creating: import SwiftData @Model final class UserSettings { var age: Int = 0 var sortAtoZ: Bool = true init(age: Int = 0, sortAtoZ: Bool = true) { self.age = age self.sortAtoZ = sortAtoZ } } In my view I am doing as follows: import SwiftUI import SwiftData struct SettingsView: View { @Environment(.modelContext) var context @Query var settings: [UserSettings] var body: some View { ForEach(settings) { setting in let bSetting = Bindable(setting) Toggle(Sort A-Z, isOn: bSetting.sortAtoZ) TextField(Age, value: bSetting.age, format: .number) } .onAppear { if settings.

Hi all, I’m trying to understand SwiftData’s runtime semantics around optional to-many relationships, especially in the context of CloudKit-backed models. I ran into behavior that surprised me, and I’d like to confirm whether this is intended design or a potential issue / undocumented behavior. Minimal example import SwiftUI import SwiftData @Model class Node { var children: [Node]? = nil var parent: Node? = nil init(children: [Node]? = nil, parent: Node? = nil) { self.children = children self.parent = parent print(self.children == nil) } } struct ContentView: View { var body: some View { Button(Create) { _ = Node(children: nil) } } } Observed behavior If @Model is not used, children == nil prints true as expected. If @Model is used, children == nil prints false. Inspecting the macro expansion, it appears SwiftData initializes relationship storage using backing data placeholders and normalizes to-many relationships into empty collections at runtime, even w

Hello, I'm experiencing a significant delay getting the Family Controls entitlement approved for my Shield Configuration Extension, and I'm hoping someone here can help or has experienced something similar. Background: I'm developing an app that uses the Screen Time API with Family Controls. My main app bundle (lukedev.Bloka) was approved for Family Controls (Distribution) and works perfectly. The Problem My Shield Configuration Extension (lukedev.Bloka.Shield) has been stuck waiting for approval for over 2 weeks: Request ID: 6C8LD22UVM Submitted: November 20, 2025 Status: Still Submitted Current State: Only shows Family Controls (Development) in capabilities What I've Tried ✅ Submitted entitlement request via the proper channels ✅ Contacted Apple Developer Support (case #102762028251) ✅ Verified the main app has full Family Controls approval ✅ Deleted and regenerated all provisioning profiles multiple times ✅ Confirmed the App ID configuration is correct in the Developer Portal The Issue Without Family Contr

When I used to do Migrations, I always used ETL and then push to a dev system to review/test before going production. The migration support is SwiftData is fine for a little tweak. I might as well just just use new schema and context and write the custom code than use the SwiftData migration support.

I created a custom class that inherits from IOUserSCSIPeripheralDeviceType00 in the DriverKit SCSIPeripheralsDriverKit framework. When I attempted to send a vendor-specific command to a USB storage device using the UserSendCDB function of this class instance, the function returned the error: kIOReturnNotPrivileged (iokit_common_err(0x2c1)) // privilege violation However, when using UserSendCDB in the same way to issue standard SCSI commands such as INQUIRY or Test Unit Ready, no error occurred and the returned sense data was valid. Why is UserSendCDB able to send standard SCSI commands successfully, but vendor-specific commands return kIOReturnNotPrivileged? Is there any required entitlement, DriverKit capability, or implementation detail needed to allow vendor-specific CDBs? Below are the entitlements of my DriverKit extension: com.apple.developer.driverkit.transport.usb idVendor [number of vendorid] com.apple.developer.driverkit com.apple.developer.driverkit.allow-any-userclient-access com.a
