“SwiftData inheritance relationship”

To gain exclusive access to keyboard HID devices like Amazon Fire Bluetooth remote controls, my app has been installing a privileged helper tool with SMJobBless in the past. The app - which also has Accessibility permissions - then invoked and communicated with that helper tool through XPC. Now I'm looking into replacing that with a daemon installed through the newer SMAppService APIs, but running into a permission problem: If I try to exclusively open a keyboard HID device from the SMAppService-registered XPC service/daemon (which runs as root as seen in Activity Monitor), IOHIDDeviceOpen returns kIOReturnNotPermitted. I've spent many hours now trying to get it to work, but so far didn't find a solution. Could it be that XPC services registered as a daemon through SMAppService do not inherit the TCC permissions from the invoking process (here: Accessibility permissions) - and the exclusive IOHIDDeviceOpen therefore fails?

I'm working on a macOS app with a Safari web extension. I'm trying to share a SwiftData model between devices using CloudKit synchronization. I am able to get synchronization in the main app on the same device, CloudKit sync works correctly — changes appear in the CloudKit Dashboard under com.apple.coredata.cloudkit.zone. However, in the Safari App Extension, data is saved locally and persists across launches, but never syncs to CloudKit. I have followed the recommended practices for configuring the App Group and entitlements, but the issue persists. Questions: Is there an official limitation preventing Safari App Extensions from connecting to the CloudKit daemon (cloudd)? If not, what entitlements or configuration changes are required for a Safari App Extension to successfully sync with CloudKit? Is the xpc_error=159 from bootstrap_look_up() a known sandbox restriction for this extension type? Any guidance from Apple engineers or others who have successfully used CloudKit from a Safari App Extension

As a fun project, I'm wanting to model an electronic circuit. Components inherit from a superclass (ElectronicComponent). Each subclass (e.g. Resistor) has certain methods to return properties (e.g. resistance), but may vary by the number of outlets (leads) they have, and what they are named. Each outlet connects to a Junction. In my code to assemble a circuit, while I'm able to manually hook up the outlets to the junctions, I'd like to be able to use code similar to the following… class Lead: Hashable // implementation omitted { let id = UUID() unowned let component: ElectronicComponent weak var connection: Junction? init(component: ElectronicComponent, to connection: Junction? = nil) { self.component = component self.connection = connection } } @dynamicMemberLookup class ElectronicComponent { let id = UUID() var connections: Set = [] let label: String? init(label: String) { self.label = label } subscript(dynamicMember keyPath: KeyPath) -> T { self[keyPath: keyPath] } func connect(lead: KeyPath,

Hi , I'm struggling with visionOS window management and need help with closing child windows programmatically. App Structure My app has a Main-Sub window hierarchy: AWindow (Home/Main) BWindow (Main feature window) CWindow (Tool window - child of BWindow) Navigation flow: AWindow → BWindow (switch, 1 window on screen) BWindow → CWindow (opens child, 2 windows on screen) I want BWindow and CWindow to be separate movable windows (not sheet/popover) so users can position them independently in space. The Problem CWindow doesn't close when BWindow closes by tapping the X button below the app (next to the window bar) User clicks X on BWindow → BWindow closes but CWindow remains CWindow becomes orphaned on screen Can close CWindow programmatically when switching BWindow back to AWindow App launch issue After closing both windows, CWindow is remembered as last window Reopening app shows only CWindow instead of BWindow User gets stuck in CWindow with no way back to BWindow I've Tried Environment dismissWindow in clean

I am using SwiftData to model my data. For that i created a model called OrganizationData that contains various relationships to other entities. My data set is quite large and i am having a big performance issue when fetching all OrganizationData entities. I started debugging and looking at the sql debug log i noticed that when fetching my entities i run into faults for all relationships even when not accessing them. Fetching my entities: let fetchDescriptor = FetchDescriptor() let context = MapperContext(dataManager: self) let organizations = (try modelContainer.mainContext.fetch(fetchDescriptor)) Doing this fetch, also fetches all relationships. Each in a single query, for every OrganizationData entity. CoreData: annotation: to-many relationship fault relationship1 for objectID 0x8aa5249772916e00 fulfilled from database. Got 9 rows CoreData: annotation: to-many relationship fault relationship2 for objectID 0x8aa5249772916e00 fulfilled from database. Go
