I have received permission from Apple to access SensorKit data for my app. I have granted all necessary permissions, but no data is being retrieved. The didCompleteFetch method is being called, but I’m unsure where to find event data like Device Usage and Ambient Light. Additionally, the didFetchResult method is never called. Could anyone please assist me in resolving this issue? Any guidance or troubleshooting steps would be greatly appreciated. import SensorKit class ViewController: UIViewController, SRSensorReaderDelegate { let store = SRSensorReader(sensor: .deviceUsageReport) override func viewDidLoad() { super.viewDidLoad() requestSensorAuthorization() } func requestSensorAuthorization() { var sensors: Set<SRSensor> = [ .accelerometer, .deviceUsageReport, .messagesUsageReport, .visits, .keyboardMetrics, .phoneUsageReport, .ambientLightSensor ] if #available(iOS 16.4, *) { sensors.insert(.mediaEvents) } SRSensorReader.requestAuthorization(sensors: sensors) { error in if let error = error { print("Authorization failed: \(error.localizedDescription)") } else { self.store.startRecording() self.requestSensorData() print("Authorization granted for requested sensors.") } } } func requestSensorData() { let fromTime = SRAbsoluteTime.fromCFAbsoluteTime(_cf: Date().addingTimeInterval(-60 * 60).timeIntervalSinceReferenceDate) let toTime = SRAbsoluteTime.fromCFAbsoluteTime(_cf: Date().timeIntervalSinceReferenceDate) let request = SRFetchRequest() request.from = fromTime request.to = toTime request.device = SRDevice.current store.fetch(request) store.delegate = self } func sensorReader(_ reader: SRSensorReader, didCompleteFetch fetchRequest: SRFetchRequest) { print("Fetch request completed: \(fetchRequest.from) to \(fetchRequest.to)") Task { do { let samples = try await reader.fetch(fetchRequest) print("Samples count: \(samples)") } catch { print("Error Fetching Data: \(error.localizedDescription)") } } } func sensorReader(_ reader: SRSensorReader, fetching fetchRequest: SRFetchRequest, didFetchResult result: SRFetchResult<AnyObject>) -> Bool { print(result) return true } }

Dear all, Sorry if the topic has already been commented but I could not be able to find it in over 10,000 picks using the forum search field... My problem is that with any NSTextField in my app, a click will result in a memory leak. There is no code attached, just bindings to NSNumber properties. How can I fix this ? Thanks for your help. Best regards Chris

Hi everyone, we’d appreciate your input on the following use case – thanks in advance! In our iPhone and Apple Watch app, we’re using the NearbyInteraction API to measure the distance between both devices via UWB. Setup: On the iPhone, we start a LiveActivity together with the NISession, to keep the ranging active in the background. ✅ Good news: On iOS 18.4, this works as expected – the NISession stays active in the background as long as the Live Activity is running. Current issues: As soon as the Watch app moves to the background, ranging seems to pause and is eventually terminated. → Question 1: Is there a way to keep the NISession active on the Watch when the app goes into the background? Audio playback from background not working: We'd like to trigger audio playback when certain distance changes are detected. So far, we can only trigger haptic feedback in the background – audio does not play. → Question 2: Is it possible to play audio (e.g. using AVAudioPlayer) while a NISession and a LiveActivity are running in the background? We’d be grateful for any advice or best practices for this combination. Thanks and best regards!

I noticed that sometimes TextKit2 decides to crop some text instead of soft-wrapping it to the next line. This can be reproduced by running the code below, then resizing the window by dragging the right margin to the right until you see the text with green background (starting with “file0”) at the end of the first line. If you now slowly move the window margin back to the left, you’ll see that for some time that green “file0” text is cropped and so is the end of the text with red background, until at some point it is soft-wrapped on the second line. I just created FB18289242. Is there a workaround? class ViewController: NSViewController { override func loadView() { let textView = NSTextView(frame: CGRect(x: 0, y: 0, width: 400, height: 400)) let string = NSMutableAttributedString(string: "file0\t143548282\t1970-01-01T00:00:00Z\t1\t1f40fc92da241694750979ee6cf582f2d5d7d28e18335de05abc54d0560e0f5302860c652bf08d560252aa5e74210546f369fbbbce8c12cfc7957b2652fe9a75", attributes: [.foregroundColor: NSColor.labelColor, .backgroundColor: NSColor.red.withAlphaComponent(0.2)]) string.append(NSAttributedString(string: "file0\t143548290\t1970-01-01T00:05:00Z\t 2\t0f6460d0ed7825fed6bda0f4d9c14942d88edc7ff236479212e69f081815e6f1742c272753b77cc6437f06ef93a46271c6ff9513c68945075212434080e60c82", attributes: [.foregroundColor: NSColor.labelColor, .backgroundColor: NSColor.green.withAlphaComponent(0.2)])) textView.textContentStorage!.textStorage!.setAttributedString(string) textView.autoresizingMask = [.width, .height] let scrollView = NSScrollView(frame: CGRect(x: 0, y: 0, width: 400, height: 400)) scrollView.documentView = textView scrollView.hasVerticalScroller = true scrollView.translatesAutoresizingMaskIntoConstraints = false view = scrollView } }

I used the Multipeer Connectivity Framework to allow players of my game app to see the highest score along with their own score as the game progresses. It works fine running in 3 or 4 simulators in Xcode. However, I was just told by two Apple support reps that bluetooth connectivity is not allowed between two Apple devices, other than for watches, AirPods, headphones, etc. My question is: can two iPhones or iPads connect for peer-to-peer play? Can they play offline? If the answer is yes to either or both of those questions, how do I get that to happen since I get an error message when trying to connect two iPhones via bluetooth even though they can see each other in the Other Devices list? If the answer is no, then why does Apple provide a Multipeer Connectivity Framework and simulate that type of device to device connection with the Xcode simulators?

I'm currently integrating SwiftUI into an AppKit based application and was curious if the design pattern below was viable or not. In order to "bridge" between AppKit and SwiftUI, most of my SwiftUI "root" views have aViewModel that is accessible to the SwiftUI view via @ObservedObject. When a SwiftUI views need to use NSViewRepresentable I'm finding the use of a ViewModel and a Coordinator to be an unnecessary layer of indirection. In cases where it makes sense, I've just used the ViewModel as the Coordinator and it all appears to be working ok, but I'm curious if this is reasonable design pattern or if I'm overlooking something. Consider the following pseudo code: // 1. A normal @ObservedObject acting as the ViewModel that also owns and manages an NSTableView. @MainActor final class ViewModel: ObservedObject, NSTableView... { let scrollView: NSScrollView let tableView: NSTableView @Published var selectedTitle: String init() { // ViewModel manages tableView as its dataSource and delegate. tableView.dataSource = self tableView.delegate = self } func reload() { tableView.reloadData() } // Update view model properties. // Simpler than passing back up through a Coordinator. func tableViewSelectionDidChange(_ notification: Notification) { selectedTitle = tableView.selectedItem.title } } // 2. A normal SwiftUI view, mostly driven by the ViewModel. struct ContentView: View { @ObservedObject model: ViewModel var body: some View { Text(model.selectedTitle) // No need to pass anything down other than the view model. MyTableView(model: model) Button("Reload") { model.reload() } Button("Delete") { model.deleteRow(...) } } } // 3. A barebones NSViewRepresentable that just vends the required NSView. No other state is required as the ViewModel handles all interactions with the view. struct MyTableView: NSViewRepresentable { // Can this even be an NSView? let model: ViewModel func makeNSView(context: Context) -> some NSView { return model.scrollView } func updateNSView(_ nsView: NSViewType, context: Context) { // Not needed, all updates are driven through the ViewModel. } } From what I can tell, the above is working as expected, but I'm curious if there are some situations where this could "break", particularly around the lifecycle of NSViewRepresentable Would love to know if overall pattern is "ok" from a SwiftUI perspective.

I have a simple Picker where the options available change by the view state. I would like to have the transition animated but the default animation is not good so I tried setting a .transition() and or an .animation() inside an item on the picker but it is ignored. The same happens if the transition is set on the picker itself since it's always present. Am I doing it right and is just not posible or is there something else to do? Code to reproduce the issue: struct ContentView: View { @State var list: [String] = [ "Item 4", "Item 5", "Item 6", "Item 7", "Item 8", ] @State var selected: String? @State var toggle: Bool = false var body: some View { VStack { Picker("List", selection: $selected) { ForEach(list, id: \.self) { Text($0).tag($0) // .transition(.opacity) } } .pickerStyle(.segmented) // .transition(.opacity) HStack { Button(action: swapOptions) { Text("Swap") } } } .padding() } } extension ContentView { func swapOptions() { withAnimation { toggle.toggle() switch toggle { case true: list = [ "Item 1", "Item 2", "Item 3", "Item 4", "Item 5", ] case false: list = [ "Item 4", "Item 5", "Item 6", "Item 7", "Item 8", ] } } } } ``

I have setup the extension for replaykit successfully , the bundle id and everything is correct but still the system broadcast picker view is not showing my own app to broadcast screen content when trying to do system wide broadcast.

Hi, A class initialized as the initial value of an @State property is not released until the whole View disappears. Every subsequent instance deinitializes properly. Am I missing something, or is this a known issue? struct ContentView: View { // 1 - init first SimpleClass instance @State var simpleClass: SimpleClass? = SimpleClass(name: "First") var body: some View { VStack { Text("Hello, world!") } .task { try? await Task.sleep(for: .seconds(2)) // 2 - init second SimpleClass instance and set as new @State // "First" should deinit simpleClass = SimpleClass(name: "Second") // 3 - "Second" deinit just fine simpleClass = nil } } } class SimpleClass { let name: String init(name: String) { print("init: \(name)") self.name = name } deinit { print("deinit: \(name)") } } output: init: First init: Second deinit: Second Thanks

iOS 18.4.1 When I change a Google type event to an iCloud type, a "Cannot Save Event" prompt box pops up. We have also received user feedback that recurring events also fail to save. After updating to iOS 18.4 when trying to save changes to an existing repeating event, the message "Cannot Save Event" will appear. EventKitUI

I've got a UIKit app that displays a lot of text, and we've completely turned off the system text selection menu and we show our own custom thing instead, to increase discoverability of our text selection actions. But now that iOS 26 can show the full menu even on iPhone, we're looking at switching back to the system menu. It still shows a smaller horizontal-layout menu at first, and then you tap the > symbol to expand to the full menu. Is it possible to jump straight to the full menu, and skip the smaller horizontal one entirely?

My setup: a UILabel with text in it and then let aBugRenderer = UIGraphicsImageRenderer(size: aBugLabel.bounds.size) let aBugImage = aBugRenderer.image { context in aBugLabel.drawHierarchy(in: aBugLabel.bounds, afterScreenUpdates: true) } The layout and everything is correct, the image is correct, but I used my colors in the displayP3 color space to configure the source UILabel.textColor And unfortunately, the resulted image ends up being sRGB IEC61966-2.1 color space and the color appears way bleaker than when it's drawn natively. Question: how can I set up the renderer so that it draws the same color.

Goal : Drag a sphere across the room and track it's position Problem: The gesture seems to have no effect on the sphere ModelEntity.

I have a DocumentGroup working with a FileDocument, and that's fine. However, when someone creates a new document I want them to have to immediately save it. This is the behavior on ipadOS and iOS from what I can understand (you select where before the file is created). There seems to be no way to do this on macOS? I basically want to have someone: create a new document enter some basic data hit "create" which saves the file then lets the user start editing it (1), (2), and (4) are done and fairly trivial. (3) seems impossible, though...? This really only needs to support macOS but any pointers would be appreciated.

Hi Apple team and community, We’re encountering a strange issue with Live Activity that seems related to memory management or background lifecycle. ❓ Issue: Our app updates a Live Activity regularly (every 3 minutes) using .update(...). However, after the app remains in the background for around 8 hours, the Live Activity reverts to the initial state that was passed into .request(...). Even though the app continues sending updates in the background, the UI on the Lock Screen and Dynamic Island resets to the original state.

How should I program the globe key? If possible, could you teach me in C language?

I want SensorKit data for research purposes in my current application. I have applied for and received permission from Apple to access SensorKit data. During implementation, I encountered an issue in which no data was being retrieved despite granting all the necessary permissions. I am using did CompleteFetch & didFetchResult delegate methods for retrieving data from Sensorkit. CompleteFetch method calls but where I can find different event data like Device usage, Ambient Light, etc? & didFetchResult method does not call. Methods I am using: 1. func sensorReader(_ reader: SRSensorReader, didCompleteFetch fetchRequest: SRFetchRequest) 2. func sensorReader(_ reader: SRSensorReader, fetching fetchRequest: SRFetchRequest, didFetchResult result: SRFetchResult<AnyObject>) -> Bool Could anyone please assist me in resolving this issue? Any guidance or troubleshooting steps would be greatly appreciated.
