Hi, My app hangs for about a second when I open the app when it's been in background phase. It doesn't hang every time, but it hangs randomly (like once in 10 times) when I open the app again. I am not able to reproduce what causes this hang. Hang Detection provides hang logs (spindump) when hang occurs. It has something to do with MusicKit as logs mention it but I cannot understand what it is. Please help me understand these logs. I am running iOS 17 beta 1 with MusicKit and ApplicationMusicPlayer.

We have a 7-year old codebase that uses a mix of frameworks including Rx and Firebase through Cocoapods. The compilation works fine up to XCode 14.2 but for some unknown reason the compilation just stuck / hang on XCode 14.3.x and XCode 15. There are several warnings in the codebase but the compiler does not output any error. Which is why we don't know what the exact issue(s) is/are. What's the change in XCode 14.3.x that could be causing this issue? If anyone has an idea on possible fix, willing to try it out.

I am trying to convert publicKeyFromDongleData to SecKey, then perform some tasks. After that, I want to convert SecKey to b64 String. I am assuming that publicKeyFromDongleData and b64 string will be the same. But, surprisingly, they are not the same. How can i resolve the issue? Is there any way around? My goal is to retain the public key before and after converting the same. let publicKeyFromDongleData = Data.init(base64Encoded: publicKeyFromDongle) guard let publicKeySecKey = SecKeyCreateWithData(publicKeyFromDongleData! as CFData, keyDict as CFDictionary, &amp;error) else { print("Failed to create public key:", error!.takeRetainedValue()) return nil } //var error:Unmanaged&lt;CFError&gt;? if let cfdata = SecKeyCopyExternalRepresentation(publicKeySecKey, &amp;error) { let data:Data = cfdata as Data let b64Key = data.base64EncodedString() print("after : \n") print(b64Key) }

Hi, I am trying to store user activities log in text file and once the session is over in another session the log will override the file automatically. Please any one help me to implement without using third party analytics library. Only using Apple class. Thank you.

Hi There, UISearchBar has its own "Cancel" button which can be shown/hidden with the property showsCancelButton. How to access it when writing UI test cases? (Or what is its accessibilityIdentifier). I want to do something like: enter some text in the search bar and then clear it with that button. Thanks in advance!

Certainly, here's an explanation and the minimal code to reproduce the issue in English: In SwiftUI, attempting to present a sheet or any other presentation view while a Menu view is open causes a conflict. This is because SwiftUI does not allow multiple presentation views to be open at the same time. Here's the simplest code to reproduce the issue: import SwiftUI struct ContentView: View { @State var showSheet = false var body: some View { VStack { Menu { Button("Option 1") { } Button("Option 2") { } } label: { Text("Open Menu") } Button(action: { showSheet = true }) { Text("Open Sheet") } .sheet(isPresented: $showSheet) { Text("Hello, Sheet!") } } } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() } }

I have multiple classes that are contained within one another. Initializing class A(no other classes as properties) has no issues, but the moment that it tries to initialize class B, which takes class A as a property, an EXC_BAD_ACCESS error is thrown while attempting to set the first property value. Class A: import Foundation import SwiftData @Model public class Service: Identifiable, Equatable, Codable { @Attribute(.unique) public var id: UUID public var title: String public var price: Int public var stripePriceId: String public var servicePhoto: String public var serviceLength: Int public var category: [String] init(id: UUID, title: String, price: Int, stripePriceId: String, servicePhoto: String, serviceLength: Int, category: Array<String>) { self.id = id self.title = title self.price = price self.stripePriceId = stripePriceId self.servicePhoto = servicePhoto self.serviceLength = serviceLength self.category = category } } Class B: import Foundation import SwiftData import SwiftUI @Model public class ServiceOrder: Identifiable, Codable, Equatable { public var id: UUID @Relationship(.noAction) public var service: Service public var quantity: Int = 1 public var subtotal: Int { return service.price * quantity } public init(id: UUID = UUID(), service: Service, quantity: Int) { self.id = id self.service = service self.quantity = quantity } public func getValue<T>(for key: KeyPath<ServiceOrder, T>) -> T { return self[keyPath: key] } // This is where the error is being thrown. The custom setValue and getValue methods were added to every class to mitigate an 'Ambiguous use of __Value()' error, but that's for another thread public func setValue<T>(for key: ReferenceWritableKeyPath<ServiceOrder, T>, to newValue: T) { self[keyPath: key] = newValue } // This was added to see if following the Builder pattern might mitigate the issue by ensuring that all properties were initialized before being passed in, it did not change anything class ServiceOrderBuilder { private var id: UUID? private var service: Service? private var quantity: Int? init() { } init(id: UUID = UUID(), service: Service, quantity: Int = 1) { self.id = id self.service = service self.quantity = quantity } func setId(id: UUID = UUID()) -> ServiceOrderBuilder { self.id = id return self } func setService(service: Service) -> ServiceOrderBuilder { self.service = service return self } func setQuantity(quantity: Int = 1) -> ServiceOrderBuilder { self.quantity = quantity return self } func build() -> ServiceOrder? { guard let id = id, let service = service, let quantity = quantity else { return nil } return ServiceOrder(id: id, service: service, quantity: quantity) } } Here's where I'm doing the initialization of everything. I'm trying to just create sample data. import SwiftData import Foundation @MainActor public let previewContainer: ModelContainer = { do { var container = try ModelContainer( for: [Event.self, Braider.self, Queue.self, QueueSlot.self, Cart.self, ServiceOrder.self], ModelConfiguration(inMemory: true) ) var context = container.mainContext var serviceSampleData: [Service] = [ Service( id: UUID(), title: "Event Braid", price: 20, stripePriceId: "", servicePhoto: "", serviceLength: 15, category: []), ..., ] serviceSampleData.forEach { service in context.insert(service) } // This is where the error is thrown, no issue initializing the above Services var serviceOrder1: ServiceOrder = ServiceOrder( service: serviceSampleData[0], quantity: 1) context.insert(serviceOrder1) // ...continue building higher classes/Models that utilize the lower ones return container } catch { print("Failed to create container") do { return try ModelContainer( for: [Event.self], ModelConfiguration(inMemory: true) ) } catch { fatalError() }} }() I assumed that this was a SwiftData issue, as I mentioned in response to this post but looking back this issue has been happening for 7+ years, so now I'm assuming I'm doing something incorrect.

I've had a little personal utility running for several versions of macOS that uses let client = CWWiFiClient.shared() if let ssid_name = client.interface()?.ssid() to get the current SSID name and prints it (along with a bunch of other active network details. With the most recent Sonoma Beta 2 and Xcode beta 2, this always returns nil. Doing the same thing in a playground works as expected. Is this a purposeful change or a bug I should file?

We are working on a new iOS application utilizing the new iOS 17 APIs, and I have updated Xcode to Xcode 15 Beta, and my iPhone 12 Pro to iOS 17 Beta 2, though this issue was also present on iOS 17 Beta 1. In Xcode, for "Signing and Capabilities" I have my Team set to my personal team, utilizing the "Automatically manage signing" tick. While the app will build and install on my phone, I immediately receive this error, with no popup to trust the developer. Going to Settings > General > VPN and Device Management, I can see my Development Team, and I am able to Trust my team. When trying to then Verify App(s), it tells me it will use my internet connection to verify the application. However, it will then do nothing, with no error, regardless of how many times I attempt to verify. Trying to open the app from my home screen will result in the repeated "Unable to Verify Error". Trying to reset network settings does not result in any change in this behavior, nor does a reset of the phone. I have tried 4 different high quality WiFi networks, as well as a fully connection AT&T cellular LTE connection, and still receive this error. I am running out of diagnostic scenarios, and I'm curious if anyone has found a resolution to this?

@Environment can't use for Binding? @Observable final class View1Model { var text: String = "" } struct View1: View { @State var viewModel = View1Model() var body: some View { View2() .environment(viewModel) } } struct View2: View { @Environment(View1Model.self) var viewModel var body: some View { TextField("Text", text: $viewModel.text) // Cannot find '$viewModel' in scope } }

I get the following error when I try to add the modelContainer to the Window SwiftData/DataStoreCoreData.swift:119: Fatal error: Unable to determine Bundle Name

I got the error "[API] Failed to create 0x88 image slot (alpha=1 wide=0) (client=0xfbe80e61) [0x5 (os/kern) failure]" when using NavigationStack of SwiftUI for navigation. It only happen in iPadOS (16.4) but not iOS in iPhone. Below is the view I am using. struct NewView: View { var body: some View { NavigationStack { VStack { NavigationLink("Show Detail View") { DetailView() } } .navigationTitle("Navigation") } } } struct DetailView: View { var body: some View { Text("This is the detail view") } } Anyone know the reason?

Hi all, I have tried everything (that i'm aware of) but i cannot seem to get around this error. My app is setup using only SwiftData and is basically a custom version of the apps shown in SwiftData docs. I have done the following to try to debug: Deleted app from device Clean and re-build Delete derived data and rebuild I have tried reverting changes made to the @Models i have define Every combination of the above steps + rebuilding Im at a loss. No clue how to resolve this. Some weird observations. This error only occurs after the first context.insert call. The first is successful and data is properly persisted across app launches. All subsequent attempts to insert result in the following error: Error Domain=NSCocoaErrorDomain Code=134020 "The model configuration used to open the store is incompatible with the one that was used to create the store."

I'm working through Apple's Mac Catalyst tutorial but it seems to be riddled with bugs and coding issues, even in the final part of the completed app which I dowmloaded and ran. I don't see these problems on IPad simulator. I don't know if it's because Catalyst has problems itself or there's something else going on that I can fix myself. Any insight into these errors would be very much appreciated! PS: The app seems to run ok on Mac without crashing despite the muliple issues

Just a quick observation. I find that the NSNotification.Name NEVPNStatusDidChange is not visible when the Swift Compiler setting: C++ and Objective-C Interoperability is set to C++/Objective-C++. Simply switching between C/Objective-C and C++/Objective-C++, a successfully building app is no longer able to build with error: Type 'NSNotification.Name?' has no member 'NEVPNStatusDidChange'. The Swift code being used is: NotificationCenter.default.addObserver(self, selector: #selector(self.updateNetworkStatus(_:)), name: .NEVPNStatusDidChange, object: nil)

I'm trying to query HealthKit for all of users medications, including prescribed medications and user-entered medications. Using a HKSampleQuery with type HKClinicalTypeIdentifierMedicationRecord, I'm able to fetch medications that have been prescribed by a healthcare provider (eg medications associated with clinical FHIR records): let type = HKClinicalType(.medicationRecord) let predicate = HKQuery.predicateForClinicalRecords(withFHIRResourceType: .medicationStatement) let query = HKSampleQuery(sampleType: type, predicate: predicate, limit: kRecordLimit, sortDescriptors: nil) { q, samples, error in // this returns only -clinical- records // it doesnt include manually entered meds } However, medications which I have manually entered into the Health app with a user-defined schedule and dosing do NOT appear in the results of this query. is it possible to fetch medications which have been manually entered by the user?

I am working through the Getting Started with App Development and on Page 142 it has you write in the updateUI() function if else statement lightButton.setTitle("Off", for: .normal) and lightButton.setTitle("On", for: .normal). My app crashes every time after building it and running it. Image reference below. The app works perfectly fine before adding these two statements. import UIKit class ViewController: UIViewController { @IBOutlet var lightButton: UIButton! var lightOn = true fileprivate func updateUI() { if lightOn { view.backgroundColor = .white lightButton.setTitle("Off", for: .normal) } else { view.backgroundColor = .black lightButton.setTitle("On", for: .normal) } } @IBAction func buttonPressed(_ sender: Any) { lightOn.toggle() updateUI() } override func viewDidLoad() { super.viewDidLoad() updateUI() // Do any additional setup after loading the view. } } Getting this error at the end. libc++abi: terminating due to uncaught exception of type NSException (lldb)

The loop plays smoothly in audacity but when I run it in the device or simulator it clicks each loop at different intensities. I config the session at App level: let audioSession = AVAudioSession.sharedInstance() do { try audioSession.setCategory(.playback, mode: .default, options: [.mixWithOthers]) try audioSession.setActive(true) } catch { print("Setting category session for AVAudioSession Failed") } And then I made my method on my class: func playSound(soundId: Int) { let sound = ModelData.shared.sounds[soundId] if let bundle = Bundle.main.path(forResource: sound.filename, ofType: "flac") { let backgroundMusic = NSURL(fileURLWithPath: bundle) do { audioPlayer = try AVAudioPlayer(contentsOf:backgroundMusic as URL) audioPlayer?.prepareToPlay() audioPlayer?.numberOfLoops = -1 // for infinite times audioPlayer?.play() isPlayingSounds = true } catch { print(error) } } } Does anyone have any clue? Thanks! PS: If I use AVQueuePlayer and repeat the item the click noise disappear (but its no use, because I would need to repeat it indefinitely without wasting memory), if I use AVLooper I get a silence between loops. All with the same sound. Idk :/ PS2: The same happens with ALAC files.
