Hello, I've been working on my macos app for months, today I opened XCode, and it's full of the same errors "Value of type 'URL' has no member 'url''" and "Cannot convert value of type 'Binding' to expected argument type 'CGFloat'". I didn't change ANYTHING, I didn't update nor remove anything, the 3rd party module I'm using didn't get updated, this is all out of the blue! I tried to clean the build folder, erase the derivated data, rebuild a new project, these errors won't go away...worst part is that another of my app use the same codes and there I see the errors but the app still compiles and build!!

[Submitted as FB14860454, but posting here since I rarely get responses in Feedback Assistant] In a simple SwiftData app that adds items to a list, memory usage drastically increases as items are added. After a few hundred items, the UI lags and becomes unusable. In comparison, a similar app built with CoreData shows only a slight memory increase in the same scenario and does NOT lag, even past 1,000 items. In the SwiftData version, as each batch is added, memory spikes the same amount…or even increases! In the CoreData version, the increase with each batch gets smaller and smaller, so the memory curve levels off. My Question Are there any ways to improve the performance of adding items in SwiftData, or is it just not ready for prime time? Example Projects Here are the test projects on GitHub if you want to check it out yourself: PerfSwiftData PerfCoreData

Hello, I have a problem with the .onMove function. I believe I have set everything up properly. However, the moving does not seem to be working correctly. When I try to move the item, it is highlighted first, as it is supposed to be. Then, while I am moving it through the list, it disappears for some reason, and at the end of the move, it comes back to its initial place. (I use iOS 16.0 minimum, so I don't have to include the EditButton(). It works the same in the edit mode tho) import SwiftUI struct Animal: Identifiable { var id = UUID() var name: String } struct ListMove: View { @State var animals = [Animal(name: "Dog"), Animal(name: "Cat"), Animal(name: "Cow"), Animal(name: "Goat"), Animal(name: "Chicken")] var body: some View { List { ForEach(animals) { animal in Text(animal.name) } .onMove(perform: move) } } func move(from source: IndexSet, to destination: Int) { animals.move(fromOffsets: source, toOffset: destination) } } #Preview { ListMove() }

I found that my visionOS Simulator is very strange. Many functions and features are missing. For example, I learned from the Internet that the immersive scenes of Environments in their visionOS Simulator can be opened, but I click There was no response after the attack. There are not only these, but also many system features. I saw on the Internet that other developers have them, and I am missing. I'm worried that this will have an impact on me when testing my app. May I ask why? Some information: My updated Xcode version is the latest Xcode15.1Beta. Device: iMac (2021) Simulator system number: 21N305

I've got a problem with compatibility with Swift6 in iOS app that I have no idea how to sort it out. That is an extract from my main app file @MainActor @main struct LangpadApp: App { ... @State private var notificationDataProvider = NotificationDataProvider() @UIApplicationDelegateAdaptor(NotificationServiceDelegate.self) var notificationServiceDelegate var body: some Scene { WindowGroup { TabView(selection: $tabSelection) { ... } .onChange(of: notificationDataProvider.dateId) { oldValue, newValue in if !notificationDataProvider.dateId.isEmpty { tabSelection = 4 } } } } init() { notificationServiceDelegate.notificationDataProvider = notificationDataProvider } } and the following code shows other classes @MainActor final class NotificationServiceDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate { var notificationDataProvider: NotificationDataProvider? func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool { UNUserNotificationCenter.current().delegate = self return true } func setDateId(dateId: String) { if let notificationDataProvider = notificationDataProvider { notificationDataProvider.dateId = dateId } } nonisolated func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse) async { // After user pressed notification let content = response.notification.request.content if let dateId = content.userInfo["dateId"] as? String { await MainActor.run { setDateId(dateId: dateId) } } } nonisolated func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification) async -> UNNotificationPresentationOptions { // Before notification is to be shown return [.sound, .badge, .banner, .list] } } @Observable final public class NotificationDataProvider : Sendable { public var dateId = "" } I have set Strict Concurrency Checking to 'Complete.' The issue I'm facing is related to the delegate class method, which is invoked after the user presses the notification. Current state causes crash after pressing notification. If I remove "nonisolated" keyword it works fine but I get the following warning Non-sendable type 'UNNotificationResponse' in parameter of the protocol requirement satisfied by main actor-isolated instance method 'userNotificationCenter(_:didReceive:)' cannot cross actor boundary; this is an error in the Swift 6 language mode I have no idea how to make it Swift6 compatible. Does anyone have any clues?

Hi, As AppStorage does not support arrays, I found an extension online that allows for handling arrays of strings with AppStorage. However, in my use case, I need to handle arrays of boolean values. Below is the code. Any help would be greatly appreciated. extension Array: RawRepresentable where Element: Codable { public init?(rawValue: String) { guard let data = rawValue.data(using: .utf8), let result = try? JSONDecoder().decode([Element].self, from: data) else { return nil } self = result } public var rawValue: String { guard let data = try? JSONEncoder().encode(self), let result = String(data: data, encoding: .utf8) else { return "[]" } return result } }

Getting this error several times when presenting a modal window over my splitview window when running it on my Mac using Swift/Mac Catalyst in XCode 14.2.

(The "bleep" was a debugging print code I put in the unwind segue). 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

I implemented Sign in with Apple but in all cases the button is always black. I would like to show it in light/ dark mode depending on the phone settings. This is my code: class MyAuthorizationAppleIDButton: UIButton { private var authorizationButton: ASAuthorizationAppleIDButton! @IBInspectable var cornerRadius: CGFloat = 3.0 @IBInspectable var authButtonType: Int = ASAuthorizationAppleIDButton.ButtonType.default.rawValue @IBInspectable var authButtonStyle: Int = ASAuthorizationAppleIDButton.Style.black.rawValue override public init(frame: CGRect) { super.init(frame: frame) } required public init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) } override public func draw(_ rect: CGRect) { super.draw(rect) // Create ASAuthorizationAppleIDButton authorizationButton = ASAuthorizationAppleIDButton(authorizationButtonType: .signIn, authorizationButtonStyle: .black) let type = ASAuthorizationAppleIDButton.ButtonType.init(rawValue: authButtonType) ?? .default let style = ASAuthorizationAppleIDButton.Style.init(rawValue: authButtonStyle) ?? .black authorizationButton = ASAuthorizationAppleIDButton(authorizationButtonType: type, authorizationButtonStyle: style) authorizationButton.cornerRadius = cornerRadius // Show authorizationButton addSubview(authorizationButton) // Use auto layout to make authorizationButton follow the MyAuthorizationAppleIDButton's dimension authorizationButton.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ authorizationButton.topAnchor.constraint(equalTo: self.topAnchor, constant: 0.0), authorizationButton.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 0.0), authorizationButton.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: 0.0), authorizationButton.bottomAnchor.constraint(equalTo: self.bottomAnchor, constant: 0.0), ]) } } So basically with the code above, I can set on Storyboard the style of the button but it seems that even if I change the value at my code, the result is based on what I chose on Storyboard's variable. Is there any solution where I would be able to show the button in light/ dark mode depending on the phone settings ?

Bug When you try to extend from NSViewRepresentable but you have a class named Context swift throws a error message that doesn't help at all.

I have created my own SPM through File -> New -> Package Package.swift looks like: // swift-tools-version: 5.10 // The swift-tools-version declares the minimum version of Swift required to build this package. import PackageDescription let package = Package( name: "MyPackage", platforms: [.iOS(.v16), .macCatalyst(.v16), .macOS(.v14)], products: [.library(name: "MyPackage", targets: ["MyPackage"]),], dependencies: [ .package(path: "../external-package") ], targets: [ .target(name: "MyPackage", path: "Sources"), .testTarget(name: "MyPackageTests", dependencies: ["MyPackage"]), ] ) When I run swift build the error says: '.../MyPackage/.build/arm64-apple-macosx/debug/external-package.build/external-package-Swift.h' not found and surely, when I go to directory: .../MyPackage/.build/arm64-apple-macosx/debug/external-package.build/ there are only 2 files in there: module.modulemap & output-file-map.json All source files from external-package are missing, therefore swift build fails. The only solution I've found is to copy external-package.build folder manually into: '.../MyPackage/.build/arm64-apple-macosx/debug/` What am I missing here? Should swift build create those files in there, or they should be resolved somehow differently? Note: external-package is not in any way unique, this happens to any added dependency I'm running on macOS 14.6.1 on Apple Silicon M1 Pro with Xcode 15.4

Hey everyone, I'm working on implementing an AppLimit, where after accumulating x minutes of Screen Time for an app, it should be blocked. It works fine on the first day, but stops functioning correctly on subsequent days. What I'm Doing I start a 24/7 schedule with a DeviceActivityEvent that has a specified Screen Time threshold. In my DeviceActivityMonitor, I'm reacting to the eventDidReachThreshold. Once the accumulated time is reached, the app is blocked. This works as expected on the first day. Issues I'm Experiencing / Questions Second Day Issue: On the second day, the app is no longer blocked after the Screen Time threshold is reached, even though it worked on the first day. This leads me to suspect that a DeviceActivityEvent is "consumable". Is this correct? Pre-existing Screen Time Issue: If a user has already surpassed the Screen Time threshold before monitoring starts, the app isn't blocked once the schedule is set up. This leads to 2 issues: I would expect that the accumulated amount of time after starting the schedule would result in the call of eventDidReachThreshold. But it is never called It could also be the case that the previously accumulated time is being kept in mind, but that would mean the apps should be blocked, which isn't the case. Does the threshold account for accumulated Screen Time before the schedule begins? I haven't tested setting a limit of 10 minutes, accumulating 3 minutes of Screen Time, then starting the schedule and accumulating the remaining time, but I'm curious if anyone has encountered this behavior. Does anyone have an explanation for this behavior? Any help would be greatly appreciated!

Dear, We are working on a solution that uses MDM to manage devices and create features for our users. As part of this, we want to implement a feature that retrieves the device's location even when the app is closed (killed). Is there a way to achieve this? Since we are an MDM solution, is there a function available within MDM that allows us to obtain this information? We are considering implementing the Location Push Service Extension. If we do, will we be able to receive latitude and longitude even if the app is closed?

Hi, For HTTP requests, I have the following function: func createAccount(account: Account, completion: @escaping (Response) -> Void) { guard let url = URL(string: "http://localhost:4300/account") else { return } var request = URLRequest(url: url) request.httpMethod = "POST" request.setValue("application/json", forHTTPHeaderField: "Content-Type") guard let encoded = try? JSONEncoder().encode(account) else { print("Failed to encode request") return } request.httpBody = encoded URLSession.shared.dataTask(with: request) { (data, response, error) in guard let data = data else { return } do { let resData = try JSONDecoder().decode(Response, from: data) DispatchQueue.main.async { completion(resData) } } catch let jsonError as NSError { print("JSON decode failed: \(jsonError)") } }.resume() } Because various HTTP requests use different body structs and response structs, I have a HTTP request function for each individual HTTP request. How can I condense this into one function, where the passed struct and return struct are varying, so I can perhaps pass the struct types in addition to the data to the function? Any guidance would be greatly appreciated.

I noticed that running my app in Xcode 16 crashes often. It seems this is due to the strictness Swift 6 adds at runtime. Even after making sure the Swift Language Mode is 5 for the main target and all modules. I'm migrating to Swift 6 but I probably won't be done before iOS 18 drops so my question is. Can I still ship the app supporting iOS 18 using Xcode 15.4 and Swift 5.10?

I want to implement a stack that works quite like a circular buffer. void** pp = malloc(sizeof(id) * 100); pp[index] = someObject; // later on somewhere: MyObject* myObj = (MyObject*)pp[index]; Is this correct? Does this approach work with ARC?

There are some reliable and affordable Polar H10 ECG reader apps available on the App Store: I’ve been using one for a couple of years. However, I recently needed to incorporate an ECG capability into an app that already uses the Polar H10 for RR Interval monitoring, but the documentation online for Polar ECG is scarce and sometimes incorrect. Polar provides an SDK, but this covers many different devices and so is quite complex. Also, it’s based on RxSwift - which I prefer not to use given that my existing app uses native Swift async and concurrency approaches. I therefore offer this description of my solution in the hope that it helps someone, somewhere, sometime. The Polar H10 transmits ECG data via Bluetooth LE as a stream of frames. Each frame is length 229 bytes, with a 10 byte leader and then 73 ECG data points of 3 bytes each (microvolts as little-endian integer, two’s complement negatives). The leader’s byte 0 is 0x00, bytes 1 - 8 are a timestamp (unknown epoch) and byte 9 is 0x00. The H10’s sampling rate is 130Hz (my 2 devices are a tiny fraction higher), which means that each frame is transmitted approximately every half second (73/130). However, given the latencies of bluetooth transmission and the app’s processing, any application of a timestamp to each data point should be based on a fixed time interval between each data point, i.e. milliseconds interval = 1000 / actual sampling rate. From my testing, the time interval between successive frame timestamps is constant and so the actual sampling interval is that interval divided by 73 (the number of samples per frame). I’ve noticed, with both the 3rd party app and my own coding, that for about a second (sometimes more) the reported voltages are very high or low before settling to “normal” oscillation around the isoelectric line. This is especially true when the sensor electrode strap has only just been placed on the chest. To help overcome this, I use the Heart Rate service UUID “180D” and set notify on characteristic "2A37" to get the heart rate and RR interval data, of which the first byte contains flags including a sensor contact flag (2 bits - both set when sensor contact is OK, upon which I setNotifyValue on the ECG data characteristic to start frame delivery). Having discovered your Polar H10, connected to it and discovered its services you need to discover the PMD Control Characteristic within the PMD Service then use it to request Streaming and to request the ECG stream (there are other streams). Once the requests have been accepted (didWriteValueFor Characteristic) then you start the Stream. Thereafter, frames are delivered by the delegate callback func peripheral(_ peripheral: CBPeripheral, didUpdateValueFor characteristic: CBCharacteristic, error: Error?) for the characteristic.uuid == pmdDataUUID The following code snippets, the key aspects of the solution, assume a working knowledge of CoreBluetooth. Also, decoding of data (code not provided) requires a knowledge of byte and bit-wise operations in Swift (or Objective-C). // CBUUIDs and command data let pmdServiceUUID = CBUUID.init( string:"FB005C80-02E7-F387-1CAD-8ACD2D8DF0C8" ) let pmdControlUUID = CBUUID.init( string:"FB005C81-02E7-F387-1CAD-8ACD2D8DF0C8" ) let pmdDataUUID = CBUUID.init( string:"FB005C82-02E7-F387-1CAD-8ACD2D8DF0C8" ) let reqStream = Data([0x01,0x02]) let reqECG = Data([0x01,0x00]) let startStream = Data([0x02, 0x00, 0x00, 0x01, 0x82, 0x00, 0x01, 0x01, 0x0E, 0x00]) // Request streaming of ECG data func peripheral(_ peripheral: CBPeripheral, didDiscoverCharacteristicsFor service: CBService, error: Error?) if service.uuid == pmdServiceUUID { for pmdChar in service.characteristics! { if pmdChar.uuid == pmdControlUUID { peripheral.setNotifyValue(true, for: pmdChar) peripheral.writeValue(reqStream, for: pmdChar, type: .withResponse) peripheral.writeValue(reqECG, for: pmdChar, type: .withResponse) } } } } // Request delivery of ECG frames - actual delivery subject to setNotify value func peripheral(_ peripheral: CBPeripheral, didWriteValueFor characteristic: CBCharacteristic, error: Error?) { // this responds to the reqStream and reqECG write values if error != nil { print("**** write error") return } if ecgStreamStarted { return } // I use a flag to prevent extraneous stream start commands guard let charVal = characteristic.value else { return } if charVal[0] == 0xF0 && charVal[1] == 0x01 { peripheral.writeValue(startStream, for: characteristic, type: .withResponse) ecgStreamStarted = true } } For “live” charting, I create an array of data points, appending each frame’s set on arrival, then provide those points to a SwiftUI View with a TimeLineView(.periodic(from: .now, by:actual sampling interval)) and using Path .addlines with the Y value scaled appropriately using GeometryReader. So far, I’ve found no way of cancelling such a TimeLineView period, so any suggestions are welcome on that one. An alternative approach is to refresh a SwiftUI Chart View on receipt and decoding of each frame, but this creates a stuttered appearance due to the approximately half-second interval between frames.

I've been relishing Develop in Swift: Fundamentals as an introduction to Swift. It's wonderful! Having limited time, and ultimately targeting visionOS development, I've reached a point where any UIKit content feels like a distraction from my goals. Hence I'm switching to SwiftUI Bootcamp by Swiftful Thinking on YouTube, SwiftUI Concepts Tutorials, and SwiftUI Tutorials by Apple. Is there any official word on updates to the Develop in Swift series? Failing that, any other recommendations on how to bridge between Fundamentals and visionOS development?
