Does SwiftUI now support the ability for a chart to have two different Y Axes? ChaptGPT seems to think it does, but I keep getting compiler errors in XCode.

I recently encountered an issue with Xcode 16.2 while attempting to integrate Settings.bundle into a new app. I added Settings.bundle as a new file (using the provided template), but when I ran the app (the standard simple "Hello World" project), the expected three default controls (Name, Enabled, Slider) did not appear in the app's settings. To troubleshoot, I downgraded my system to macOS Sonoma 14.7.2 and Xcode 15.4 (on a 2023 Mac Mini, M2). After this downgrade, everything worked as expected. With a new project, adding Settings.bundle, and running the app, the settings entry for the app appeared, including the three default fields. This behavior suggests a potential issue or incompatibility with Xcode 16.2.

We want to do below addition to iOS Mobile App. Airpod announces Push notification = which is workking now we want to use voice command that "Reply to this" and sending Reply to that notification but it is saying it is not supported in your app. So basically we need to use feature - Listen and respond to messages with AirPods Do we need to add any integration inside app for this or it will directly worked with Siri settings ? Is it possible to do in non messaging App? Is it possible to do without syncing contacts ?

I have been recently getting the following error seemingly randomly, when an event handler of a SwiftUI view accesses a relationship of a SwiftData model the view holds a reference to. I haven't yet found a reliable way of reproducing it: SwiftData/BackingData.swift:866: Fatal error: This model instance was invalidated because its backing data could no longer be found the store. PersistentIdentifier(id: SwiftData.PersistentIdentifier.ID(url: COREDATA_ID_URL), implementation: SwiftData.PersistentIdentifierImplementation) What could cause this error? Could you suggest me a workaround?

Hi There, I have a iOS App which has been published and purely managing data by SwiftData. I use following simple codes everywhere in Views: ... @Query var items: [Item] .... if let firstItem = items.first( where: {...}) { ... Then I encountered crash at Query that _items.wrapperdValue has some errors. Then I tried to split first(where...) into ordinary way: let filteredItems = items.filter(...) if let firstItem = filteredItems.first { ... It runs OK. Is it a bug in SwiftData in 18.2 or I missed some steps to facilitate SwiftData macros?

Hello, I have a problem with Xcode, in C++ language. When I create a new project, I put my program in a file and click Build. It works correctly and without any problems, but when I enter a second file in the same project and click build, it says build failed. In the log it says, duplicate symbols appear.

Hello, everyone! Help me please to find answer. I have two applications: App-1 with share extension and App-2 without it. From the second app I can open share extension via UIActivityViewController. But I need this extension in the second application to open immediately by pressing a button, and not through UIActivityViewController. Can I do this?

Given the below code with Swift 6 language mode, Xcode 16.2 If running with iOS 18+: the app crashes due to _dispatch_assert_queue_fail If running with iOS 17 and below: there is a warning: warning: data race detected: @MainActor function at Swift6Playground/PublishedValuesView.swift:12 was not called on the main thread Could anyone please help explain what's wrong here? import SwiftUI import Combine @MainActor class PublishedValuesViewModel: ObservableObject { @Published var count = 0 @Published var content: String = "NA" private var cancellables: Set<AnyCancellable> = [] func start() async { let publisher = $count .map { String(describing: $0) } .removeDuplicates() for await value in publisher.values { content = value } } } struct PublishedValuesView: View { @ObservedObject var viewModel: PublishedValuesViewModel var body: some View { Text("Published Values: \(viewModel.content)") .task { await viewModel.start() } } }

I have a VPN application published in the app store. Used Ikev2 for this personal VPN. There are two in-app purchases. One is 'Monthly' and another is 'Yearly' with 3 days free trial. We have seen something strange for the yearly subscriptions which has free trail, the cancellation reason through the billing issue is too high like 70-80% due to billing retry state. Some other apps which have billing issues under 10% always. We have done some research and found that if the user doesn't cancel and Apple is unable to charge then it goes to a billing retry state. If users don't like the app, they could cancel their subscription/free trail easily but they are not doing this and why Apple unable to charge the bill after the trial ends. Am i missing something in the developer end?

We are Java application developers and we have a question regarding camera access via WebRTC on iPadOS. Specifically, on iPadOS 17.1, we are encountering an issue when trying to access the camera via the WKWebView API in the Chrome browser, where an error occurs and the camera capture fails. Our investigation suggests that device access through the navigator.mediaDevices property via the WKWebView API may not work in Chrome. However, it works as expected in the Safari browser, leading us to wonder if this is a Chrome-specific limitation, or if it's due to an iPadOS setting or specification. At this point, we are unsure if this issue is related to the WKWebView and WebRTC specifications on iPadOS 17.1, or if there are specific limitations in Chrome. We would appreciate any insights or solutions regarding camera access in iPadOS 17.1 with WKWebView and WebRTC, especially in relation to Chrome.

Hello everyone. macOS, IOBluetooth framework. My goal is to create a temporary SDP service. According to the documentation, by default a temporary service is created (aka Persistent = NO), which is deleted after the application is closed. The documentation also mentions the IOBluetoothRemoveServiceWithRecordHandle function for forced removal of the service. This function is deprecated and is currently unavailable. I guesse that it has been replaced by the IOBluetoothSDPServiceRecord.removeServiceRecord method. The essence of the problem is that the server is not deleted either using removeServiceRecord or even after app closing. That is, if you create several services and try to delete them, they will remain alive. Only turning Bluetooth off and on in the OS helps. I tested all versions of macOS starting with Monteray. The same behavior. for (int i = 0; i < 10; i++) { service = [IOBluetoothSDPServiceRecord publishedServiceRecordWithDictionary:dictionary]; if (!service) { NSLog(@"Failed to create service"); } else { [service getRFCOMMChannelID:&channelID]; [service getServiceRecordHandle:&serverHandle]; NSLog(@"A new service has been created handle=%u, channelID=%hhu", serverHandle, channelID); if (service.removeServiceRecord != kIOReturnSuccess) { NSLog(@"Failed to delete service"); } //service.release; service = nil; } } Can someone confirm this behavior? And is there a solution? A minimal test example is available at the link

Hi In C#, one can define associated functions by the following. Notice that "Declarations DE" is a reference to a function in another C# project file. This lets the compiler know that there are other references in the project. Likewise, "Form_Load" is the entry point of the code, similar to "main" in C. Any calls to related functions can be made in this section, to the functions that have been previously defined above. So I set out trying to find similar information about SwiftUI, and found several, but only offer partial answers to my questions. The YouTube video... Extracting functions and subviews in SwiftUI | Bootcamp #20 - YouTube ... goes into some of the details, but still leaves me hanging. Likewise... SOLVED: Swift Functions In Swift UI – SwiftUI – Hacking with Swift forums ... has further information, but nothing concrete that I am looking for. Now in the SwiftUI project, I tried this... The most confusing thing for me, is where is "main"? I found several examples that call functions from the structure shown above, BUT I have no reason as to why. So one web example on StackOverFlow called the function from position 1. That did not work. Position 2 worked to call the function at position 3, but really, why? All this activity brings up a lot of questions for me, such as: Does SwiftUI need function callouts similar to C#, and they are called out even before running "main". I seem to recall Borland Delphi being this way as well. How does SwiftUI make references to other classes (places where other functions are stored in separate files)? Does SwiftUI actually make use of "main" in the normal sense, i.e. similar to C, C#, Rust and so on? I did notice that once a SwiftUI function is called, it makes reference to data being passed very similar to other languages, at least for the examples I found. Note that I looked at official SwiftUI documentation, but did not come across information that answers the above.

I am using CHCSVParser in objective-c to use the CSVString extension of the Array instance method. When I installed a new app on iOS18.1.1, the correct value (@"Application,"abc,def"") was returned for both the first and second turns, but when I installed a new app on iOS18.2, the correct value was returned for the first turn, but @"" was returned for the second turn. Even when I debug with step into, I can enter the CSVString for the first turn, but I cannot enter it for the second turn and after. It's as if the instance method is not being generated. There are in-app purchases between the first and second turns, but the view controllers that are called are also the same. Is there any change between iOS18.1.1 and iOS18.2?

iOS18.2 / iPhone 16pro / Xcode 16.2 'traitCollectionDidChange' This function has been deprecated since ios17. However, in ios18, when I changed the app to the background state or changed it to the foreground state again, it was confirmed that the function worked. It hasn't been confirmed in ios17, but why is it only confirmed in ios18?

iOS18.2 / iPhone16 pro / xcode16.2 'traitCollectionDidChange' This function has been deprecated in iOS17. However, when I debugged it, I confirmed that it is not called on iOS17, but it is called on iOS18.2. What is the reason?

I just added a .systemLarge widget to my app, but I can't get Links to work. I want the user to be able to tap one of the four rows in my widget - like the EmojiRangers example - but I can't get it to work. I watched a Developer video from WWDC20: https://developer.apple.com/videos/play/wwdc2020/10036?time=223 The guy, Izzy, 'simply' embeds an HStack in a Link, and hey presto! It all works. But that doesn't happen for me. There's clearly some code in the background that runs. I already have .widgetURL working for .systemSmall and .systemMedium widgets, and I don't need to use Links on those two types. Those work by sending a URL to .onOpenURL { incomingURL in ... All good there, no issues. I've wrapped each row in the large widget in a Link with the URL of something like myappurlscheme://widgetTapped/widgetId (it's the same url as that used in the small and medium widgets). I build & run. I tap a row. It doesn't act as though a row is tappable (it doesn't go slightly transparent), and just opens the app without hitting .onOpenURL or anything else. Nothing in my scene delegate is triggered. Is there a specific delegate method that gets called? Do I need to set up some awful intents? I'm not using any sort of NavigationStack here; that model doesn't fit my app. Any ideas? Thanks.

I'm primarily an AppleScript writer and only a novice programmer, using ChatGPT to help me with the legwork. It has helped me to write a functioning app that builds a menu structure based on the scripts I have in the Scripts directory used in the script menu and then runs the applescripts. When I distribute the app to my desktop and run it, the scripts that access other apps, like InDesign will cause it to launch, but not actually do anything. I included the ids for each app in the entitlements dictionary and have given the app full disk access in system settings, but it's not functioning as I'd expect. I know there are apps like Alfred that allow you to run scripts from a keystroke, but I'm building this for others I work with so they can also access info about each script, what it does, and how to use it from the menu, as well as key commands to run them. Not sure what else to say, but if this sounds like a simple fix to anyone, please let me know.

I've been searching all over the web trying to find the proper way to get all records created by a specific user in CloudKit. I am able to get the correct id using: guard let userRecordID = try? await container.userRecordID() else { return } I can see that the id returned is associated with records in my CloudKit dashboard. So I would expect that the following would get those records: let predicate = NSPredicate(format: "%K == %@", #keyPath(CKRecord.creatorUserRecordID), userRecordID) let query = CKQuery(recordType: "CKUser", predicate: predicate) But instead when I use that query it returns nothing. It is successful but with nothing returned... Any ideas why this would be happening? P.S. I have also tried constructing the predicate using the reference, but I get the same result - success with no results. P.S.2 Also worth mentioning that I am trying to get the results from the public database and I have set my CKContainer to the correct container id.

A program I wrote in Swift that uploads and downloads to a private database in iCloud is failing for downloads since the the 15.2 update. It still works for uploads. I.e., I can download uploads made from the program under 15.2 on another computer running the same program under 15.1 The Fetch operation does not return an error, but the returnRecord is empty! I do get the error below after the fact of the failure, don't know if it's related. "ViewBridge to RemoteViewService Terminated: Error Domain=com.apple.ViewBridge Code=18 "(null)" UserInfo={com.apple.ViewBridge.error.hint=this process disconnected remote view controller -- benign unless unexpected, com.apple.ViewBridge.error.description=NSViewBridgeErrorCanceled}" To be clear, I assume I do have access to the database since it works for upload under 15.2, as well as upload and download under 15.1, and from a very similar program on my iPhone (which I haven't updated yet!) Questions? Comments? Thanks!

I noticed that when I enter the fully immersive view and then click the X button below the window, the immersive space remains active, and the only way to dismiss it is to click the digital crown. On other apps (Disney+ for example), closing out of the main window while in immersive mode also closes out the immersive space. I tried applying an onDisappear modifier to the the Modules view with a dismissImmersiveSpace, but that doesn't appear to do anything. Any help would be appreciated.
