Hi I'm new here - I'm trying to learn Swift and SwiftUI. Tried on PluralSight and Udemy but they have been outdated and thus hard to follow. So after finding Apples own guides I felt relieved and happy, but now I'm stuck again. After they've updated Xcode to use #Preview instead of PreviewProvider it's hard to follow along on their tutorial. Does anyone know of good resources to study SwiftUI? Or know if apple plan to update their tutorials any time soon? I'm here now if anyone's interested or it's useful information: https://developer.apple.com/tutorials/app-dev-training/managing-state-and-life-cycle

What is the most obvious method of calling StoreKit from C++. I'm getting blocked by the fact that most of the critical StoreKit calls are async and functions marked a sync don't show up in the swift header for me to call from C++ (at least as far as I can tell). I'm trying to call let result = try await Product.products(for:productIDs) or let result = try await product.purchase() And C++ can't even see any functions I wrap these in as far as I can tell because i have to make them async. What am I missing? I tried a lot of alternates, like wrapping in Task { let result = try await Product.products(for:productIDs) } and it gives me 'Passing closure as a sending parameter' errors. Also when I try to call the same above code it gives me 'initializtion of immutable value never used' errors and the variables never appear. Code: struct storeChooser { public var productIDs: [String] public function checkProduct1 { Task { let result = try await Product.products(for: productIDs) } The above gives the initialization of immutable value skipped, and when I create a @State var products Then I get the 'passing closure as a sending parameter' error when i try to run it in a task it appears if I could make the function async and call it from C++ and have it return nothing it may work, does anyone know how to get C++ to see an async function in the -Swift.h file?

I want to build a Swift library package that uses modified build of OpenSSL and Curl. I have already statically compiled both and verified I can use them in an Objective-C framework on my target platform (iOS & iOS Simulator). I'm using XCFramework files that contain the static library binaries and headers: openssl.xcframework/ ios-arm64/ openssl.framework/ Headers/ [...] openssl ios-arm64_x86_64-simulator/ openssl.framework/ Headers/ [...] openssl Info.plist I'm not sure how I'm supposed to set up my Swift package to import these libraries. I can use .systemLibrary but that seems to use the embedded copies of libssl and libcurl on my system, and I can't figure out how to use the path: parameter to that. I also tried using a .binaryTarget pointing to the XCFramework files, but that didn't seem to work as there is no module generated and I'm not sure how to make one myself. At a basic high level, this is what I'm trying to accomplish: where libcrypto & libssl come from the provided openssl.xcframework file, and libcurl from curl.xcframework

I am currently encountering two deprecated errors in my code. Could someone please identify the issues with the code? Errors: 'init(coordinateRegion:interactionModes:showsUserLocation:userTrackingMode:annotationItems:annotationContent:)' was deprecated in iOS 17.0: Use Map initializers that take a MapContentBuilder instead. 'MapAnnotation' was deprecated in iOS 17.0: Use Annotation along with Map initializers that take a MapContentBuilder instead.

After ther Mac application is launched: Log error: CGSWindowShmemCreateWithPort failed on port 0 and when the application quit: No error handler for XPC error: Connection invalid Appear with Xcode 15.4 but not with 12.4 As repported by Steve4442 in "Can someone explain this message" https://Forums.Developer.Apple.com/Forums/Thread/727803 . The code don't use "windowNumbersWithOptions" Can I ignore this log message ?

Hey everyone, I’m learning async/await and trying to fetch an image from a URL off the main thread to avoid overloading it, while updating the UI afterward. Before starting the fetch, I want to show a loading indicator (UI-related work). I’ve implemented this in two different ways using Task and Task.detached, and I have some doubts: Is using Task { @MainActor the better approach? I added @MainActor because, after await, the resumed execution might not return to the Task's original actor. Is this the right way to ensure UI updates are done safely? Does calling fetchImage() on @MainActor force it to run entirely on the main thread? I used an async data fetch function (not explicitly marked with any actor). If I were to use a completion handler instead, would the function run on the main thread? Is using Task.detached overkill here? I tried Task.detached to ensure the fetch runs on a non-main actor. However, it seems to involve unnecessary actor hopping since I still need to hop back to the main actor for UI updates. Is there any scenario where Task.detached would be a better fit? class ViewController : UIViewController{ override func viewDidLoad() { super.viewDidLoad() //MARK: First approch Task{@MainActor in showLoading() let image = try? await fetchImage() //Will the image fetch happen on main thread? updateImageView(image:image) hideLoading() } //MARK: 2nd approch Task{@MainActor in showLoading() let detachedTask = Task.detached{ try await self.fetchImage() } updateImageView(image:try? await detachedTask.value) hideLoading() } } func fetchImage() async throws -> UIImage { let url = URL(string: "https://via.placeholder.com/600x400.png?text=Example+Image")! //Async data function call let (data, response) = try await URLSession.shared.data(from: url) guard let httpResponse = response as? HTTPURLResponse, httpResponse.statusCode == 200 else { throw URLError(.badServerResponse) } guard let image = UIImage(data: data) else { throw URLError(.cannotDecodeContentData) } return image } func showLoading(){ //Show Loader handling } func hideLoading(){ //Hides the loader } func updateImageView(image:UIImage?){ //Image view updated } }

In scope of one of our project we've faced an issue with constant crashes when integrating C++ library in Swift code using Swift/C++ interoperability. Investigating the root causes of the issue we've discovered that with new version of Swift bug was introduced. Long story short: for strings bigger than 27 symbols memory is feed incorrectly that causes the crashes. By creating this post I wanted to draw community's attention to the problem and promote it to be solved quicker as for now it is not addressed.

I am creating a macOs SwiftUI document based app, and I am struggling with the Window sizes and placements. Right now by default, a normal window has the minimize and full screen options which makes the whole window into full screen mode. However, I don't want to do this for my app. I want to only allow to fill the available width and height, i.e. exclude the status bar and doc when the user press the fill window mode, and also restrict to resize the window beyond a certain point ( which ideally to me is 1200 x 700 because I am developing on macbook air 13.3-inch in which it looks ideal, but resizing it below that makes the entire content inside messed up ). I want something like this below instead of the default full screen green When the user presses the button, it should position centered with perfect aspect ratio from my content ( or the one I want like 1200 x 700 ) and can be able to click again to fill the available width and height excluding the status bar and docs. Here is my entire @main code :- @main struct PhiaApp: App { @NSApplicationDelegateAdaptor(AppDelegate.self) var appDelegate var body: some Scene { DocumentGroup(newDocument: PhiaProjectDocument()) { file in ContentView( document: file.$document, rootURL: file.fileURL ) .configureEditorWindow(disableCapture: true) .background(AppColors.background) .preferredColorScheme(.dark) } .windowStyle(.hiddenTitleBar) .windowToolbarStyle(.unified) .defaultLaunchBehavior(.suppressed) Settings { SettingsView() } } } struct WindowAccessor: NSViewRepresentable { var callback: (NSWindow?) -> Void func makeNSView(context: Context) -> NSView { let view = NSView() DispatchQueue.main.async { [weak view] in callback(view?.window) } return view } func updateNSView(_ nsView: NSView, context: Context) { } } extension View { func configureEditorWindow(disableCapture: Bool = true) -> some View { self.background( WindowAccessor { window in guard let window else { return } if let screen = window.screen ?? NSScreen.main { let visible = screen.visibleFrame window.setFrame(visible, display: true) window.minSize = visible.size } window.isMovable = true window.isMovableByWindowBackground = false window.sharingType = disableCapture ? .captureBlocked : .captureAllowed } ) } } This is a basic setup I did for now, this automatically fills the available width and height on launch, but user can resize and can go beyond my desired min width and height which makes the entire content inside messy. As I said, I want a native way of doing this, respect the content aspect ratio, don't allow to enter full screen mode, only be able to fill the available width and height excluding the status bar and doc, also don't allow to resize below my desired width and height.

A few questions. One, can I safely upgrade to my project to Swift 6.2 without having to require iOS 26+? Two, where do I actually make the upgrade. This is what I see in build settings: 6.2 is not available in the dropdown?

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?

Does anyone know if there will be a Swift 6 version of "The Swift Programming Language" book and if so, when it will be released for Apple Books?

I have a Swift Package that contains an Objective-C target. The target contains Objective-C literals but unfortunately the compiler says "Initializer element is not a compile-time constant", what am I doing wrong? Based on the error triggering in the upper half, I take it that objc_array_literals is on. My target definition looks like: .target( name: "MyTarget", path: "Sources/MySourcesObjC", publicHeadersPath: "include", cxxSettings: [ .unsafeFlags("-fobjc-constant-literals") ] ), I believe Objective-C literals are enabled since a long time but I still tried passing in the -fobjc-constant-literals flag and no luck. To be clear I'm not interested in a run-time initialization, I really want it to be compile time. Does anyone know what I can do?

I came across One Sided Range Example: [...2] [2...] [..<2] Half Open Range [..<2] Can not the last use case be separated [..<2] of One Sided Range for Brevity as it is already included in Half Open Range?

I'm using Network Framework to transfer files between 2 devices. The "secondary" device sends file requests to the "primary" device, and the primary sends the files back. When the primary gets the request, it responds like this: do { let data = try Data(contentsOf: filePath) let priSecDataFilePacket = PriSecDataFilePacket(fileName: filename, dataBlob: data) let jsonData = try JSONEncoder().encode(priSecDataFilePacket) let message = NWProtocolFramer.Message(priSecMessageType: PriSecMessageType.priToSecDataFile) let context = NWConnection.ContentContext(identifier: "TransferUtility", metadata: [message]) connection.send(content: encodedJsonToSend, contentContext: context, isComplete: true, completion: .idempotent) } catch { print("\(error)") } It works great, even for hundreds of file requests. The problem arises if some files being requested are extremely large, like 600MB. You can see the memory speedometer on the primary quickly ramp up to the yellow zone, at which point iOS kills the app for high memory use, and you see the Jetsam log. I changed the code to skip JSON encoding the binary file as a test, and that helped a bit, but it still goes too high; the real offender is the step where it loads the 600MB file into the data var: let data = try Data(contentsOf: filePath) If I remark out everything else and just leave that one line, I can still see the memory use spike. As a fix, I'm rewriting this so the secondary requests the file in 5MB chunks by telling the primary a byte range such as "0-5242880" or "5242881-10485760", and then reassembling the chunks on the secondary once they all come in. So far this seems promising, but it's a fair amount of work. My question: Does Network Framework have a built-in way to stream those bytes straight from disk as it sends them? So that I could send all the data in one single request without having to load the bytes into memory?

PLATFORM AND VERSION iOS Development environment: Xcode 26, macOS 26 Run-time configuration: iOS 18 and up DESCRIPTION OF PROBLEM I am on the beta version of os 26 for both Xcode and macOS. When I try to run my project, which has the Swift OpenAPI Generator from apple, it gives the error "unsupported configuration: the aggregate target 'OpenAPIGenerator' has package dependencies, but targets that build for different platforms depend on it" STEPS TO REPRODUCE Install macOS 26 and Xcode 26 and try running an iOS app built for iOS 18.0 and up wit the OpenAPIGenerator package on a physical iPhone running iOS 26

Hello, Please can you tell me how to create an array of dictionaries? This code below should create 4 dictionaries in an array, but I'm getting these errors: For line "var output = [id: "testID", name: "testName"]": cannot find 'name' in scope Type '(any AnyObject).Type' cannot conform to 'Hashable' For line "return output": Type '(any AnyObject).Type' cannot conform to 'Hashable' var quotes: [(id: String, name: String)] { var output = [[(id: String, name: String)]] () for i in 1...4 { var output = [id: "testID", name: "testName"] } return output }

Hi, I would like to modify an associated value of an existing enum instance of the the following enum: enum FilterItem: Equatable, Hashable { case work(isSelected: Bool) ... var filterName: String { switch self { case .work: return "Work" ... } } var isSelected: Bool { switch self { case .work(let isSelected): return isSelected ... } } I want to be able to switch on the FilterItem type and then to be able to modify the isSelected property of the instance like: let itemToChange: FilterItem switch item { case .work(let isSelected): itemToChange.isSelected = !isSelected I know the above code doesn't compile, but I was wondering if there was a way I could modify my enum instance without creating a totally new enum instance.

I am currently studying the Accelerate library by referring to Apple documentation. Here is the link to the referenced document: https://developer.apple.com/documentation/accelerate/veclib/vforce When I executed the sample code provided at the bottom of the document, I found a case where the results were different. let n = 10_000 let x = (0..&lt;n).map { _ in Float.random(in: 1 ... 10_000) } let y = x.map { return sqrt($0) } and let y = [Float](unsafeUninitializedCapacity: n) { buffer, initializedCount in vForce.sqrt(x, result: &amp;buffer) initializedCount = n } The code below is provided to observe the issue described above. import Accelerate Task { let n = 1//10_000 let x = (0..&lt;n).map { _ in Float(6737.015)//Float.random(in: 1 ... 10_000) } let y = x.map { return sqrt($0) } try? await Task.sleep(nanoseconds: 1_000_000_000) let z = [Float](unsafeUninitializedCapacity: n) { buffer, initializedCount in vForce.sqrt(x, result: &amp;buffer) initializedCount = n } } For a value of 6737.015 when calculating the square root: Using the sqrt(_:) function gives the result 82.07932, While using the vForce.sqrt(_:result:) function gives the result 82.07933. Using a calculator, the value comes out as 82.07932139, which shows that the result from vForce is incorrect. Could you explain the reason behind this difference?

I have a transformation function that takes in data, executes some instructions, and returns an output. This function is dynamic and not shipped with the binary. Currently, I’m executing it using JavaScriptCore.JSContext, which works well, but the function itself is written in JavaScript. Is there a way to achieve something similar using Swift – such as executing a dynamic Swift script, either directly or through other means? I know this is possible on macOS, but I’m not sure about iOS. I’ve also heard that extensions might open up some possibilities here. Any insights or alternative approaches would be appreciated.

Hello, I have a test variable here which works fine: var quotes: [(quote: String, order: Int)] = [ ("I live you the more ...", 1), ("There is nothing permanent ...", 2), ("You cannot shake hands ...", 3), ("Lord, make me an instrument...", 4) ] and I have a test function which successfully pulls data from a mysql database via a web service and displays it via the "print" function: func getPrice(){ if let url = URL(string:"https://www.TEST.com/test_connection.php"){ URLSession.shared.dataTask(with: url) { (data, response, error) in if let data = data{ if let json = try? JSONDecoder().decode([[String:String]].self, from: data){ json.forEach { row in print(row["quote"]!) print(row["order"]!) } } else{ } } else{ print("wrong :-(") } }.resume() } } Please can you tell me how to re-write the quotes variable/array so that it returns the results that are found in the getPrice() function?
