I was switching the Detector scanner from QR to Rectangle type of detection but on Rectangle type of detection I cannot take the feature.messageString out of CIRectangleFeature, while on CIQRCodeFeature it works. Only what I had changed was ofType: CIDetectorTypeQRCode into CIDetectorTypeRectangle and features as? [CIQRCodeFeature] into features as? [CIRectangleFeature] here is the code func processQRCodeImage(_ image: UIImage) { var qrCodeLink = "" let detector: CIDetector = CIDetector(ofType: CIDetectorTypeRectangle, context: nil, options: [CIDetectorAccuracy: CIDetectorAccuracyHigh])! let ciImage: CIImage = CIImage(image: image)! let features = detector.features(in: ciImage) if let features = features as? [CIRectangleFeature] { for feature in features { qrCodeLink += feature.messageString! // Value of type 'CIRectangleFeature' has no member 'messageString' COMPILE ERROR } } if qrCodeLink.isEmpty { failedQRCoderead() } else { found(code: qrCodeLink) onBackPressed?() } }

For some reason the AVAssetTrack nominalFrameRate is always 30 for high speed videos. 120 FPS and 240 FPS videos' nominalFrameRate property is always 30. However, 60 FPS videos' nominalFrameRate is 60. I'm reading in the video url through the PHPickerViewController. I have a configuration for the picker set up as follows. configuration = PHPickerConfiguration(photoLibrary: PHPhotoLibrary.shared()) configuration.filter = .videos configuration.selectionLimit = 0 and the gathering of the picker results as follows func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) { for result in results { var currentVideo = Video() let provider = result.itemProvider provider.loadFileRepresentation(forTypeIdentifier: "public.movie") { url, error in guard error == nil else { return } guard let url = url else {return} // create a new filename let fileName = "\(Int(Date().timeIntervalSince1970)).\(url.pathExtension)" let newUrl = URL(fileURLWithPath: NSTemporaryDirectory() + fileName) // copy item to APP Storage try? FileManager.default.copyItem(at: url, to: newUrl) currentVideo.url = newUrl.absoluteString self.parent.selectedVideos.append(currentVideo) } } // Set isPresented to false because picking has finished. parent.isPresented = false } I'm creating an AVAsset and AVAssetTrack to check the FPS of the video as follows. var asset: AVAsset? = AVAsset(url: url) if let asset = asset, let videoTrack = try? await asset.loadTracks(withMediaType: .video).last { let size = try? await videoTrack.load(.naturalSize) let fps = try? await videoTrack.load(.nominalFrameRate) let duration = try? await test.load(.duration) print(fps) // This shows 30 for 120 fps and 240 fps videos } I'm not sure if there's some other configuration that needs to be set to handle high speed videos or what. I'm really confused.

I have an app that supports English and Arabic. If a German user has Arabic in the languages for their iPhone, the app is switching to Arabic, since that language is one of their languages. How do I get it to only use the top most language (their most preferred language) they have set? So a German user that does not have English in their languages or maybe has it below Arabic, will still get English as their language

I must be missing something simple here. I have an application I'm writing and having trouble with shifts and 64 bit unsigned integers. Here's some playground code: import UIKit let a: UInt64 = 0xFFFFFFFF00000000 let b: UInt64 = 0x0000000000000000 print(String(format: "a = 0x%016X", a)) print(String(format: "b = 0x%016X", b)) print(String(format: "a | b = 0x%016X", a | b)) It produces this output: a = 0x0000000000000000 b = 0x0000000000000000 a | b = 0x0000000000000000 Why is "a" not equal to 0xFFFFFFFF00000000? I'm using XCode 14.3.1. I also found issues shifting a byte into the upper 32 bits of a UInt64: let c: UInt64 = 0x00000000000000FF let d: UInt64 = 0x0000000000000000 print(String(format: "c = 0x%016X", c)) print(String(format: "d = 0x%016X", d)) print(String(format: "d | (c << 32) = 0x%016X", d | (c << 32))) This produces this output: c = 0x00000000000000FF d = 0x0000000000000000 d | (c << 32) = 0x0000000000000000

From the fantastic video: https://developer.apple.com/videos/play/wwdc2023/10170/?time=298, would you have a downloadable link to that kitchen service project? I'm trying to understand how the method: func handleShift<Orders>(orders: Orders) async throws is called? Because the video shows it to be called this way: for cook in staff.keys { group.addTask { try await cook.handleShift() } } without arguments ... Many thanks!

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 ?

I have a WebView based iOS project where the keyboard is not rendering as expected on iOS 17 but works fine on devices with iOS 15,16. Attached are the images from simulator and device. Please help. I tried setting WebView contentInset in keyboardWillShow() but it did not work.

I'm a beginner in swift. Ways I tried: Tried adding a command line tool DNC observer to call a function when any screen sharing notification triggers, but later came to know that screen sharing doesn’t give any notifications. import OSLog import Foundation os_log("TecMFA:: Starting screen sharing finder.") let dnc = DistributedNotificationCenter.default() dnc.addObserver( forName: .init("com.apple.screensharing.server"), // tried many notification names like com.apple.screensharing.curtain etc. object: nil, queue: .main ) { notification in os_log("TecMFA:: Started screen sharing deamon.") } dispatchMain() Created a server using vapor as following //configure.swift import Vapor func routes(_ app: Application) throws { // Define a route to handle POST requests to "/login" app.post("login") { req -> HTTPStatus in // Read the username and password from the request body guard let loginData = try? req.content.decode(LoginData.self) else { // Failed to parse request body or invalid data return .badRequest } let username = loginData.username let password = loginData.password print(username) print(password) // Do something with the username and password print("Received login request with username: \(username) and password: \(password)") // Return a success response return .ok } } // Define a struct to represent the request body data struct LoginData: Content { let username: String let password: String } // routes.swift import Vapor import Foundation func getLocalIPAddress() -> String? { let task = Process() task.launchPath = "/usr/sbin/ipconfig" task.arguments = ["getifaddr", "en0"] // Use "en0" for Wi-Fi, "en1" for Ethernet let pipe = Pipe() task.standardOutput = pipe task.launch() let data = pipe.fileHandleForReading.readDataToEndOfFile() let output = String(data: data, encoding: .utf8)?.trimmingCharacters(in: .whitespacesAndNewlines) return output } // Called before your application initializes. public func configure(_ app: Application) throws { // Register routes try routes(app) // Get the local IP address guard let localIPAddress = getLocalIPAddress() else { fatalError("Unable to get the local IP address.") } // Update the server configuration to bind to the local IP address and desired port app.http.server.configuration.hostname = localIPAddress app.http.server.configuration.port = 8080 } It didn't work when same port numbers. I tried using different port numbers but the request comes through port 5900, so 8080 cannot access it, so it didn't work either. Any corrections and suggestions are welcome.

I am learning how to access SQLite without the use of Swift Data. I have a function that tests to see if a table exists and it works. The problem is that I do not understand why it works. It is my understanding that the SELECT statement returns a 0 if the table does not exist and 1 if it does. But the API step statement returns 101 (SQLITE_Done) if the table does not exist. But if the table does exist it does not return 101. Per the SQLite documentation it would appear that 101 means the operation has completed. What am I missing here and is there a way to capture the underlying SQLite 0 or 1 which would allow me to test for that? Below is my function. func doesTableExist(db: OpaquePointer?) -> Bool { var tableExists: Bool = true let testForTable = """ SELECT name FROM sqlite_master WHERE type='table' AND name='Contact'; """ var testForTablePtr: OpaquePointer? if sqlite3_prepare_v2(db, testForTable, -1, &testForTablePtr, nil) == SQLITE_OK { if sqlite3_step(testForTablePtr) == SQLITE_DONE { tableExists = false } } else { print("unable to compile sql statement testing to see if table exists") } return tableExists }

Hello guys! I am trying to run my application on a physical iPad device. The app is successfully installed and when I run the code, it "Builds successfully", but when it starts, the screen is just dark and on the Xcode file it says "Paused app on iPad". i don't know what else to do. can anyone help me with this? Thank you!

Recently, we are testing our app on iOS 17, and found a weird crash that occurred on iOS 17, not on iOS 16 and below. Here's the stack: the sha512 is a function we wrote for the String extension: public extension String { var sha512: String? { return self.data(using: .utf8).map { NSData(data: $0).sha512() } } } We cannot find any mistake from the code above, and the code works well on iOS 16 and below (packaged by Xcode 14.2). And it also works on: iOS 17 simulator running from Xcode 14.2. iOS 17 simulator running from Xcode 15 Beta 4. iOS 17 beta 3/4 real device running from Xcode 15 Beta 4 (debug). It doesn't works on: packaged by Xcode 14.2 and running on iOS 17 beta real device. not tested: packaged by Xcode 15 Beta and running on iOS 17 beta real device. Is that an iOS 17 bug? Or anyone may know how to fix that? I will very appreciate your advice, thank you.

I've been trying to get the bash/script version of DeepFaceLab to work with Apple Silicon Macs, but this was original a Windows project that even now has non-existent support for MacOs/Apple Silicon. I am thinking of converting everything into a native macOS app using Swift, specifically optimized for Apple Silicon GPUs. Here's what I got from ChatGPT. Any help/advice on how to do this would be greatly appreciated. I don't have any Swift programming experience, but I have experience with some coding and can generally figure things out. I know that this is probably not feasible for a single individual with little programming experience, but I wanted to throw this out there to see what others think. Thank you Here's a high-level overview of the steps involved in porting DeepFaceLab to Swift with a graphical UI: Understand DeepFaceLab: Thoroughly study the DeepFaceLab project, its Python scripts, and the overall architecture to grasp its functionalities and dependencies. Choose a Swift Framework: Decide on the UI framework you want to use for the macOS app. SwiftUI is Apple's latest UI framework that works across all Apple platforms, including macOS. Alternatively, you can use AppKit for a more traditional approach. Rewrite Python to Swift: Convert the Python code from DeepFaceLab into Swift. You'll need to rewrite all the image processing, deep learning, and video manipulation code in Swift, potentially using third-party Swift libraries or native macOS frameworks. Deep Learning Integration: Replace the Python-based deep learning library used in DeepFaceLab with an appropriate Swift-compatible deep learning framework. TensorFlow and PyTorch both offer Swift APIs, but you may need to adapt the specific model implementation to Swift. Image Processing: Find equivalent Swift libraries or frameworks for image processing tasks used in DeepFaceLab. UI Development: Design and implement the graphical user interface using SwiftUI or AppKit. You'll need to create views, controls, and navigation elements to interact with the underlying Swift code. Integration: Connect the Swift code with the UI components, ensuring that actions in the GUI trigger the appropriate Swift functions and display results back to the user. Testing and Debugging: Rigorously test the Swift application and debug any issues that arise during the porting process. Optimization: Ensure that the Swift app performs efficiently and effectively on macOS devices.

I have a MacOS menu bar application and I'm trying to display an NSPopover in the center of the screen. This is the code I've come up with so far: class AppDelegate: NSObject, NSApplicationDelegate, ObservableObject { private var statusItem: NSStatusItem! private var popover: NSPopover! @MainActor func applicationDidFinishLaunching(_ notification: Notification) { // ... init of statusItem hidden self.popover = NSPopover() self.popover.contentSize = NSSize(width: 300, height: 300) self.popover.behavior = .transient self.popover.contentViewController = NSHostingController(rootView: ContentView()) } @objc func togglePopover() { if let button = statusItem.button { if popover.isShown { self.popover.performClose(nil) } else { if let screen = NSScreen.main { let screenFrame = screen.visibleFrame let x = screenFrame.origin.x + (screenFrame.width - self.popover.contentSize.width) / 2 let y = screenFrame.origin.y + (screenFrame.height - self.popover.contentSize.height) / 2 let centerPoint = NSPoint(x: x, y: y) popover.show(relativeTo: NSRect(origin: centerPoint, size: CGSize.zero), of: screenFrame, preferredEdge: NSRectEdge.minX) } } } } } Unfortunately the code above does not compile because the of parameter of popover.show expects an NSView, whereas screenFrame is an NSRect. I've tried creating a view out of the rect but this leads to a run-time error that the view is not contained within a window. Any thoughts?

what is the easiest way to make passkey from app?I have searched every where I could, but there is no tutorial on how to generate passkey from app itself.

I am trying to develop new XCUITest project and my requirement is to do parallel distributed testing. Such that i have 4 iPhones and 6 classes. Each class should run once and if it is executed then it should not be executed on any other iPhone. Example: class to be executed: Class1, Class2, Class3, Class4, Class5, Class6 No of iPhones: iPhone1, iPhone2, iPhone3, iPhone4 Now execution should be like this iPhone1: Class1, Class5 iPhone2: Class2, Class6 iPhone3: Class3 iPhone4: Class4 I have tried test plan, fastlane & xcodebuild still not able to find the solution. Does anyone has any idea how can we achieve this or if someone has implemented this in their project. Any help would be great.

Hello, I'm developing a MacOS application in which I want to store some credentials on the keychain. The implementation is working, but anytime I run the application to test after I made some changes to the code, the keychain requests to enter my password. Seems like "Always allow" only works until I change the code. It is really annoying, because it is slowing down my development significantly. Any time I make UI changes, if I want to test it I need to enter my 20 character long password... My application loads data from the network, and the credentials are required every time I run the app, so I can't really disable the keychain during development (or not easily at least)... Is it possible to make my application as "trusted" during development, so I don't need to enter my password to retrieve the credentials from Keychain? For reference, I created a GitHub repo that demonstrates the problem: https://github.com/ferenc-nagy/macos-swift-keychain-experiment Each time I change the text in this UI element, I will have to re-enter my password when running the app: https://github.com/ferenc-nagy/macos-swift-keychain-experiment/blob/main/KeychainExperiment/Views/ContentView.swift#L15
