why are people having problems with the playground download when some people have full access to it What is the difference between us and other people who have it

In the Swift function at the end of this post, I use Scripting Bridge to have Finder delete a path. The variable result is a SBObject returned by the delete() function. I know that result somehow contains the new path of the deleted item in the trash folder, but I don't know how to nicely extract it as a single String. If I print(String(describing: result)), I get output like: <SBObject @0x0123456789ab: <class 'appf'> "AppName.app" of <class 'cfol'> ".Trash" of <class 'cfol'> "user" of <class 'cfol'> "Users" of startupDisk of application "Finder" (822)> Is there any way to obtain the String "/Users/user/.Trash/AppName.app" from result without having to perform string parsing on the above output? The Finder* types in the code below are from https://github.com/tingraldi/SwiftScripting/blob/master/Frameworks/FinderScripting/FinderScripting/Finder.swift func trash(path: String) throws { guard let finder: FinderApplication = SBApplication(bundleIdentifier: "com.apple.finder") else { throw runtimeError("Failed to obtain Finder access: com.apple.finder does not exist") } guard let items = finder.items else { throw runtimeError("Failed to obtain Finder access: finder.items does not exist") } let object = items().object(atLocation: URL(fileURLWithPath: path)) guard let item = object as? FinderItem else { throw runtimeError( """ Failed to obtain Finder access: finder.items().object(atLocation: URL(fileURLWithPath: \ \"\(path)\") is a '\(type(of: object))' that does not conform to 'FinderItem' """ ) } guard let delete = item.delete else { throw runtimeError("Failed to obtain Finder access: FinderItem.delete does not exist") } let result = delete() }

As the title states, this severely limits the flexibility of multi-window applications in creating a good user experience. Even effects like the ones shown below cannot be achieved.

Is anyone else seeing their apps crash on iOS/macOS 17.4/14.4 and newer when building a project that simply just includes the iOS 18 @AssistantIntent Macro? The beta 4 releases still have this problem. There are no notes about this that I have seen in the beta release notes. Crash message shown in console when trying to run on 17.4, 17.5, 17.5.1, etc: dyld[21935]: Symbol not found: _$s10AppIntents15AssistantSchemaV06IntentD0VAC0E0AAWP Referenced from: <F7A1FEF0-F3B0-379C-A914-D1FB0BA7C693> /Users/jonathan/Library/Developer/CoreSimulator/Devices/CA308F47-BCA8-4429-8599-1BB1CCEAB5B6/data/Containers/Bundle/Application/D7DC8E16-90DB-406A-A521-20F18326E4A7/IntentDemo.app/IntentDemo.debug.dylib Expected in: <88E18E38-24EC-364E-94A1-E7922AD247AF> /Library/Developer/CoreSimulator/Volumes/iOS_21F79/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 17.5.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/AppIntents.framework/AppIntents Obviously, the new Apple Intelligence AssistantIntents only work on the 2024 OS releases. However, even when these new App Intents are marked with @available(iOS 18, macOS 15, *), the app crashes on any earlier OS version. But it runs just fine on iOS 18 and macOS 15... I would love for me to just have done something wrong but I don’t think I have… Here is the sample project: https://github.com/JTostitos/FB14323923 Maybe it's a compiler issue thats failing to strip out the macro when building for older OS's or an Xcode issue - I have no idea. I just would like to know why its not working and how to resolve it. Thanks in advance for anyones help...

Hello, I'm working with the Network framework in Swift and have encountered an issue when attempting to create multiple NWListener instances on the same port. I am specifically trying to set the allowLocalEndpointReuse property on the NWParameters used for both listeners, but it seems that even with this property set, the second listener fails to start. Here’s a simplified version of my implementation: import Foundation import Network class UDPServer { private var listener1: NWListener? private var listener2: NWListener? private let port: NWEndpoint.Port init(port: UInt16) { self.port = NWEndpoint.Port(rawValue: port) ?? NWEndpoint.Port(45000) startListeners() } private func startListeners() { let udpOptions = NWProtocolUDP.Options() let params = NWParameters(udp: udpOptions) params.allowLocalEndpointReuse = true // Create first listener do { listener1 = try NWListener(using: params, on: port) listener1?.start(queue: .global()) } catch { print("Failed to create Listener 1: \(error)") } // Create second listener do { listener2 = try NWListener(using: params, on: port) listener2?.start(queue: .global()) } catch { print("Failed to create Listener 2: \(error)") } } } // Usage example let udpServer = UDPServer(port: 45000) RunLoop.main.run() Observations: I expect both listeners to operate without issues since I set allowLocalEndpointReuse to true. However, when I attempt to start the second listener on the same port, it fails with an error. output nw_path_evaluator_evaluate NECP_CLIENT_ACTION_ADD error [48: Address already in use] nw_path_create_evaluator_for_listener nw_path_evaluator_evaluate failed nw_listener_start_on_queue [L2] nw_path_create_evaluator_for_listener failed Listener 1 ready on port 45000 Listener 2 failed: POSIXErrorCode(rawValue: 48): Address already in use Listener 2 cancelled Questions: Is there a limitation in the Network framework regarding multiple listeners on the same port even with allowLocalEndpointReuse? Should I be using separate NWParameters for each listener, or is it acceptable to reuse them? Even when trying to initialize NWParameters with NWProtocolUDP.Options, it doesn't seem to change anything. What steps should I take to modify these properties effectively? If I wanted to set the noDelay option for TCP, how would I do that? Even when initializing NWParameters with init(.tls: , .tcp:), it doesn't seem to have any effect. Any insights or recommendations would be greatly appreciated! Thank you!

I was curious as to the procedure for having an encryption key leaked and was hoping to have your opinions on how these two questions will be answered [if you were in the position]. Q1: Let's say, for instance, that you're making a social media network that stores private messages in a database network (such as Firebase) and uses basic encryption to store that data into an encrypted format (e.g., text message: "Hello Mous772!"; Firebase data: "deaErG5gao7J5qw/QI3EOA=="). But oh no! Someone got access to the encryption key used to encrypt hundreds of thousands of messages. You cannot simply delete thousands of messages because of this hacker, so how should you deal with this? This is where my question comes in. Is it possible to change the encryption key for all of the data if I am using the code system at the bottom of this question and using that code system to store encrypted data in Firebase? If so, how would you go about doing that? (Please use simple language; I'm not good with this stuff). Q2: What, in your opinion, is the best way to prevent this in the first place? I was told that a good solution was to store two sets of the same data; when one kegs it, we shut down the original and use the backup; however, this does not sound sustainable at all. I want to know what steps can be taken to ensure this never happens. [Please don't give me "Well... you can never *really hide these keys!" I'm well aware it's not possible to never have them leaked ever; I'm just looking for best practices only.] This is the encryption system we are using for this hypothetical app. // MARK: Value // MARK: Private private let key: Data private let iv: Data // MARK: - Initialzier init?(key: String, iv: String) { guard key.count == kCCKeySizeAES128 || key.count == kCCKeySizeAES256, let keyData = key.data(using: .utf8) else { debugPrint("Error: Failed to set a key.") return nil } guard iv.count == kCCBlockSizeAES128, let ivData = iv.data(using: .utf8) else { debugPrint("Error: Failed to set an initial vector.") return nil } self.key = keyData self.iv = ivData } // MARK: - Function // MARK: Public func encrypt(string: String) -> Data? { return crypt(data: string.data(using: .utf8), option: CCOperation(kCCEncrypt)) } func decrypt(data: Data?) -> String? { guard let decryptedData = crypt(data: data, option: CCOperation(kCCDecrypt)) else { return nil } return String(bytes: decryptedData, encoding: .utf8) } func crypt(data: Data?, option: CCOperation) -> Data? { guard let data = data else { return nil } let cryptLength = data.count + key.count var cryptData = Data(count: cryptLength) var bytesLength = Int(0) let status = cryptData.withUnsafeMutableBytes { cryptBytes in data.withUnsafeBytes { dataBytes in iv.withUnsafeBytes { ivBytes in key.withUnsafeBytes { keyBytes in CCCrypt(option, CCAlgorithm(kCCAlgorithmAES), CCOptions(kCCOptionPKCS7Padding), keyBytes.baseAddress, key.count, ivBytes.baseAddress, dataBytes.baseAddress, data.count, cryptBytes.baseAddress, cryptLength, &bytesLength) } } } } guard Int32(status) == Int32(kCCSuccess) else { debugPrint("Error: Failed to crypt data. Status \(status)") return nil } cryptData.removeSubrange(bytesLength..<cryptData.count) return cryptData } } //let password = "UserPassword1!" //let key128 = "1234567890123456" // 16 bytes for AES128 //let key256 = "12345678901234561234567890123456" // 32 bytes for AES256 //let iv = "abcdefghijklmnop" // 16 bytes for AES128 //let aes128 = AES(key: key128, iv: iv) //let aes256 = AES(key: key256, iv: iv) //let encryptedPassword128 = aes128?.encrypt(string: password) //aes128?.decrypt(data: encryptedPassword128) //let encryptedPassword256 = aes256?.encrypt(string: password) //aes256?.decrypt(data: encryptedPassword256)

I am able to play a video on a plane in ARKit. But, I need to remove its background, presumably using a chromaKey technique. how do I do that? I have spent more time than is reasonable searching the docs and the internet, but to no avail. ChatGPT useless of course. Surely it is doable; even the react native library for ARKit has it.

Hi, is there any way to interact with the eye tracking accessibility feature in iOS and iPadOS? I want to be able to trigger an eye tracker recalibration programmatically. Also if possible, I would like to be able to retrieve gaze location data. These are not intended to be features on an app being published to the app store but rather a custom made accessibility app.

Hey there, Create Live activity in my project, after executing the creation method, back to the background, real-time activity UI is not displayed, but click Smart Island is effective, now do not know where the problem appears? Has anyone experienced this problem？ Thanks

I've got quite a problem as I've created a Localizible file with String catalog for my iOS app. For testing it out I've added lots of different languages and they all appeared in App settings. However, I need to remove most of them and they are still visible in the settings. What I tried so far: I have deleted EVERYTHING that had word localizable, localizations and etc. From Project Info also all the languages were removed and left only English and French. I also deleted my app, restarted the phone, downloaded the version without localizations from the app store and then install debug version (languages still appeared)

I need to connect to a JMS that publishes data that I need to collect. I am trying one solution: RabbitMQ with the JMS plugin. I succeeded to install RabbitMQ and send messages from one process to another. However, I need to consume a JMS that an external party publishes. Can anybody tell me how I should configure the Host, Port, Username, Password and Queue name for RabbitMQ/JMS so that I can consume (or subscribe to) that JMS? Or does anybody know another way to consume (or subscribe to) a JMS from Swift? I have no idea which of the provided Tags I should select. Thanks! Wouter

I am using a Key to connect my notification server with APNS in order to send out notifications to users. I have recently added notifications to a second app of mine, using the same notification server to fire off notifications for both apps. However, any notifications going to the second app return the error InvalidProviderToken, where as I get no such issues when send notifications to the first app. Everything, including the payloads, are exactly the same between the two apps, the only difference is that the device IDs are attached to different apps. Does anyone know why/how this would happen and how I can resolve it?

I have a workspace with my project and a Swift Macro.

I have already searched for a lot of information about this issue. Many people have encountered it with UISplitViewController or on iPadOS, but I am experiencing this problem on iOS 18. It does occasionally occur on iOS 17, but it definitely happens on iOS 18. The error messages are as follow: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Layout requested for visible navigation bar, <UINavigationBar: 0x14a6b3c00; frame = (0 44; 375 44); autoresize = W; tintColor = UIExtendedGrayColorSpace 1 1; layer = <CALayer: 0x3026a9da0>> delegate=0x14a674600 standardAppearance=0x300d1d0a0 scrollEdgeAppearance=0x300d1cf50, when the top item belongs to a different navigation bar. topItem = <UINavigationItem: 0x14a7f8780> style=navigator leftBarButtonItems=0x302423b40, navigation bar = <UINavigationBar: 0x14adcb700; frame = (0 0; 375 44); autoresize = W; tintColor = UIExtendedGrayColorSpace 1 1; layer = <CALayer: 0x302680940>> delegate=0x14ade8c00 standardAppearance=0x300d7a7d0 scrollEdgeAppearance=0x300d7a610, possibly from a client attempt to nest wrapped navigation controllers.' *** First throw call stack: (0x193f3a08c 0x191242698 0x19330a8fc 0x196939290 0x1966847b4 0x1967cdc88 0x1959ba6d8 0x1966c86bc 0x196769d50 0x1967cae58 0x196771f28 0x196b0fcb8 0x196764800 0x196684280 0x1959ba6d8 0x1959ba264 0x195a12edc 0x195990560 0x1968295f0 0x193f1c218 0x193f0a4c0 0x193f09b84 0x193f09368 0x1e00fc1c4 0x196a569b0 0x196b04d54 0x10462b1fc 0x1ba144734) libc++abi: terminating due to uncaught exception of type NSException I am sure about the process on iOS 17, first I use UINavigationController.present(UINavigationController()) and then call keyWindow.rootViewController = UINavigationController(), it crashes.

Hello, I have written the following app intent and I can access it via shortcuts. But I can't get Siri to pick it up. I want it to have a dynamic book title (which could be anything) so that the user can say "Add (bookname) to my (app name). I need it to work for ios 17.1 onwards. I have added siri as a capability for my ios app. import AppIntents struct AddBookToReadingListIntent: AppIntent { static var title: LocalizedStringResource = "Add my Book" @Parameter(title: "Book Title", requestValueDialog: "What's the title of the book you want to add?") var bookTitle: String static var parameterSummary: some ParameterSummary { Summary("Add my '\(\.$bookTitle)'") } func perform() async throws -&gt; some IntentResult &amp; ReturnsValue&lt;String&gt; { return .result(value: "Added '\(bookTitle)' to your app") } } struct AppShortcuts: AppShortcutsProvider { static var appShortcuts: [AppShortcut] { AppShortcut( intent: AddBookToReadingListIntent(), phrases: [ "Add \(\.$bookTitle) in \(.applicationName)" ], shortTitle: "Add Book to app name", systemImageName: "book" ) } }

When first opening my app, the first view navigated to loads and then a second later reloads. When navigating away and back to the view, it only loads once as designed. Has anyone ever experienced this before and knows of any obvious reasons? I can upload code snippets later, the views are wrapped in navigation links. Thanks for any help

Hi there, I'm having an app developed in the last weeks, and recently I'm testing it on iOS 18. This following piece of UI code has diff between iOS 18 and iOS version lower than 18. I have a NavigationStack in my homeView, and the display difference is for its toolbar in one destination. I've tried both approaches in code, with header variable or ToolbarItemGroup used directly in the toolbar modifier, both would result in there being a spacer between the body VStack and toolbar, which is unexpected. Here's the code and a demo screenshot. var body: some View { // header VStack(alignment: .leading) { notificationView( iconKey: "ErrorCircle", contentKey: "receivedFile.notification.noNetwork.content" ) fileListView } .toolbar { // header ToolbarItemGroup(placement: .principal) { Button { dismiss() } label: { Image(systemName: "chevron.backward") } .background(Color.yellow) Spacer() Text(LocalizedStringKey("title")) .font( .system(size: 17) .weight(.semibold) ) .background(Color.yellow) Spacer() Button { print("click") } label: { Text("Click") } .background(Color.yellow) } } .navigationBarBackButtonHidden() .onAppear { refreshAllFiles() } } @ToolbarContentBuilder private var header: some ToolbarContent { ToolbarItem(placement: .topBarLeading) { Button { dismiss() } label: { Image(systemName: "chevron.backward") } .background(Color.yellow) } ToolbarItem(placement: .principal) { Text(LocalizedStringKey("receivedFileList.title")) .font( .system(size: 17) .weight(.semibold) ) .background(Color.yellow) } ToolbarItem(placement: .topBarTrailing) { Button { print("click for jumping") } label: { Text("Click for jumping") } .background(Color.yellow) } } Hope I can get some help from the forum on the usage. If not fixable, may I know if this is a known issue that would be fixed in the next upgrades.
