Reoccurring data access prompt issue with Swift Playgrounds 4.6.4 on macOS 26.1
Hello, I am having a recurring issue using Swift Playgrounds version 4.6.4 on macOS 26.1. Upon opening a file and every other time I start typing in the code section I get a prompt, the image below, two or three times. It doesn't matter if I accept or decline all or some of the prompts, as soon as I start typing on another line I get prompted another two or three times for permission. It appears to me that prompt generates every time the preview pane tries to update. Declining the prompt breaks the preview but accepting the prompt only gets you through a single line of code before it appears again. I believe this issue started after I updated to macOS26.1 as I had not encountered it before. I've also opened other files with Swift Playgrounds and encounter the same problem. It could also be unrelated to the update and could be an issue with some permission setting somewhere, however, I have been unable to find what or where it could be. Is anyone else experiencing this? Thank you for your time :)

Playgrounds app with the latest SDK (OS 26)
I am preparing for Swift Student Challenge, but it seems like the iPad Playground app still not support the latest SDK. I can't use frameworks like FoundationModel, etc., directly in playground app My playground for this year would require iPad environment since it uses PencilKit, ARKit, etc., and I also want to use the latest tech + the liquid glass UI Right now, I develop the project as a normal Xcode project, and I am wondering how do I post it? As Xcode playground, it must run on macOS As Swift Playground project, the iPad version of Playground does not support latest APIs and it can't compile

“Keep Going with Apps” Tutorial section will not complete.
Hello All, I am currently working through ”Keep going with Apps” in Swift Playground. The section in the tutorial “Add a DancingCreature view” will not complete. I have tried to type it is as written in the tutorial and even used the copy and paste button provided. I have restarted the app and my IPad with no success. I have attached a screen shot of the tutorial prompt. Here is the code block: import SwiftUI import Guide struct DancingCreatures: View { //#-learning-code-snippet(varDeclaration) @EnvironmentObject var data : CreatureZoo var body: some View { SPCAssessableGroup(view: self) { VStack { ZStack { /*#-code-walkthrough(dance.forEach)*/ ForEach(data.creatures) { creature in /*#-code-walkthrough(dance.forEach)*/ /*#-code-walkthrough(dance.textView)*/ Text(creature.emoji) .resizableFont() .offset(creature.offset) .rotationEffect(creature.rotation) /*#-code-walkthrough(dance.textView)*/ } } ZStack { /*#-code-walkthrough(dance.forEach)*/ ForEach(data.creatures) { creature in /*#-code-walkthrough(dance.forEach)*/ /*#-code-walkthrough(dance.textView)*/ Text(creature.emoji) .resizableFont() .offset(creature.offset) .rotationEffect(creature.rotation) /*#-code-walkthrough(dance.textView)*/ //#-learning-code-snippet(exp1) //#-learning-code-snippet(animationSolution) //#-learning-code-snippet(exp3) } } /*#-code-walkthrough(dance.onTap)*/ .onTapGesture { data.randomizeOffsets() } /*#-code-walkthrough(dance.onTap)*/ /*#-code-walkthrough(dance.onTap)*/ .onTapGesture { data.randomizeOffsets() } /*#-code-walkthrough(dance.onTap)*/ } } } } struct DancingCreatures_Previews: PreviewProvider { static var previews: some View { DancingCreatures().environmentObject(CreatureZoo()) } } Device information: IPad Pro (11 inch, 2nd gen) iPad OS Version: 26.0.1 Playground Version: 4.6.4 Anyone else come across this? Thank you in advance.

Swift Playgrounds macOS repeatedly asks “My App would like to access data from other apps”
Environment: Swift Playgrounds (macOS) SwiftUI App Preview macOS version: 26.2 (25C56) Issue: In Swift Playgrounds on macOS, the app repeatedly shows the system permission dialog: “My App would like to access data from other apps. Keeping app data separate makes it easier to manage your privacy and security.” Steps to Reproduce: Create a new SwiftUI app in Swift Playgrounds. Run the SwiftUI App Preview. When the permission dialog appears, click “Allow”. Expected Result: The permission should be granted once and persist, allowing the preview to continue normally. Actual Result: After clicking “Allow”, the SwiftUI App Preview crashes and restarts. When the preview restarts, the same permission dialog appears again. This repeats indefinitely, creating a loop. Notes: This occurs even when no explicit file system or inter-app data access code is written. The permission choice does not appear to persist between preview restarts. Question: Is this a known limitation of Swift Playgrounds sandboxing or SwiftUI App Preview? Is there an official workaround or recommended approach to avoid this behavior while using Swift Playgrounds?

Am I allowed to use Speech framework on Swift Student Challenge?
Hello! I would like to use Speech Framework on my App Playground for this year challenge. But I still can't understand if I am allowed to use it to respect the rule of "not rely on a network connection". That's why: Speech framework can use on-device Speech recognition – No internet connection needed ✅. But it can ask to download an Apple's native language package to use it for this on-device recognition – To get this, you need to be connected to the Internet ❌. When I try to add a Speech Recognition Capabilities on my App Playground, its' description says: "Required to perform speech recognition using Apple's servers." (screenshot is attached). Does it mean that I won't be able to use on-device recognition on my App Playground? – And therefore, only online-version of this framework is available and I can't use it to participate on the challenge successfully❓. If it's possible, could you please make it clearer? This framework is crucial for my App Playground and I really need this to make it work. Thanks for your help in advance! And a have a good day!

Swift Playgrounds Incompatibility with Xcode 16 Files and Swift Versions
I'm facing an issue with Swift Playgrounds and files created in Xcode 16. It seems that Swift Playgrounds does not support Swift 6, but even when I create files specifically with Swift 5, Swift Playgrounds still reports that the files are unsupported. This creates a significant problem because macOS Sequoia does not allow me to revert to Xcode 15, which might have offered better compatibility. As it stands, I can't find a solution to work seamlessly between Xcode and Swift Playgrounds. Has anyone else encountered this issue? Are there any workarounds or updates planned to address this compatibility gap? Any advice would be greatly appreciated!

Foundation models not detectable in Xcode simulator
I'm building an app which runs around the Foundation model framework. My expected output is generated when testing on a real device or in preview in Xcode but it throws Foundation Model error when I try running it on the simulator. I'm using a Macbook M1 air and have apple intelligence turned on and my simulator run destination is also an iPad Pro M5 (26.0). Any solution for this as this is my submission for the SSC so I need to make it work on the simulator iPad. Thank you👾

PlaygroundSupport no longer available for Playground apps
In Swift Playground 4.6.2 the package PlaygroundSupport is no longer available to Playground apps. The following test previously permitted apps run in the Playground vs compiled in XCode to support different behavior: #if canImport(PlaygroundSupport) container = NSPersistentContainer(name: "myApp", managedObjectModel: Self.createModel()) #else container = NSPersistentCloudKitContainer(name: "myApp") #endif Since Swift Playground 4.6.2 the PlaygroundSupport package is no longer available for app projects in Playgrounds. Is there a different compile type test which can be used to differentiate compilation for Swift Playground apps ? I am currently having to use a runtime workaround (below) but would prefer a compile time test is an alternative is available. public static var inPlayground: Bool { if Bundle.allBundles.contains(where: { ($0.bundleIdentifier ?? "").contains("swift-playgrounds") }) { return true } else { return false } }

Swift Playground 4.6 - App Fails to Run with import AppIntent
Hi everyone, I’ve been developing an app using Swift Playgrounds, and it was working fine in version 4.5. However, after updating to Swift Playground 4.6, the app no longer runs. After some testing, I found that the issue occurs when import AppIntent is included. Here’s a simple example: import SwiftUI //import AppIntents // <- If this line is included, Preview and Run fail. @main struct MyApp: App { var body: some Scene { WindowGroup { Image(systemName: "globe") .imageScale(.large) .foregroundColor(.accentColor) Text("Hello, world!") } } } Has anyone else encountered this issue? Thanks!

‘Keep going with apps’ Crash during Creature Add steps
Hello fellow Techies! I am currently doing the Swift Playgrounds “Keep Going with Apps” on my iPad Pro. Everything has been going as designed until I got to the ‘Add and Delete Creatures‘ module. The lesson concludes with being able to add a creature to your list in the CreatureZoo. When you run the app from the playground, you can fill out the fields and tap ‘Add’ and that is when the app dims and after 5 seconds I get the notification that the app has an unknown crash. I have reviewed the lessons leading up to it, but I can’t find anything wrong. (Full Disclosure: I really have no clue what I am looking at some of time.) Has anyone else ran into this? `import SwiftUI import Guide struct CreatureEditor: View { //#-learning-code-snippet(defineVariablesCreatureEditor) //#-learning-code-snippet(environmentValue) @State var newCreature : Creature = Creature(name: "", emoji: "") @EnvironmentObject var data : CreatureZoo @Environment(.dismiss) var dismiss var body: some View { SPCAssessableGroup(view: self) { VStack(alignment: .leading) { Form { Section("Name") { //#-learning-code-snippet(addACreatureEditorTextField) TextField("What is your monster's name?", text: $newCreature.name) } Section("Emoji") { TextField("What does your monster look like?", text: $newCreature.emoji) } Section("Creature Preview") { CreatureRow(creature: newCreature) } } } .toolbar { ToolbarItem { Button("Add") { data.creatures.append(newCreature) dismiss() } } } //#-learning-code-snippet(addButtonToToolbar) } } } struct CreatureEditor_Previews: PreviewProvider { static var previews: some View { NavigationStack() { CreatureEditor().environmentObject(CreatureZoo()) } } }’

Piece of code in Playground that reliably crashes lldb server
Dare anyone try the following code in any Playground: // Define a model that conforms to Codable struct User: Codable { var name: String var age: Int var email: String? } // JSON data (as a string for demonstration) let jsonString = """ { "name": "John Doe", "age": 30, "email": "john@example.com" } """ // Convert the JSON string to Data if let jsonData = jsonString.data(using: .utf8) { do { // Parse the JSON data into the User model let user = try JSONDecoder().decode(User.self, from: jsonData) print("Name: \(user.name), Age: \(user.age), Email: \(user.email ?? "N/A")") } catch { print("Error decoding JSON: \(error)") } } I tested with Xcode 16.2 and latest 16.3, it reliably crashes the lldb server!

Swift Playground - Types Lesson
While I am not new to programming, I am quite new to the Swift language. I am using the Swift Playground app on macOS 26 on an M1 MacBook Air. I am on the lesson about types. Perhaps it's a silly question, but what is a portal? It is never described or pointed out where to find it in the puzzle world. Similarly, the instructions reference a "switch" object without ever defining what it is. I cannot write code to call methods or set properties on objects about which I have no useful information. Can anyone advise, please? Thank you kindly.

Initializing Your Expert: turnLockUp() Doesn't Work
I am trying to complete the "Initializing Your Expert" lesson in the Swift Playground. Below I post just a snippet of the code that I wrote, since no matter how many lines of code I write, the turnLock() method has no effect whatsoever. let expert = Expert() /*Create a function that will move the Expert character forward the specified number of tiles. This will make the program easier to code and less verbose. */ func moveExpert(tiles: Int) { for tile in 1...tiles { expert.moveForward() } } /*Create a function to make the Expert do an about face, i.e. orient itself in the opposite direction. */ func aboutFace() { expert.turnRight() expert.turnRight() } expert.turnLockUp() The instructions give no information about this method, such as when or where it can and cannot be called. It states merely that calling it is supposed to "reveal the path between the platforms." I don't see multiple platforms in the 3D puzzle world, just one platform with different levels. No "path between platforms" is ever shown when I call this method, regardless of the location of the Expert character. Why doesn't this method ever do anything at all? Can anyone advise? Thank you kindly.

Help - Can't switch off security warning
Hi, I'm using Swift Playground version 4.6.4 (1997.50) on macOS Tahoe 26.1 and when I create new apps, I get a security warning message every time I try to add a new line of code or switch between ContentView and MyApp source files 🤬 The message is "My app.app would like to access data from other apps" I've checked my Mac's Privacy & Security settings to ensure Playground has full disk access. Clicking the "Allow" button does not resolve the issue, it keeps happening each time I do anything - its makes Playground unusable 😞 Does anyone know how to stop these messages ? Is this a bug ?

Swift Playground preview issues
I am a high school teacher from China, currently teaching programming courses at my school. Several issues are preventing the course from being completed on schedule. As shown in the image, there are two problems: The preview issue has existed since updating to the latest software and system version; I don't know how to resolve it. After renaming a Swift file, this window keeps popping up, even after closing it. This problem didn't exist last year. How can I fix this? Thank you for your reply! 我是一名来自中国的高中教师,目前在学校开设编程课程,目前有几个问题导致课程无法如期完成。如图所示,存在两个问题: 一、自从更新了最新版本的软件和系统后,预览问题就存在,不知该如何处理 二、swift文件重命名后,一直跳出来这个窗口,关掉以后还是跳出来 去年的时候还没有存在这样的问题,请问我该如何处理,感谢您的回复!

Cannot Upload Images on Swift Playground on XCode
Hello! I'm trying to upload images to Swift Playground on XCode, and it's not working. When I created my playground, there is no Resources folder or an assets file. If I simply drag an image file to the sidebar, the image is not showing up when used in the app. This may be a simple fix, but as a beginner, I am struggling to find the solution. Any help would be much appreciated! Thank you!

Query regarding hardware usage for Swift Student Challenge entry
Hello everyone, I am a participant in this year's Swift Student Challenge. My project requires the use of the front-facing camera to detect the user's body movements (supporting connection via iPhone to a Mac or other devices capable of running Xcode/Swift Playgrounds). I would like to ask if this is permitted under the competition rules? Please note that this feature functions entirely offline and does not require an internet connection.
