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!

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 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.

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

Unable to rename the Swift Playground or add an icon when package dependencies is imported
I'm unable to rename my Swift Playground or add/change the app icon when I imported a package dependency after upgraded my Swift Playgrounds App to the newest version. Every time I tried to do that, the whole project will be destroyed and showed error message below. I wonder if anyone have same experience with me or someone can tell me the solution, it terrifies me and I'm worried that I'll be unable to submit my project on time because of that.

Swift Playgrounds 4.6 removes support for libraries?
I had several library projects that were working in Swift Playgrounds < 4.6 but I get several duplicate compilation errors and previews will not build in Swift Playgrounds > 4.6. Does anyone know how to fix this issue? Example project: This project builds and runs fine under Swift Playgrounds 4.5.1 however it will not run complaining multiple commands produce generated output files under Swift Playgrounds 4.6.1, 4.6.2, and 4.6.3. https://github.com/kudit/Compatibility Download this repository and add the extension ".swiftpm" to the folder and double click to open in Swift Playgrounds. If running on earlier Swift Playgrounds you can see there are no errors and previews work great (on both macOS and iPadOS versions of Swift Playgrounds 4.5.x). However, on Swift Playgrounds 4.6.x, previews will not display. Are embedded libraries not support anymore? This would be very disappointing. I posted this as a Feedback weeks ago with no response: FB16509699

‘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()) } } }’

Learn to code / beginner
Hello everyone, I’m completely new to programming and Apple development, but I’ve always had the strong wish to learn coding and to work more deeply with Apple’s system structures. My main questions are: How should I best start learning? For example, is Swift Playgrounds the right first step? How should I continue afterwards to gain further knowledge, possibly in areas like system architecture, cybersecurity, or cloud computing (even though I don’t want to commit too early to one direction)? Can you recommend a learning schedule or intensity (e.g., how often per day or week I should practice) for someone who works full-time? Is my current MacBook Air (2020, Intel i3, 8 GB RAM, 250 GB SSD) still suitable for learning and beginner development, or would you recommend upgrading to a newer model? On top of that, my English is not perfect yet – is it possible to improve it alongside learning coding? I’m very motivated to finally start this journey, even though I once turned down an IBM apprenticeship when I was younger. Now I want to give it a real try. Any advice, personal experiences, or learning resources would be very much appreciated. Thank you in advance!

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 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!

“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.

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!

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 :)
