I’ve encountered a bug in Swift Playgrounds within “Learn to Code 2”, specifically in the “Variables: Seeking Seven Gems” section. No matter what I do—or even if I do nothing at all—an error always occurs.
I’ve tested this on both an iPad (9th generation) and an iPad Pro 11-inch (4th generation), and the issue happens on both devices.
Has anyone else experienced this? Any ideas on how to fix or work around it?
Thanks!

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
}
}

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!
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())
}
}
}’
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!
I clicked the “Get” button in the Swift tutorial, and it started displaying a circular progress bar. However, when the progress bar was full, it did not show that I could use this tutorial, but still display “Get”.
Device: iPad (7th)
System: iPadOS 18.3.2
App Version: 4.6.4
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.
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.

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 ?
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!

Recently, I have experienced this issue and the alert keep popping on my playground non-stop although I pressed "
allow". I have attached the issue screenshot in this post. Can anyone help me with that.
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!

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

I use Swift Playgrounds on iPad to run an intro to programming class with high school students. I've created some custom playground books based on Apple's guides to provide some simple sandboxes to learn basic coding.
Students simply click a button on my website, which downloads my playground books so students can easily create new sandboxes.
With Swift Playgrounds 4.6.1 on both Mac and iPad, clicking the link only opens Swift Playgrounds and does not download my playground books! There used to be an "Add a Subscription URL" button, but it is no longer present on the Learn to Code page or anywhere else in the app that I can find:
Is it intentional that this functionality is removed? Playground Books still appear to work, and documentation for subscription feeds is still available.
I start another session with my students next Monday, so I need to know as soon as possible whether I need to plan to work around this myself.
Thanks,
Mark Schmidt

I'm trying to add Assets.xcassets to a .swiftpm project, but I'm getting the warning:
⚠️ Ignoring duplicate build file in build source build phase
(Just to know, that is about developing in XCODE, in Swift Playgrounds does not appear it, even in this second being harder to setting up)
The problem is that there are no “Build Phases” in XCODE to remove duplicate files manually.
I've already tried adding the path of Assets.xcassets in the resources property of Package.swift, like:
.executableTarget(
name: "AppModule",
path: ".",
resources: [
.process("Assets.xcassets")
]
)
Even so, the warning persists. Does anyone know how to solve this? Is there any way to remove duplicate references or force a cleanup of the Swift Package Manager cache to fix it?
I appreciate any tips! 🙏🚀

In swift playgrounds on my Mac I keep getting this message, “Keep Going with Apps” would like to access data from other apps. I click allow but it the message keeps popping back up.

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.
Just downloaded the latest Swift Playground for Mac (4.6). The Welcome window does not let you scroll horizontally via mouse, trackpad, or other means, so you can only see the first two Learn to Code resources - similar for the App Gallery and Extend Your App sections.
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!
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?
