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!

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.

Okay everyone who click into or just pass by this post ,to cut a farrrirly
long story short ,here is the thing...
I was devloping my app in the playground on my Mac , which was building for the iPad, In the early time of real machine commissioning(through the Xcode ),everything is okay everything is okay..
"well,mabe it's time to deploy my app to the playground in ipad"! Then,to top it all off🤣,then playground tell me
(In case that you can't understand chinese and creat ambiguity )
emm that's too tight...,so I can only got back to the Xcode changing my language version to swift 5
then.....
Noting change ....
and
I think err.. in order to properly deploy app to iPad
,I had to rework my code with swift 5!
So, I almost fell on my knees ,can somebody who in charge of the playground ,can somebody who in charge of the playground ,just ,just! shove swift 6 in the playground (as long as it make my code run anyway),
otherwise there's no way to debug it!
please please plase!

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! 🙏🚀

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.
