Swift playgrounds ipad/icloud
Bonjour, a chaque installation de swift playgrounds sur ipad, icloud empeche la sauvegarde et empeche donc d’ouvrir les app. sur icloud drive les fichiers sont present mais a zero ko. par contre les fichiers playgroundsbook fonctionnent. la premiere solution que j’ai ***** etait de desactivé la sauvegarde icloud et ca a fonctionné en local. mais comme je veux mes fichiers sur le icloud drive j’ai tenté une autre approche. j’ai tenté de copié mes fichiers en local sur icloud drive ca ne fonctionne pas. puis j’ai juste fait un drag/drop de fichier app vers le playgrounds. l’app s’ouvre mais n’est pas sauvegardé dans icloud drive. par contre les modifs sont bien enregistrées. enfin j’ai refait la meme approche, une fois l’app ouverte dans playgrounds je l’ai partagé puis enregistré dans icloud. cette fois ci le fichier est pris en compte et fonctionne.

Empty canvas in Swift Playgrounds Mac 15.1
Hi, First post and I am a total newbie when it comes to Ipads & Macs... And also this forum, so sorry if I post in wrong section. My son use Ipad at school and they use Swift Playground there. To be able to do some programming at home, I have set up Vmware with Sequoia 15.1. I installed the app Swift Playground and try to run the playground Get Started with Code and some other education playgrounds. If I understand correctly, it should be some landscape and a figure on the canvas... For me it is only a blue area. I installed XCode, but could not figure out how to run the learning examples there. Tips? Is it possible to run the education playgrounds there? I removed Swift Playgrounds and installed it again, same issue. I also installed IOS 18.1 (?) but I am not sure it is needed. Any suggestion of how I can get contents to show on the canvas? Except of bying an Ipad. ;)

Learn to code 3 missing
Hi Folks! Just started again with playgrounds, and had my "Learn to code 1-2-3" Apps on old versions. Updated 1 and 2 to 5.8, and just found that Learn to code 3 was still on old version (3.1), so decided to delete it. I was hoping that normally I'll just find it where the others are for download (Learn to code & Build Apps), but it is not there.. it is not anywhere, cannot find it, and couldn't find a way to download from anywhere else. Any ideas? Maybe for Learn to code 3 there is no Swift 5.8 yet? Thanks!

Seriously? I can't deploy my demo to iPad cus swift 6?
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!

Swift Student Challenge requires Swift Playground (.swiftpm), minimum OS setting not available.
When making a new Swift Playground via Xcode > New > Project > iOS > App Playground, as a .swiftpm package, the settings are very limited, including setting the minimum OS version. This is incredibly irritating because I can't keep make @available blocks because that would double the size of my code, and I can't use SwiftData (for example) because my app needs to also support iOS 16. Is there a way to set the minimum OS or some other upload type accepted for Apple so that I can change this simple setting? Thank you

LLDB RPC Server Crash Playground File XCode 16.0
When running the code below in a playground file, it crashes with an LLDB RPC Server crash. The crash log is attached. If I put the code into a project, it runs fine. lldb-rpc-server-2024-10-04-110747.txt import Foundation @objc protocol Speaker { func speak() @objc optional func tellJoke() } class Deb: Speaker { func speak() { print("Hello, I'm Deb!") } func tellJoke() { print("What did Sushi A say to Sushi B?") } } class Bryan: Speaker { func speak() { print("Yo, I'm Bryan!") } func tellJoke() { print("What is the object oriented way to become wealthy?") } func writeTutorial() { print("I'm on it!") } } class Animal {} class Dog: Animal, Speaker { func speak() { print("Woof!") } } var speaker: Speaker = Bryan() if speaker is Bryan { print("Hi, I'm a Bryan") } speaker.speak() //speaker.writeTutorial() //won't compile (speaker as!

"public headers ("include") directory path for 'Guide' is invalid or not contained in the target" error
Hi, I have a problem with making a swift playgrounds app walkthrough. I followed the steps exactly and modified my Package.swift a bit (in the targets section): .executableTarget(name: "App", dependencies: ["Guide"], path: "App"),         .target(             name: "Guide",             path: "Guide",             resources: [             .process("Guide.tutorial"),             ]) Now when I open the project in Playgrounds I get this error: public headers ("include") directory path for 'Guide' is invalid or not contained in the target Any help would be appreciated. Thanks

Playgrounds issue: Has to reload the puzzle every time we test code
Hi! I have a remote student who's learning to code in Swift using Playgrounds - Learn to Code 2. It's frustrating to try to test his code when we think he as part of a solution to a puzzle because he can't run his code twice in the same puzzle without resetting the puzzle - when he tries, the page gives an error, and he has to reload the whole puzzle, which erases his code. As a workaround, he's been copying his code and reloading the puzzle whenever he wants to test out a partial solution. Is there an easier way to do this?

Swift Playgrounds BSActionErrorDomain error 1
I am writing an app in Swift Playgrounds 4.5.1 on an iPad 8th generation running iPad OS 17.5.1. When I click the run button I get the error “MyGame Crashed. Update failed. The operation couldn't be completed. (BSActionErrorDomain error 1.) MyGame may have crashed.” It was working up until a few days ago but now it can’t even show the preview. I haven’t updated the app or software since and I can run other app playgrounds. I have multiple nested views with multiple lists of buttons using ForEach statements and I am sharing variables across views using ObservableObject using code like this: class UserProgress: ObservableObject { @Published var score = 0 } struct InnerView: View { @ObservedObject var progress: UserProgress var body: some View { Button("Increase Score") { progress.score += 1 } } } struct ContentView: View { @StateObject var progress = UserProgress() var body: some View { VStack { Text("Your score is \(progress.score)") InnerView(progress: progress) } } }

Get Started with Apps Stuck in Playgrounds
The “Get Started with Apps” in Playgrounds looks great but it won’t allow me to advance to the next activity. It seems to think that my solution is incorrect, but what I did matches the solution provided in the “hint.” This could be corrected by either allowing for more variety in the responses, or by allowing the user to advance to the next activity regardless of whether the response they provided was correct.

How to access this REPL like tool used in a WWDC presentation?
I was watching this presentation about swift. A Swift Tour: Explore Swift’s features and design At timestamp 1:59, the presenter is using what looks sort of like swift playgrounds, however with a feature on the right hand side panel that is sort of like a REPL, and shows the value of an expression. How can I enable this feature? I am on the latest verison of Swift Playgrounds on macOS, and I cannot seem to find it.
