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?

How to custom swift playground preview application ($title.app) window size
I used Swift Playground to develop application in Mac OS. Also using ZStack I used limited area in full page (using .frame(width: $, height: $)). However using command + R or clicking start button to see preview .app, while non resizing application my ZStack show as cutted. Please tell me how to set preview .app frame size as width, height... The buttom code is ContentView.swift code. @main struct ContentView: App { init() { MyFont.registerFonts() } // @StateObject private var audioPlayer = AudioPlayer() var body: some Scene { WindowGroup { NavigationStack { StartMenuView() .frame(minWidth: 594, maxWidth: 594, minHeight: 1142, maxHeight: 1142) .preferredColorScheme(.dark) // Dark Mod .statusBar(hidden: true) // Hidden Status Bar .edgesIgnoringSafeArea(.all) // Ignoring Safe Area } } .windowResizability(.contentSize) } } Thank you for reading. ![]("https://developer.apple.com/forums/content/attachment/8ad9f219-6caa-49bf-b8c3-e4b7c91ab40f" "title=image.png;width=1050;height=803") ![]("https://developer.apple.com/forums/content/attachment/395ee85e-9543-4bfd-9caf-3ce3c2ca8414" "title=image2.png;width=1104;height=973")

Making a Screenshot Without Right Hardware
I’m looking to publish an app I’ve written on my iPad (Air, to be exact), but I can’t make a screenshot at the required size (which is Pro). And yes, I don’t have a Mac (yeah, I know). Is there an easy or simple way to get a screenshot of an app if I don’t have the right hardware? Is this something I could scale/resize from a smaller device? Or, could I just include a portion of the actual screenshot in a picture (with the correct dimension) that has other text/information? any help would be greatly appreciated

#Playgrounds conflict duplicate libraries
Experimenting with #Playground macro with Xcode 26 beta 3, out of the box I see a conflict between duplicates in the XcodeDefault Toolchain. Essentially a clean install of macOS Tahoe 26 25A5306g FB18930059 Was trying to follow the first Foundation Model WWDC video example but distilling it down to the most basic use of the Playground macro produces the same error. import Playgrounds #Playground { } Any solutions / workarounds? Wasn't sure whether to attempt to delete one of these–but they are internal libraries. objc[3241]: Class PGLConcurrentMapNode is implemented in both /Applications/Xcode-beta 3.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/Developer/Platforms/MacOSX.platform/Developer/Library/PrivateFrameworks/PlaygroundLogger.framework/Versions/A/PlaygroundLogger (0x10db98c10) and /Applications/Xcode-beta 3.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/libLiveExecutionResultsLogger.dylib (0x10db18050). This may cause spurious casting failures and mysterious crashes. One of the duplicates must be removed or renamed. error: Couldn't look up symbols: protocol descriptor for Playgrounds.__PlaygroundsContentRecordContainer```

ios app products are only permitted in swift playground packages error
Hello all! I am currently facing an issue where I am receiving an "ios app products are only permitted in swift playground packages" error when trying to build the app. I forked a branch from the git repo that my friend made not too long ago, yet I still can't figure out what the issue was. I can provide the repo if needed.

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!

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!

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.

(Swift Playgrounds for Mac) How do I build for iPhone?
I am trying to challenge myself by building an iPhone app in Swift Playgrounds. I just got a Mac Mini M4, so I am trying Swift Playgrounds for Mac. I can submit a build to TestFlight, but it's for Mac and won't let me even test on my iPhone. How can I build my app for iPhone? The least "hacky" answer is appreciated, but I'll entertain anything. Examples in order of hackiness might be: I missed an option in Playgrounds for Mac. Open my playground in Xcode, change something, open back in Playgrounds for Mac. Same as above, but maybe I have to add/copy a file (e.g., manifest.plist). Open my playground in Playgrounds for iPad (I have an iPad 9), do something, copy back to Playgrounds for Mac. Submit via Playgrounds for iPad. Submit via Xcode. BTW, I'm challenging myself not just for its own sake, but because I'm curious how far a student/newbie/etc can take Swift Playgrounds. I was hoping to set a good example for others looking for a lighter-resource, more user-friendly experience than Xcode (which is why I assume Playgrounds for Mac even exists). But right now it feels like Playgrounds for Mac is a … third-class citizen? Maybe the iPad version is second-class? I haven't really tried it. P.S. Why does this text editor seem so lame? Making a numbered list and adding to it is a nightmare. Should be: start a numbered list, hit return, new number appears below. I'm on Safari. This should be the best dev experience on the planet, not the worst!

Playground created on iPad not opening on Mac
I've entered some code on Version 4.5.1 of Playgrounds on my iPad mini running iOS 18.1.1. The file is saved on iCloud and so is available on my Mac running OS 15.2. However, the file will not open in either Playgrounds v 4.5.1 on the Mac (error "Unable to get file wrapper for contents.xcplayground.") or Xcode 16.1 (error "Couldn't load settings from contents.xcplayground"). The file's type is .playgorund. Any thoughts?

Can not use or do anything on the Playgrounds app on iPad Air M2 running iPadOS 18.3 beta
Hi, I have recently downloaded the app to start learning how to code in swift and so on. On my first try I have gotten the error stating that ”.swiftpm files cannot be opened”. I have followed some forum posts. I restarted my iPad several times and redown the app several times. I tried to disable the iCloud sync but I think I deleted the iCloud directory entirely that just results in the app closing on any action taken. (such as pressing the “New App” option or choosing the quick actions to make apps). Is there a way to fix this? Any help is appreciate, please ask me to provide any extra needed information.

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!

Lock Orientation and Disable Multitasking/Slide Over
Hello! I have a quick question about locking orientation and disabling Multitasking/Slide Over in a .swiftpm for the Swift Student Challenge. A .swiftpm file contains a Package.swift file. At the top of this file, there is a very scary warning that directs you to not edit it. However, being unable to edit this means that I cannot lock the orientation of an iPad and disable Multitasking/Slide Over. I have read that it does not break your project if you ignore the warning and I tried it out for myself — editing the file does indeed lock orientation and disable Multitasking/Slide Over! Although, as you can imagine, this is quite nerve-wracking. What are the actual technical implications of doing this? Are participants allowed to do this? If this does not seem like a good idea, would judges follow through with a note that tells them to simply not use certain orientations and Multitasking/Slide Over? (Yeah, I know… not an ideal thing but if there’s anyone to understand it would be Apple employees). I am faced with two uncertain options: ignore a warning and get what I need or follow the warning but then have a very poorly designed experience (some apps just aren’t meant for portrait and Multitasking/Slide Over, even if this is not a full app). I definitely don’t want hundreds of hours of work to go down the drain or risk rejection because of some type of problem with this, that’s for sure. Perhaps a “hack” would work if I were creating an actual app, but the stakes become higher when it is for this challenge. Thanks! :)

Swift playgrounds doesn’t have the IOS 18 SDK
I updated my iPad to iOS 18, but when I went into Swift Playgrounds it only had the iOS 17 SDK. Maybe it has to with the fact that I’m on an iPad 9th Gen and it doesn’t have the Apple intelligence features so it can’t run the AI features. I’m just wondering if I will be getting the new SwiftUI features such as the new TabBar or MeshGradients.
