Create Mac App from Swift Playgrounds
I am running Swift Playgrounds 4.51 under OSX 14.7 on a Mac mini M2 Pro. Under App settings for my app, I select "Install on this Mac." I get an error "An error occurred during installation Please check Console.app for further information" I can't find any entry in the console logs for this. I have a personal (free) developer account. Is there a way to create a Finder launchable app with Swift Playgrounds? I found part of the problem. My main user that I use for "normal" activity does not have administrative rights. If I give that user administrative rights, the create app succeeds and the app is added to the global Applications folder. Is there a way to have the app added to my User Application folder that then shouldn't require administrative access?

Swift Playground does not detect errors in some conditions
Thanks for the upgrade, the new project selection screen is nice and I’m happy that the SDK has been updated. But I notices some issues Since update to 4.6 In an app project, if one of the file contains an error and I select another file. The error is not reported and the upper icon shows a checked mark as if the project contains no compilation errors. Also, if I’m on the file that contains the error the upper icon turn in red (that is ok) but if I press the icon then the error message, the editor does not jump to the error It was working fine on the previous version (I use it on a iPad pro (A12Z) with the latest iPad OS version)

Swift Playgrounds 4.6.1 Removes Subscription Feeds
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

Swift Playgrounds on iPad localization
Hey, meanwhile it's a great thing to program apps on the iPad and to be able to load them into the App Store Connect and the App Store. What about localization in the meantime? When I open the folder en.lproj in sample apps from XCode, then there are two files stored in it: Glossary.plist (XML) and Localizable.strings (binary) Is it correct that XCode creates binary files from the strings? Otherwise, Swift Playgrounds already offers localization in the localized learning content, but i guess the binary files can only be created in XCode?

Fatal Error in Swift Playground
Fatal Error in Swift Playground Description I'm experiencing a catastrophic error when importing Package Dependency in any Swift Playgrounds that has icon or name that caused the whole Playground won't work anymore with error messages below. I'm current running macOS Sequoia 15.3 (24D60) and Swift Playgrounds 4.6.1. They're all up-to-date. Reproduction Open Swift Playgrounds and and create a new project. Import a package dependency https://github.com/simibac/ConfettiSwiftUI.git Rename the project and add an icon Then you should able the reproduce the problem. I strongly believed that this is a serious bug. You'll find that Assets in the left column are disappeared and appeared Assets.xcassets, you're unable to reveal the Dependency in the column like the reference picture above. The whole Playground is destroyed now and unable to work anymore.

Metal Integration with SwiftUI
Hello! I have asked this question in previous years, but I want to make sure I can be safe as each challenge could be different. Are applicants for the Swift Student Challenge allowed to use the features and technologies involved with Metal/MetalKit? Last year, the answer was yes. I have seen a few people here and there use it with Swift and won. I would like to know if we can use it for the 2025 challenge for this year as well. Thanks! :)

Xcode: Skipping Duplicate Build File in Compile Sources in a .swiftpm Project – How to Fix?
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! 🙏🚀

Swift Playground 4.6 - App Fails to Run with import AppIntent
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!

How to add a macOS dock icon from Sketch into Swift Playground?
Hi, friends! I have a Keynote file, in which I create design for macOS applications settings and system settings, that I use and which are installed on my Mac. I like to record my settings so that every time I reinstall the system or an application I can open my file and set it up exactly the way I want. It's like a user manual, only it looks nice with Mac design elements. And I do it in a presentation (Keynote). I also use a Sketch for the design. I want to turn all this into an app for myself, using Swift Playground. Does anyone know how to, for example, add a macOS Dock icon from a Sketch to Swift Playground?

Initializing Your Expert: turnLockUp() Doesn't Work
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.

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.

"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?
