Swift Playgrounds 4.6 removes support for libraries?
I had several library projects that were working in Swift Playgrounds < 4.6 but I get several duplicate compilation errors and previews will not build in Swift Playgrounds > 4.6. Does anyone know how to fix this issue? Example project: This project builds and runs fine under Swift Playgrounds 4.5.1 however it will not run complaining multiple commands produce generated output files under Swift Playgrounds 4.6.1, 4.6.2, and 4.6.3. https://github.com/kudit/Compatibility Download this repository and add the extension ".swiftpm" to the folder and double click to open in Swift Playgrounds. If running on earlier Swift Playgrounds you can see there are no errors and previews work great (on both macOS and iPadOS versions of Swift Playgrounds 4.5.x). However, on Swift Playgrounds 4.6.x, previews will not display. Are embedded libraries not support anymore? This would be very disappointing. I posted this as a Feedback weeks ago with no response: FB16509699

#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```

In "Learning Programming 2", I can't use "world.place"
I'm trying the "Connect and Solve" course of Swift Playground. I can't use "world.place" to place bricks at positions (2, 2), (6, 2) (automatically disappear), but I can place bricks at positions (4, 2) in the same way. Two bricks must be placed overlapping in positions (2, 2) and (6, 2) to achieve the goal. Only when a brick is placed in position (4, 2) can the goal be achieved. The problem is that the bricks placed on (6, 2) and (2, 2) will disappear and cannot be placed successfully. The following is my code writing... let Block1 = Block() for i in 1 ... 2 { world.place(Block1, atColumn: 2, row: 2) } for i in 1 ... 2 { world.place(Block1, atColumn: 6, row: 2) } world.place(Block1, atColumn: 4, row: 2) func turnaround() { turnRight() turnRight() } func walk4() { for i in 1 ... 3 { moveForward() } } func collet() { for i in 1 ... 2 { moveForward() } toggleSwitch() turnRight() walk4() collectGem() turnaround() walk4() turnRight() } for i in 1 ... 3 { collet() } ‌I would appreciate it if someone could offer some recommendations.‌ ‌Thanks a lot‌

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?

Unabled compiler
Hello the community, how are you? Since few days, this messages displays as an error into my code: "The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions" Since all these days, I'm not able to solve this problem. My app is almost done and the code is good. But I don't find where the problem is from. Here's the block where the message appears: var body: some View { //The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions VStack { TextField("Search invoices...", text: $searchText) .padding(10) .background(Color.gray.opacity(0.1)) .cornerRadius(10) .padding(.horizontal) HStack { ForEach(BillFilter.allCases) { filter in Button(action: { selectedFilter = filter }) { Text(filter.rawValue) .padding() .background(selectedFilter == filter ? Color.accentColor : Color.gray.opacity(0.2)) .foregroundColor(selectedFilter == filter ? .white : .black) .cornerRadius(8) } } All the best,

Submitting a Swift Playgrounds app
Certain documentation seems to suggest I can submit a swift playground to the App Store. I am a paid $99 a year developer. In the submission process they ask for my team ID. I am not part of a team. I am an individual. However, my individual account has a team ID associated with it, but they don’t allow me to enter that number in the space provided. There is an * note saying some teams are not permitted to upload to the Apple store connect. How do I, a paid up developer, submit a swift playgrounds app to the App Store?.

Does Swift Playground Support Custom Code Snippets Like Xcode?
While demonstrating Swift Playground to my students, I noticed that, unlike Xcode, it doesn’t seem possible to predefine or insert custom code snippets. In Xcode, we can easily create and reuse our own code snippets to improve teaching and development efficiency, but I couldn’t find a similar feature in Swift Playground. Is there currently a way to predefine or insert custom code snippets in Swift Playground? Are there any recommended workarounds, or plans to support this feature in the future? Any suggestions or insights would be greatly appreciated.

Learn to code / beginner
Hello everyone, I’m completely new to programming and Apple development, but I’ve always had the strong wish to learn coding and to work more deeply with Apple’s system structures. My main questions are: How should I best start learning? For example, is Swift Playgrounds the right first step? How should I continue afterwards to gain further knowledge, possibly in areas like system architecture, cybersecurity, or cloud computing (even though I don’t want to commit too early to one direction)? Can you recommend a learning schedule or intensity (e.g., how often per day or week I should practice) for someone who works full-time? Is my current MacBook Air (2020, Intel i3, 8 GB RAM, 250 GB SSD) still suitable for learning and beginner development, or would you recommend upgrading to a newer model? On top of that, my English is not perfect yet – is it possible to improve it alongside learning coding? I’m very motivated to finally start this journey, even though I once turned down an IBM apprenticeship when I was younger. Now I want to give it a real try. Any advice, personal experiences, or learning resources would be very much appreciated. Thank you in advance!

Suppress “Access Data from Other Apps” Popup in Swift Playgrounds Template on macOS 26
I’m using Swift Playgrounds on macOS 26 to learn app development, starting with the “Get Started with Apps” template. Every time I run the template, macOS shows a popup asking: “Get Started with Apps” wants to access data from other apps. Allow / Don’t Allow I’ve already tried: Granting Playgrounds Full Disk Access in System Settings → Privacy & Security Checking Automation / App Permissions Restarting Playgrounds and macOS …but the popup still appears every run. I’m aware this is related to App Sandbox and privacy restrictions, but I’m looking for a way to: Suppress this popup entirely while running playgrounds code, or Run the template in a way that avoids triggering this permission request. macOS version: 26.1 Playgrounds app version: 4.6.4

Foundation Models support in Swift Playgrounds | SSC26
Hello. I'm building my Swift Student Challenge Project. But I noticed that the FoundationModels Framework isn't supported in Swift Playgrounds. My app uses ARKit, so it definitely should be tested on real device. So, is it possible to somehow implement a foundation models to my Swift Playgrounds app? Or is it possible to ask judges to test the app on real device launching it from xcode. Your answer is really important for because the functionality of my app directly depends on Foundation Models availability. Thank you!

Creating playgrounds from a template does nothing
Attempts to create Swift Playgrounds from the built-in templates fail. Clicking the “Get” button on these templates appears to download something, but it changes back into a “Get” button afterwards without creating a playground. Furthermore, the Swift versions of the templates seem to be behind; it shows Swift 5.8 and Swift 5.9 editions whereas it should be Swift 6.x Steps to Reproduce Start the Swift Playground app (the standalone app, not the Xcode one, on macOS or iPadOS). Select “Learn to Code” Choose the “Get Started With Code” template (or any other template will do). Click the Get button. Wait until the Get button becomes a circular progress indicator. Expected Results A new Swift Playground should be created from the selected template. Actual Results The Get button changes into a circular progress indicator and then changes back. No Playground gets created. Versions Swift Playground 4.7 (2088) macOS 26.4.1 (25E253) iPadOS 26.4.2

Swift Playground cursor moving issue
Moving the cursor left and right becomes extremely sluggish, though up-down movement and mouse clicks are normal. The Apple Store Genius checked the hardware and even reinstalled the OS, but the issue remains.
