Save Data from Swift Playgrounds App (Mac)
How do you save data from a Swift Playgrounds App on the Mac? I get an error 'playgroundSharedDataDirectory is not supported in Swift Playgrounds' I think it's doable, some of the Swift Playgrounds tutorials remember the pages I've completed. This is with Playgrounds 4.5.1 on a Mac mini M2 Pro running OSX 14.7 (Sonoma) Ideally, I'd like to save multiple 'documents' and allow the user to select which one they want to work with. The documents don't need to be visible to other Apps. Thanks in advance

Swift Playground New File & Folder Not Able to Rename
Hi, I encountered an issue after the latest update on Swift Playground. I’m using the iPad Pro 3rd Gen, first time reporting a bug hopefully I’m on the right platform. When I create a new Swift file or folder, it’ll auto revert the file/folder name to the default naming upon creation. Tested this one on a few existing projects, it’s the same for all of them. Initially when I created a new project to verify, those files/folders can be renamed without the issue of reverting. But after testing it again, seems like the same issue is happening to it as well. I‘ve tried restarting my iPad but the problem persists. So I thought to report it and from my search seems like this is the platform for it? Thanks.

Bug in ‘Learn to Code 2’ – ‘Variables: Seeking Seven Gems’ Causing Errors Regardless of Actions
I’ve encountered a bug in Swift Playgrounds within “Learn to Code 2”, specifically in the “Variables: Seeking Seven Gems” section. No matter what I do—or even if I do nothing at all—an error always occurs. I’ve tested this on both an iPad (9th generation) and an iPad Pro 11-inch (4th generation), and the issue happens on both devices. Has anyone else experienced this? Any ideas on how to fix or work around it? Thanks!

PlaygroundSupport no longer available for Playground apps
In Swift Playground 4.6.2 the package PlaygroundSupport is no longer available to Playground apps. The following test previously permitted apps run in the Playground vs compiled in XCode to support different behavior: #if canImport(PlaygroundSupport) container = NSPersistentContainer(name: "myApp", managedObjectModel: Self.createModel()) #else container = NSPersistentCloudKitContainer(name: "myApp") #endif Since Swift Playground 4.6.2 the PlaygroundSupport package is no longer available for app projects in Playgrounds. Is there a different compile type test which can be used to differentiate compilation for Swift Playground apps ? I am currently having to use a runtime workaround (below) but would prefer a compile time test is an alternative is available. public static var inPlayground: Bool { if Bundle.allBundles.contains(where: { ($0.bundleIdentifier ?? "").contains("swift-playgrounds") }) { return true } else { return false } }

Playgrounds not able to be built on iPad
I developed my app on xcode, and it builds fine for xcode on simulator. However, when I transferred the swiftpm file to my ipad, the playground failed to build with only the error message "Build failed", while preview on playgrounds works fine. I am not sure what the cause of the error is, if anyone has any tips that would be greatly appreciated. Thank you.

How to install codes from Playground on iPhone
Hi there, I'm currently learning how to write some code using Swift Playgrounds on my Mac, and I'm wondering if there's a way to install the code I create onto my iPhone, like a regular app. I've searched online quite a bit but haven't found any clear or definitive answers. Many resources mention a "Run on iPhone" option in Swift Playgrounds, but I don't see that button in my version. I even installed Xcode and connected my iPhone to my Mac, following the instructions I found, but the "Run on iPhone" option still doesn't appear in Playgrounds. I've updated my Mac, iPhone, and Playgrounds to the latest version. Thank you for your help!

no option for "Extended Runtime Session"
How can I enable "Extended Runtime Sessions" for a companion watch app? Here https://developer.apple.com/documentation/watchkit/using-extended-runtime-sessions in targets under 'Signing & Capabilities' I checked "Audio" and Session Type 'Mindfulness', I created an ExtendedRuntimeManager.swift file. When running a simulation the error message says "Extended Runtime Session ungültig: Reason=-1, Error=This application does not have appropriate permissions to schedule a session." How does the app get the 'appropriate permissions'?

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.

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

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. ;)
