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```

Cannot Upload Images on Swift Playground on XCode
Hello! I'm trying to upload images to Swift Playground on XCode, and it's not working. When I created my playground, there is no Resources folder or an assets file. If I simply drag an image file to the sidebar, the image is not showing up when used in the app. This may be a simple fix, but as a beginner, I am struggling to find the solution. Any help would be much appreciated! Thank you!

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'?
