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```

(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.

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.
