I clicked the “Get” button in the Swift tutorial, and it started displaying a circular progress bar. However, when the progress bar was full, it did not show that I could use this tutorial, but still display “Get”. Device: iPad (7th) System: iPadOS 18.3.2 App Version: 4.6.4

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!

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.

Hello I'm getting this error in my code and I don't know why. Can somebody explain this or point me at a help article. import UIKit var greeting = "Hello, playground" let imageView = UIImageView() imageView.image = UIImage(named: "image") Utils.getImageSize(view: imageView) class Utils { static func getImageSize(view imageView: UIImageView) { let image = imageView.image print("Image size = \(image?.size ?? CGSize.zero)") } } The error is as follows: Cheers Murray

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```

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

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?.

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?

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,

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'?

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!

Dare anyone try the following code in any Playground: // Define a model that conforms to Codable struct User: Codable { var name: String var age: Int var email: String? } // JSON data (as a string for demonstration) let jsonString = """ { "name": "John Doe", "age": 30, "email": "john@example.com" } """ // Convert the JSON string to Data if let jsonData = jsonString.data(using: .utf8) { do { // Parse the JSON data into the User model let user = try JSONDecoder().decode(User.self, from: jsonData) print("Name: \(user.name), Age: \(user.age), Email: \(user.email ?? "N/A")") } catch { print("Error decoding JSON: \(error)") } } I tested with Xcode 16.2 and latest 16.3, it reliably crashes the lldb server!

第一次接触swift编程，swift playground里面编程入门挺简单的，因为英语也不好，不知道怎么入手了

Hello fellow Techies! I am currently doing the Swift Playgrounds “Keep Going with Apps” on my iPad Pro. Everything has been going as designed until I got to the ‘Add and Delete Creatures‘ module. The lesson concludes with being able to add a creature to your list in the CreatureZoo. When you run the app from the playground, you can fill out the fields and tap ‘Add’ and that is when the app dims and after 5 seconds I get the notification that the app has an unknown crash. I have reviewed the lessons leading up to it, but I can’t find anything wrong. (Full Disclosure: I really have no clue what I am looking at some of time.) Has anyone else ran into this? `import SwiftUI import Guide struct CreatureEditor: View { //#-learning-code-snippet(defineVariablesCreatureEditor) //#-learning-code-snippet(environmentValue) @State var newCreature : Creature = Creature(name: "", emoji: "") @EnvironmentObject var data : CreatureZoo @Environment(.dismiss) var dismiss var body: some View { SPCAssessableGroup(view: self) { VStack(alignment: .leading) { Form { Section("Name") { //#-learning-code-snippet(addACreatureEditorTextField) TextField("What is your monster's name?", text: $newCreature.name) } Section("Emoji") { TextField("What does your monster look like?", text: $newCreature.emoji) } Section("Creature Preview") { CreatureRow(creature: newCreature) } } } .toolbar { ToolbarItem { Button("Add") { data.creatures.append(newCreature) dismiss() } } } //#-learning-code-snippet(addButtonToToolbar) } } } struct CreatureEditor_Previews: PreviewProvider { static var previews: some View { NavigationStack() { CreatureEditor().environmentObject(CreatureZoo()) } } }’

After updating playgroud to the latest 4.6.3 version, the original sample app download interface disappeared. I tried many methods but couldn't find it again. How should I retrieve it again? Or was it deleted in this version?

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!

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

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

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 } }
