Swift Student Challenge – Using iOS 26 APIs + Camera Input in Xcode App Playgrounds (Simulator Limitation)
Hi, I’m working on my Swift Student Challenge submission using iOS 26 APIs (FoundationModels) along with AVFoundation + Vision to capture user input and generate feedback. Since Swift Playgrounds doesn’t support FoundationModels framework, I’m using an Xcode App Playground, but I heared that submissions are reviewed in the Simulator, which doesn’t support live camera feed. I’m unsure how to handle this. Looking for guidance on the recommended approach. Thanks!

SwiftUI iOS 26 .safeAreaBar issue with large navigation title
I have some really straight forward code in a sample project. For some reason when the app launches the title is blurred obscured by scrolledgeeffect blur. If I scroll down the title goes small as it should do and all looks fine. If I scroll back to the top, just before it reaches the top the title goes large and it looks correct, but once it actually reaches/snaps to the top, is then incorrectly blurs again. Is there anything obvious I'm doing wrong? Is this a bug? struct ContentView: View { var body: some View { NavigationStack { ScrollView { VStack { Rectangle().fill(Color.red.opacity(0.2)).frame(height: 200) Rectangle().frame(height: 200) Rectangle().frame(height: 200) Rectangle().frame(height: 200) Rectangle().frame(height: 200) } } .safeAreaBar(edge: .top) { Text("Test") } .navigationTitle(Title") } } }

Swift Student Challenge Questions
Hey there! I have a few questions about the Swift Student Challenge: Is it acceptable to include placeholders for features that aren’t supported by Swift Playgrounds, or features I planned but didn’t have time to fully implement (as long as the core experience works)? My app relies a lot on user inputs. Is it okay to include a button that loads sample data for reviewers, or is there a preferred approach for this? Besides the known constraints (< 25 MB, experienceable within ~3 minutes), are there any other limits, e.g. lines of code or overall app complexity Can AI-generated assets (e.g. images) be used if they’re clearly labeled as such inside the app? Do we need to explicitly document where AI was used (assets, code, etc.) as part of the submission? My app uses the Foundation Model: On what device is the submission evaluated and should the usage of the Foundation Model be explicitly marked for reviewers? Thanks a lot, and sorry for the many questions!

Is it safe to manually edit Package.swift (iOS Version & Orientation) for SSC 2026?
Hi everyone, I am working on my submission for the Swift Student Challenge 2026 using a Swift App Playground (.swiftpm). The default project was set to iOS 16, but I manually edited the Package.swift file to change the minimum version to iOS 18.0 so I can use the latest APIs. I also modified the supportedInterfaceOrientations to lock the app to Portrait mode only. I know the file contains a warning saying "Do not edit it by hand," so I am worried about two things: Disqualification: Will manually changing the iOS version from the default 16.0 to 18.0 cause any issues with the submission validator or the judging environment? Orientation: Is it acceptable to strictly force .portrait mode for the challenge, or are we required to support landscape/responsive layouts for the judges' iPads? I want to make sure these manual changes won't technically invalidate my playground. Thanks for your help!

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!

Xcode Playgrounds crashes upon microphone access
Sorry if this is a dumb question. I’m still a beginner. I created an Xcode Playground app with Microphone and Speech Recognition capabilities enabled, along with a backup Info.plist. However, when running the app on Mac Catalyst, a real device, or the iOS and iPadOS simulators, it crashes right after the Speech Recognition permission popup and again after the Microphone permission popup. For extra context, the app initially worked fine in the Swift Playgrounds app, but that environment uses an outdated SDK, so it no longer supports some of the features I’ve implemented. I’m also struggling to find clear, beginner-friendly documentation that explains how AVAudioEngine works, which is making it hard to understand what’s going wrong and how to debug it.

Swift Playground Assets missing??
I’m seeing what looks like a change or possible bug in Xcode when creating a new Swift Playground. When I create a Swift Playground using Xcode (File → New → Playground), the project is generated without an Assets folder. I’ve reproduced this multiple times with fresh Playgrounds to rule out user error and the folder is consistently missing. Previously, new Playgrounds included an Assets catalog by default, which makes this behavior surprising.

Metal not working in Swift Playgrounds (SSC Scene)
Hi everyone, I'm currently working on a Swift Playgrounds project where I need to incorporate a Metal shader file. However, when I tried to include my shader file (PincushionShader.metal), I encountered the following error: Is it possible to use Metal shader files within Swift Playgrounds, it is really important for my swift student challenge scene? If not, are there any workarounds or recommended approaches for testing Metal shaders in a similar environment? Any guidance or suggestions would be greatly appreciated!

IPad OS 16.1, Playgrounds and input fields
I have installed the latest beta on my iPad , iPadOS 16.1 (20B5050f) On running in app in Playgrounds that has a TextField, external keyboard input do not seem to be working. Tapping on the Text field inserts the cursor but no text can be entered on my external keyboard. (TextEditor field also do not work) Tested with both a Smart Keyboard and a Magic Keyboard. The keyboard works to enter the code in playgrounds, so it is not a keyboard connection issue. Disconnecting the keyboard, the onscreen keyboard is displayed and works correctly. Is this a Playgrounds issue or an iPadOS 16.1 issue or a compatibility issue with Playgrounds & iPadOS 16.1 ? import SwiftUI struct ContentView: View {     @State var field: String = "Test input"          var body: some View {         VStack {             Image(systemName: "globe")                 .imageScale(.large)                 .foregroundColor(.accentColor)             Text("Hello, world!")             TextField("", text: $field)                 .frame(height: 100)         }     } }

Can I Use Xcode and iPadOS 18? (and RealityView)
I'm preparing my submission for the Swift Student Challenge, and I have a couple of questions regarding the development environment. Is it allowed to use Xcode to program my scene, or do I have to use Swift Playgrounds? Can I use iPadOS 18 for development? I noticed that Swift Playgrounds currently only supports up to iPadOS 17.5, but I would like to use RealityView, which is only available starting from iPadOS 18. I appreciate any clarification on this. Thanks in advance!

Locking App Orientation to Landscape in Playground
Hello! I’m building my Swift Student Challenge project in Swift Playgrounds, and I’ve run into an issue with app orientation. Since this is a game, the layout and interactions only work correctly in landscape, but Playgrounds doesn’t offer the usual orientation settings you’d configure in Xcode. Is there a recommended way to force a landscape-only experience in Swift Playgrounds using SwiftUI? Any workarounds or guidance would be greatly appreciated! Thank you!

Swift Playground preview issues
I am a high school teacher from China, currently teaching programming courses at my school. Several issues are preventing the course from being completed on schedule. As shown in the image, there are two problems: The preview issue has existed since updating to the latest software and system version; I don't know how to resolve it. After renaming a Swift file, this window keeps popping up, even after closing it. This problem didn't exist last year. How can I fix this? Thank you for your reply! 我是一名来自中国的高中教师,目前在学校开设编程课程,目前有几个问题导致课程无法如期完成。如图所示,存在两个问题: 一、自从更新了最新版本的软件和系统后,预览问题就存在,不知该如何处理 二、swift文件重命名后,一直跳出来这个窗口,关掉以后还是跳出来 去年的时候还没有存在这样的问题,请问我该如何处理,感谢您的回复!

Help - Can't switch off security warning
Hi, I'm using Swift Playground version 4.6.4 (1997.50) on macOS Tahoe 26.1 and when I create new apps, I get a security warning message every time I try to add a new line of code or switch between ContentView and MyApp source files 🤬 The message is "My app.app would like to access data from other apps" I've checked my Mac's Privacy & Security settings to ensure Playground has full disk access. Clicking the "Allow" button does not resolve the issue, it keeps happening each time I do anything - its makes Playground unusable 😞 Does anyone know how to stop these messages ? Is this a bug ?

Core Data stack in #Playground
I'm using the #Playground macro in Xcode 26.0, running on macOS 26.0. I can get the basics working, but I don't understand how it hooks into the rest of the app, like the App Delete or the Core Data stack. Do we have to create a new Core Data stack, like for SwiftUI Previews, or can it hook into the stack from the main app (if so, how)?
