I really want to participate in the upcoming Swift Student Challenge, but I'm using a MacBook that cannot update past MacOS Big Sur. Would submissions compiled from it still be eligible for SSC? Thank you! :D

Hi everyone, I’m working on my submission for the Swift Student Challenge and need some advice. I already have an existing app that’s live on the App Store, and I’d like to use the same app for my submission. However, while creating the App Playground, I noticed that I’m unable to create additional targets. This is problematic because my app relies heavily on specific targets like ShieldAction, ShieldConfiguration, and DeviceActivityMonitor. Without these targets, the app’s core functionality won’t work as intended. Is there a known limitation or workaround for this? How can I submit my app’s functionality within the constraints of the App Playground? Thanks in advance for your help!

I am currently developing my submission for the SSC and I noticed that the swift playgrounds app for iOS does not have support for the new swift ui features in iOS 18. Are we allowed to submit apps that use these iOS 18 only features?

I’m working on an Xcode App Playground project (.swiftpm) and trying to add a .mlmodel file (e.g., Exercises.mlmodel) to it. However, when I add the .mlmodel file to my project, I encounter the following error: Exercises.mlmodel: No predominant language detected. Set COREML_CODEGEN_LANGUAGE to preferred language. The .mlmodel file works perfectly fine when used in a regular Xcode project (.xcodeproj), but this issue occurs as soon as I add the file in an App Playground project (.swiftpm). Steps I’ve Tried: Ensuring the .mlmodel file is correctly added to the project folder. Checking the generated Core ML Swift code in a .xcodeproj environment—works as expected. Searching for a way to explicitly set COREML_CODEGEN_LANGUAGE in a .swiftpm project, but it seems that Xcode does not provide this option. Any advice or solutions would be greatly appreciated! I have tried the solutions in these articles, however none of them worked: https://medium.com/@sofiadinizms/how-to-use-coreml-in-swift-playgrounds-8d5f001c5d15 https://developer.apple.com/forums/thread/743942?answerId=776359022#776359022

I am trying to implement a ML model with Core ML in a playground for a Student Challenge project, but I can not get it to work. I have already tried everything I found online but nothing seems to work (the tutorials where posted long time ago). Anyone knows how to do this with Xcode 15 and the most recent updates?

I’m working in the app playground and want to add my usdz file but when i drag drop the file to my main folder i cannot add target to it which leads to a resource not found error while I build my app. It was working on a normal xcode project but while transitioning to app playground it is not working. How can I fix this issue?

This is my code in ContentView: import SwiftUI import SceneKit import PlaygroundSupport struct ContentView: View { var body: some View { VStack { Text("SceneKit with SwiftUI") .font(.headline) .padding() SceneView( scene: loadScene(), options: [.autoenablesDefaultLighting, .allowsCameraControl] ) .frame(width: 400, height: 400) .border(Color.gray, width: 1) } } } func loadScene() -> SCNScene? { if let fileURL = Bundle.main.url(forResource: "a", withExtension: "dae") { do { let scene = try SCNScene(url: fileURL, options: [ SCNSceneSource.LoadingOption.checkConsistency: true ]) print("Scene loaded successfully.") return scene } catch { print("Error loading scene: \(error.localizedDescription)") } } else { print("Error: Unable to locate a.dae in Resources.") } return nil } a.dae file exists in the Resources section of macOS Playground app. And a.dae can be viewed in Xcode. Console shows: Error loading scene: The operation couldn’t be completed. (Foundation._GenericObjCError error 0.) Any input is appreciated.

As predictive code completion is natively included in Xcode, are we allowed to use it for the Swift Student Challenge?

Hey, If I were a PhD student enrolled at an accredited academic institution, would I still be eligible to participate in the Swift Student Challenge? Thank you!

I can't seem to access preview for any of my views in any of my swift projects at all (using Mac to code and using iPhone 16 pro as preview and simulation, simulation can work), even after restarting Mac and Xcode itself. The preview section has a popup saying "Cannot preview in this file, unexpected error occured" (for every file), please tell me what is wrong and help me solve it to see the preview, thank you! details

Desarrolle una app en xcode 16 para version minima de ios 16, todo funcionaba bien hasta la version 17 de ios, pero para ios 18 empezaron los problemas, los botones no responden a un toque, se deben sostener con un toque largo para que funcionen, ahora de un momento a otro ya no funciona para ninguna version de ios, los eventos tactiles deben ser prolongados para que se activen, en los botones o elementos que usan el tapgesture, he probado de todo versiones de xcode, versiones de swiftui, dispostivos reales, emuladores de todo y nada funciona, algun consejo o solucion gracias

I am getting issue on my application that my device is jailbroken security message I updated my device 18.2 what the solution

I want to use Swift language to write code for drawing multiple polygons. I would like to find some examples as references. Can anyone provide example code or tell me where I can see such examples? Thank you!

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

Following the examples from the official documentation: https://developer.apple.com/documentation/swiftui/adding-a-search-interface-to-your-app When the user types in the text in the search field, the list is updated with filtered results. How do I cause these changes to be animated? I tired to put .animated() after the .searchable modifier, the result was what I am looking for, however it also broke the animation of the search field getting/releasing focus.

Hello, Developer team! Does anyone have an idea about the problem I'm facing with the simulator ? I'm learning how to code in SwiftUI and my simulator was working just fine but yesterday I close my laptop the other day and open today and see the code : import SwiftUI import SwiftData @main struct first_projectApp: App { var sharedModelContainer: ModelContainer = { let schema = Schema([ Item.self, ]) let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false) do { return try ModelContainer(for: schema, configurations: [modelConfiguration]) } catch { fatalError("Could not create ModelContainer: \(error)") } }() var body: some Scene { WindowGroup { ContentView() } .modelContainer(sharedModelContainer) } } I don't know where it comes from . I used IOS 17.5 I try to upgrade to IOS 18 but that didn't fix the problem. Currently I'm seeing 3 errors : Showing Recent Errors Only Build target first project of project first project with configuration Debug Ld /Users/amedekatamatode/Library/Developer/Xcode/DerivedData/first_project-ebsglpjmgwtgzpflkvloohzydjuf/Build/Products/Debug-iphonesimulator/first\ project.app/first\ project.debug.dylib normal (in target 'first project' from project 'first project') cd /Users/amedekatamatode/Desktop/calculator/first\ project /Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang -Xlinker -reproducible -target arm64-apple-ios17.5-simulator -dynamiclib -isysroot /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator18.0.sdk -O0 -L/Users/amedekatamatode/Library/Developer/Xcode/DerivedData/first_project-ebsglpjmgwtgzpflkvloohzydjuf/Build/Intermediates.noindex/EagerLinkingTBDs/Debug-iphonesimulator -L/Users/amedekatamatode/Library/Developer/Xcode/DerivedData/first_project-ebsglpjmgwtgzpflkvloohzydjuf/Build/Products/Debug-iphonesimulator -F/Users/amedekatamatode/Library/Developer/Xcode/DerivedData/first_project-ebsglpjmgwtgzpflkvloohzydjuf/Build/Intermediates.noindex/EagerLinkingTBDs/Debug-iphonesimulator -F/Users/amedekatamatode/Library/Developer/Xcode/DerivedData/first_project-ebsglpjmgwtgzpflkvloohzydjuf/Build/Products/Debug-iphonesimulator -filelist /Users/amedekatamatode/Library/Developer/Xcode/DerivedData/first_project-ebsglpjmgwtgzpflkvloohzydjuf/Build/Intermediates.noindex/first\ project.build/Debug-iphonesimulator/first\ project.build/Objects-normal/arm64/first\ project.LinkFileList -install_name @rpath/first\ project.debug.dylib -Xlinker -rpath -Xlinker @executable_path/Frameworks -dead_strip -Xlinker -object_path_lto -Xlinker /Users/amedekatamatode/Library/Developer/Xcode/DerivedData/first_project-ebsglpjmgwtgzpflkvloohzydjuf/Build/Intermediates.noindex/first\ project.build/Debug-iphonesimulator/first\ project.build/Objects-normal/arm64/first\ project_lto.o -Xlinker -export_dynamic -Xlinker -no_deduplicate -Xlinker -objc_abi_version -Xlinker 2 -Xlinker -debug_variant -fobjc-link-runtime -fprofile-instr-generate -L/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphonesimulator -L/usr/lib/swift -Xlinker -add_ast_path -Xlinker /Users/amedekatamatode/Library/Developer/Xcode/DerivedData/first_project-ebsglpjmgwtgzpflkvloohzydjuf/Build/Intermediates.noindex/first\ project.build/Debug-iphonesimulator/first\ project.build/Objects-normal/arm64/first_project.swiftmodule -Xlinker -alias -Xlinker _main -Xlinker ___debug_main_executable_dylib_entry_point -Xlinker -no_adhoc_codesign -Xlinker -dependency_info -Xlinker /Users/amedekatamatode/Library/Developer/Xcode/DerivedData/first_project-ebsglpjmgwtgzpflkvloohzydjuf/Build/Intermediates.noindex/first\ project.build/Debug-iphonesimulator/first\ project.build/Objects-normal/arm64/first\ project_dependency_info.dat -o /Users/amedekatamatode/Library/Developer/Xcode/DerivedData/first_project-ebsglpjmgwtgzpflkvloohzydjuf/Build/Products/Debug-iphonesimulator/first\ project.app/first\ project.debug.dylib ld: warning: Could not parse or use implicit file '/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/Frameworks/SwiftUICore.framework/SwiftUICore.tbd': cannot link directly with 'SwiftUICore' because product being built is not an allowed client of it Undefined symbols for architecture arm64: "_main", referenced from: ___debug_main_executable_dylib_entry_point in command-line-aliases-file ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation) Undefined symbol: _main Linker command failed with exit code 1 (use -v to see invocation) I hope someone helps me how to figure it out.

Hello, Although the Swift Student Challenge for 2025 has not yet been announced and is not officially taking place, I have a question regarding last year’s rules in the Swift Student Challenge. This is, of course, assuming the rules will be similar if the challenge runs again next year. I am interested in utilizing CreateML to design a text classifier model. Given the substantial amount of data required for machine learning, am I allowed to outsource data from open-source libraries and/or social media platforms, provided that these resources abide by their terms of service? My primary concern is if I must create my own data as that will be time-consuming and more biased. Thank you, Jesse

I have an app which have an Immersive Space view and it needs the user to have a button in the bottom which have a fixed place in front of the user head like a dashboard in game or so but when the user get too close to any3d object in the view it could cover the button and make it inaccessible and it mainly would prevent the app for being approved like that in appstoreconnect I was working before on SceneKit and there was something like camera view Znear and Zfar which decide when to hide the 3d model if it comes too close or gets too far and I wonder if there is something like that in realityView / RealityKit 4. Here is My Code and the screenshots follows import SwiftUI import RealityKit struct ContentView: View { @State var myHead: Entity = { let headAnchor = AnchorEntity(.head) headAnchor.position = [-0.02, -0.023, -0.24] return headAnchor }() @State var clicked = false var body: some View { RealityView { content, attachments in // create a 3d box let mainBox = ModelEntity(mesh: .generateBox(size: [0.1, 0.1, 0.1])) mainBox.position = [0, 1.6, -0.3] content.add(mainBox) content.add(myHead) guard let attachmentEntity = attachments.entity(for: "Dashboard") else {return} myHead.addChild(attachmentEntity) } attachments: { // SwiftUI Inside Immersivre View Attachment(id: "Dashboard") { VStack { Spacer() .frame(height: 300) Button(action: { goClicked() }) { Text(clicked ? "⏸️" : "▶️") .frame(maxWidth: 48, maxHeight: 48, alignment: .center) .font(.extraLargeTitle) } .buttonStyle(.plain) } } } } func goClicked() { clicked.toggle() } }

All errors in TranslationError return the same error code, making it difficult to differentiate between them. How can this issue be resolved?

Hi everyone, We have a user experiencing a display issue. Here's a screenshot they shared with us. Unlike in the simulator, where we see three icons, their display shows two buttons abbreviated with ellipses. The device is iPhone 12 mini with iOS 17.6.1. The user isn't using any accessibility settings or large text size. Does anyone know what setting might be causing this? Any advice would be appreciated! Thanks!
