can i use AI scanning phone camera in WWDC Swift student challenge ?

How do I add a already made CoreML model into my playground? I tried what people recommended online -- building a test project and get the .mlmodelc file and put that in the playground along with the autogenerated class for the model. However, I keep on getting so many errors. The errors: Unexpected duplicate tasks Target 'help' (project 'help') has write command with output /Users/cpulipaka/Library/Developer/Xcode/DerivedData/help-appuguzbduqvojfwkaxtnqkozecv/Build/Intermediates.noindex/Previews/help/Intermediates.noindex/help.build/Debug-iphonesimulator/help.build/adc7818afdf4ae03fd98cdd618954541.sb Target 'help' (project 'help') has write command with output /Users/cpulipaka/Library/Developer/Xcode/DerivedData/help-appuguzbduqvojfwkaxtnqkozecv/Build/Intermediates.noindex/Previews/help/Intermediates.noindex/help.build/Debug-iphonesimulator/help.build/adc7818afdf4ae03fd98cdd618954541.sb Unexpected duplicate tasks Showing Recent Issues Target 'help' (project 'help'): CoreMLModelCompile /Users/cpulipaka/Library/Developer/Xcode/DerivedData/help-appuguzbduqvojfwkaxtnqkozecv/Build/Intermediates.noindex/Previews/help/Products/Debug-iphonesimulator/help.app/ /Users/cpulipaka/Desktop/help.swiftpm/Resources/ZooClassifier.mlmodel Target 'help' (project 'help'): CoreMLModelCompile /Users/cpulipaka/Library/Developer/Xcode/DerivedData/help-appuguzbduqvojfwkaxtnqkozecv/Build/Intermediates.noindex/Previews/help/Products/Debug-iphonesimulator/help.app/ /Users/cpulipaka/Desktop/help.swiftpm/Resources/ZooClassifier.mlmodel ZooClassifier.mlmodel: No predominant language detected.

I want to get the loop times info in playground. But it seems to only display the latest result for a loop on the right side. Do I miss anything? Xcode 15.0.1 import Cocoa for i in 1...5{ print("\(i)") } I have a screenshot:

I have made a swift playground with the .playground extension but the WWDC24 Swift Student Challenge says I have to submit a .swiftpm file. What do I do to convert it to .swiftpm?

I was expecting all of the code to run in main thread, but both task and async function is working in backfround thread. Any explanations?

I'm getting the following error when previewing my Swift Playground package: Unrecognized platform name 'xrOS'; did you mean 'iOS'? Anyone know how to silence this? I don't have xrOS anywhere in my code so I'm guessing this is something with Swift Playgrounds or with the compiler.

Hello All, I happen to remove "Playgrounds" folder from my iCloud drive, and afterwards Playground is no longer functioning but repeatedly crashes. It was okey before deletion, but now any operation to create or download playground then Playground App crashes all the time. Issue not resolved even creating same name folder by manual, Issue not resolved even re-install Playground - folder in iCloud will not created. I guess I need to fully uninstall PlayGround completely, then start from scratch to let Playground App to hold init step to generate required folder in iCloud, but not sure how to do it. Please give kind help if anyone knows about this issue, or if anyone knows complete deletion step of Playground. Best wishes, tons of thanks in advance. Best Regards, Issey Hamada

Does anyone know of any documentation for the various directives in the guidebook? Things like @GuideBook, @Guide, @Task, @SuccessMessage, etc. Thanks, David

In Swift-UI Playgrounds Learn to Code 2 under the Chapter "Variables" and the exercise "Checking for Equal Values", there is no instruction to use the predefined variable numberOfSwitches in the goal instruction.

I've noticed Playgrounds crashing a lot lately, both on iPad and Mac. I have many Macs, Intel & M1, and 2 iPads, 7th Gen and 10.5" Pro. It's noticeably sluggish at the best of times progressively getting worse the last few updates, but worse than that it is hard crashing, losing data in the process. Anyone else seeing this? Not the end of the world, I'm a dev and use Xcode for anything substantial but I like to use Playgrounds on the iPad sometimes when I want to pop a quick idea down. I also plan to start creating playgrounds to help kids get into programming, so hoping this useful app isn't being neglected.

My Mac is older one. I just started to learn Swift. I want to practice it. So I downloaded Xcode 14.2 for MacOS 12.7.4 (21H1123) On tutorials, it is showing live result. But for me nothing is happening. It is blank. How do I enable it?

is there a beta version of Swift Playgrounds that supports the latest iPadOS 18 SDK, or do i have to use XCode on Mac?

I was watching this presentation about swift. A Swift Tour: Explore Swift’s features and design At timestamp 1:59, the presenter is using what looks sort of like swift playgrounds, however with a feature on the right hand side panel that is sort of like a REPL, and shows the value of an expression. How can I enable this feature? I am on the latest verison of Swift Playgrounds on macOS, and I cannot seem to find it.

Hi there, when I’m using Swift Playground app on my new M4 iPad pro software version 17.5.1 . Soon I’m running the code for the first time. It crashes the IPad and restart it. After it’s fine . Anyone else have the same issues ?

Is there any access to Swift Playgrounds on macOS12.3? On testflight or something?

Hi all! I am using Swift Playgrounds 4.5.1 on Mac and iPad. When I create new book, they both create new book with Swift 5.9 (instead of Swift 5.10). Is this a bug? The release notes says since 4.5.0 the Swift version has been upgraded to 5.10. Thanks B

I am writing an app in Swift Playgrounds 4.5.1 on an iPad 8th generation running iPad OS 17.5.1. When I click the run button I get the error “MyGame Crashed. Update failed. The operation couldn't be completed. (BSActionErrorDomain error 1.) MyGame may have crashed.” It was working up until a few days ago but now it can’t even show the preview. I haven’t updated the app or software since and I can run other app playgrounds. I have multiple nested views with multiple lists of buttons using ForEach statements and I am sharing variables across views using ObservableObject using code like this: class UserProgress: ObservableObject { @Published var score = 0 } struct InnerView: View { @ObservedObject var progress: UserProgress var body: some View { Button("Increase Score") { progress.score += 1 } } } struct ContentView: View { @StateObject var progress = UserProgress() var body: some View { VStack { Text("Your score is \(progress.score)") InnerView(progress: progress) } } }

I created an app using Playgrounds and added a Package from GIt. When I try running the app it fails saying the it doesn't support dynamic libraries. So, my question is why did it allow me to add the package in the first place?

I am currently running MacOS 12.7.6 version and this is the last update on my machine, and swift playgrounds is not downloading in it, so I want its older version, I think I need Swift Playgrounds 4.1, so please give me a solution. Thank you so much!

Hi! I have a remote student who's learning to code in Swift using Playgrounds - Learn to Code 2. It's frustrating to try to test his code when we think he as part of a solution to a puzzle because he can't run his code twice in the same puzzle without resetting the puzzle - when he tries, the page gives an error, and he has to reload the whole puzzle, which erases his code. As a workaround, he's been copying his code and reloading the puzzle whenever he wants to test out a partial solution. Is there an easier way to do this?
