Playgrounds
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.

Playground can not create newbook / download sample playground after iCloud folder deletion, but it crashes
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

CoreML in playgrounds
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.

Swift Student Challenge Vision
Hi Developers, I want to create a Vision app on Swift Playgrounds on iPad. However, Vision does not properly function on Swift Playgrounds on iPad or Xcode Playgrounds. The Vision code only works on a normal Xcode Project. SO can I submit my Swift Student Challenge 2024 Application as a normal Xcode Project rather than Xcode Playgrounds or Swift Playgrounds File. Thanks :)

Cycles in picker view
Hi everyone, I just finished my first app and I have a doubt about whether picker view automatically makes a series of loops in its func. I put some prints inside the funcs and this is the result only when starting the view with the picker: Every time I select it the cycles continue. It's normal? Is there a way to avoid or control it? Thanks in advance for any response.

The WhyNotTry tutorial
https://www.swift.org/getting-started/swiftui/ Is there a better tutorial than this one. Can't seem to find a live youtube video that teaches it. I went to git hub and downloaded the source code but all it shows is a big round blue circle. I can't seem to get pass the below code without it giving me an error. I need to see this tutorial live. Any suggestions? struct ContentView: View { var activities = ["Archery", "Baseball", "Basketball", "Bowling", "Boxing", "Cricket", "Curling", "Fencing", "Golf", "Hiking", "Lacrosse", "Rugby", "Squash"] var selected = "Archery" var body: some View { // ... } }
