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?

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.

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.

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

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

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.

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 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 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:

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.

Hey Developers, I'm on the hunt for a new Apple laptop geared towards coding, and I'd love to tap into your collective wisdom. If you have recommendations or personal experiences with a specific model that excels in the coding realm, please share your insights. Looking for optimal performance and a seamless coding experience. Your input is gold – thanks a bunch!

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.

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 :)

Hello, is the new Journaling Suggestions API available in App Playgrounds (made using Xcode)? I know I can add capabilities in Xcode, but it seems that the Journaling Suggestions capability isn't available. I assume this API is currently unsupported in App Playgrounds?

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 { // ... } }

Hi! I'm preparing to apply for the Swift Student Challenge and had a question, how can I find info.plist in Xcode 15.2 playground I will do a game AR game and I need info.plist to access to camera so how can I find info.plist ?

I am using Swift Playground to teach "coding" to my nephew. One of the strict requirements I am trying to explain him is: when you are required to solve a problem, you need to use only the instructions/harward/etc you have available. In the first episode of "Get started with code" -> "Commands" -> "Issuing commands", you are presented with two commands moveForward() and collectGem(). In the second episode "Toggle a Switch" you are introduced to a new command "toggleSwitch()". Up to this point, the learner was introduced to three commands: moveForward(), collectGem(), toggleSwitch(). However, in order to solve the puzzle in the second episode, you need also to use another command: turnLeft(), that has not been referenced. It is clear that looking for unknown commands is part of learning to code, but this occurs too early in the playground. Please consider also that some non-English young learners have no idea on how to write "turn left", so they cannot even type the first letters and hope in the auto-completion of the commands. This has not been well thought by the designers of the playground.
