LLDB RPC Server Crash Playground File XCode 16.0
When running the code below in a playground file, it crashes with an LLDB RPC Server crash. The crash log is attached. If I put the code into a project, it runs fine. lldb-rpc-server-2024-10-04-110747.txt import Foundation @objc protocol Speaker { func speak() @objc optional func tellJoke() } class Deb: Speaker { func speak() { print("Hello, I'm Deb!") } func tellJoke() { print("What did Sushi A say to Sushi B?") } } class Bryan: Speaker { func speak() { print("Yo, I'm Bryan!") } func tellJoke() { print("What is the object oriented way to become wealthy?") } func writeTutorial() { print("I'm on it!") } } class Animal {} class Dog: Animal, Speaker { func speak() { print("Woof!") } } var speaker: Speaker = Bryan() if speaker is Bryan { print("Hi, I'm a Bryan") } speaker.speak() //speaker.writeTutorial() //won't compile (speaker as!

Seriously? I can't deploy my demo to iPad cus swift 6?
Okay everyone who click into or just pass by this post ,to cut a farrrirly long story short ,here is the thing... I was devloping my app in the playground on my Mac , which was building for the iPad, In the early time of real machine commissioning(through the Xcode ),everything is okay everything is okay.. "well,mabe it's time to deploy my app to the playground in ipad"! Then,to top it all off🤣,then playground tell me (In case that you can't understand chinese and creat ambiguity ) emm that's too tight...,so I can only got back to the Xcode changing my language version to swift 5 then..... Noting change .... and I think err.. in order to properly deploy app to iPad ,I had to rework my code with swift 5! So, I almost fell on my knees ,can somebody who in charge of the playground ,can somebody who in charge of the playground ,just ,just! shove swift 6 in the playground (as long as it make my code run anyway), otherwise there's no way to debug it! please please plase!

Swift Student Challenge requires Swift Playground (.swiftpm), minimum OS setting not available.
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

Learn to code 3 missing
Hi Folks! Just started again with playgrounds, and had my "Learn to code 1-2-3" Apps on old versions. Updated 1 and 2 to 5.8, and just found that Learn to code 3 was still on old version (3.1), so decided to delete it. I was hoping that normally I'll just find it where the others are for download (Learn to code & Build Apps), but it is not there.. it is not anywhere, cannot find it, and couldn't find a way to download from anywhere else. Any ideas? Maybe for Learn to code 3 there is no Swift 5.8 yet? Thanks!
