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 Playgrounds 4.6.1 Removes Subscription Feeds
I use Swift Playgrounds on iPad to run an intro to programming class with high school students. I've created some custom playground books based on Apple's guides to provide some simple sandboxes to learn basic coding. Students simply click a button on my website, which downloads my playground books so students can easily create new sandboxes. With Swift Playgrounds 4.6.1 on both Mac and iPad, clicking the link only opens Swift Playgrounds and does not download my playground books! There used to be an "Add a Subscription URL" button, but it is no longer present on the Learn to Code page or anywhere else in the app that I can find: Is it intentional that this functionality is removed? Playground Books still appear to work, and documentation for subscription feeds is still available. I start another session with my students next Monday, so I need to know as soon as possible whether I need to plan to work around this myself. Thanks, Mark Schmidt

Xcode: Skipping Duplicate Build File in Compile Sources in a .swiftpm Project – How to Fix?
I'm trying to add Assets.xcassets to a .swiftpm project, but I'm getting the warning: ⚠️ Ignoring duplicate build file in build source build phase (Just to know, that is about developing in XCODE, in Swift Playgrounds does not appear it, even in this second being harder to setting up) The problem is that there are no “Build Phases” in XCODE to remove duplicate files manually. I've already tried adding the path of Assets.xcassets in the resources property of Package.swift, like: .executableTarget( name: "AppModule", path: ".", resources: [ .process("Assets.xcassets") ] ) Even so, the warning persists. Does anyone know how to solve this? Is there any way to remove duplicate references or force a cleanup of the Swift Package Manager cache to fix it? I appreciate any tips! 🙏🚀

How can I use a CreateML model in Swift Playgrounds
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?

Swift Playgrounds Incompatibility with Xcode 16 Files and Swift Versions
I'm facing an issue with Swift Playgrounds and files created in Xcode 16. It seems that Swift Playgrounds does not support Swift 6, but even when I create files specifically with Swift 5, Swift Playgrounds still reports that the files are unsupported. This creates a significant problem because macOS Sequoia does not allow me to revert to Xcode 15, which might have offered better compatibility. As it stands, I can't find a solution to work seamlessly between Xcode and Swift Playgrounds. Has anyone else encountered this issue? Are there any workarounds or updates planned to address this compatibility gap? Any advice would be greatly appreciated!

Swift Playgrounds Will Not Upload to App Store Connect
When I go to the App Settings menu in Swift Playgrounds and attempt to upload to App Store Connect, I run into the below error screen: I am registered with the Apple Developer Program. Swift Playgrounds is updated to its latest version. This is occurring on both macOS and iPadOS. All the information I put in is valid. Any reason why this would be happening?

Swift Playgrounds on iPad localization
Hey, meanwhile it's a great thing to program apps on the iPad and to be able to load them into the App Store Connect and the App Store. What about localization in the meantime? When I open the folder en.lproj in sample apps from XCode, then there are two files stored in it: Glossary.plist (XML) and Localizable.strings (binary) Is it correct that XCode creates binary files from the strings? Otherwise, Swift Playgrounds already offers localization in the localized learning content, but i guess the binary files can only be created in XCode?

Bug in ‘Learn to Code 2’ – ‘Variables: Seeking Seven Gems’ Causing Errors Regardless of Actions
I’ve encountered a bug in Swift Playgrounds within “Learn to Code 2”, specifically in the “Variables: Seeking Seven Gems” section. No matter what I do—or even if I do nothing at all—an error always occurs. I’ve tested this on both an iPad (9th generation) and an iPad Pro 11-inch (4th generation), and the issue happens on both devices. Has anyone else experienced this? Any ideas on how to fix or work around it? Thanks!

PlaygroundSupport no longer available for Playground apps
In Swift Playground 4.6.2 the package PlaygroundSupport is no longer available to Playground apps. The following test previously permitted apps run in the Playground vs compiled in XCode to support different behavior: #if canImport(PlaygroundSupport) container = NSPersistentContainer(name: "myApp", managedObjectModel: Self.createModel()) #else container = NSPersistentCloudKitContainer(name: "myApp") #endif Since Swift Playground 4.6.2 the PlaygroundSupport package is no longer available for app projects in Playgrounds. Is there a different compile type test which can be used to differentiate compilation for Swift Playground apps ? I am currently having to use a runtime workaround (below) but would prefer a compile time test is an alternative is available. public static var inPlayground: Bool { if Bundle.allBundles.contains(where: { ($0.bundleIdentifier ?? "").contains("swift-playgrounds") }) { return true } else { return false } }

Swift Playground 4.6 - App Fails to Run with import AppIntent
Hi everyone, I’ve been developing an app using Swift Playgrounds, and it was working fine in version 4.5. However, after updating to Swift Playground 4.6, the app no longer runs. After some testing, I found that the issue occurs when import AppIntent is included. Here’s a simple example: import SwiftUI //import AppIntents // <- If this line is included, Preview and Run fail. @main struct MyApp: App { var body: some Scene { WindowGroup { Image(systemName: "globe") .imageScale(.large) .foregroundColor(.accentColor) Text("Hello, world!") } } } Has anyone else encountered this issue? Thanks!
