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?

Fatal Error in Swift Playground
Description
I'm experiencing a catastrophic error when importing Package Dependency in any Swift Playgrounds that has icon or name that caused the whole Playground won't work anymore with error messages below.
I'm current running macOS Sequoia 15.3 (24D60) and Swift Playgrounds 4.6.1. They're all up-to-date.
Reproduction
Open Swift Playgrounds and and create a new project.
Import a package dependency
https://github.com/simibac/ConfettiSwiftUI.git
Rename the project and add an icon
Then you should able the reproduce the problem. I strongly believed that this is a serious bug.
You'll find that Assets in the left column are disappeared and appeared Assets.xcassets, you're unable to reveal the Dependency in the column like the reference picture above. The whole Playground is destroyed now and unable to work anymore.

Hello! I have asked this question in previous years, but I want to make sure I can be safe as each challenge could be different.
Are applicants for the Swift Student Challenge allowed to use the features and technologies involved with Metal/MetalKit? Last year, the answer was yes. I have seen a few people here and there use it with Swift and won.
I would like to know if we can use it for the 2025 challenge for this year as well.
Thanks! :)

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! 🙏🚀

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!
Hi, friends!
I have a Keynote file, in which I create design for macOS applications settings and system settings, that I use and which are installed on my Mac.
I like to record my settings so that every time I reinstall the system or an application I can open my file and set it up exactly the way I want. It's like a user manual, only it looks nice with Mac design elements. And I do it in a presentation (Keynote). I also use a Sketch for the design.
I want to turn all this into an app for myself, using Swift Playground.
Does anyone know how to, for example, add a macOS Dock icon from a Sketch to Swift Playground?

I am trying to complete the "Initializing Your Expert" lesson in the Swift Playground. Below I post just a snippet of the code that I wrote, since no matter how many lines of code I write, the turnLock() method has no effect whatsoever.
let expert = Expert()
/*Create a function that will move the Expert character forward
the specified number of tiles. This will make the program easier to code and less verbose.
*/
func moveExpert(tiles: Int) {
for tile in 1...tiles {
expert.moveForward()
}
}
/*Create a function to make the Expert do an about face, i.e.
orient itself in the opposite direction.
*/
func aboutFace() {
expert.turnRight()
expert.turnRight()
}
expert.turnLockUp()
The instructions give no information about this method, such as when or where it can and cannot be called. It states merely that calling it is supposed to "reveal the path between the platforms." I don't see multiple platforms in the 3D puzzle world, just one platform with different levels.
No "path between platforms" is ever shown when I call this method, regardless of the location of the Expert character. Why doesn't this method ever do anything at all?
Can anyone advise?
Thank you kindly.

Hello All,
I am currently working through ”Keep going with Apps” in Swift Playground. The section in the tutorial “Add a DancingCreature view” will not complete. I have tried to type it is as written in the tutorial and even used the copy and paste button provided. I have restarted the app and my IPad with no success. I have attached a screen shot of the tutorial prompt.
Here is the code block:
import SwiftUI
import Guide
struct DancingCreatures: View {
//#-learning-code-snippet(varDeclaration)
@EnvironmentObject var data : CreatureZoo
var body: some View {
SPCAssessableGroup(view: self) {
VStack {
ZStack {
/*#-code-walkthrough(dance.forEach)*/
ForEach(data.creatures) { creature in
/*#-code-walkthrough(dance.forEach)*/
/*#-code-walkthrough(dance.textView)*/
Text(creature.emoji)
.resizableFont()
.offset(creature.offset)
.rotationEffect(creature.rotation)
/*#-code-walkthrough(dance.textView)*/
}
}
ZStack {
/*#-code-walkthrough(dance.forEach)*/
ForEach(data.creatures) { creature in
/*#-code-walkthrough(dance.forEach)*/
/*#-code-walkthrough(dance.textView)*/
Text(creature.emoji)
.resizableFont()
.offset(creature.offset)
.rotationEffect(creature.rotation)
/*#-code-walkthrough(dance.textView)*/
//#-learning-code-snippet(exp1)
//#-learning-code-snippet(animationSolution)
//#-learning-code-snippet(exp3)
}
}
/*#-code-walkthrough(dance.onTap)*/
.onTapGesture {
data.randomizeOffsets()
}
/*#-code-walkthrough(dance.onTap)*/
/*#-code-walkthrough(dance.onTap)*/
.onTapGesture {
data.randomizeOffsets()
}
/*#-code-walkthrough(dance.onTap)*/
}
}
}
}
struct DancingCreatures_Previews: PreviewProvider {
static var previews: some View {
DancingCreatures().environmentObject(CreatureZoo())
}
}
Device information: IPad Pro (11 inch, 2nd gen)
iPad OS Version: 26.0.1
Playground Version: 4.6.4
Anyone else come across this?
Thank you in advance.
I am a high school teacher from China, currently teaching programming courses at my school. Several issues are preventing the course from being completed on schedule. As shown in the image, there are two problems:
The preview issue has existed since updating to the latest software and system version; I don't know how to resolve it.
After renaming a Swift file, this window keeps popping up, even after closing it.
This problem didn't exist last year. How can I fix this? Thank you for your reply!
我是一名来自中国的高中教师,目前在学校开设编程课程,目前有几个问题导致课程无法如期完成。如图所示,存在两个问题:
一、自从更新了最新版本的软件和系统后,预览问题就存在,不知该如何处理
二、swift文件重命名后,一直跳出来这个窗口,关掉以后还是跳出来
去年的时候还没有存在这样的问题,请问我该如何处理,感谢您的回复!

I am trying to challenge myself by building an iPhone app in Swift Playgrounds. I just got a Mac Mini M4, so I am trying Swift Playgrounds for Mac.
I can submit a build to TestFlight, but it's for Mac and won't let me even test on my iPhone.
How can I build my app for iPhone?
The least "hacky" answer is appreciated, but I'll entertain anything. Examples in order of hackiness might be:
I missed an option in Playgrounds for Mac.
Open my playground in Xcode, change something, open back in Playgrounds for Mac.
Same as above, but maybe I have to add/copy a file (e.g., manifest.plist).
Open my playground in Playgrounds for iPad (I have an iPad 9), do something, copy back to Playgrounds for Mac.
Submit via Playgrounds for iPad.
Submit via Xcode.
BTW, I'm challenging myself not just for its own sake, but because I'm curious how far a student/newbie/etc can take Swift Playgrounds. I was hoping to set a good example for others looking for a lighter-resource, more user-friendly experience than Xcode (which is why I assume Playgrounds for Mac even exists). But right now it feels like Playgrounds for Mac is a … third-class citizen? Maybe the iPad version is second-class? I haven't really tried it.
P.S. Why does this text editor seem so lame? Making a numbered list and adding to it is a nightmare. Should be: start a numbered list, hit return, new number appears below. I'm on Safari. This should be the best dev experience on the planet, not the worst!

I am currently developing my submission for the SSC and I noticed that the swift playgrounds app for iOS does not have support for the new swift ui features in iOS 18. Are we allowed to submit apps that use these iOS 18 only features?

I've entered some code on Version 4.5.1 of Playgrounds on my iPad mini running iOS 18.1.1. The file is saved on iCloud and so is available on my Mac running OS 15.2. However, the file will not open in either Playgrounds v 4.5.1 on the Mac (error "Unable to get file wrapper for contents.xcplayground.") or Xcode 16.1 (error "Couldn't load settings from contents.xcplayground"). The file's type is .playgorund. Any thoughts?
I’m curious about the situation since the Playgrounds haven’t released a new version to support the numerous new frameworks released this year at WWDC24. How are we supposed to build with these new frameworks if they haven’t even been released for Playgrounds for the Swift Student Challenge?

Some reason the image 'Ren' is not being loaded even though it is in the project how can I resolve this issue in Xcode Playgrounds?
Hi, I have recently downloaded the app to start learning how to code in swift and so on.
On my first try I have gotten the error stating that ”.swiftpm files cannot be opened”. I have followed some forum posts. I restarted my iPad several times and redown the app several times. I tried to disable the iCloud sync but I think I deleted the iCloud directory entirely that just results in the app closing on any action taken. (such as pressing the “New App” option or choosing the quick actions to make apps).
Is there a way to fix this?
Any help is appreciate, please ask me to provide any extra needed information.

Hello! I would like to use Speech Framework on my App Playground for this year challenge. But I still can't understand if I am allowed to use it to respect the rule of "not rely on a network connection". That's why:
Speech framework can use on-device Speech recognition –
No internet connection needed ✅.
But it can ask to download an Apple's native language package to use it for this on-device recognition – To get this, you need to be connected to the Internet ❌.
When I try to add a Speech Recognition Capabilities on my App Playground, its' description says: "Required to perform speech recognition using Apple's servers." (screenshot is attached). Does it mean that I won't be able to use on-device recognition on my App Playground? – And therefore, only online-version of this framework is available and I can't use it to participate on the challenge successfully❓.
If it's possible, could you please make it clearer? This framework is crucial for my App Playground and I really need this to make it work.
Thanks for your help in advance! And a have a good day!
Hello! I have a quick question about locking orientation and disabling Multitasking/Slide Over in a .swiftpm for the Swift Student Challenge.
A .swiftpm file contains a Package.swift file. At the top of this file, there is a very scary warning that directs you to not edit it. However, being unable to edit this means that I cannot lock the orientation of an iPad and disable Multitasking/Slide Over.
I have read that it does not break your project if you ignore the warning and I tried it out for myself — editing the file does indeed lock orientation and disable Multitasking/Slide Over! Although, as you can imagine, this is quite nerve-wracking.
What are the actual technical implications of doing this? Are participants allowed to do this?
If this does not seem like a good idea, would judges follow through with a note that tells them to simply not use certain orientations and Multitasking/Slide Over? (Yeah, I know… not an ideal thing but if there’s anyone to understand it would be Apple employees).
I am faced with two uncertain options: ignore a warning and get what I need or follow the warning but then have a very poorly designed experience (some apps just aren’t meant for portrait and Multitasking/Slide Over, even if this is not a full app).
I definitely don’t want hundreds of hours of work to go down the drain or risk rejection because of some type of problem with this, that’s for sure. Perhaps a “hack” would work if I were creating an actual app, but the stakes become higher when it is for this challenge.
Thanks! :)
