Is it possible to create SwiftData Document-based apps in App Playgrounds (or Swift Packages, since App Playgrounds are a special type of packages)? As explained in wwdc2023-10154, to create a document-based app you are required to provide an UTType that conforms to com.apple.package. This requires your file type to be declared and exported in the Info.plist file of an Xcode project, but App Playgrounds don't have them. Providing .package as a UTType seems to partially work: import SwiftUI import SwiftData @main struct SwiftDataFlashCardSample: App { var body: some Scene { #if os(iOS) || os(macOS) DocumentGroup(editing: Card.self, contentType: .package) { ContentView() } #else WindowGroup { ContentView() } .modelContainer(for: Card.self) #endif } } This way I am able to run the app, create and edit new document, and save it on disk. However, opening it again does not work (you cannot select it since it is a folder without a defined package type). Is there any workaround to this? I guess I could drop support for multiple documents entirely if this is not possible (I don't think this would affect my submission), but I would just like to check if there is any way to do this first.

the code found in the file "Camera" in the template for "Capturing Photos" gives warnings that say How can I go around this by still keeping the same functions as the original "Camera" file? I am using a features that REQUIRES Mac Catalyst 17.0 or above.

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.

Hello, Very recently, the following code has automatically appeared at the bottom of three of my SwiftUI View files: @available(iOS 17.0, macOS 14.0, tvOS 17.0, visionOS 1.0, watchOS 10.0, *) struct $s10Accent_Ace33_0BADA584A03144EFDAB57154E6FD3FBALl7PreviewfMf_15PreviewRegistryfMu_: DeveloperToolsSupport.PreviewRegistry { static let fileID: String = "Accent_Ace/HistoryView.swift" static let line: Int = 47 static let column: Int = 1 static func makePreview() throws -> DeveloperToolsSupport.Preview { DeveloperToolsSupport.Preview { let randomWord1 = FetchWord.getRandomWord() let randomWord2 = FetchWord.getRandomWord() @State var randomWords = [Word(word: randomWord1.0, IPA: randomWord1.1, lineNumber: randomWord1.2), Word(word: randomWord2.0, IPA: randomWord2.1, lineNumber: randomWord2.2)] HistoryView(words: $randomWords) } } } This is from one of my files but it's very similar in the other two. It seems to have something to do with my previews. The problem is that this code generates an error: Ambiguous use of 'init(_:traits:body:)'. My previews worked just fine before the auto-generated code appeared, so I tried deleting it. However, it automatically comes back no matter how many times I get rid of it. It's preventing me from building my App Playground, so I can't run the app or even see the previews. Does anyone know how to get rid of it or fix the error? Thanks for the help!

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?

Hi guys! I want to know how can I create an array of UIImage elements and then access these elements randomly? I tried several times, but I have this issue: Can someone help me?

Hello, My App Playground uses a text file to work properly. I've had no issues running the app on Simulator, but it fails to find the file when being run on my physical iPhone. Has anyone had the same issue? Any idea what the problem is? Thanks for the help!

I've written the code exactly the way the tutorial explained. Word for word. The tutorial states to write @State var selected = "Bowling" but that doesn't work. I asked for help before but no one replied. So I thought I would post again with the code.

Thanks for zero replies. I can't believe that 28 to 51 people looked at my post and no one responded back. Anyway, I figured it out on my own after taking a break. I was just asking in so many words, where do I put the bold highlighted code. WHY NOT TRY app completed………. // // ContentView.swift // WhyNotTry // // Created by Geraldine Jones on 1/26/24. // import SwiftUI struct ContentView: View { var activities = ["Archery", "Baseball", "Basketball", "Bowling", "Boxing", "Cricket", "Curling", "Fencing", "Golf", "Hiking", "Lacrosse", "Rugby", "Squash"] var colors: [Color] = [.blue, .cyan, .gray, .green, .indigo, .mint, .orange, .pink, .purple, .red] ******** @State private var selected = "Baseball"******** @State private var id = 1 var body: some View { VStack { Text("Why not try...") .font(.largeTitle.bold()) VStack { Circle() .fill(colors.randomElement() ?? .blue) .padding() .overlay( Image(systemName: "figure.\(selected.lowercased())") .font(.system(size: 144)) .foregroundColor(.white) ******** .transition(.slide)******** ******** .id(id)******** ) Text("\(selected)!") .font(.title) } Spacer() Button("Try again") { ****** withAnimation(.easeInOut(duration: 1))****** { selected = activities.randomElement() ?? "Archery" ********id += 1******** } } .buttonStyle(.borderedProminent) } } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() } }

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 { // ... } }

I am developing my app for the Swift Student Challenge 2024. I have made significant progress on it and have been building it on a M1 Mac, where it works perfectly. However, when testing it on some iPads (specifically, the iPad Pro 2018 and iPad Air 5 M1), it did not perform well on these devices. I am wondering if I can specify whether the app should be reviewed on a Mac (M1 or later) or if it will be reviewed on an iPad.

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.

Hi! I'm preparing to apply for the Swift Student Challenge and had a question. In the terms and conditions, it says "Your app playground must be built with and run on Swift Playgrounds 4.4 or later (requires iPadOS 16 or macOS 13.5) or Xcode 15 on macOS 13.5 or later. You may incorporate the use of Apple Pencil." Does this mean that my app must run on iPadOS 16 or macOS 13.5, or can it run on iPadOS 17 or macOS 14 or later as long as it runs on Playgrounds 4.4? In other words, what should I set my Deployment Target to? Thanks for your help in advance 😜

Hello everyone, Is there a way to set the minimum deployment target in Xcode Playground?

Hello, I'm developing an app for Mac, Xcode 15.1, with Swift 5. I need to create a visual matrix, whose elements will be filled randomly, according to the choices the user makes. The matrix must have 10 columns and 40 rows. Does anyone know a component, or how to fill it dynamically and randomly? Thanks.

Hey folks! I remember some weeks/months ago to get some lessons with updated Swift 5.9, I'm just not sure if this happened while I was using Swift Playgrounds beta from TestFlight. Anyways, I went back to study using Swift Playgrounds and all the lessons are using Swift 5.8 here. I don't know what happened or how can I have the lessons updated again. Anyone else noticed this issue? Any tip on how to solve it?
