Hello there! I would like to build a playground using Swift Playgrounds in AR. And I want to ask if it is possible to do it on the Mac or I can only do it with the iPad? Thank you.

Hello there! I want to create a cards game, and I'm creating it following the Stanford University's tutorial. I followed the video step by step but there is a warning that In the video doesn't appear. Can someone help me to fix it? Here's the link of the video: [https://www.youtube.com/watch?v=oWZOFSYS5GE&t=671s) This is my code: import SwiftUI struct ContentView: View {     let viewModel: EmojiMemoryGame     var body: some View {         VStack {                 LazyVGrid(columns: [GridItem(), GridItem(), GridItem()]) {                     ForEach(viewModel.cards) { card in                         CardView(card: card)                             .aspectRatio(aspectRatio, contentMode: .fit) // here's the first error which says "Cannot convert value of type '(CGFloat?, ContentMode) -> some View' to expected argument type 'CGSize'"                     }                 }                 .padding()                 .foregroundColor(Color(.systemTeal))                                  Spacer()                 Button {                     emojiCount += 1                     if emojiCount == 10 {                         aspectRatio = 9/3                     } ì                     if emojiCount > 17 {                         print("Card finished")                     }                 } label: {                     Text("Add Card")                 }             }         }     } struct CardView: View {     let card: MemoryGame<String>.Card          var body: some View {         ZStack {             let shape = RoundedRectangle(cornerRadius: 20)             if card.isFaceUp {                 shape.fill().foregroundColor(.white)                 shape.stroke(lineWidth: 3)                 Text(card.content).font(.system(size: 50))             } else {                 shape.fill(.orange)             }         }     } } struct ContentView_Previews:     PreviewProvider {         static var previews: some View {             ContentView(viewModel: game) //here's the second error which says "Cannot find 'game' in scope"     } }

Hello everyone! I have updated my iPhone to iOS 15.2.1 and before this update my phone after the good the sleep mode turns off, it appears a screen with written on it “Good Morning” and the weather. But since I have updated my device to iOS 15.2.1 it isn’t showing me this screen. Is it a feature that Apple has deleted or is this a bug? Thank you.

Hi there! I'm trying to create an app which scrolls automatically when my mouse goes to the top of the screen or to the bottom. For example the mouse goes towards the top, it has to scroll to the top and vice versa. So if it possible help me please. Thanks very much! I leave you my code: import SwiftUI import PlaygroundSupport struct ContentView: View {     var body: some View{         HStack {             CardView()             CardView()             CardView()             CardView()         }         .padding()         .foregroundColor(Color(.systemRed))     } } struct CardView: View {     @State var isFaceUp = false     var body: some View {         ZStack {             let shape = RoundedRectangle(cornerRadius: 20)             if isFaceUp {                 shape.fill().foregroundColor(.white)                 shape.stroke(lineWidth: 3)                 Text("😀").font(.system(size: 80))             } else {                 shape.fill()             }         }          .onTapGesture(perform: {             isFaceUp = !isFaceUp         })     } } PlaygroundPage.current.setLiveView(ContentView())

Hey there, I would like to create a card game (I'm following the Stanford University's tutorial) and I want to Scroll the view according to the position of the mouse, like if it's to the top so I would like that it automatically rolls up, so if it's to the down, scroll automatically to the down: This is my code: import SwiftUI import PlaygroundSupport struct ContentView: View {     var body: some View{         HStack {             CardView()             CardView()             CardView()             CardView()         }         .padding()         .foregroundColor(Color(.systemRed))     } } struct CardView: View {     @State var isFaceUp = false     var body: some View {         ZStack {             let shape = RoundedRectangle(cornerRadius: 20)             if isFaceUp {                 shape.fill().foregroundColor(.white)                 shape.stroke(lineWidth: 3)                 Text("😀").font(.system(size: 80))             } else {                 shape.fill()             }         }          .onTapGesture(perform: {             isFaceUp = !isFaceUp         })     } } PlaygroundPage.current.setLiveView(ContentView())

Hello! I was trying to create a cards game following the Stanford University CS193p tutorial and I had a problem, in the tutorial they didn't add any animation and I would like to add one but I can't understand where exactly I have to write the command. Can someone help me? Thank you very much!

Hello everyone, I was trying to create something in Swift Playgrounds when this error appears, can someone tell me what it means and how can I fix it? Thanks

Hello there, What is the difference between @ObservedObject, ObservableObject and @StateObject in SwiftUI?

Hi guys, I need a little help with my code, I was creating this playground and I want that the cards will stay face up if they are equal... I can't find tutorial and I tried different lines of code but it doesn't work. So please can anyone help me there? I'll thank you very much. struct ContentView: View {     @State var flipped1 = false      @State var flipped2 = false      var body: some View {               LazyVGrid(columns: columns) {             Group {                 RoundedRectangle(cornerRadius: 20)                     .frame(width: 140, height: 170)                     .foregroundColor(flipped1 ?

Hi guys I'm trying to build a game (cards game precisely) and I need that when the user finds the same cards the game has to stop...

Hello guys, everything was working perfectly but I can't do a thing please help me. I was trying to put into this Rectangle some text , I've tried several lines of code but I can't put the Text INTO the rectangle. Can someone help me?

Hello everyone, I would like to a flip animation, so that when I press on the rectangle it will flip to other side (like in a cards game) How can I do that? Thank you Here's my code: import SwiftUI import PlaygroundSupport struct ContentView: View {     var body: some View {                      Group {                 Button {                                      } label: {                     Rectangle()                         .frame(width: 140, height: 170)                         .foregroundColor(Color(.systemTeal))                         .cornerRadius(20)                 }             }     } } PlaygroundPage.current.setLiveView(ContentView())
