I've defined the text here, how can I change the value of it? VStack{             Text("text")                          Button {                              } label: {                 ZStack {                     Circle()                         .frame(width: 90, height: 90)                         .foregroundColor(Color(.systemBlue))                         .opacity(0.5)                                          Text("5")                         .font(.largeTitle)                         .bold()                         .foregroundColor(.black)                 }                 .frame(width: 90, height: 90)             }         }

I'm trying to do it in Swift Playgrounds and here's my code: import PlaygroundSupport let columns: [GridItem] = [GridItem(.flexible()),                            GridItem(.flexible()),                            GridItem(.flexible())] struct ContentView: View {     var body: some View {         GeometryReader { geometry in             VStack {                 Spacer(minLength: 290)                 Text("text")                     .font(.largeTitle)                 ZStack {                     LazyVGrid(columns: columns) {                         Group {                             Button {                                                              } label: {                                 ZStack {                                     Circle()                                         .frame(width: 90, height: 90)                                         .foregroundColor(Color(.systemBlue))                                         .opacity(0.5)                                     //.position(x: geometry.size.width/2, y: -100)                                                                          Text("5")                                         .font(.largeTitle)                                         .bold()                                         .foregroundColor(.black)                                 }                                 .frame(width: 90, height: 90)                             }                         }                     }                 }             }                      }                                  } } PlaygroundPage.current.setLiveView(ContentView()) I've created a text and I would like that the text will change on the press of the button. For example: there's a Text() witch now has written on it "text" and when I press the blue button (you can see it in my code), I want "text" to change to number "5"

I have tried, but it gives me this error…

I created the structure down the "let columns" above the ContentView and I called the NumberView in the Button's action and now the error it's gone. But when I play my code and click the button it doesn't show me the text. Can't understand why...

Okay thanks!

Great idea, but I don’t think that it changes to much, already iPhone or other Apple products are very simple to use (brilliant colors, icons, animations, accessibility features and more). I see many old people transferring to iPhone because of its simplicity… And all the features you said are already possible, so we don’t have to make easier a thing that is already easy, doing so it will become more complex for us and also for the user

Now it's working. Thanks to both of you!

So Swift Playgrounds isn’t for building apps?

ok, so can I use the Mac Swift Playgrounds too?

But for creating a playground instead of an app is it ok?

But isn’t TestFlight just for publishing apps?

I putted .overlay(Text("Hello, world!")) before .rotation3DEffect(self.flipped1 ? Angle(degrees: 180): Angle(degrees: 0), axis: (x: CGFloat(0), y: CGFloat(10), z: CGFloat(0))), so this is my syntax now: RoundedRectangle(cornerRadius: 20)                     .frame(width: 140, height: 170)                     .foregroundColor(self.flipped1 ? .yellow : .purple)                     .padding()                     .overlay(Text("Hello, world!"))                      .rotation3DEffect(self.flipped1 ? Angle(degrees: 180): Angle(degrees: 0), axis: (x: CGFloat(0), y: CGFloat(10), z: CGFloat(0)))                     .animation(.default)                      .onTapGesture {                         self.flipped1.toggle()                     }  I want the rectangle to show the text only on one face (only when it is flipped)... Instead now he shows it on all 2 faces

Yes it is correct. Thanks very much!

Thanks very much, it's exactly what I want! Can you explain me what you did in the tapped() function? Because it's a little bit confusing to understand.

Where did you define the number of the cards?
