Print something on the screen
Hello there! I would like to print the number 5 on the screen when I click the Button, but I don't know how I can do it... if I write print("5") it prints me the number 5 in the debug area of Xcode. Can someone help me to figure out this? Here's may code Thanks a lot 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)         }

How to fix these errors?
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"     } }
