Hello everyone! I'm having a problem with my code and I don't know how to fix it. In fact, when I click the green circle, it gets bigger by wiping out the others, but the purple overlaps. Is there a way to get the purple away too? Another problem: I have a warning where it says  .animation(.spring()) and the warning says "'animation' was deprecated in iOS 15.0: Use withAnimation or animation(_:value:) instead." import SwiftUI struct ContentView: View {         var body: some View {             LazyVGrid(columns: [GridItem(), GridItem(), GridItem()]) {                 createCircle()                     .foregroundColor(.blue)                 createCircle()                     .foregroundColor(.green)                 createCircle()                     .foregroundColor(.purple)                 createCircle()                     .foregroundColor(.orange)                 createCircle()                     .foregroundColor(.yellow)         } } struct createCircle: View {     @State var scale : CGFloat = 0.25     var body: some View {         ZStack {             Circle()                  .frame(width: 500 * scale, height: 500 * scale)                  .onTapGesture {                      scale = 5                  }                  .animation(.spring()) // WARNING: 'animation' was deprecated in iOS 15.0: Use withAnimation or animation(_:value:) instead.                  .animation(.interpolatingSpring(stiffness: 50, damping: 1), value: scale)         }     } } } Can anyone help me?

Hi there! I have a public structure and I called it in my ContentView, but I can't understand where to punt the var/let. I try to put them before "var body: some view" but it gives me these errors.

Hello developers! I have a question about which programming language is good for building a website. I searched on the internet and it says that CSS and HTML are the most used, so suppose I want to use CSS, now the question is: where can I code to build the website? For example if I want to code in SwiftUI there are some apps (Xcode and Swift Playgrounds) to do it, but how can I do with the website in CSS? If someone has the right answer, please help me. Thanks.

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?

Hi everyone! import SwiftUI struct ContentView: View { let screenHeight = UIScreen.main.bounds.height let letters: [String] = ["A", "B"] @State private var yOffset: CGFloat = 0.0 var body: some View { ForEach(letters, id: \.self) { letter in Text(letter) .padding() .font(.largeTitle) .offset(x: 0, y: yOffset) .animation(Animation.linear(duration: 5.0).repeatForever(autoreverses: false)) .onAppear { yOffset = screenHeight - 90 } } } } I would like in this code, the letters to fall from the beginning of the screen to its end, I have the size of screen's height, but actually I can't understand how I can I use it, until the letters can start from the beginning of the screen. And I would also like that once they reach the bottom, they start falling again... I can't understand how this effect can be achieved, is there anyone who can help me?

Hi, I've created an effect that after clicking on the "Hello, world!" button, it has to move (first move is when the user taps on it), and then it has to move again, but this time without any interaction, and it does. But the problem is that when I click again on it, it goes back and then returns to the same position, I can't understand how to solve this issue. This is my code: import SwiftUI public struct ContentView: View { @State var xPos: CGFloat = 300 @State var yPos: CGFloat = 400 @State var size: CGFloat = 120 public var body: some View { ZStack { Image("background") .resizable() .frame(width: 700, height: 500) .padding() .overlay { Button(action: { xPos = 170 yPos = 310 size = 60 DispatchQueue.main.asyncAfter(deadline: .now() + 1) { xPos = 700 } }) { Text("Hello, world!") .font(.system(size: size)) .position(x: xPos, y: yPos) } .animation(.spring) } } } } Can anyone help me? Thanks in advance!

Hi, I heard that Apple will send me an email saying that my Apple developer membership is activated, with the confirmation and I can start exporting and publishing apps, but to me came 3 emails: welcome to the Apple Developer Program App Store connect good news!
