Hello there! I was trying to build an app with the new App feature in Swift Playgrounds for Mac. But I have an error message in my code, and I can't understand how to fix it. Can anyone help me to solve this error.
Here's the code:
import SwiftUI
struct Something: View {
let rows = 17
let columns = 17
let size: CGFloat = 10
let blocks: [[Color]] = [[.purple, .purple]]
var body: some View {
VStack {
ForEach((0...self.rows - 1), id: \.self) { row in
HStack (spacing: 0) {
ForEach((0...self.columns - 1), id: \.self) { col in
VStack (spacing: 0) {
Rectangle()
.frame(width: self.size, height: self.size)
.foregroundColor(self.blocks[row][col]) // index out of range: the requested index was outside the bounds of the array.
}
}
}
}
}
}
}
Hello everyone! I recently updated my Mac to macOS Ventura, everything was updated as expected, but I'm having a problem with Xcode, I also updated Xcode, but when I clicked on it for opening it, a message appeared which says that "In order to use Xcode, you need to update to the latest version" (despite having already updated it), so, when I go on App Store for updating it again, it already says me to open, and there isn't the Update option.
I'm troubling with this problem... please if anyone knows how to fix it, help me.
Thank you.

Hello everyone!
I had a question about the Apple’s WWDC Special event, hope someone can resolve my doubts.
For taking part of this event, will the event for invites be online or we have to go at Cupertino?
Because I read some articles that says the event for developers will in-person. Quindi sono un po’ confusa, per favore aiutatemi se riuscite ;)

Hi there!
I want to attach 2 objects in SwiftUI when they'll near.
import SwiftUI
struct ContentView: View {
@State private var dragOffset: CGSize = .zero
@State private var position: CGSize = .zero
var body: some View{
Circle()
.frame(width: 140, height: 140)
.foregroundColor(.green)
.position(x: 150, y: 90)
.offset(x: dragOffset.width + position.width, y: dragOffset.height)
.gesture(DragGesture()
.onChanged({ (value) in
self.dragOffset = value.translation
})
)
Circle()
.frame(width: 140, height: 140)
.foregroundColor(.blue)
.position(x: 500, y: 210)
Circle()
.frame(width: 140, height: 140)
.foregroundColor(.orange)
.position(x: 90, y: 70)
}
}
In my code I want to stick the green circle with one of the other 2, when it is close to them.
Can anyone help me figure out this?
Thanks in advance.

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?
