Hi everyone! I was working on a playground in Swift Playground and I got an error. I can't understand what this error means, can anyone help me?
This is my code:
struct Preview: View {
@State var isPlaying = true
@State var num1 = 60
@State var num2 = 150
var body: some View {
if isPlaying == true { // ERROR: Only concrete types such as structs, enums and classes can conform to protocols
// Required by static method 'buildBlock' where 'C0' = ()
num1 += 1
print("\(num1)")
}
}
}
Thanks.

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?
Hi there! I'm trying to build something in SwiftUI and I need a help on it. I want the orange circle to scale and expand, and fill the entire screen, whenI click on it.

var body: some View {
Circle()
.frame(width: 120, height: 120)
.foregroundColor(.orange)
}
}
Thank you.
Hello guys! Can I attach one object to another using a magnate animation in SwiftUI? For example In the code below I want the blue square to attach with the red one, when I drag it near it.
Here's. my code:
import PlaygroundSupport
import SwiftUI
struct ContentView: View {
@State private var isDragging = false
@State private var dragOffset: CGSize = .zero
@State var position: CGSize = .zero
@State private var hovered = false
var body: some View {
RoundedRectangle(cornerRadius: 20)
.foregroundColor(.red)
.frame(width: 100, height: 100)
.position(x: 400, y: 350)
RoundedRectangle(cornerRadius: 20)
.foregroundColor(.blue)
.frame(width: 100, height: 100)
.position(x: 400, y: 350)
.animation(.default, value: hovered)
.offset(x: dragOffset.width + position.width, y: dragOffset.height + position.height)
.gesture(
DragGesture()
.onChanged({ value in
self.dragOffset = value.translation
})
.onEnded({ value in
self.position.width += value.translation.width
self.position.height += value.translation.height
self.dragOffset = .zero
})
)
}
}
PlaygroundPage.current.setLiveView(ContentView())
If anyone knows how to do this, please help me.
