swiftUI how to disabled a button for 2sec? - button

Question

i have a bug, if i click on button before the animation before the card flip back. i think for me the best it would be to disable the button for 2 sec, but i made some research and didnt find anything!
struct CardBack: View {
var body: some View {
Image("back_card")
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 250)
}
}
struct ContentView: View {
#State var flipped = false
#State private var cardsFront = ["bigCard1", "bigCard2", "bigCard3", "bigCard4", "bigCard5" ]
#State private var cardBack = "back_card"
#State private var disablled = true
var body: some View {
VStack {
Spacer()
ZStack {
Image(flipped ? self.cardsFront.randomElement()! : self.cardBack)
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 250)
.rotation3DEffect(Angle(degrees: flipped ? 180 : 0 ), axis: (x: 0, y: 1, z: 0))
}
Spacer()
HStack {
Button(action: {
withAnimation(.spring()) {
self.flipped.toggle()
}
DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
withAnimation(.spring()) {
self.flipped.toggle()
}
}
}) {
Image("circle")
.renderingMode(.original)
}
Button(action: {
}) {
Image("plus")
.renderingMode(.original)
}

You can set the button as disabled initially and then enable it using the same sort of logic I used here.
import SwiftUI
struct ContentView: View {
#State var changeColor = false
var body: some View {
TextView(changeColor: $changeColor)
}
}
struct TextView: View {
#Binding var changeColor: Bool
var body: some View {
Text("Hello World")
.foregroundColor(changeColor ? Color.black: Color.red)
.onAppear {
DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
self.changeColor.toggle()
}
}
}
}
You are almost there, you just need to use the .appear tag in your code to do this.
