code:
import SwiftUI
struct practise: View {
@State var value = false
var body: some View {
Text("Hello, World!")
}
}
struct practise_Previews: PreviewProvider {
static var previews: some View {
practise()
}
}
func changevalue(){
//Change Value here
}
How am I able to change the value of 'value', within the change value() function.
Create a button in Practice View calling changeValue.
struct Practise: View {
@State var value = false
func changeValue(){
// Change Value here
value = !value // we toggle
// could call as well: value.toggle()
}
var body: some View {
Text("Hello, World! \(String(value))")
Button(action: changeValue) {
Text("Change")
}
}
}
struct practise_Previews: PreviewProvider {
static var previews: some View {
Practise()
}
}
