In code it would look like this:
import SwiftUI
import PlaygroundSupport
struct MyTextView: View {
@State private var text1: String = "Some Content"
@State private var text1Placeholder: String = ""
@State private var text2: String = ""
var body: some View {
VStack(alignment: HorizontalAlignment.center, spacing: 20) {
Image(systemName: "circle")
TextField( self.$text1Placeholder.wrappedValue, text: $text1, onEditingChanged: { (editing) in
if editing {
self.$text1Placeholder.wrappedValue
= self.$text1.wrappedValue
self.$text1.wrappedValue = ""
}
})
TextField("Text Field 2", text: $text2)
.border(Color.green)
}.padding()
}
}
PlaygroundPage.current.liveView = UIHostingController(rootView: MyTextView())
The onEditingChange parameter take a closure with a single Bool parameter, if it is true then the TextField has begun to edit the parameter. In your closure check the value of the parameter and clear the TextField variable if it is true.
