SwiftUI question

Hello folks,

I have a very simple SwiftUI question. Here’s what I want to do:

  1. When the app launches, my view is filled with an image.
  2. There is a button.
  3. When I tap the button, I want the image to change.
  4. I want the image to toggle at each tap of the button.

I have only been partially successful.



Hi Nagar,

Try this out.

struct ContentView: View {
    @State private var toggleImage = false
    var body: some View {
        VStack(spacing: 40) {
            Image(systemName: toggleImage ? "person" : "person.fill")
                .frame(width: 300, height: 300)
                .foregroundColor(toggleImage ? .blue : .red)
            Button(action: {
            }, label: {
                Text("Toggle Image")

Thanx Chris. Appreciate the quick response.

No problem.

Does that all make sense?

By the way, the Button can also be done this way:

Button(action: {
}) {
    Text(toggleImage ? "Change Back" : "Change Image")

Yes it does - thanx Chris!

Because that piece of code is inside a closure which means that it affects the scope of a variable declared outside of it. Using self tells the compiler that the variable is owned by the parent.
