Random Image when pressing a button in SwiftUI

I'm trying to make a random image appear on the screen, when I am pressing a button. I have three images which I want to be randomly shown, when I press the button. How do I do this?

Solution

  • If you are using an Array you can use the .randomElement(). Here's a simple example using the symbols from SF Symbols.

    struct RandomImage: View {

@State var random: String = ""

var body: some View {
    VStack {

        Image(systemName: random)

        Button(action: {
            self.random = chooseRandomImage()
        }) {
            Text("Another one!")
        }

    }


}
}

var images = ["sun.max.fill", "moon.fill", "star.fill"]

func chooseRandomImage() -> String {
    let array = images

    let result = array.randomElement()!

    return result
}
