SwiftUI. How to change the placeholder color of the TextField?

Question

I want to change the placeholder color of the TextField, but I can\'t find a method for it.

I tried to set foregroundColor and accentColor,

It's a bit modification for the @jfk's answer, we can create an extension for view to simplify the modifier code inside the main view and also it can be used for Text and Image.

struct PlaceHolder: ViewModifier {
    var placeHolder: T
    var show: Bool
    func body(content: Content) -> some View {
        ZStack(alignment: .leading) {
            if show { placeHolder }
            content
        }
    }
}

extension View {
    func placeHolder(_ holder: T, show: Bool) -> some View {
        self.modifier(PlaceHolder(placeHolder:holder, show: show))
    }
}

Usage in TextField:

Add this line of code .placeHolder(Text("Your placeholder"), show: text.isEmpty) as a viewModifier to TextField.

TextField("", text: $text, onEditingChanged: { (changing) in
    print("Changing: \(changing)")
}, onCommit: {
    print("Committed!")
})
    .placeHolder(Text("Your placeholder"), show: text.isEmpty)

Usage in Image:

Further more, as @EmilioPelaez suggested, I modified the code to support placeholder for any view for ex. Image like below.

Image("your_image")
    .placeHolder(Image("placeholder_image"), show: true)
