SwiftUI: Add ClearButton to TextField

Question

I am trying to add a ClearButton to TextField in SwiftUI when the particular TextField is selected.

The closest I got was creating a ClearButton ViewM

Answer 1

Use ZStack to position the clear button appear inside the TextField.

TextField("Some Text" , text: $someBinding).modifier(ClearButton(text: $someBinding))

struct ClearButton: ViewModifier
{
    @Binding var text: String

    public func body(content: Content) -> some View
    {
        ZStack(alignment: .trailing)
        {
            content

            if !text.isEmpty
            {
                Button(action:
                {
                    self.text = ""
                })
                {
                    Image(systemName: "delete.left")
                        .foregroundColor(Color(UIColor.opaqueSeparator))
                }
                .padding(.trailing, 8)
            }
        }
    }
}
