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

我得到的最接近的是创建一个ClearButton ViewModifier并将其添加到TextFieldusing.modifer()

唯一的问题是ClearButton永久性的，TextField取消选择时不会消失

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

struct ClearButton: ViewModifier {
    @Binding var text: String

    public func body(content: Content) -> some View {
        HStack {
            content
            Button(action: {
                self.text = ""
            }) {
                Image(systemName: "multiply.circle.fill")
                    .foregroundColor(.secondary)
            }
        }
    }
}
