SecureField(String("Password"), text: $pass).padding(.all).border(Color.white).cornerRadius(3.0).padding(.horizontal)

推荐答案

在下面的演示中找到一些可能的方法.也可能值得考虑在 UITextField 周围使用可表示性，因为它更具可配置性.

Find below a demo of some possible approach. Also might worth considering representable around UITextField as it is much more configurable.

通过Xcode 11.7/iOS 13.7测试

Tested with Xcode 11.7 / iOS 13.7

struct PlaceholderTextFieldStyle: TextFieldStyle {
    let placeholder: String
    @Binding var text: String

    init(_ placeholder: String, text: Binding<String>) {
        self.placeholder = placeholder
        self._text = text
    }

    func _body(configuration: TextField<Self._Label>) -> some View {
        ZStack {
            if text.isEmpty {
                Text(placeholder)
            }
            configuration
        }.foregroundColor(.white)
    }
}

struct DemoView: View {
    @State private var pass = ""

    var body: some View {
        SecureField("", text: $pass)
        .textFieldStyle(PlaceholderTextFieldStyle("Password", text: $pass))
        .padding(.all).border(Color.white).cornerRadius(3.0).padding(.horizontal)
        .padding()
        .background(Color.blue)

    }
}
