SecureTextFiledForSwiftUI

This is a sample application of SwiftUI that
switches the input-form of the secure password to the form
that can confirm the entered character string by tapping the eye button.

Point of this sample

The point is to separate SecureField or TextField according to the bound Bool value (isSecured).
isSecured can be switched by tapping the eye button.
We can use SF Symbols for the eye and slash-eye icon images.

struct PasswordView: View {

    @State private var password: String = ""
    @State private var isSecured: Bool = true

    var body: some View {
        HStack {
            if self.isSecured {
                SecureField("Password", text: $password)
                    .textFieldStyle(RoundedBorderTextFieldStyle())
                    .padding(.leading, 20.0)
            } else {
                TextField("Password", text: $password)
                    .textFieldStyle(RoundedBorderTextFieldStyle())
                    .padding(.leading, 20.0)
            }
            Button(action: {
                self.isSecured.toggle()
            }) {
                self.isSecured ?
                    Image(systemName: "eye.slash.fill") :
                    Image(systemName: "eye.fill")
            }
            .foregroundColor(.gray)
            .padding(.trailing, 20.0)
        }
    }
}
