How to Create Password TextField in iOS SwiftUI

Security is a fundamental aspect of modern applications, and protecting user credentials is paramount. SwiftUI provides a way to create password text fields that ensure the privacy of user input.

This blog post will guide you through creating a secure password text field in SwiftUI.

Password TextField in SwiftUI

In SwiftUI, the SecureField is specifically designed to handle password inputs. When a user types into a SecureField, the characters are obscured, typically with dots or asterisks, to protect the information from prying eyes.

Here’s an example of how you can create a SecureField:

struct ContentView: View {
    @State private var password = ""

    var body: some View {
        SecureField("Enter password", text: $password)
            .padding()
    }
}

Code Explanation

@State Property Wrapper

The @State property wrapper is used to declare a private variable called password. It stores the user’s password and triggers the view to update when the password changes.

SecureField

The SecureField is created with a placeholder "Enter password" and is bound to the password state variable. The user’s input is automatically obscured.

padding Modifier

Padding is added to provide space around the SecureField, enhancing its appearance.

Handling passwords securely is a critical part of app development, and SwiftUI’s SecureField makes it simple to create an input field designed explicitly for this purpose.

By obscuring the user’s input and allowing for further customization, you can provide a secure and user-friendly way for users to enter their passwords in your app.
