SecureField สำหรับรหัสผ่าน

Passwords should never appear on screen as plain letters. SwiftUI gives you SecureField, a text field that masks every character. 🔒

A SecureField works exactly like a TextField: a placeholder and a binding. The only difference is the dots shown instead of the real characters.

Just like before, the typed value lives in a @State string. SecureField reads and writes it through the binding you pass with the $ prefix.

The dots are only for display. Your state string holds the actual text, so you can validate or send it even though the screen hides it.

Give it the same polish as any field. The textFieldStyle modifier with .roundedBorder makes a clean, tappable password box.

A login screen usually stacks a normal TextField for the email above a SecureField for the password, each with its own state.

Add textContentType(.password) so iOS offers saved passwords and Keychain suggestions, making sign-in faster for your users.

On a sign-up screen use .newPassword instead. iOS then suggests a strong, unique password and stores it in the Keychain.

SecureField supports onSubmit too. When the user taps return, run your login or move focus to the next field.

Because the characters are masked, no one glancing at the screen sees the password. SecureField gives you that privacy for free.

Everything you learned about binding text still applies. SecureField is simply the safe choice whenever the input is a secret. ✨

You masked secret input with SecureField, kept the real value in state, and used textContentType to help iOS suggest and save passwords. 🎉
