SwiftUI text field with 4 border types (DEFAULT, NO_BORDER, ONLY_BOTTOM, NO_PADDING), secure/password mode, disabled state, placeholder styling, and real-time text change handler. Mirrors the UIKit TTBaseUITextField API in SwiftUI idiom.

🎨 Types

public enum TYPE {
    case DEFAULT      // Rounded rect border
    case NO_BORDER    // No visible border
    case ONLY_BOTTOM  // Bottom underline only

}

Type	Appearance	Use Case

.NO_BORDER	No border	Fields inside custom containers
.ONLY_BOTTOM	Bottom line	Flat/modern style
.NO_PADDING	Minimal	Tight layouts
