SwiftUI Modern Animated OTP Input Pattern
SwiftUI guide for creating animated OTP verification inputs with validation states
This tutorial demonstrates how to build a clean, animated one-time password (OTP) verification screen in SwiftUI. It covers creating individual digit input boxes with advancing carets, a floating particle centerpiece, and visual validation states for success and failure. It serves as a practical pattern for enhancing authentication flows in iOS apps.
How it works
SwiftUI tutorial for a modern OTP input with animation and validation. The demo UI: dark card with 'Enter the code' heading, helper text 'We sent you a code to your email, please enter to verify your address.', four rounded code input boxes with a caret that advances as digits are typed, an animated sphere of floating scattered digits as the visual centerpiece, pink/red outlines on the boxes when validation fails (code entered: 4785 rejected, then retried), and a green outline with checkmark indicating successful verification.
What it's for
- Build a verification code screen for iOS onboarding or authentication flows
- Add error and success feedback animations to text input fields
- Implement synchronized caret movement across multi-box passcode inputs
Key points
- Multi-box code entry with auto-advancing cursor states
- Visual error states with red/pink outlines upon failed validation
- Success confirmation styling with green accents and checkmark indicators
- Animated floating digit graphic used as an interface centerpiece
- Clean dark-mode aesthetic with accessible helper copy
