Verify SwiftUI Screen

A hidden TextField with .oneTimeCode content type receives SMS autofill and keyboard input; the visible boxes mirror it. The active box shows a blinking caret, each digit lands with a small scale spring, and the row reports complete with a soft haptic once the last digit is in. Drive status from your verification: verifying dims the boxes under a spinner, success tints them green one by one with a success haptic, and error shakes the row, clears the digits last to first, and hands status back to idle with focus restored.

Notes

• States: entering, complete, verifying, success, error. status is a binding so the field can return .error to .idle after the clear; leave it .constant(.idle) if you only need entry.
• Paste is offered with the system PasteButton only when the clipboard holds a number, detected with UIPasteboard.detectPatterns, which never reads the contents or shows the paste banner. The pasted text is scanned for the first run of exactly length digits.
• VoiceOver focuses the real text field; its value reads the count and the entered digits, and its hint tracks the state. The boxes are hidden from VoiceOver.
• Reduce Motion keeps the caret solid and crossfades digits instead of scaling them.
• The screen reads the Graphic theme: an orange header block with a cropped dot matrix and a two-tone title, the number as a lemon block, and boxes that fill mint with dark digits through successColor and successInk.
• The resend block is disabled while its black dial counts down, then becomes a button; three misses ask for a new code, and the keyboard covers the bottom actions instead of pushing them over the boxes.
• CodeEntryExample at the end of CodeEntry.swift is the Verify screen from the preview.
