VerificationCodeInputField: iPad Return key clears/hides OTP fields #1407
Description
Environment:
- Swift, iPadOS version: all, FirebaseUI version: do not know exactly (Podfile.lock), Xcode: found it while testing
Steps:
- Present view using VerificationCodeInputField (e.g. PhoneReauthView)
- Focus OTP field on iPad with hardware keyboard
- Press Return repeatedly
Observed: fields disappear one-by-one, unrecoverable without back+Verify
Expected: Return resigns/dismisses or no-ops, fields stay visible
Relevant: FirebaseSwiftUI/FirebaseAuthUIComponents/Sources/Components/VerificationCodeInputField.swift - BackspaceAwareTextField.Coordinator has no textFieldShouldReturn, shouldChangeCharactersIn only blocks non-digits but Return path can hit handleBackspace/clear.

Hi @amansingh1207 , thanks for raising this. I see you've created a PR to fix this issue, I'll review that and keep this issue updated.

Thanks @demolaf for taking a look!
The PR #1408 fixes VerificationCodeInputField so iPad hardware Return just resigns focus (textFieldShouldReturn → resignFirstResponder + return false) instead of mutating/clearing digit fields. I also removed the newline guard so pasting codes with trailing \n (from SMS/email) still works — the existing digitsOnly filter already blocks lone Return presses.
Happy to add a UI test for this in a follow-up PR.
Looking forward to your feedback!

Hi @amansingh1207, I couldn't reproduce this on
main(iPad simulator, hardware keyboard, sign-in andPhoneReauthView): Return only reachestextFieldShouldReturnand never clears the fields.Can you still reproduce it consistently? If so, please share your FirebaseUI and iPadOS versions, keyboard setup, and a short screen recording.

Hi @demolaf,
The UI test failure (testSignInDisplaysSignedInView in FirebaseSwiftUIExampleUITests) is unrelated to this PR — my change only touches VerificationCodeInputField.swift (added textFieldShouldReturn + returnKeyType = .done), which is used in phone OTP flows, not the sign-in/sign-out path in that test.
Looks like a flaky/pre-existing e2e issue (likely emulator/auth-timing related). Could we re-run the UI workflow? If it keeps failing, happy to look into it or add a focused UI test for OTP Return behavior separately.
Actually currently I do not have access of mac and iPad that is why I am unable to build it and test it.
Thanks!

Thanks @amansingh1207. Since this wasn't observed on a device and Return never reaches the clearing path on
main(verified on iPad with a hardware keyboard in both sign-in andPhoneReauthView), I'll close this as not reproducible along with #1408. Please reopen with a screen recording if you hit it on real hardware.amansingh1207 commentedon Nov 2, 2026

Thanks @amansingh1207, the recording helps. It shows the legacy UIKit phone UI (
FUICodeField), where the on-screen keyboard's Return key inserts a newline into the code and removes a dash each time.That component was removed in v16.0.0, so it isn't the SwiftUI
VerificationCodeInputFieldthat #1408 changes.Versions below v16 are no longer maintained, so we won't be shipping a fix for them.
Please upgrade to v16 (FirebaseUI SwiftUI), where this doesn't occur, and if you can still reproduce it there, share your FirebaseUI and iPadOS versions plus a minimal sample project and we'll take another look.
