Replaces and forward-ports #210 onto the current iOS glass composer. The original contributor remains the commit author.

What changed

  • adds on-device speech dictation beside Send in the iOS companion
  • streams partial text into the editable composer without stacking duplicates
  • stops capture on backgrounding, interruptions, navigation, sheets, send, and the plus menu
  • adds bounded locale selection, permission messaging, usage descriptions, tests, and docs
  • preserves the current chat redesign instead of restoring stale UI from the conflicted branch

Review fixes

  • explicitly imports Combine for the observable speech controller
  • scopes expected Speech cancellation codes to the correct error domain
  • cancels an in-flight permission request before a message can send

Verification

  • xcrun swift test — 135 tests, 0 failures
  • generated Xcode project + unsigned generic iOS Simulator build — succeeded
  • git diff --check

Closes #210 after this replacement lands.

Summary by CodeRabbit

  • New Features

    • Added tap-to-talk dictation to the iOS composer with partial transcript updates.
    • Supports starting and stopping recording, editing dictated text, and appending speech to existing drafts.
    • Added on-device speech recognition with locale selection and English fallback.
    • Displays permission prompts and user-facing dictation errors.
  • Bug Fixes

    • Dictation now stops safely when submitting, navigating, locking, backgrounding, or encountering audio interruptions.
  • Documentation

    • Updated iOS documentation and verification steps for composer dictation.

📝 Walkthrough

Walkthrough

Adds on-device speech dictation to the iOS chat composer. It supports partial transcripts, locale selection, permissions, lifecycle cleanup, microphone controls, draft editing, tests, and documentation.

Changes

Composer dictation

Layer / File(s) Summary
Dictation composition and locale contracts
ios/Sources/CompanionCore/Dictation.swift, ios/Tests/CompanionCoreTests/DictationTests.swift
Adds draft composition and locale candidate utilities. Tests cover partial replacement, whitespace handling, deduplication, canonicalization, and English fallback.
Speech capture lifecycle
ios/App/SpeechDictation.swift
Adds permission handling, audio capture, partial recognition, on-device recognition when supported, cancellation protection, interruption handling, and teardown.
Composer integration and verification
ios/App/ChatView.swift, ios/project.yml, ios/TESTING.md, ios/README.md
Adds microphone controls, listening state, transcript updates, submission cleanup, lifecycle cleanup, permission descriptions, documentation, and Stage 4 verification steps.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to feefc

The PR adds iOS dictation, but the current head still has a test-compilation blocker: a test uses try XCTUnwrap without declaring throws. Until corrected or explicitly accepted, the PR is not merge-ready.

In `@ios/App/ChatView.swift`:
- Around line 256-283: Update the dictation lifecycle handlers around
showingComputer, showingTasks, showingProfile, and the room-chat header’s
showingPlus state so dictation.stop() is called whenever showingPlus becomes
true. Preserve the existing behavior for the other presentation states.
- Around line 596-607: Update SpeechDictation.start to publish a startup state
before freezing base, clear composerFocused when startup begins, and use that
state alongside isListening to disable the draft field and prevent edits until
dictation is ready or stops. Ensure the first partial transcript cannot
overwrite edits made during startup.

In `@ios/Sources/CompanionCore/Dictation.swift`:
- Around line 52-53: Limit the languages added by localeCandidates to an
explicit maximum, stopping once that bound is reached so
SpeechDictation.beginCapture never constructs recognizers for an unbounded
preference list. Add or update tests to verify the candidate list is capped
while preserving the existing ordering of preferred languages.

609-628: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Reflect the starting state in the microphone button.

toggle(capturing:) stops dictation when isStarting is true. The icon and the accessibility label use only isListening, so during the permission window the button announces "Start dictation" while the tap stops dictation. Screen reader users get the wrong action name.

- Around line 212-219: Update the cancellation check in the recognition-error
handling flow around recognitionError and stop() to map cancellation codes by
error domain: retain only 209 and 216 for kLSRErrorDomain, and handle
kAFAssistantErrorDomain separately with its valid cancellation codes, excluding
1110 because it represents no speech detected. Preserve stop() and the early
return only for genuine cancellations.

In `@ios/Tests/CompanionCoreTests/DictationTests.swift`:
- Around line 74-81: Declare
testEnglishIsTheLastResortWhenNothingElseIsOffered() as throws so its try
XCTUnwrap(locales.last) call compiles.
