feat: comprehensive rewrite — push-to-talk pipeline, Typeless UI, Chinese
This is a major rewrite of OpenLessKeyboard, renamed to OSGKeyboard
and rebuilt end-to-end. 59 files changed (+3205/-1550).
Architecture
------------
- Rename project, targets, directories from OpenLess* to OSGKeyboard*
(OpenLess / OpenLessKeyboard / OpenLessShared / OpenLessTests).
- AudioCaptureService rewritten as @unchecked Sendable class with
OSAllocatedUnfairLock instead of an actor, so it survives Swift 6
strict-concurrency checks while still serialising engine + converter
state correctly.
- Single design system (Palette / Spacing / Radius / TypeStyle /
Motion) lifted into OSGKeyboardShared so the host app and the
keyboard extension stay in lock-step.
Push-to-talk — first-principles fix
-----------------------------------
- App Group + audio-input entitlements were stripped by Xcode's
Automatic Signing. They are now declared in project.yml so
'xcodegen generate' re-emits them every time. iOS Developer
Account is untouched; only the App Group capability was added.
- State machine uses a real stored `phase` (was a derived shim
that locked out every press after the first because
recordStream was never nilled after the pipeline finished).
- Microphone permission is requested inside pressBegan (async
Task) so the press flow optimistically enters .recording;
permission denial surfaces a short error and returns to idle.
- Replaced LongPressGesture(0.15s) with a DragGesture +
TapGesture pair separated by pressArmed, so a single tap no
longer fires both onPressBegan and onTap simultaneously.
- Real RMS / peak level meter from the AVAudioEngine tap (was a
pseudo-random walk); the visible waveform is now driven by
actual audio.
- SFSpeechRecognizer(locale:) with selectable ASR locales
(auto / zh-Hans / zh-Hant / en-US / ja-JP / ko-KR) for
first-class Chinese / English / Japanese / Korean dictation,
with on-device recognition when supported.
- AVAudioSession now deactivates on stop so other apps' audio
routing is restored.
Keyboard UI — Typeless-inspired layout
---------------------------------------
- Hero area is 280 pt with a 96 pt record disc, breathing outer
ring, and a 12-bar waveform driven by the real RMS.
- inputView.allowsSelfSizing + a heightAnchor constraint so iOS
no longer crops the keyboard under the Spotlight bar / home
indicator.
- Top bar: mode chip (Off / 转写 / 润色) + locale chip
(Auto / 简体 / 繁體 / EN / 日 / 한) + status badge + ⚙.
- Bottom bar: globe / delete / 空格 / return — all 40 pt and
balanced.
- RecordButton onPressEnded is now safe to fire from a quick
press; pressArmed prevents double-firing.
LLM / Polishing
---------------
- LLMClient: stopped leaking the server response body in errors
(server body is now logged at debug, never surfaced to UI);
added a dedicated .rateLimited case for 429.
- PolishingService timeout 8s → 12s to accommodate slower
domestic LLM providers.
- AppGroupStore.defaultSystemPrompt is now provider-aware
(Chinese for zhipu/moonshot/qwen/deepseek, English otherwise).
Onboarding & Settings
---------------------
- Re-themed OnboardingView / HomeView / SettingsView on the
new design system.
- ProviderPickerSection now shows 6 providers (OpenAI, DeepSeek,
Qwen DashScope, 智谱 GLM, 月之暗面 Moonshot, Custom) with
blurb + selected accent.
- PickerRow for Mode and ASR locale; System Prompt editor with
reset-to-default.
- API settings page "Get an API key" used SwiftUI Link, which
has a hit-test bug on iOS 18 that ate gestures from adjacent
TextFields (manifested as "typing jumps to a website"). It is
now an explicit Button + contentShape + .submitLabel(.done) on
the fields.
Polish & tests
--------------
- LLMClientTests: 4 unit tests passing (ProviderConfig
persistence + OpenAI request/response + HTTP error + missing
key); test App Group renamed to the correct identifier.
- ProviderConfig.apply now captures the previous provider id
*before* mutating, so switching providers actually resets the
system prompt to the new default.
Build
-----
- Swift 6 strict concurrency, iOS 18.0 deployment target.
- Tested on Xcode 26 + iPhone 17 Pro simulator. A real device on
iOS 27 beta aborts with __abort_with_payload (dispatch
library ABI mismatch); use an iOS 18 real device or the
iOS 26 simulator for now.

// Principal class for the Custom Keyboard Extension. Hosts a single

// AudioCaptureService ──► ASRService ──► PolishingService ──► insertText
|

//
|
||||
// Design notes:
|
||||
// • The class is `@MainActor` — every UI mutation and `textDocumentProxy`
|
||||
// call must happen on main, and Swift 6 strict concurrency forces this.
|
||||
// • State is a single `State` ObservableObject; SwiftUI observes it via
|
||||
// `@ObservedObject` so we never re-create the hosting root on each tick.
|
||||
// • `phase` is a real stored property (no derivation) — the previous
|
||||
// "derive from recordStream" shim locked out every press after the first.
|
||||
// • Microphone permission is requested *inside* pressBegan, but we still
|
||||
// start the rest of the press flow optimistically; if permission is
|
||||
// denied we surface a short error and drop back to idle cleanly.
