From aeb28f4b361ff2a116262c68bae2db5367793727 Mon Sep 17 00:00:00 2001 From: Rocky <72559939+hkgood@users.noreply.github.com> Date: Thu, 18 Jun 2026 19:34:53 +0800 Subject: [PATCH] fix: green accent + real iOS ASR in preview + bilingual audit MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three user-flagged fixes, scoped tightly to the files each affects. The uncommitted Engine-mode wiring / locale picker / etc. from a prior agent pass is intentionally not included in this commit. 1. Revert accent to brand green (#3AA05A). Last commit flipped `AccentColor` + `Palette.light.accent` to Apple system blue (#007AFF) on the assumption that "green CTA on a near-white surface looks wrong." Review pushed back: the brand *is* the green, and the system tint should match it so that NavStack Done buttons, Toggles, and our custom `primaryButton()` modifier all read as the same colour. Restored `#3AA05A` in both `AccentColor.colorset/Contents.json` and `Palette.light.accent` (plus the muted / glow variants). 2. Real iOS ASR in `KeyboardPreviewSheet`. The previous fix only swapped the static placeholder for a `TextField` and routed a hardcoded stub through it — review asked, fairly, "are you actually calling `SFSpeechRecognizer`?" Answer: no. This change makes the preview *run real ASR*: - `ASRService` (+ the iOS 26 `SpeechAnalyzer` path) moves from `OSGKeyboardExt/Services/` to `OSGKeyboardShared/Services/`, so the host app can import the same `ASRServiceFactory.make()` the keyboard extension uses. - `OSGKeyboardShared` gains `Speech.framework` and `AVFoundation.framework` as SDK dependencies in `project.yml`. - New `OSGKeyboard/Views/PreviewASRController.swift` (the extension's `AudioCaptureService` is app-extension-only, so the preview owns its own `AVAudioEngine` + `AVAudioSession` and downsamples to 16 kHz mono Float32 via `AVAudioConverter`). - `KeyboardPreviewSheet.cyclePhase()` now calls `asr.start(locale:)` / `asr.stop()` instead of toggling a `StubPhase`. The disc's level meter is driven by RMS from the actual audio tap; the transcript line under the chips shows the live `SFSpeechRecognizer` partial; the top textbox receives the `.final` transcript via `onChange(of: lastFinal)`. 3. Record disc in BOTH stubs now uses the green accent for idle. Was `Color(white: 0.22)` dark-gray, which read as "inert surface" rather than "tap me". The keyboard extension and the in-app preview now share the same brand-green disc gradient so the keyboard's primary CTA is the same colour in both modes. 4. Bilingual audit across every user-facing string. Every Text() in the main-app and extension views is now `中文 · English` or carries an English secondary line. Covered: - OnboardingView (Back, Next, Done, Continue, step instructions, PrivacyFootnote rows) - HomeView (status header, hero label, accessibility) - APISettingsCard (Base URL, API Key, Model, "Get an API key", "Connection", test-connection states + error messages) - KeyboardPreviewSheet (title, subtitle, TextField placeholder, clear button accessibility) - KeyboardPreviewStub (mode/locale chips, REC badge, space bar) - KeyboardRootView (gear accessibility, space bar, requesting state, denied messages, local-engine chip) - RecordButton (accessibility label) - SettingsView (Done, Reset dialog, language section subtitle, engine section, local-engine subtitle, on-device label) - AppGroupErrorView (title, body, three remediation steps) - LLMProvider preset names and blurbs Where the prior pattern was "Chinese headline + English footnote" (e.g. OnboardingView's 启用 OSGKeyboard / Enable OSGKeyboard), that pattern was preserved — bilingual coverage means every screen reads as both, not that every line is rigidly `中 · EN`. Build: BUILD SUCCEEDED on iPhone 17 Pro / iOS 26 simulator. Tests: 21/21 pass (no test changes). Visual: light-mode home shot at /tmp/osgk_light_green.png shows the brand-green CTA restored across Next button, mic icon, and page dot. 🤖 Generated with Claude Code --- .../AccentColor.colorset/Contents.json | 6 +- OSGKeyboard/Views/APISettingsCard.swift | 28 +- OSGKeyboard/Views/AppGroupErrorView.swift | 11 +- OSGKeyboard/Views/HomeView.swift | 6 +- OSGKeyboard/Views/KeyboardPreviewSheet.swift | 157 +++++---- OSGKeyboard/Views/KeyboardPreviewStub.swift | 59 +++- OSGKeyboard/Views/OnboardingView.swift | 24 +- OSGKeyboard/Views/PreviewASRController.swift | 272 +++++++++++++++ OSGKeyboard/Views/SettingsView.swift | 306 +++++++++++++++-- OSGKeyboardExt/Services/ASRService.swift | 166 --------- OSGKeyboardExt/Views/KeyboardRootView.swift | 49 ++- OSGKeyboardExt/Views/RecordButton.swift | 11 +- OSGKeyboardShared/DesignSystem/Theme.swift | 21 +- OSGKeyboardShared/Models/LLMProvider.swift | 16 +- OSGKeyboardShared/Services/ASRService.swift | 317 ++++++++++++++++++ project.yml | 21 +- 16 files changed, 1117 insertions(+), 353 deletions(-) create mode 100644 OSGKeyboard/Views/PreviewASRController.swift delete mode 100644 OSGKeyboardExt/Services/ASRService.swift create mode 100644 OSGKeyboardShared/Services/ASRService.swift diff --git a/OSGKeyboard/Assets.xcassets/AccentColor.colorset/Contents.json b/OSGKeyboard/Assets.xcassets/AccentColor.colorset/Contents.json index 5fc45de..cc28362 100644 --- a/OSGKeyboard/Assets.xcassets/AccentColor.colorset/Contents.json +++ b/OSGKeyboard/Assets.xcassets/AccentColor.colorset/Contents.json @@ -5,9 +5,9 @@ "color-space" : "srgb", "components" : { "alpha" : "1.000", - "blue" : "1.000", - "green" : "0.478", - "red" : "0.000" + "blue" : "0.353", + "green" : "0.627", + "red" : "0.227" } }, "idiom" : "universal" diff --git a/OSGKeyboard/Views/APISettingsCard.swift b/OSGKeyboard/Views/APISettingsCard.swift index f2ddd95..b4ff9b5 100644 --- a/OSGKeyboard/Views/APISettingsCard.swift +++ b/OSGKeyboard/Views/APISettingsCard.swift @@ -24,7 +24,7 @@ struct APISettingsCard: View { var body: some View { VStack(spacing: 0) { field( - title: "Base URL", + title: "Base URL · 接口地址", placeholder: "https://api.openai.com/v1", text: $config.baseURL, autocap: false @@ -33,7 +33,7 @@ struct APISettingsCard: View { keyField Divider().background(palette.divider) field( - title: "Model", + title: "Model · 模型", placeholder: "gpt-4o-mini", text: $config.model, autocap: false @@ -50,7 +50,7 @@ struct APISettingsCard: View { HStack { Image(systemName: "key.fill") .foregroundStyle(palette.accent) - Text("Get an API key") + Text("获取 API Key · Get an API key") .foregroundStyle(palette.textPrimary) Spacer() Image(systemName: "arrow.up.right.square") @@ -77,7 +77,7 @@ struct APISettingsCard: View { private var keyField: some View { VStack(alignment: .leading, spacing: 6) { HStack { - Text("API Key") + Text("API Key · 密钥") .font(TypeStyle.caption) .foregroundStyle(palette.textSecondary) Spacer() @@ -86,7 +86,7 @@ struct APISettingsCard: View { .foregroundStyle(palette.textSecondary) } .buttonStyle(.plain) - .accessibilityLabel(Text(showKey ?
