Summary

Adds Afrikaans from South Africa as the ninth learning language, following the module pattern from #15.

  • New apps/ios/Core/Languages/Afrikaans.swift (af, af-ZA): greeting, speech/writing/lemma guidance, six teaching stages, and five South African theme overrides ('n Koffie?, By die mark, Op pad, 'n Naweek weg, Om die braai).
  • Afrikaans available as a subtitle language.
  • Detector alias: Apple's NLLanguageRecognizer has no Afrikaans class and labels Afrikaans transcripts as Dutch. LanguageModule gains an optional detectorAliases list (default empty, no change for existing modules) and a new TeachingPolicy.detectedMatchesTarget uses it, so a learner speaking Afrikaans is never redirected. The voice prompt separately tells the model not to drift into Dutch. The language-flow verification uses the same helper.
  • Android parity: scripts/export_android_content.py now recognises LanguageModule properties declared with a default and exports detectorAliases; the regenerated Languages.kt carries Afrikaans with its Dutch alias, and Kotlin's TeachingPolicy.shouldRedirectSpeech matches Swift by honouring aliases and regional suffixes. CoreTest gains the Afrikaans registry and redirect checks; the Play description lists Afrikaans.
  • API locale map and parity test updated (af-ZA accepted; bare af, nl-NL rejected).
  • README, language architecture, build guide, release notes and validation record updated.

Verification

  • swift test --package-path apps/ios (rebased onto the apps//services/ layout from Recover hosted sessions and add direct Android Stripe Managed Payments #22): 75 passed, 0 failures (Xcode 26.5) — registry order/locale/greeting, prompt isolation, nine-language archive round trip, Dutch detector IDs never redirect, 'n apostrophe word links.
  • Native UI tests on iPhone 17 / iOS 26.5 simulator: testAfrikaansOnboarding and testNewLanguageSettingsThemesWordsAndReturnToNorwegian passed.
  • services/api/tests/languages.test.ts passed.
  • Exporter tests (9), all 50 scripts/tests, and scripts/check_cross_platform.py passed; export_android_content.py --check is in sync.
  • Android unit tests were not run locally (no Java runtime on the build Mac); they run in CI.
  • Signed device build installed over an existing installation on an iPhone 15 Pro Max (iOS 26.5.2) and launched.
  • Live check: a real Afrikaans conversation on that iPhone with a saved key — speech, replies and subtitles worked well (owner listening check).

Limitations

OpenAI does not publish a GPT-Live language list and does not name Afrikaans; its guidance is that less common languages may have a non-native accent or fluency gaps. The automated --verify-audio --verify-language-flow --verify-language=af run and a fluent-speaker review of accent, corrections and Dutch drift are still required before any teaching-quality claim.

@kylemclaren kylemclaren changed the title Add Afrikaans learning Add Afrikaans (South Africa) Sep 14, 2026
Add an Afrikaans module (af, af-ZA) with South African theme overrides,
teaching stages, lemma and writing guidance, and Afrikaans as a subtitle
language. Apple's language recognizer has no Afrikaans class and reports
Afrikaans as Dutch, so LanguageModule gains an optional detectorAliases
list and TeachingPolicy.detectedMatchesTarget uses it, preventing speech
redirects for learners who are already speaking Afrikaans.

Extend the language-flow verification, coordinator sample, server locale
map and tests. 72 core tests, 2 native UI tests and the server locale
test pass; a live Afrikaans voice check is still outstanding.

The exporter now recognises LanguageModule properties declared with a
default value and emits the optional detectorAliases list, so Android's
generated Languages.kt carries Afrikaans with its Dutch alias. Kotlin's
shouldRedirectSpeech matches Swift by accepting aliases and regional
suffixes. Add the Afrikaans registry and redirect checks to CoreTest and
list Afrikaans in the Play description.
