+# Fastlane – App-Store-Screenshots & Upload
+
+iOS-Gegenstück zu `android/fastlane`. Die App muss dafür **nicht** neu gebaut
+werden – der Demo-Modus (`demo@`-Login) liefert die kompletten Inhalte aus
+Fixtures.
+
+## 1. Screenshots aufnehmen
+
+Aus dem **Client**-Wurzelverzeichnis:
+
+```bash
+tool/screenshots_ios.sh
+```
+
+Fährt „iPhone 14 Plus“ (6,5″, 1284×2778) und „iPad Pro 13-inch (M5)“
+(13″, 2064×2752) nacheinander durch und legt die PNGs in
+`materials/screenshots/{ios/6-5-inch,ipados/13-inch}/` sowie als JPEG-Upload-Kopie
+(App Store Connect lehnt Alpha-Kanäle ab) in `screenshots/de-DE/` ab. Fehlende
+Simulatoren legt das Skript selbst an.
+
+- Nur eine Größe: `PROFILES="iphone" tool/screenshots_ios.sh`
+- Andere Simulatoren: `IPHONE_SIM="iPhone 11 Pro Max" IPAD_SIM="…" tool/screenshots_ios.sh`
+
+App und Schlüsselbund der verwendeten Simulatoren werden dabei zurückgesetzt.
+
+## 2. Hochladen
+
+fastlane installieren (`brew install fastlane`), in App Store Connect unter
+*Benutzer und Zugriff → Integrationen → App Store Connect API* einen Key mit
+Rolle *App-Manager* anlegen und als JSON ablegen:
+
+```json
+{
+  "key_id": "ABC123XYZ",
+  "issuer_id": "00000000-0000-0000-0000-000000000000",

+```
+
+```bash
+export APP_STORE_CONNECT_API_KEY=/pfad/zu/app-store-connect-api-key.json
+cd ios
+fastlane upload_screenshots
+```
+
+Die Screenshots landen in der aktuell bearbeitbaren App-Store-Version
+(„Vorbereitung für Einreichung“); vorhandene Screenshots werden ersetzt. Der
+API-Key wird **nicht** eingecheckt (siehe `.gitignore`).

Fixed the demo router answering timetable/custom-events with a week, which crashed the inline iOS widget refresh after a demo login.

MineTecandClaude Fable 5.1	279b973e89	hardened API decoding against server fields the models did not expect The Talk room list crashed for a new account because the server omits lastMessage for rooms without a visible message and the model required it. Beyond that single field, a review of the Talk models against the OpenAPI spec of the installed version (23.0.8) found the same crash class in several places: closed enums over open server values (inCall bitmask, rich-object types, actor and message types), a deleted parent sent as {id, deleted}, and the autocomplete status arriving as an object. - json_serializable `checked: true`: decode errors now name class and field - lists (rooms, messages, participants, autocomplete) decode per entry; a malformed entry is skipped and reported via ClientErrorReporter - unknownEnumValue fallbacks for all response enums of Talk and breakers - lastMessage nullable; inCall as bitmask; deleted parent placeholder; autocomplete status object/string; fixed shareWithDisplayNameUnique key - GetRoomParams no longer sends null query parameters Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HrepDTL4qDe35TuS29sLW3	2026-09-29 16:35:41 +02:00
