-# iOS Share Extension — Xcode Setup
-
-Die Quellen unter `ios/Share Extension/` müssen einmalig in Xcode als **Share Extension Target** verdrahtet werden — analog zur `TimetableWidgetExtension`. Erst danach taucht „Marianum Fulda" im System-Share-Sheet auf.
-
-## Schritt 1 — Share-Extension-Target anlegen
-
-1. `ios/Runner.xcworkspace` in Xcode öffnen.
-2. Projekt-Sidebar → `Runner` (Projekt-Root) → **+ Add Target** unten links.
-3. **iOS → Share Extension** wählen.
-4. Eigenschaften:
-   - Product Name: `Share Extension` (mit Leerzeichen, exakt so — der Ordnername und Podfile-Eintrag matchen).
-   - Bundle Identifier: `eu.mhsl.marianum.mobile.client.Share-Extension`.
-   - Language: Swift.
-   - Embed in: Runner.
-5. Beim Activate-Scheme-Dialog auf **Cancel** klicken.
-6. Deployment Target = mind. iOS 12.0 (Plugin-Mindestanforderung).
-
-## Schritt 2 — Vorhandene Quelldateien ins Target ziehen
-
-Xcode legt Dummy-Dateien an. Diese **löschen** (Move to Trash). Dann:
-
-1. Sidebar → Rechtsklick auf den Ordner `Share Extension` → **Add Files to "Runner"…**
-2. Im File-Picker zu `ios/Share Extension/` navigieren und folgende Dateien selektieren:
-   - `ShareViewController.swift`
-   - `Info.plist`
-   - `MainInterface.storyboard`
-   - `Share Extension.entitlements`
-3. **Wichtig**: bei „Add to targets" nur `Share Extension` ankreuzen, **nicht** Runner.
-
-## Schritt 3 — App Group aktivieren
-
-Beide Targets brauchen die App-Group-Berechtigung, damit die Extension geteilte Dateien für die Hauptapp im gemeinsamen Container ablegen kann.
-
-1. **Runner**-Target → **Signing & Capabilities** → **+ Capability** → **App Groups**.
-   - Group-ID hinzufügen: `group.eu.mhsl.marianum.mobile.client.share` (zusätzlich zur bereits existierenden Widget-Group).
-2. Dasselbe für **Share Extension**-Target — mit derselben Group-ID `group.eu.mhsl.marianum.mobile.client.share`.
-
-Im Apple-Developer-Portal muss diese App-Group bei beiden App-IDs eingetragen sein, sonst schlägt das Provisioning fehl.
-
-## Schritt 4 — User-Defined Build Setting `CUSTOM_GROUP_ID`
-
-Beide Targets brauchen das User-Defined Setting, das in `Runner/Info.plist` und `Share Extension/Info.plist` als `$(CUSTOM_GROUP_ID)` referenziert wird.
-
-1. **Runner** → Build Settings → `+` (oben links) → **Add User-Defined Setting**.
-   - Name: `CUSTOM_GROUP_ID`
-   - Wert: `group.eu.mhsl.marianum.mobile.client.share`
-2. Dasselbe für **Share Extension**-Target.
-
-## Schritt 5 — Entitlements verlinken
-
-1. **Runner** → Build Settings → `CODE_SIGN_ENTITLEMENTS` zeigt bereits auf `Runner/Runner.entitlements` (jetzt mit beiden Groups).
-2. **Share Extension** → Build Settings → `CODE_SIGN_ENTITLEMENTS` → auf `Share Extension/Share Extension.entitlements` setzen.
-
-## Schritt 6 — Info.plist-Pfad
-
-**Share Extension** → Build Settings → `INFOPLIST_FILE` → auf `Share Extension/Info.plist` setzen.
-
-## Schritt 7 — Build Phases reorder
-
-Damit das Plugin-Modul vom Extension-Target gefunden wird:
-
-1. **Runner**-Target → **Build Phases**.
-2. `Embed Foundation Extensions` per Drag-and-Drop **vor** `Thin Binary` ziehen.
-
-## Schritt 8 — Pods installieren
-
-```bash
-cd ios && pod install
-```
-
-Der Podfile-Eintrag (`target 'Share Extension' do inherit! :search_paths end`) ist bereits vorhanden.
-
-## Schritt 9 — Build & Run
-
-1. Scheme `Runner` wählen → Run auf Device oder Simulator (≥ iOS 12).
-2. Foto in der Fotos-App auswählen → Teilen → „Marianum Fulda" sollte erscheinen.
-3. Auswahl → App öffnet sich, ShareTargetPage erscheint.
-
-## Troubleshooting
-
-- **Error: No such module 'receive_sharing_intent'**
-  → Schritt 7 (Build Phases reorder) wurde übersprungen.
-- **Error: ‚Frameworks' not allowed in extension**
-  → In Build Settings der Share Extension `Other Linker Flags` und `Framework Search Paths` leeren (nur die geerbten Pod-Pfade behalten).
-- **Share-Sheet zeigt App nicht an**
-  → `NSExtensionActivationRule`-Limits in `Share Extension/Info.plist` zu klein? Werte testweise erhöhen. Außerdem: App muss **mindestens einmal nach Install** geöffnet worden sein, sonst wird die Extension von iOS nicht registriert.
-- **Files kommen mit `nil` Pfad an**
-  → App-Group nicht konsistent. Prüfen, dass `CUSTOM_GROUP_ID` in beiden Targets identisch ist und die Entitlement-Files dieselbe Group enthalten.
-
-## Was am Mac noch zu tun ist
-
-- Schritte 1–8 oben (~15 Min).
-- Auf physischem iPhone testen — Simulator-Share-Sheet ist eingeschränkt.

-# iOS Widget Extension — Xcode Setup
-
-Die Swift-Quellen unter `ios/TimetableWidgetExtension/` müssen einmalig in Xcode als **Widget Extension Target** verdrahtet werden — ohne diesen Schritt bleibt der Code unkompiliert.
-
-## Schritt 1 — Widget-Extension-Target anlegen
-
-1. `ios/Runner.xcworkspace` in Xcode öffnen.
-2. Projekt-Sidebar → `Runner` (Projekt-Root) → **+ Add Target** unten links.
-3. **iOS → Widget Extension** wählen.
-4. Eigenschaften:
-   - Product Name: `TimetableWidgetExtension`
-   - Bundle Identifier: `eu.mhsl.marianum.mobile.client.TimetableWidgetExtension`
-   - Language: Swift
-   - Include Configuration Intent: **OFF** (StaticConfiguration reicht)
-   - Embed in: Runner
-5. Beim Activate-Scheme-Dialog auf **Cancel** klicken.
-
-## Schritt 2 — Vorhandene Quelldateien ins Target ziehen
-
-Xcode hat zunächst Dummy-Dateien (`TimetableWidgetExtension.swift`, `TimetableWidgetExtensionBundle.swift`) angelegt. Diese **löschen** (Move to Trash). Dann:
-
-1. Sidebar → Rechtsklick auf den Ordner `TimetableWidgetExtension` → **Add Files to "Runner"…**
-2. Im File-Picker zu `ios/TimetableWidgetExtension/` navigieren und alle `.swift`-Dateien, die `Info.plist`, `TimetableWidgetExtension.entitlements` **und den `Assets.xcassets`-Ordner** selektieren (mit `marianum_m`-Asset darin — gleicher Asset-Name wie auf Android-Seite).
-3. **Wichtig**: bei „Add to targets" nur `TimetableWidgetExtension` ankreuzen, **nicht** Runner.
-
-## Schritt 3 — App Group aktivieren
-
-Beide Targets brauchen die App-Group-Berechtigung, damit Hauptapp und Widget über `UserDefaults(suiteName:)` schreiben/lesen können.
-
-1. **Runner**-Target → **Signing & Capabilities** → **+ Capability** → **App Groups**.
-   - Group-ID hinzufügen: `group.eu.mhsl.marianum.mobile.client.widget`
-2. Dasselbe für **TimetableWidgetExtension** — mit derselben Group-ID.
-
-Im Apple-Developer-Portal muss die App-Group bei beiden App-IDs eingetragen sein, sonst schlägt das Provisioning fehl.
-
-## Schritt 4 — Entitlements verlinken
-
-1. **Runner** → Build Settings → `CODE_SIGN_ENTITLEMENTS` sollte bereits auf `Runner/Runner.entitlements` zeigen.
-2. **TimetableWidgetExtension** → Build Settings → `CODE_SIGN_ENTITLEMENTS` → auf `TimetableWidgetExtension/TimetableWidgetExtension.entitlements` setzen.
-
-## Schritt 5 — Info.plist + Deployment Target
-
-1. **TimetableWidgetExtension** → Build Settings → `INFOPLIST_FILE` → auf `TimetableWidgetExtension/Info.plist` setzen.
-2. Build Settings → `IPHONEOS_DEPLOYMENT_TARGET` ≥ 16.0 (Code gated `.containerBackground` mit `if #available(iOS 17, *)`, läuft also auch auf 16).
-
-## Schritt 6 — Build & Run
-
-- Scheme `Runner` (nicht das Widget-Scheme) wählen → Run.
-- Auf Home-Screen langes Drücken → Widget hinzufügen → "Marianum · Heute" / "Marianum · Woche".
-- Widget-Tap öffnet die App im zuletzt sichtbaren Tab. Eine Tab-Navigation auf den Stundenplan ist bewusst nicht implementiert (Android nutzt Intent-Extras, iOS würde dafür ein URL-Scheme oder AppIntent brauchen — beides bewusst ausgespart).
-
-## Troubleshooting
-
-- **Widget zeigt „Lade…"** auch nach Refresh: App-Group greift nicht. Prüfen, ob beide Targets dieselbe Group-ID haben und das Provisioning aktualisiert wurde.
-- **Stale-Daten nach Logout**: `WidgetSync.clear()` schreibt `widget_data_logged_in_v1 = false`; Widget zeigt dann den Login-Placeholder.
-- **Lessons um 1–2 Stunden verschoben**: Date-Parser-Bug. Sollte gefixt sein in `WidgetData.swift::parseDartDate` — verifizieren, dass die ISO-8601-Strings ohne Z-Suffix als `TimeZone.current` geparsed werden.
-- **App-Store-Submit später**: `Runner.entitlements` `aps-environment` von `development` auf `production` umbiegen.
-
-## Was bereits im Repo erledigt ist
-
-- Alle Swift-Quellen, Info.plist, Entitlements liegen unter `ios/TimetableWidgetExtension/`.
-- App-Group-ID konsistent zwischen Dart (`WidgetSync.iosAppGroupId`), Swift (`WidgetDataKey.appGroupId`) und der Entitlements-Datei.
-- `home_widget`-Plugin auf der Dart-Seite konfiguriert; ruft `HomeWidget.setAppGroupId` beim ersten Sync.
-- `containerBackground` für iOS 17+ gegated, fällt auf iOS 16 sauber zurück.
-- Date-Parser fixt das fehlende Z-Suffix (Dart schreibt lokale Zeit ohne TZ-Marker).
-
-## Was am Mac noch zu tun ist
-
-- Schritte 1–5 oben in Xcode durchklicken (10–15 Min).
-- `flutter pub get` + `cd ios && pod install`.
-- Auf physischem Gerät oder iOS-Simulator (≥ 16.0) bauen.
-- Widget aufs Home-Screen ziehen, prüfen dass Lesson-Zeiten korrekt rendern.
