iOS (neu, ios/):
- SwiftUI-App: Login (Server + Keychain-Token), Kamera-Scanner (EAN/UPC/Code128),
Einlagern mit mehreren Chargen und eigenem MHD, Auslagern mit Chargenauswahl
oder FEFO, Artikelsuche, Anlegen mit Open-Food-Facts-Vorbefuellung.
- Home-Screen-Shortcuts: Schnellaktionen (langer Druck) und URL-Schema
projectgood://checkin | ://checkout fuer eigene Symbole via Kurzbefehle.
- project.yml (XcodeGen) + README mit Build-Anleitung. NICHT kompiliert - auf
diesem Rechner ist kein Xcode vorhanden.
Import-Modi (wie besprochen sinnvoll):
- add (Standard, nichts loeschen), replace_listed (Bestaende der in der Datei
genannten Produkte ersetzen - fuer Inventur), replace_all (alles ersetzen).
Geleerte Bestaende werden als Korrektur-Bewegung protokolliert; die Oberflaeche
fragt bei den zerstoerenden Modi nach.
Anzeige:
- "Bald ablaufend"/"Abgelaufen" zeigen jetzt das Gebinde ("1 Glas") mit der
Basiseinheit klein darunter (ExpiringItem liefert die Einheiten mit).
- MHD als Zeitspanne mit korrektem Numerus: "in 3 Tagen", "in 1 Woche",
"vor 2 Wochen", dazu heute/morgen/gestern.
