Wallpy iOS — My 2020 Android app, rebuilt for iPhone

This is the iOS clone of my own Wallpy Android app (originally released in 2020). Same catalogue and backend, but rewritten with SwiftUI and Swift Concurrency.

What it is

• A wallpaper browser fed by Firebase Realtime Database JSON.
• Imgur hosts the actual images; Firebase stores Imgur links.
• Grid is uniform 3-column, 9:16 tiles; detail view shows full quality; saving/sharing uses the original image.

Data & infrastructure

• Firebase RTDB: Holds plain JSON lists per category (All.json, Anime.json, etc.) plus a CurrentVersion node for update checks.
• Imgur hosting: Links in Firebase already include quality suffixes (e.g., ...m.jpg, ...l.jpg, ...h.jpg). The app strips suffixes to recover the base/original, then reapplies controlled suffixes when needed.
  • Grid thumbnails: uses a preferred thumbnail suffix (l by default).
  • Detail, save, share: always fetch the suffix-free original URL.
• Config: WallpyIOS/WallpyIOS/Config/FirebaseConfig.plist defines the Firebase database URL, categories, and suffix choices.
• Networking: Plain REST via URLSession + async/await (no Firebase SDK).
• Caching: Lightweight in-memory image cache so images stay visible after fast scrolling.

Notes

• iOS cannot set the system wallpaper programmatically; users save to Photos and apply manually.
• Share uses the actual image (not just the URL).
• If you add auth or change Firebase paths, update FirebaseConfig.plist accordingly.

Wallpy iOS is a faithful Apple-native clone of my own Wallpy Android app (2020) — same creator, same pipeline, new platform.
