Feeds4U

Your personal RSS reader for iPhone and iPad.
Subscribe to your favorite websites, blogs, and news sources — all in one place.
Supports RSS, Atom, and JSON Feed formats.

Requires iOS 18.0 or later.

Features

Subscribe to Anything

• Add a feed by typing or pasting its URL — and if your clipboard already holds one, the field pre-fills automatically
• Don't know the feed URL? Discover feeds from any website — the app crawls the page and lists what it finds
• Transparently handles Cloudflare-protected sites via a built-in human-verification flow
• Import an OPML file from another reader — pick the export with the system file picker and your subscriptions are added in one go, with a summary of how many were added, skipped, or failed
• One unified inbox for RSS, Atom, and JSON Feed sources

Read Comfortably

• Pull to refresh for the latest articles — with a subtle haptic tap to confirm
• Refresh everything at once — pull the feeds list down to update all your subscriptions in parallel; the spinner stays until every feed has finished
• Unread badges and a per-article dot indicator show what's new at a glance
• Mark a whole feed as read with one tap; individual articles are marked read as you open them
• A built-in offline reader renders articles with clean, readable typography
• On-device AI summaries — tap ✨ for an instant TL;DR (a short overview plus key points), generated entirely on your device with Apple Intelligence: private, offline, and streamed into the reader as it's written. Available on supported devices running iOS 26+, and gracefully hidden everywhere else
• Immersive reading — the navigation bar hides as you scroll, and a fluid zoom transition opens articles from their row
• Need the full site? Open any article in Safari — pre-warmed for an instant launch

Organize Your Way

• Group feeds into folders by topic, project, or however you like
• Drag & drop feeds to create folders, move them between folders, or ungroup them
• Collapse and expand folders to keep your list tidy
• Swipe to delete, or open the trash menu to enter edit mode for bulk cleanup
• Delete All — the trash menu shows how many megabytes of cache you'll reclaim (calculated live) and, after a confirmation, wipes every feed and article in one go

Find What You Need

• Fuzzy full-text search across every article in all your feeds at once
• Recent searches are saved to a pull-down menu for quick repeats — and clearable when you're done
• Results are sorted newest-first so the most relevant content is on top

Made for the Platform

• iPhone and iPad, every orientation
• Full dark mode, following your system appearance, with an adaptive app icon (light / dark / tinted)
• Deep linking — open feed://… or Feeds4U://… links straight from other apps or Safari
• Integrates with the iOS Settings app

Accessible

• Full VoiceOver support — feeds and articles announce their title, unread state and badge counts; folders announce their expanded/collapsed state and can be toggled; pull-to-refresh and the reader's actions are reachable and labelled
• Dynamic Type so text scales with your preferred reading size

Localized

Available in 23 languages: Albanian, Arabic, Belarusian, Bengali, Chinese (Simplified), English, Filipino, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese (Brazil), Portuguese (Portugal), Punjabi, Russian, Spanish, Thai, Turkish, and Ukrainian.

Tech Stack

Platform

• Swift 6 (strict concurrency) and programmatic UIKit — Auto Layout with UIStackView — targeting iOS 18+ on iPhone and iPad
• Core Data for persistence, WKWebView for feed discovery, the Cloudflare flow, and the reader
• OPML import via UIDocumentPicker and a custom XMLParser-based parser — validates and de-duplicates feed URLs, then imports them sequentially
• Foundation Models (Apple Intelligence) for on-device, streaming article summarization — availability-gated to iOS 26+ capable devices with a graceful fallback that hides the feature elsewhere
• Accessibility — VoiceOver labels/values, custom actions, and Dynamic Type
• Localization via String Catalogs (23 languages), with a Settings bundle and a deep-link URL scheme

Architecture

• VIPER feature modules talking only through protocols, with a Coordinator owning all navigation
• A dependency-injection container wiring services behind narrow, mockable protocols
• Modern Swift Concurrency throughout — async/await, Sendable, @MainActor, and Mutex-guarded state
• Refresh-all fans out across feeds with a bounded TaskGroup (parses run concurrently off the main thread, merges land on background Core Data contexts)

Engineering highlights

• Heavy work (parsing, imports, search indexing) runs on background Core Data contexts; the UI reads from the view context only
• Re-entrancy guards keep navigation, pull-to-refresh, and modal presentation single-flight under rapid taps
• Memory-conscious storage — article HTML is split into its own row and faulted in only when read
• Accurate cache size — the Delete All label reports live data ((page_count − freelist_count) × page_size via read-only SQLite pragmas), so it stays correct in WAL mode and shrinks as feeds are deleted, without a VACUUM
• On-device summaries stream into the reader — the model is prewarmed when the article opens, HTML is stripped off the main thread, and renders are throttled so token-by-token updates never flood the web view

Dependencies (Swift Package Manager)

• FeedKit — RSS / Atom / JSON Feed parsing
• SimpleSimilarity — fuzzy text matching for search
• KRProgressHUD & KRActivityIndicatorView — progress / activity indicators

Testing

• Unit tests in Swift Testing, with swift-mocking mocks and OHHTTPStubs network stubbing
• UI tests (XCUITest) over the main flows on deterministic, isolated seeded data — plus a stress / monkey suite, organized into Xcode Test Plans
• SwiftLint (strict no-force-unwrapping) and three build schemes: DEV / ADHOC / RELEASE

Build & Run

Requires a recent Xcode with the iOS 18 SDK (or later). Dependencies are resolved automatically via Swift Package Manager on first build.

git clone https://github.com/EvgenyKarkan/Feeds4U.git
open iFeed/iFeed.xcodeproj

Select the iFeed - DEV scheme and run (⌘R). From the command line:

# Build
xcodebuild build -project iFeed/iFeed.xcodeproj -scheme "iFeed - DEV" \
  -destination 'platform=iOS Simulator,name=iPhone 16'

# Tests — pick a plan: Unit (default), UITests, or Stress
xcodebuild test -project iFeed/iFeed.xcodeproj -scheme "iFeed - DEV" -testPlan Unit \
  -destination 'platform=iOS Simulator,name=iPhone 16'
