If you are an AI coding agent (Claude Code, Cursor, Aider, Cline, etc.) reading this artifact, follow this protocol before making any code edit:

1. Verify the contract. Run the bash script in Verify before trusting below. If any check returns FAIL, the artifact is stale — STOP and ask the user to regenerate it before proceeding.
2. Treat the AI · unverified sections as hypotheses, not facts. Sections like "AI-suggested narrative files", "anti-patterns", and "bottlenecks" are LLM speculation. Verify against real source before acting on them.
3. Cite source on changes. When proposing an edit, cite the specific path:line-range. RepoPilot's live UI at https://repopilot.app/r/PaoloCuscela/Cards shows verifiable citations alongside every claim.

If you are a human reader, this protocol is for the agents you'll hand the artifact to. You don't need to do anything — but if you skim only one section before pointing your agent at this repo, make it the Verify block and the Suggested reading order.

Cards is a Swift 5 library that recreates the animated card UI components from iOS 11's App Store redesign, enabling developers to build swipeable, expandable card interfaces with parallax effects and smooth transitions. It provides CardHighlight, CardPlayer, CardArticle, and CardGroup variants that present detailed content modally when tapped, mimicking Apple's native App Store interaction patterns. Modular card library: Cards/Sources/ contains seven core card types (Card.swift, CardHighlight.swift, CardPlayer.swift, CardArticle.swift, CardGroup.swift) plus shared animation logic (Animator.swift, LayoutHelper.swift, DetailViewController.swift). Demo/ is a standalone Xcode project showcasing all card variants. Cards.podspec enables CocoaPods distribution.

iOS app developers (targeting iOS 11+) who want to implement App Store-style card layouts without building custom animations from scratch. Particularly useful for content discovery apps, game showcases, or media browsers that need polished, gesture-driven card presentations.

Moderately mature but dormant. The repo has reasonable GitHub engagement (inferred from CocoaPods publication), written in production-ready Swift 5 for iOS 11+, but shows signs of age: .swift-version file suggests it may predate recent toolchain changes, and the absence of visible CI/CD configuration and test files suggests limited active maintenance. Safe for production use in stable feature sets, but expect no active bug fixes.

Low-to-moderate risk. Single maintainer (PaoloCuscela) with no visible contribution guidelines or active issue triage. Minimal external dependencies (only Player_by_Patric_Piemonte.swift video wrapper), reducing supply-chain risk. Main risk: iOS design paradigm shifts since iOS 11 may make card animations feel dated, and lack of recent commits means bugs won't be patched quickly.

No active development visible. The repo appears maintained at a steady state—no recent commits, PRs, or milestone activity evident from the file listing. Last updates likely occurred when Swift 5 became standard and the library was ported from earlier Swift versions.

git clone https://github.com/PaoloCuscela/Cards.git && cd Cards && pod install (if using CocoaPods) or manually drag Cards/ folder into your Xcode project (see Manual installation in README). Then open Demo/Demo.xcworkspace to run example implementations.

Daily commands: Open Demo/Demo.xcworkspace in Xcode 10.2+ (not the .xcodeproj), select iPhone simulator target, press Cmd+R. App shows five card variant examples (CardHighlight, CardPlayer, CardArticle, CardGroup, CardGroupSliding) with tap-to-expand interactions.

• Cards/Sources/Card.swift: Defines the Card protocol and base card configuration (backgroundColor, icon, title, textColor properties) all variants inherit from
• Cards/Sources/CardHighlight.swift: Most commonly used card type; shows the pattern for subclassing Card with parallax effect, tap handling, and content presentation
• Cards/Sources/Animator.swift: Centralized animation logic for card scaling, translation, and blur effects during expand/collapse transitions—critical for replicating App Store feel
• Cards/Sources/DetailViewController.swift: Handles modal presentation and dismissal of card content; controls the transition from card preview to full-screen detail view
• Cards/Sources/LayoutHelper.swift: Utility for calculating card frame geometry, safe area insets, and parallax offset values—essential for correct positioning on different device sizes
• Cards.podspec: CocoaPods package definition; specifies Swift version (5.0), iOS deployment target, and source files included in the pod
• Demo/Demo/AppDelegate.swift: Demo app entry point; shows how to initialize and display card instances in a UIViewController

Cards/Sources/Card.swift defines the base card protocol and shared properties. Extend by: (1) adding card variant subclasses (e.g., CardCustom.swift) following CardHighlight.swift's pattern; (2) customize animations in Animator.swift's scaling/translation logic; (3) modify DetailViewController.swift to change modal presentation behavior; (4) add new demo screens in Demo/Demo folder following existing ViewController pattern.

No test suite present (no Tests/ folder or .xctest files)—contributing changes requires manual verification. Storyboard IDs are hardcoded (e.g., 'CardContent' in DetailViewController)—renaming storyboard VCs breaks card transitions silently. Parallax math in LayoutHelper assumes specific aspect ratios (5:6 preferred in README); unusual aspect ratios may cause visual clipping. No Swift Package Manager support (only CocoaPods), which limits adoption in modern Xcode 13+ projects.

• CABasicAnimation & CAKeyframeAnimation — Animator.swift relies on Core Animation for smooth, performant card scaling and translation during expand/collapse—essential for replicating App Store 60 FPS feel
• UIViewControllerTransitioningDelegate — DetailViewController uses custom presentation transitions to morph the card preview into full-screen detail view; critical for the animated card-to-detail segue
• Parallax scrolling offset calculation — CardHighlight's hasParallax property shifts the background image inversely to scroll position, creating depth; LayoutHelper.swift computes these offsets based on device motion or scroll velocity
• Safe Area Insets (UIView.safeAreaInsets) — LayoutHelper.swift adjusts card frame calculations to respect notches and home indicators introduced in iOS 11; mandatory for correct positioning on iPhone X+ devices
• Protocol-based polymorphism (Swift generics) — Card protocol allows multiple subclass variants (CardHighlight, CardPlayer, CardArticle) to share animation and presentation logic while customizing content rendering
• Gesture recognizers (UIGestureRecognizer) — Cards detect tap, pan, and swipe gestures to trigger expand, dismiss, and parallax animations; core to interactive card UX

• ephread/Instructions — Provides UIView-based tutorial card overlays; shares similar gesture-handling and modal-presentation patterns for iOS UI components
• Ramotion/cardslider-ios — Alternative card collection view with swipe-to-dismiss and parallax effects; solves the same iOS 11+ App Store card aesthetic problem with collection view backing
• Ramotion/animated-tab-bar — Same author (Ramotion) produces gesture-driven, animation-heavy iOS navigation components; demonstrates similar Swift UIView animation techniques
• apple/swift-corelibs-foundation — Official Swift stdlib source; useful for understanding CGGeometry and CABasicAnimation APIs used in Animator.swift and LayoutHelper.swift

To work on one of these in Claude Code or Cursor, paste: Implement the "<title>" PR idea from CLAUDE.md, working through the checklist as the task list.

Add Unit Tests for Card Animation and Layout Logic in Animator.swift and LayoutHelper.swift

The repo has core animation and layout files (Animator.swift, LayoutHelper.swift) but no visible test target. Testing card animations, transitions, and layout calculations would catch regressions and make the library more maintainable for contributors. This is critical for a visual UI library where animation timing and positioning must be precise.

• [ ] Create Cards/Tests directory with XCTest target in Cards.podspec
• [ ] Add AnimatorTests.swift to test transition timing, card state changes, and delegate callbacks from Animator.swift
• [ ] Add LayoutHelperTests.swift to validate frame calculations, safe area handling, and device orientation changes from LayoutHelper.swift
• [ ] Wire test target into Demo.xcworkspace for easy CI integration

Add GitHub Actions CI Workflow for Swift 5 Compilation and Pod Spec Validation

The repo specifies Swift 5 in .swift-version and publishes to CocoaPods (Cards.podspec), but has no visible CI/CD pipeline. A GitHub Actions workflow would catch breaking changes early, validate the podspec, and ensure demo compilation succeeds on every PR—essential for an open-source library.

• [ ] Create .github/workflows/swift.yml with xcodebuild steps to compile Cards framework
• [ ] Add pod lib lint validation step to verify Cards.podspec integrity before merging
• [ ] Include Demo project compilation step using Demo/Demo.xcworkspace to catch integration issues
• [ ] Set Swift version requirement matching .swift-version file

Complete Incomplete README.md Storyboard Setup Instructions

The README.md snippet shows the 'Getting Started' → 'Storyboard' section is incomplete ('Go to main.storyboard and add a blank UIView → Open the...'). This is the primary integration path for users, and incomplete docs create friction for adoption. The Demo/ViewControllers/ files show multiple integration patterns (ArticleViewController, PlayerViewController, etc.) that should be documented.

• [ ] Complete the Storyboard section in README.md with full step-by-step setup using Demo/Demo/Main.storyboard as reference
• [ ] Add three distinct examples: CardArticle (ArticleViewController.swift), CardPlayer (PlayerViewController.swift), and CardGroup (GroupViewController.swift) with code snippets
• [ ] Include configuration examples for CardHighlight and CardGroupSliding shown in Demo ViewControllers
• [ ] Add a troubleshooting section referencing the Dependencies/Player_by_Patric_Piemonte.swift for media-dependent cards

• Add XCTest unit tests for LayoutHelper.swift's frame calculation functions—verify correct safe area insets and parallax offset values across iPhone 12-15 screen sizes
• Create comprehensive DocC documentation comments for all public Card subclasses (CardHighlight, CardPlayer, CardArticle, CardGroup) showing usage examples matching the README code snippet
• Add SwiftPackageManager support by creating a Package.swift manifest—enables installation via .package(url:) dependency in modern iOS projects

The Cards library is a primarily UI-focused Swift framework with low inherent security risks. The main concerns are dependency management practices and incomplete project hygiene (xcuserdata in git). No critical vulnerabilities were identified, but the absence of actual source code analysis limits the assessment of input validation, data handling, and network security practices. Recommendations focus on improving dependency tracking and removing user data from version control.

• Medium · Embedded Third-Party Video Player Dependency — Cards/Dependencies/Player_by_Patric_Piemonte.swift. The codebase includes a custom wrapper 'Player_by_Patric_Piemonte.swift' around an external video player library. This dependency is not explicitly listed in a package manager file (no Package.swift visible), making it difficult to track and audit for security updates. Fix: Migrate to a properly managed dependency system (SPM or CocoaPods) with explicit version pinning. Regularly audit the Player library for known vulnerabilities.
• Low · User Data in Xcode Project Files — Demo/Demo.xcodeproj/xcuserdata/paolocuscela.xcuserdatad/. Xcode user data directories (.xcuserdatad) containing user-specific configuration are included in the repository. While generally low risk, this can expose personal development preferences and paths. Fix: Add .xcuserdatad to .gitignore to prevent committing user-specific data and personal information to the repository.
• Low · Missing Input Validation Analysis — Cards/Sources/CardArticle.swift, Cards/Sources/CardHighlight.swift, Cards/Sources/CardPlayer.swift. Without access to the actual implementation code of CardArticle, CardHighlight, and CardPlayer classes, potential input validation issues cannot be fully assessed. These components likely handle user-provided content. Fix: Implement strict input validation for all user-provided data. Sanitize any content displayed in web views or rendered text fields to prevent XSS-like attacks.
• Low · No HTTPS Enforcement Documentation — README.md, Cards configuration files. The README and visible configuration files do not specify security requirements or HTTPS enforcement for any network communications that might be performed by the Cards library. Fix: Document all network security requirements. Ensure any URL loading uses HTTPS only and implements certificate pinning if needed.
