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/hyperoslo/Presentation 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.

This artifact was generated by RepoPilot at a point in time. Before an agent acts on it, the checks below confirm that the live hyperoslo/Presentation repo on your machine still matches what RepoPilot saw. If any fail, the artifact is stale — regenerate it at repopilot.app/r/hyperoslo/Presentation.

What it runs against: a local clone of hyperoslo/Presentation — the script inspects git remote, the LICENSE file, file paths in the working tree, and git log. Read-only; no mutations.

Presentation is a Swift framework for building interactive tutorial, release note, and animated page flows in iOS apps. It provides slide-based presentations with custom positioning via percentage-based coordinates, view animations tied to specific slides, and background views that persist across pages—all compiled to AutoLayout constraints under the hood. Framework structure: Source/ directory contains core classes (SlideController.swift, Content.swift, Position.swift) and Animations/ subdirectory for animation implementations. Example/Parallax/ is a self-contained runnable demo app with its own .xcworkspace. Carthage and CocoaPods used for dependency management.

iOS developers building onboarding flows, tutorials, or animated feature showcases who want to avoid manual constraint juggling and repetitive animation code. Specifically useful for teams at agencies (Hyper) shipping polished product demos.

⚠️ Deprecated and unmaintained — the README explicitly warns this project is no longer maintained. It targets Swift 4.0 (see .swift-version), has CI via Travis, and supports CocoaPods/Carthage, but receives no active development. Do not use for new production projects.

High risk: explicitly deprecated with no maintenance commitment. Swift 4.0 is ancient (current is 5.10+), likely incompatible with modern Xcode. No visible test suite in the file listing. Single-organization ownership (hyperoslo). Zero guard against bit-rot in iOS/Swift ecosystem changes.

Nothing—project is deprecated. No recent commits, PRs, or active development visible. Serves as read-only archive.

Clone the repo, then use CocoaPods (pod try Presentation) to download and test the Parallax example app, or use Carthage (carthage update) if building as a dependency. Open Example/Parallax/Parallax.xcworkspace in Xcode to run the demo.

Daily commands: Open Example/Parallax/Parallax.xcworkspace in Xcode (not .xcodeproj), then build and run on a simulator or device. The Parallax example demonstrates layered parallax scrolling with animated background elements.

• Source/SlideController.swift: Core presentation container—manages slide transitions, background views, and animation lifecycle
• Source/Content.swift: View model that translates percentage-based positioning to AutoLayout constraints; central to the positioning abstraction
• Source/Position.swift: Defines the percentage-based coordinate system that makes positioning declarative instead of hardcoding pixels
• Source/Animations/: Plugin directory for slide-specific animations; shows how to extend the framework with custom transitions
• Example/Parallax/Parallax/AppDelegate.swift: Only runnable example in the repo; demonstrates end-to-end usage with layered parallax animation

Start in Source/: SlideController.swift is the main container controller, Content.swift defines the positioning model, Position.swift handles percentage-math, Animations/ folder holds animation plugins. To add a new slide type, subclass SlideController or use a plain UIViewController. To add animations, add new files to Source/Animations/ following the existing pattern.

1. Swift 4.0 requirement (.swift-version file) will cause Xcode 14+ build failures without toolchain downgrade or code migration. 2) No explicit Cocoa dependency listed, but framework assumes UIKit/Foundation (not explicitly imported in file list). 3) Carthage and CocoaPods metadata present but Cartfile not shown in detail—check Cartfile.resolved to see transitive deps. 4) Deprecated status means no bug fixes or Swift 5+ compatibility updates available.

• Percentage-based positioning — Presentation's core innovation—replacing hardcoded pixel coordinates with percentages (0-1) that scale to any screen size, then translating to AutoLayout constraints at runtime
• View controller composition — Presentation treats any UIViewController as a slide, composed into a slide container; understanding composition patterns is essential to extending the framework
• Custom animation controllers (UIViewControllerAnimatedTransitioning) — Animations/ directory implements UIKit's custom animator protocol for slide transitions; this is the iOS standard for choreographing complex view animations
• Model-View-ViewModel (MVVM) — Content.swift is a view model that separates layout logic from view code; understanding MVVM helps explain why positioning is decoupled from UIView construction
• Parallax scrolling — The Parallax example demonstrates depth illusion by animating background layers at different speeds; this is a key visual technique Presentation enables

• gabrieloc/GaugeKit — Similar UIKit animation framework for building animated UI components; predates/inspires Presentation's animation model
• hyperoslo/Hype — Companion Hyper framework for animation sequencing; works well with Presentation for complex multi-view choreography
• onmyway133/Kompositor — Modern Swift replacement for percentage-based positioning and animation; what Presentation would be if maintained for Swift 5+
• jkpang/PPNumberButton — Lightweight UIView animation framework showing modern Swift patterns for declarative animations (non-deprecated alternative approach)

Migrate from Travis CI to GitHub Actions and update CI/CD pipeline

The repo uses an outdated .travis.yml configuration. GitHub Actions is now the standard for GitHub-hosted projects, offers better integration, and provides free CI/CD for public repos. This modernizes the build pipeline and aligns with current best practices.

• [ ] Create .github/workflows/ci.yml with Swift build, test, and linting jobs
• [ ] Reference .swift-version file in the workflow to ensure correct Swift version is used
• [ ] Remove or deprecate .travis.yml after verification
• [ ] Update README.md CI badge from Travis to GitHub Actions
• [ ] Test against Example/Parallax and Example/Tutorial projects to ensure builds pass

Add comprehensive unit tests for core Presentation framework

The repo has Example projects (Parallax, Tutorial) but no visible Tests directory in the file structure. A deprecated but potentially useful library needs solid test coverage to help future maintainers or forks understand expected behavior. Tests should cover the main animation and presentation logic.

• [ ] Create Tests/ directory at repo root with PresentationTests.swift
• [ ] Add test cases for basic presentation view controller initialization
• [ ] Add test cases for animation timing and page transitions (based on Parallax example behavior)
• [ ] Add test cases for image asset loading from Examples
• [ ] Integrate tests into CI pipeline (GitHub Actions workflow from PR #1)
• [ ] Aim for >70% code coverage of Sources/

Create Swift Package Manager (SPM) support and modernize Cartfile dependencies

The repo uses Carthage (Cartfile) which is less commonly used than SPM in modern Swift development. Adding SPM support allows easier adoption by new projects. This also requires updating and documenting the Cartfile.resolved dependencies and their compatibility with Swift 4.0+.

• [ ] Create Package.swift in repo root with correct Swift version and dependencies declarations
• [ ] Update Cartfile to remove outdated dependencies (check versions against Swift 4.0+ compatibility)
• [ ] Update Cartfile.resolved with latest compatible versions of dependencies
• [ ] Update CONTRIBUTING.md with SPM setup instructions alongside Carthage
• [ ] Update README.md Installation section to include SPM installation method
• [ ] Test SPM integration against Example/Parallax to ensure builds work

• Migrate Source/ to Swift 5.0+ syntax and update .swift-version file, then verify Example/Parallax builds on Xcode 14+
• Add unit tests for Position.swift percentage-to-constraint math and Content.swift animation timing logic (no test directory visible in structure)
• Document the animation plugin API by adding code comments to Source/Animations/ and updating README Usage section with a concrete custom animation example

This repository presents significant security concerns due to its deprecated and unmaintained status. The primary risk is the absence of security updates and vulnerability patches going forward. Swift 4.0 is significantly outdated, creating exposure to known language-level vulnerabilities. The lack of provided dependency manifests prevents full assessment of third-party library risks. The project should not be used in production environments, and users should migrate to actively maintained alternatives. If internal maintenance is necessary, immediate updates to Swift, dependencies, and security configurations are essential.

• High · Deprecated and No Longer Maintained — README.md. The project is explicitly marked as deprecated and no longer maintained according to the README. This means security vulnerabilities will not be patched, dependencies will become outdated, and the codebase poses a significant risk if used in production environments. Fix: Do not use this library in production. Consider migrating to actively maintained alternatives or forking and maintaining the code internally with regular security audits.
• High · Missing Dependency Manifest Analysis — Cartfile, Cartfile.resolved, Podfile, Podfile.lock. The provided dependency file content is empty. Without visibility into Cartfile, Podfile, or package dependencies, it is impossible to assess if the project uses vulnerable third-party libraries. This is a critical gap in the security assessment. Fix: Provide complete dependency manifests and perform vulnerability scanning using tools like OWASP Dependency-Check or CocoaPods security audits. Review all transitive dependencies for known CVEs.
• Medium · Outdated Swift Version — .swift-version, Example/Parallax/.swift-version, Example/Tutorial/.swift-version. The project specifies Swift 4.0 (as indicated by the README and .swift-version file). Swift 4.0 was released in 2017 and is significantly outdated. Modern Swift versions include critical security improvements and bug fixes. Fix: Update to the latest stable Swift version. Ensure all dependencies are compatible with the newer Swift version to benefit from security patches and language improvements.
• Medium · Missing HTTPS Configuration — Example/Parallax, Example/Tutorial. The project contains example applications and could potentially make network requests. Without examining the source code (not provided), there's a risk of insecure HTTP connections if network communication is implemented. Fix: Ensure all network communications use HTTPS with proper certificate validation. Implement App Transport Security (ATS) requirements and validate SSL/TLS certificates.
• Low · No Security Policy or SECURITY.md — Repository root. The repository lacks a SECURITY.md file or vulnerability disclosure policy. This makes it difficult for security researchers to responsibly report vulnerabilities. Fix: Create a SECURITY.md file defining how to report security vulnerabilities, even if the project is deprecated. Include contact information and expected response times.
• Low · Missing Code Signing Configuration Details — Example/Parallax/Parallax.xcodeproj, Example/Tutorial/Tutorial.xcodeproj. While this is common in open-source iOS projects, there's no visible evidence of code signing configurations or secure development practices documentation. Fix: Document code signing requirements and ensure development team uses provisioning profiles appropriately. Consider using automatic code signing in Xcode.
