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/raulriera/TextFieldEffects 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.

TextFieldEffects is a Swift library that provides 9 custom UITextField subclasses with polished animation and visual effects (Kaede, Hoshi, Jiro, Isao, Minoru, Yoko, Madoka, Akira, Yoshiko) inspired by the Codrops article on text input interactions. Each effect implements a distinct enter/focus animation, label positioning, and visual feedback pattern. It solves the problem of adding sophisticated text field interactions to iOS apps without building custom animations from scratch. Simple flat structure: TextFieldEffects/TextFieldEffects/ contains 9 individual effect files (AkiraTextField.swift, HoshiTextField.swift, etc.) as separate UITextField subclasses plus a shared TextFieldEffects.swift module file. TextFieldsDemo/ provides a demo app with ExampleTableViewController.swift showcasing all effects. Everything lives in a traditional Xcode project (TextFieldEffects.xcodeproj) with SPM support via Package.swift.

iOS developers building apps with Swift who want to replace vanilla UITextField with visually distinctive, animated input fields. Designers and developers using Interface Builder benefit from IBDesignable/IBInspectable support for real-time preview and customization in Xcode.

Moderately mature but aging. The project has 9 polished effects with comprehensive examples, Travis CI configured, and CocoaPods/Carthage/SPM distribution. However, the last significant activity appears dated (based on the archived tag mentions for Swift 1.2, 2.1, 2.3 support), and there's no evidence of recent commits or active maintenance in the file structure provided.

Single-maintainer risk is high (raulriera as sole author visible). The project has zero external dependencies (no Podfile shown), which is good for stability but bad for maintenance burden—all 9 effects are custom-built in-house. No test files visible in the top 60 important files suggests minimal test coverage. Swift version fragmentation history (tags for 1.2, 2.1, 2.3) indicates it may lag behind current Swift/iOS SDKs.

No active development signals are visible in the provided file list. The repo includes .travis.yml for CI but no recent commit metadata. The CHANGELOG.md and stale.yml bot configuration suggest the project is in maintenance mode rather than active development.

git clone https://github.com/raulriera/TextFieldEffects.git
cd TextFieldEffects
open TextFieldEffects/TextFieldEffects.xcodeproj
# For SPM: add github 'raulriera/TextFieldEffects' to your Package.swift

Alternatively, drag TextFieldEffects/TextFieldEffects/ folder directly into your Xcode project to avoid framework stripping issues.

Daily commands: Open TextFieldEffects/TextFieldEffects.xcodeproj in Xcode, select the TextFieldsDemo scheme, and press Cmd+R. Or use xcodebuild -scheme TextFieldsDemo from the command line. No external build steps, package managers, or servers required.

• TextFieldEffects/TextFieldEffects/TextFieldEffects.swift — Base protocol and shared functionality that all custom text field effects inherit from; defines the core animation and styling interface.
• TextFieldEffects/TextFieldEffects/HoshiTextField.swift — Reference implementation of a text field effect demonstrating the standard pattern for creating animated underline and label effects.
• TextFieldEffects/TextFieldEffects/AkiraTextField.swift — Complex effect implementation showing advanced animation composition and state management for floating labels.
• TextFieldEffects/TextFieldsDemo/ExampleTableViewController.swift — Demo app controller that shows integration patterns and how to instantiate and configure all available text field effects.
• Package.swift — Swift Package Manager manifest defining module structure, deployment target, and library configuration.
• TextFieldEffects.podspec — CocoaPods manifest specifying version, dependencies, and iOS deployment requirements for distribution.

• TextFieldEffects (Base Protocol) (Swift Protocol, UITextField) — Defines updateViewsForEditingEvents() interface that all effects must implement; acts as contract for animation behavior
  • Failure mode: If updateViewsForEditingEvents() is not overridden, effect will not animate on focus/blur; UITextField will function but appear unstyled
• Individual Effect Classes (Hoshi, Akira, etc.) (CABasicAnimation, CAShapeLayer, CAMediaTimingFunction) — Each subclass creates CAShapeLayer objects, defines animation keyframes, and implements the protocol to produce a unique visual effect
  • Failure mode: Animation freezes if CATransaction is not closed; if CADisplayLink is improperly managed, animations will stutter or disappear
• ExampleTableViewController (UITableViewController, UITableViewDataSource) — Instantiates all nine effects, displays them in table cells, and allows user interaction to trigger animations
  • Failure mode: If cells are not properly dequeued, memory will leak; if effect references are not retained, animations will cancel prematurely
• Core Animation Render Server (Metal/OpenGL (system-level GPU)) — System process that executes CABasicAnimation keyframes and composites updated layers to the screen buffer at 60/120 fps
  • Failure mode: If main thread blocks, animations become choppy; if keyframes have extreme durations, animations may be skipped entirely

Add a New Text Field Effect

1. Create new Swift file in TextFieldEffects/TextFieldEffects/ directory named after the effect (e.g., MyEffectTextField.swift) (TextFieldEffects/TextFieldEffects/HoshiTextField.swift)
2. Create a class that extends UITextField and conforms to the TextFieldEffects protocol, implementing required animation methods (TextFieldEffects/TextFieldEffects/TextFieldEffects.swift)
3. Implement updateViewsForEditingEvents() to handle focus/blur animations using CABasicAnimation or CADisplayLink (TextFieldEffects/TextFieldEffects/AkiraTextField.swift)
4. Add visual elements (CAShapeLayer for borders, UILabel for animated text) in init(frame:) or layoutSubviews() (TextFieldEffects/TextFieldEffects/JiroTextField.swift)
5. Register the new effect in ExampleTableViewController by adding an instance to the demo table view (TextFieldEffects/TextFieldsDemo/ExampleTableViewController.swift)

Customize an Existing Effect

1. Open the target effect file (e.g., HoshiTextField.swift) and modify color properties at the top of the class (TextFieldEffects/TextFieldEffects/HoshiTextField.swift)
2. Adjust animation timing and easing in updateViewsForEditingEvents() using CAMediaTimingFunction (TextFieldEffects/TextFieldEffects/HoshiTextField.swift)
3. Modify layer properties (lineWidth, cornerRadius, strokeColor) in layoutSubviews() for visual changes (TextFieldEffects/TextFieldEffects/HoshiTextField.swift)

Test an Effect in the Demo App

1. Build and run TextFieldsDemo target with Xcode scheme TextFieldEffects (TextFieldEffects/TextFieldEffects.xcodeproj/xcshareddata/xcschemes/TextFieldEffects.xcscheme)
2. The ExampleTableViewController automatically displays all registered effects; scroll to view each one (TextFieldEffects/TextFieldsDemo/ExampleTableViewController.swift)
3. Tap each cell to interact with the text field and observe the effect animations (TextFieldEffects/TextFieldsDemo/Base.lproj/Main.storyboard)

• UITextField subclassing — Allows direct control over text input behavior while layering custom animations without reimplementing text editing logic
• Core Animation (CABasicAnimation, CAShapeLayer) — Provides hardware-accelerated, smooth animations at 60fps without blocking main thread; essential for fluid visual effects
• Swift with protocol-oriented design — Enables code reuse across nine distinct effects through a common interface while keeping implementations lightweight
• CocoaPods + SPM dual distribution — Maximizes compatibility across iOS projects using either dependency manager; reduces friction for adoption

• Each effect is a separate UITextField subclass rather than a single configurable component

  • Why: Allows maximum visual and behavioral customization per effect without conditional logic; simplifies understanding of each design pattern
  • Consequence: Code duplication across files; updating common functionality requires changes to nine files; larger framework size

• Uses UIView animations triggered on editing events rather than persistent state machines

  • Why: Simpler event-driven API; integrates seamlessly with UITextField's built-in focus/blur callbacks
  • Consequence: Animation state is implicit; complex multi-stage effects (like Akira) require careful layer orchestration; harder to pause/resume animations

• No accessibility considerations (VoiceOver labels, dynamic type support)

  • Why: Focused on visual showmanship inspired by web design patterns; accessibility deemed secondary for demo/portfolio use
  • Consequence: Not suitable for production apps requiring WCAG compliance; text scaling unavailable for visually impaired users

• Does not provide form validation or input masking
• Does not handle secure password input state persistence or Keychain integration
• Does not support custom keyboard types or real-time text transformation
• Not a real-time collaborative editing framework
• Does not integrate with Core Data or any database layer

IBDesignable stripping: The README explicitly warns that using this as a framework can strip IBInspectable/IBDesignable in iOS (radar #21258097), so manual folder drag-and-drop is preferred over CocoaPods for Interface Builder support. Swift version lock: The project has tags for Swift 1.2, 2.1, 2.3 but the .swift-version file pins a specific version; mixing incompatible Swift versions in your project will cause compilation failures. No thread safety: These are UIView subclasses with no synchronization; all customization must happen on the main thread. Placeholder animation timing: Each effect hard-codes animation durations and timing curves in their implementation; changing one requires editing the Swift file directly (no global config).

• CABasicAnimation (Core Animation) — Each text field effect uses CABasicAnimation to animate placeholder label position, opacity, and scale on focus; understanding keyframes, duration, and timing functions is essential to modifying or creating new effects.
• IBDesignable & IBInspectable (Interface Builder) — All 9 effects use @IBDesignable and @IBInspectable decorators to render live previews in Xcode and expose customizable properties in the Interface Builder inspector; understanding this is crucial for framework adoption and end-user customization.
• UITextFieldDelegate protocol — Each effect overrides delegate methods like textFieldDidBeginEditing(), textFieldDidEndEditing(), and shouldChangeCharactersInRange() to trigger placeholder animations and respond to user input; mastery of this protocol is required to understand or extend effects.
• CAShapeLayer for custom drawing — Some effects use CAShapeLayer to draw underlines, borders, or custom shapes that animate in response to focus state; understanding path creation and stroke animation is needed to implement new visual effects.
• layoutSubviews() and view hierarchy management — Each effect overrides layoutSubviews() to position the placeholder label, underline, and borders correctly as the text field is resized or reoriented; this is critical for responsive, constraint-compatible effects.
• Material Design animation principles — The Codrops effects and their Swift implementations follow Material Design motion curves (cubic-bezier easing) for natural, polished animations; understanding these principles helps you appreciate and extend the subtle timing in each effect.

• codrops/TextInputEffects — Original CSS/JavaScript inspiration source; the Codrops article referenced in the README showing the web-based text input effects that this Swift library reimplements.
• SwiftyAttributes/SwiftyAttributes — Complementary Swift library for UITextField styling; often used alongside custom text fields to apply attributed string formatting.
• JVFloatLabeledTextField/JVFloatLabeledTextField — Alternative Objective-C/Swift library providing floating label animations for UITextField; solves a similar UX pattern to several TextFieldEffects (Hoshi, Yoshiko).
• ephread/Instructions — Companion library for iOS UI polish; often paired with custom text fields to create cohesive, polished user onboarding and input flows.
• FormValidatorSwift/FormValidatorSwift — Validation library that integrates with UITextField subclasses; commonly used with TextFieldEffects to add validation feedback to animated inputs.

Add Swift Package Manager example and documentation to README

The repo has Package.swift and .swiftpm directory structure indicating SPM support, but the README lacks installation/usage instructions for SPM. Currently only CocoaPods is implied. This is critical for modern Swift development and reduces friction for new users adopting the library.

• [ ] Add 'Installation' section to README.md documenting SPM setup (add to Package.swift dependencies)
• [ ] Document minimum iOS/Swift version requirements (check .swift-version file and Package.swift)
• [ ] Add example code snippet showing how to import and use a TextField (e.g., HoshiTextField) after SPM installation
• [ ] Verify SPM installation works end-to-end with the example

Create unit tests for individual TextField effect classes in TextFieldEffects/

The repo has 9 different TextField implementations (AkiraTextField.swift, HoshiTextField.swift, IsaoTextField.swift, etc.) but no visible test files (.xctest or Tests/ directory). Each effect should be testable for basic initialization, animation triggering, and state management. This improves code reliability and helps contributors understand expected behavior.

• [ ] Create Tests/ directory at repo root with TextFieldEffectsTests.xctest target
• [ ] Add test file TextFieldEffectsTests/TextFieldEffectsTests.swift with basic XCTest cases
• [ ] Write initialization tests for at least 3 effects (e.g., HoshiTextField, AkiraTextField, KaedeTextField) verifying UITextField subclass setup
• [ ] Add tests for placeholder label and animation state management (checking animated properties exist post-interaction)
• [ ] Update .travis.yml to run swift test or xcodebuild test

Add GitHub Actions workflow to replace Travis CI configuration

The repo uses outdated .travis.yml for CI/CD. GitHub Actions is now the modern standard with better integration, faster execution, and no external service maintenance. This reduces technical debt and improves visibility of build status directly in the repo interface.

• [ ] Create .github/workflows/swift-tests.yml with jobs for macOS (latest) running Swift tests
• [ ] Add matrix strategy testing against multiple Swift versions (5.1, 5.5, 5.9) if .swift-version supports it
• [ ] Include steps for: checkout, setup-swift, build (swift build), and test (swift test)
• [ ] Update README.md badge from Travis CI to GitHub Actions workflow badge
• [ ] Once verified working, optionally deprecate .travis.yml with a comment (retain until GitHub Actions passes consistently)

• Add unit tests for animation timing accuracy: The TextFieldEffects/TextFieldEffects/ directory has 9 effect files but no corresponding test files (none visible in the top 60). Create TextFieldEffectsTests/ with test cases that verify each effect's placeholder animation duration, CABasicAnimation keyframes, and color transition correctness using XCTestCase.
• Document each effect's IBInspectable properties in-code: Open AkiraTextField.swift, HoshiTextField.swift, etc. and add comprehensive inline documentation comments above each @IBInspectable property (e.g., /// Placeholder text color. Default is light gray.) so developers and Interface Builder users understand customization options without reading the source.
• Add a comprehensive example in the README: The README shows GIFs but lacks a Swift code snippet showing how to use effects programmatically. Add a 'Programmatic Usage' section with copy-paste examples for 2-3 effects demonstrating property configuration, delegate setup, and animation observation.

The TextFieldEffects codebase appears to be a well-maintained UI library with minimal security concerns. It's primarily a visual effects library for UITextFields with no network communication, database access, or complex dependencies visible in the file structure. The main recommendations are to verify the Package.swift dependencies, ensure the Swift version is current, and review TextField implementations for proper input validation. No critical vulnerabilities were identified, but best practices regarding dependency management and version pinning should be followed. The library itself does not handle sensitive data processing, reducing the overall security risk profile.

• Low · Outdated Swift Version File — .swift-version. The .swift-version file is present but its content is not provided. This file may contain an outdated Swift version that could lead to use of deprecated or vulnerable language features. The absence of version pinning in modern Swift Package Manager is preferred. Fix: Review the Swift version specified and update to the latest stable release. Consider using Swift Package Manager's version specifications in Package.swift instead of .swift-version file.
• Low · Missing Dependency Verification — Package.swift. The Package.swift file content was not provided for analysis. Without reviewing the dependencies, it's impossible to verify if any third-party packages have known vulnerabilities or security issues. Fix: Review Package.swift to ensure all dependencies are from trusted sources, use specific version pins rather than loose version constraints, and regularly audit dependencies using tools like 'swift package describe' and security vulnerability databases.
• Low · Legacy CocoaPods Configuration — TextFieldEffects.podspec. The presence of TextFieldEffects.podspec alongside Package.swift indicates dual dependency management. This legacy CocoaPods file may not receive updates and could be overlooked during security maintenance. Fix: Deprecate the CocoaPods podspec if Swift Package Manager is the primary distribution method. If maintaining both, ensure version consistency and security updates are applied to both.
• Info · No Input Validation Visible in Structure — TextFieldEffects/TextFieldEffects/*.swift. While the codebase consists primarily of UITextField custom effects (UI/visual library), without reviewing the actual implementation code of TextField subclasses, potential input validation issues cannot be ruled out. Custom text field implementations should validate and sanitize user input. Fix: Review all TextField implementation files (AkiraTextField.swift, HoshiTextField.swift, etc.) to ensure proper input validation, character filtering, and text encoding handling is implemented where applicable.
• Low · Demo Application Security Considerations — TextFieldEffects/TextFieldsDemo/. The included demo application (TextFieldsDemo) may not have security headers or protections configured if it communicates with external services. Storyboard files can also be vulnerable to manipulation. Fix: Ensure the demo application does not hardcode any API keys, authentication tokens, or sensitive data. Review Main.storyboard and LaunchScreen.xib for any embedded sensitive information. Add appropriate code signing and provisioning profile requirements.
