Overview

Validation and quality enforcement for CocoaPods dependency management in iOS, macOS, tvOS, watchOS, and visionOS projects.

What This Jutsu Provides

Validation Hooks

• Podspec Validation: Automatically runs pod lib lint to validate podspec syntax, dependencies, and build integrity
• Quick Validation: Uses --quick flag for fast feedback during development
• Fail-Fast: Stops on first error to provide immediate feedback
• Smart Caching: Only re-validates when podspec or source files change

Skills

This jutsu provides the following skills for CocoaPods development:

• cocoapods-podspec-fundamentals: Creating and maintaining podspec files with required attributes, file patterns, dependencies, and platform specifications for iOS, macOS, tvOS, watchOS, and visionOS
• cocoapods-subspecs-organization: Organizing complex libraries into modular subspecs with proper dependency management and default subspec patterns
• cocoapods-test-specs: Adding automated tests to CocoaPods libraries using test specs that run during validation
• cocoapods-privacy-manifests: Implementing iOS 17+ privacy manifests (PrivacyInfo.xcprivacy) for App Store compliance
• cocoapods-publishing-workflow: Publishing libraries to CocoaPods Trunk with proper validation, version management, and best practices

Installation

Install via the Han marketplace:

han plugin install jutsu-cocoapods

Or install manually:

claude plugin marketplace add thebushidocollective/han
claude plugin install jutsu-cocoapods@han

Usage

Once installed, this jutsu automatically validates your CocoaPods code:

• When you finish a conversation with Claude Code
• When Claude Code agents complete their work
• Before commits (when combined with git hooks)

What Gets Validated

The hook runs in directories containing:

• .podspec files

And validates when these files change:

• *.podspec (podspec files)
• **/*.{swift,h,m,mm} (source files)
• **/*.xcprivacy (privacy manifests)

Validation Command

pod lib lint --quick --fail-fast

This ensures:

• Podspec syntax is valid
• Required attributes are present
• Source file patterns are correct
• Dependencies resolve properly
• Platform targets are compatible
• Resources are properly configured

Requirements

• CocoaPods: 1.12.0 or later (1.16.2 recommended for latest features)
• Xcode: 15.0 or later (for iOS 17+ privacy manifests)
• Ruby: 2.7 or later
• Git: For version control and publishing

Installing CocoaPods

# Using gem (recommended)
sudo gem install cocoapods

# Or using Homebrew
brew install cocoapods

# Verify installation
pod --version

Validation Workflow

Automatic Validation

When you make changes to:

1. Podspec files (*.podspec)
2. Source code (*.swift, *.h, *.m, *.mm)
3. Privacy manifests (*.xcprivacy)

The jutsu automatically runs validation when you stop a conversation or complete agent work.

Manual Validation

You can also run validation manually:

# Quick validation (recommended during development)
pod lib lint --quick

# Full validation (with build)
pod lib lint

# Validate for publishing
pod spec lint

Common Validation Errors

Missing Required Attributes

ERROR | [MyLibrary] Missing required attribute `license`

Fix: Add license to podspec:

spec.license = { :type => 'MIT', :file => 'LICENSE' }

Invalid Source Files Pattern

ERROR | [MyLibrary] The `source_files` pattern did not match any file

Fix: Update source_files pattern:

spec.source_files = 'Source/**/*.{swift,h,m}'

Platform Not Specified

ERROR | [MyLibrary] The platform attribute is required

Fix: Add platform deployment target:

spec.ios.deployment_target = '13.0'

Privacy Manifest Missing (iOS 17+)

WARNING | [MyLibrary] Missing privacy manifest for iOS 17+

Fix: Add privacy manifest:

spec.resource_bundles = {
  'MyLibrary' => ['Resources/PrivacyInfo.xcprivacy']
}

Skipping Validation

If you need to skip validation temporarily:

# Set environment variable
HAN_SKIP_HOOKS=1

# Or disable the plugin
claude plugin disable jutsu-cocoapods

Advanced Configuration

Custom Validation Options

Create han-config.yml in your project to customize validation:

jutsu-cocoapods:
  lint:
    command: pod lib lint --quick --fail-fast --allow-warnings

Platform-Specific Validation

jutsu-cocoapods:
  lint:
    command: pod lib lint --platforms=ios --quick

Best Practices

Podspec Structure

Pod::Spec.new do |spec|
  # Identity
  spec.name         = 'MyLibrary'
  spec.version      = '1.0.0'

  # Metadata
  spec.summary      = 'Brief description'
  spec.homepage     = 'https://github.com/username/MyLibrary'
  spec.license      = { :type => 'MIT', :file => 'LICENSE' }
  spec.authors      = { 'Your Name' => 'email@example.com' }

  # Source
  spec.source       = { :git => 'https://github.com/username/MyLibrary.git', :tag => spec.version.to_s }

  # Platform
  spec.ios.deployment_target = '13.0'
  spec.swift_versions = ['5.7', '5.8', '5.9']

  # Files
  spec.source_files = 'Source/**/*.swift'

  # Resources (use resource bundles)
  spec.resource_bundles = {
    'MyLibrary' => ['Resources/**/*']
  }

  # Dependencies
  spec.dependency 'Alamofire', '~> 5.0'
end

Pre-Publish Checklist

• All validation passes without warnings
• Tests are included and passing
• Privacy manifest included (iOS 17+)
• README is comprehensive
• CHANGELOG is updated
• Version is tagged in git
• License file exists

Troubleshooting

CocoaPods Not Found

# Install CocoaPods
sudo gem install cocoapods

# Or update
sudo gem update cocoapods

Validation Timeout

If validation takes too long, the hook will timeout after 3 minutes. To fix:

1. Use --quick flag (already enabled by default)
2. Skip tests during quick validation
3. Reduce dependencies
4. Check for slow network (dependency downloads)

Cache Issues

If validation fails due to stale cache:

# Clear CocoaPods cache
pod cache clean --all

# Re-run validation
pod lib lint
