Task ID​

Format: E\{epic\}:S\{story\}:T\{task\} Value: E6:S06:T03

Overview​

This task investigates and resolves the Apple SDK license blocking issue that prevents proper installation or usage of ai-dev-kit components on Apple platforms (macOS, iOS). The investigation will identify the root cause and implement appropriate solutions to ensure Apple platform compatibility.

Task Objective​

Investigate Apple SDK license blocking issues, identify root causes, and implement solutions to enable proper ai-dev-kit installation and usage on Apple platforms.

Progress Log​

2026-03-10 - Phase 1 Complete: Code Analysis and Solution Implementation​

Completed Activities:

  • Comprehensive codebase analysis - No Apple SDK dependencies found in ai-dev-kit itself
  • Root cause hypothesis identified - Git operations on macOS trigger Xcode Command Line Tools requirements
  • Enhanced error handling implemented - AppleSDKLicenseError exception created
  • Git submodule backend updated - Apple SDK prerequisite checking and error detection
  • Install command updated - Apple SDK error handling integration
  • Apple platform setup guide created - Comprehensive user documentation
  • Investigation report completed - Detailed Phase 1 analysis and findings

Key Findings:

  • ai-dev-kit is platform-agnostic Python code with no direct Apple SDK dependencies
  • Apple SDK license blocking likely stems from Git operations requiring Xcode Command Line Tools on macOS
  • Issue manifests when Git backends (submodule/subtree) are used on macOS systems without proper Xcode setup

Implemented Solutions:

  1. Enhanced Error Detection: AppleSDKLicenseError with specific error messages and recovery suggestions
  2. Prerequisite Checking: Automatic detection of Xcode Command Line Tools on macOS
  3. User Guidance: Comprehensive setup guide with step-by-step instructions
  4. Alternative Paths: Package manager backend recommendations when Git operations fail

Next Phase: Phase 2 - Live testing and user feedback collection when terminal issues resolved

Success Criteria​

  • Issue successfully analyzed through code review
  • Root cause hypothesis identified (Git operations trigger Apple SDK requirements)
  • Solution implemented (enhanced error handling and user guidance)
  • Solution tested and validated on Apple platforms (blocked by terminal issues)
  • No regressions on other platforms (pending testing)
  • Documentation updated with Apple platform guidance

Input​

  • BR-040: BR-040-apple-sdk-license-blocking-issue.md
  • Platform Documentation: Apple SDK licensing requirements and restrictions
  • Installation Logs: Existing install logs from Apple platform users
  • Error Reports: User reports of Apple SDK license blocking

Deliverable​

  1. Investigation Report: Detailed analysis of the Apple SDK license blocking issue
  2. Root Cause Analysis: Identification of specific licensing requirements and conflicts
  3. Solution Implementation: Code changes or configuration updates to resolve the issue
  4. Testing Results: Validation that solution works on affected Apple platforms
  5. Documentation Updates: Apple platform installation and usage guidance

Acceptance Criteria​

  • BR-040 investigation phase completed with clear findings
  • Root cause documented with technical details
  • Solution implemented according to investigation findings
  • Apple platform testing confirms issue resolution
  • Cross-platform testing confirms no regressions
  • Documentation updated with Apple-specific guidance

Dependencies​

Blocks​

  • Apple Platform Users: Cannot use ai-dev-kit on Apple platforms until resolved
  • Installation Workflows: Installation fails on Apple platforms
  • CI/CD Pipelines: Apple platform builds may fail

Blocked By​

  • Investigation Results: Need investigation results to determine solution
  • Platform Testing: Need Apple platform testing to reproduce issue
