Problem

PR #59 "Fixing Transport Tab" lacks comprehensive documentation explaining what specific issues were fixed and how the solutions work.

Missing Documentation

1. PR Description

• Current: PR title is simply "Fixing Transport Tab" with minimal description
• Needed: Detailed explanation of:
  • What specific transport tab issues existed
  • What symptoms users experienced
  • How the fixes resolve each issue
  • Testing methodology used to verify fixes

2. WATCHCONNECTIVITY_DIAGNOSTICS.md

• Added: 251 lines of new diagnostic documentation
• Status: Not reviewed in detail for accuracy
• Concerns:
  • Need to verify technical accuracy of explanations
  • Ensure troubleshooting steps are complete
  • Confirm the "Asymmetric Reachability" behavior is correctly characterized
  • Validate the "isPairedAppInstalled Degradation" root cause analysis

3. Local.xcconfig.example

• Current: Good inline documentation exists
• Enhancement Needed: Add section to main README.md explaining:
  • Why Local.xcconfig is required
  • Setup steps for new developers
  • Common issues and solutions
  • Link to Local.xcconfig.example
