OpenClaw Swift Logger Package (TDD): Build and Ship Reliable iOS/macOS Logging
This case shows how to use a test-driven workflow to build a reusable Swift logging package for agent-integrated iOS/macOS scenarios, then publish it with clear quality gates.

What it does
- Defines a Swift logger package API and validates behavior with tests before implementation.
- Applies red-green-refactor to keep package changes safe and incremental.
- Produces a reusable logging component that can be versioned and published.

Pain Point
Custom platform utilities are often built ad hoc, with weak test coverage and unclear release quality. This creates regressions when reused across iOS/macOS agent workflows.
Core value of this case
This case turns utility-package development into a repeatable engineering process: test-first implementation, explicit quality gates, and release-ready packaging. The result is higher reliability for downstream integrations.
Typical scenarios
- Building internal Swift utilities shared across multiple Apple apps.
- Creating agent-side helper libraries that must remain stable over iterations.
- Shipping SDK-like components where behavior consistency is critical.
How to setup
- Define package API contracts and expected logger behavior in tests.
- Implement minimal code to satisfy failing tests, then refactor with tests green.
- Add release gates (tests, lint, docs) before tagging and publishing.

FAQ
Why use TDD for a small utility package?
Because shared utility code spreads quickly; test-first discipline reduces regression cost later.
Is this limited to logging packages?
No. The same workflow applies to any reusable Swift package with stable API expectations.
What are minimum release gates?
At least passing tests, lint checks, and basic API documentation before version tagging.
