  • Manage iOS/macOS simulators with simctl and related tooling
  • Verify and inspect code signatures and keychain access
  • Manage Homebrew packages for development environments
  • Use case: A developer CI pipeline runs a full macOS dev workflow to validate a new feature across devices and sign artifacts.

Quick Start

Invoke ostwin mac devtools to automate common macOS developer tasks.

Frequently Asked Questions about developer-workflows

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate building Xcode projects and running tests?▼

You can automate building Xcode projects by invoking the ostwin mac devtools workflow, which uses xcodebuild and xcrun to reduce manual overhead in compiling and testing your code.

What's the best way to manage iOS simulators from the command line?▼

Managing iOS simulators is handled through the simctl tooling integrated into the macOS developer workflow, allowing you to automate simulator creation, booting, and shutdown for local testing.

How do I verify code signatures and keychain access in a CI pipeline?▼

Verifying code signatures and keychain access is automated using the codesign and security tools, enabling CI pipelines to inspect artifacts and maintain signing credentials without manual intervention.

Do I need Homebrew and Xcode command-line tools to automate macOS dev workflows?▼

Yes, automating macOS dev workflows requires Xcode command-line tools, Homebrew, and access to ostwin automation scripts to execute commands like xcodebuild, simctl, and codesign.

Can I manage Homebrew packages across local development environments?▼

Yes, managing Homebrew packages across local development environments is a core feature, allowing you to automate dependency installation and maintain consistent development setups.

Why does my macOS CI pipeline need manual overhead for codesign and simulator tasks?▼

Manual overhead occurs when tasks are isolated; this workflow automates the end-to-end process of building Xcode projects, managing simulators, and handling codesign tasks to streamline CI pipelines.
