xcode▌

Build and manage iOS/macOS projects using native Xcode CLI tools instead of MCP servers.

Use this skill to produce a repeatable Xcode build baseline before anyone tries to optimize build times.

Use this skill for project- and target-level build inefficiencies that are unlikely to be solved by source edits alone.

Use this skill as the recommend-first entrypoint for end-to-end Xcode build optimization work.

Check build environment BEFORE debugging code. Core principle 80% of "mysterious" Xcode issues are environment problems (stale Derived Data, stuck simulators, zombie processes), not code bugs.

Build and export iOS/macOS apps with xcodebuild for App Store Connect upload. \n \n Handles both iOS (IPA) and macOS (PKG) builds through archive and export workflows with xcodebuild \n Requires valid signing identity, provisioning profiles, and Xcode command line tools configured \n Integrates with asc CLI for uploading builds; macOS uploads require explicit version and build number parameters \n Build numbers must be unique and higher than previous uploads; includes commands to check existing

Use this skill when you need to build an app from source and prepare it for upload to App Store Connect.

Use this skill to implement approved build optimization changes and verify them with a benchmark.

Use this skill when compile time, not just general project configuration, looks like the bottleneck.
