SPM Build Analysis

Use this skill when package structure, plugins, or dependency configuration are likely contributing to slow Xcode builds.

Core Rules

• Treat package analysis as evidence gathering first, not a mandate to replace dependencies.
• Separate package-graph issues from project-setting issues.
• Do not rewrite package manifests or dependency sources without explicit approval.

What To Inspect

• Package.swift and Package.resolved
• local packages vs remote packages
• package plugin and build-tool usage
• binary target footprint
• dependency layering, repeated imports, and potential cycles
• build logs or timing summaries that show package-related work
