Bootstrap iOS

Use this as the single entry point before touching an Apple-platform app. It is a router skill: discover the project, load only the references needed for the current job, verify that build/test tools exist, then act.

The default posture is conservative:

• Build and test before judging code.
• Prefer modern Swift, SwiftUI, Observation, Swift Concurrency, Swift Testing, SwiftData, and current Xcode APIs.
• Avoid deprecated APIs unless the deployment target requires them.
• Use XcodeBuildMCP or an agent-friendly build script instead of raw, unfiltered xcodebuild output when possible.
• Load focused skill packs on demand. Do not dump every Swift rule into context.
