# Swift Blast Radius

> Compute the dependency blast radius of a Swift or Objective-C file — direct dependents, one hop of transitive callers, and covering tests — from Xcode's pre-built index. Use this when planning a refactor, scoping a structural change, or sizing the impact of editing a shared file, before reading anything.
