Swift Deep Insight: Unused Code Detection

Detect unused (dead) code in Swift projects using the Swift compiler's index store.

Prerequisites

Xcode Projects

Build the project in Xcode first — the index store is created automatically at ~/Library/Developer/Xcode/DerivedData/<Project>/Index/DataStore.

SPM Projects

Build with xcodebuild -scheme <scheme> build or swift build.

Commands

Run from the project root or specify a path:

# Scan current directory
swift run swift-deep-insight --project-path .
