Visualizing the Structure of a Swift Project
summary
Parses Swift source with SwiftSyntax to extract concrete structural dependencies — inheritance, usage (parameters, locals, casts), and aggregation — and reads the Xcode project file to map files into groups and targets. Builds a tool that renders an interactive node-link hierarchical layout with container nodes (groups and source files) that expand and collapse, computes positions so edges flow downward, shows metrics like cumulative component dependency, incoming/outgoing counts, tags and history, and demos opening nodes and tracing unexpected coupling.
