Dumpy
A native iOS app for analyzing Mach-O binary files. Built with a C parsing engine and SwiftUI interface.
Dumpy lets you import any Mach-O binary — executables, dylibs, frameworks, object files — and inspect its structure: Objective-C metadata, Swift types, load commands, segments, symbols, and more.

references
• Swift Type Metadata — Structs, classes, and enums from __swift5_types / __swift5_fieldmd sections
• Class Dump Generation — Reconstructed
@interface declarations with syntax highlighting, search, and export
• Search — Debounced cross-tab search across classes, methods, properties, and protocols
