Could you build this?
Partial A basic file diff viewer is simple, but building a production-grade macOS native 3-way merge tool with binary comparison, memory-mapped large file indexing, and Git integration is complex.
What it would actually take: A proper solution requires Swift/Objective-C using efficient diffing algorithms (like Myers diff or patience diff) optimized with C extensions, memory-mapped file viewing (mmap) for multi-gigabyte files, and deep integration with libgit2. The hard part is performance and syntax-aware diffing across massive files and edge-case conflict resolution during 3-way merges without UI freezing. This necessitates strong systems programming and desktop performance optimization skills.
