Optimizing Swift code for separation of concerns and simplicity
summary
Shows concrete refactors: extract a utf16Count helper for why utf‑16 matters, move filtering into extensions, replace repetitive indexPath logic with a row enum, add a state enum to avoid optionals when loading profiles, and introduce layout helpers including custom operators and a TW_safeAreaLayoutGuide plus a reusable MinimumHitAreaButton. Demonstrates using an active-constraints array and stack views to toggle layout. Each change is implemented and tested in a real app codebase and measurably improves readability and reduces bugs.
