What is TextDiff?

TextDiff is a macOS Swift package that computes token-level diffs between two text strings and renders a merged, display-only view highlighting insertions, deletions, and changes. Drop in two strings via SwiftUI's TextDiffView or AppKit's NSTextDiffView, pick token or character mode for precision (like refining "Add" to "Added" by shared prefix), and get automatic layout with wrapping and intrinsic height. Perfect for macOS SwiftUI apps, tutorials, or tools needing a compact text diff checker without selectable text.

Why is it gaining traction?

It delivers pixel-perfect rendering with customizable styles—tweak colors, fonts, chip spacing, strikethroughs, and insets—while handling whitespace, punctuation, and multiline text neutrally. Updates trigger efficient recomputes only when needed, and both SwiftUI and AppKit share the same renderer for consistent chips around changed words. Developers grab it for the dead-simple API that slots into macOS SwiftUI sidebars, toolbars, sheets, or menus faster than rolling custom diffs.

Who should use this?

macOS app builders integrating diffs into GitHub clients (desktop, CLI, runners, or SSH key setup tools), changelog viewers, or editors. Suited for SwiftUI tutorial projects, SwiftBar menu apps, or any dev needing inline text diffs in macOS GitHub actions workflows or download managers.

Verdict

Solid early pick (15 stars, 1.0% credibility score) with crisp docs, previews, and snapshot tests covering edge cases—mature enough for production niches despite low traction. Use it now if macOS-native text diffs fit; watch for broader adoption.
