I just built a markdown-style editor for iOS that is highly performant with files of 5000 lines.

Every keystroke is restyled in under 8ms: no debouncing, no delayed rendering. 20 rapid keystrokes are processed in 150ms with full restyling after each one. Tag and boolean searches complete in under 20ms. Visible-range rendering is 25x faster than full-document styling. 120Hz screen refresh supported.

App file size is 722 KB.

If I can do it on iOS then it's must be 10x easier on macOS.
