Apple’s written interface-guideline lineage begins with drafts from 1978–79 and is approaching fifty years. The surviving trail runs from internal standards through printed books, platform-specific PDFs, and today’s living website.
This is a source catalog, not a claim that every edition ever circulated has survived. Dates follow the documents or archive filenames. External links point to the source copies; their presence here does not grant permission to reuse them.
Five measured transitions
The river is not one long expansion. Each neighboring pair marks a different turn in what Apple considered interface-design work.
1982 → 1987
Text becomes a desktop
Typed menus, sequential screens, and keyboard feedback give way to a mouse, windows, icons, and a persistent menu bar. The measured text grows from 11,000 to 37,000 words, even as its unusually detailed user-research method is compressed.
1987 → 1992
The desktop becomes a reference
The book nearly doubles and turns established desktop grammar into dedicated bodies of guidance for menus, windows, controls, icons, language, access, and a much fuller design process.
1992 → 2008
One interface lineage splits in two
The Mac keeps the desktop and rebuilds it for Aqua; the first iPhone guide sets aside overlapping windows and menus for a full-screen touch model. Together, the two guides nearly double the measured corpus again.
2008 → early 2025
The platform becomes an ecosystem
Accessibility becomes a core concern across every platform, input expands far beyond mouse and touch, and platform guidance becomes the largest new body of work. The end-to-end design-process chapter, however, disappears from today’s HIG.
Early 2025 → today
Standard components inherit a new physical grammar
Liquid Glass changes materials and everyday controls; Duo later adds vertical bars, reserved regions, and fold adaptation. The detailed comparison uses a partial early-2025 archive and the current HIG, with coverage limits stated explicitly. Read the detailed navigation comparison ↗
Available versions
40 surviving documents and live sources, in chronological order. “No reuse license stated” is deliberately literal: the source archive contains a copy, but does not include a license granting reuse.
Pre-release Apple II manuscript. DigiBarn's wrapper adds a Creative Commons notice, but its own terms say it cannot license third-party works; this site therefore does not republish the document.
Apple's living, continuously revised guidance. The river compares an incomplete early-2025 archive (150 archived pages) with the HIG as of September 19, 2026 (173 pages), spanning Liquid Glass and iPhone Duo. Archive coverage differs; the word totals do not establish full-corpus growth.
