Library of Apple’s interface guidance

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 ↗

Apple platformsWebsite

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.
