Full Keyboard Control in UIKit Apps

on YouTube ↗34m

" summary

Explains how to add full keyboard control to UIKit apps using UIKeyCommand and the UICommand/UIAction/UIKeyCommand menu hierarchy, and how the responder chain collects possible commands then looks up a handler when a key combination is pressed. Shows a real PDF Viewer ported to Mac via Catalyst, a KeyboardKit library on GitHub, and implementations for tab switching, nav bar key equivalents, arrow‑key table navigation, and responder chain injection. Notes practical limits: no key‑release/hold events and function keys are unreliable.
