Magic Words – Harnessing the Power of TextKit
summary
TextKit is presented as the practical stack that makes rich editable text, custom layout and inline media possible: code uses NSTextStorage, NSLayoutManager, NSTextContainer to build a multi‑column magazine with exclusion paths, place images, and attach embedded audio attributes (and guitar chord callouts) to ranges. A working demo in Objective‑C shows glyph mapping, layout manager delegates and custom text storage, but UIKit integration is fiddly — UITextView delegate callbacks can be unpredictable and getting it robust takes a lot of extra work.
