SwiftUI AI chat components

A dark glass ball with a Siri-style voice wave inside, locked to the thinking state; four thin sine membranes travel through the equator of a refracting shell, drawn by a Metal color shader. The sphere never moves, only the wave, and a palette change crossfades its colours.

A code slab for chat replies and docs that stays dark in both appearances: a butter language label and optional filename, block-colored Swift syntax, collapse past N lines with a fade and a spring expand, wrap toggle, text selection, a streaming mode that fades lines in behind a cursor, and a copy pill that turns into a sage Copied block.

A snapping horizontal row of prompt suggestions above a composer, each chip keyed by a solid color block glyph. The chosen chip morphs into a composer-width block with matchedGeometryEffect while the rest slide out, then the row hands the text back and collapses.

The AI reply surface. A small header carries the assistant mark and a live phase label, text arrives token by token with a per-word fade and a color block cursor, inline code sits on butter blocks, user prompts are solid color blocks, and a long press lifts the message to reveal copy and regenerate.

The "assistant is working" placeholder, laid out like the reply it becomes: a breathing mark with an elapsed-seconds label over three presentations on one clock: block-colored rising dots, a sheen over reply-shaped bars, or a label whose glyphs carry the sheen. Plus a modifier that sweeps any view.

A small dark glass ball with a Siri-style voice wave inside, locked to the thinking state and drawn by a Metal color shader; palettes for searching, reading and writing crossfade the colour with the kind of work, and a Pill wraps it with a label and indeterminate dots into the status control.
