Liquid Glass, Motion and Flows

What shipped

• Every piece is liquid glass: buttons, chips, pills, toolbars, badges and indicators are glass shapes that merge through a neck when they come close, on Liquid Glass in iOS 26 and a frosted fallback from iOS 17.
• Anything that appears buds out of the shape that caused it and melts back in when it goes: a stop button out of a download pill, menu actions out of their trigger, a stepper's minus into its count at zero.
• Labels change letter by letter, glyphs blur from old to new and numbers roll.
• One font weight, semibold, across every piece, with size setting the hierarchy.
• One red: the brand red tints primary actions and selections, sage marks success and butter marks warnings.
• One motion language across every piece: five spring tiers and named roles for every moment something moves (press, release, settle, snap, rebound, morph, reveal, dismiss, success, error, ambient).
• More bounce everywhere: releases, landings, selections and reveals spring past their mark and settle, so nothing feels stiff. Presses still land firmly under your finger, and numbers and charts never overshoot.
• Drags track your finger with no lag, and a flick carries its speed into the release instead of starting from rest.
• Limits feel elastic: past an edge, cards, sheets, sliders and indicators move against the same resistance a scroll view has, then spring back.
• Presses sink by a few points rather than a fixed percentage, so an icon gives visibly and a card only slightly, and they lean toward where you touched.
• State changes play in order: the container changes shape first, the content swaps inside it, then the outcome lands with its haptic.
• Reduce Motion now substitutes rather than switching feedback off: settles lose their bounce, moving transitions become fades, presses dim, and loaders still show they are working.
• Each piece is still one Swift file. It carries a private copy of just the motion parts it uses, so installing one piece is still one file and two pieces never collide.
• The previews on every component page and in the docs now move the way the pieces do, on the same springs.
• New: Glass Mode Bar, one glass capsule of mode icons that turns into the mode you pick: a signal anchor buds out of its end carrying the mode while the capsule trades its icons for that mode's own controls, and the body keeps its footprint.
• New: Glass Quick Add, a Quick add pill that folds up into a card of capture kinds, then re-forms in place into the one you pick, with Save budding out of its corner only once there is something to save.
• New: Source Stack, the sources behind an AI answer. A pill of site badges opens into numbered source cards, the badges flying out of the stack into their cards. It replaces Code Block, which is retired.
• A new guide, SwiftUI motion, explains the springs, rubber banding, momentum, squash and stretch, and follow-through with code you can paste.
• Flows in SwiftPieces Pro: 48 complete journeys through its 12 app templates, screen by screen, from first run with sign-in and the paywall to the core of each app, profile and settings. Find them in the navbar's Library menu; the first three steps of every flow are open to everyone (see Flows in Pro below).
