Swift Talk 440 Keeping Local View State in Sync We explore the pitfalls of keeping local view state in sync using the date picker component from last week.

Swift Talk 439 Optional Bindings We explore different ways to create a binding to an optional value, and they can be pretty tricky to get right. This episode is public, enjoy! 😊

Swift Talk 438 Attribute Graph (Part 10) We add a padding layout modifier and, noticing a problem, revisit how we calculate view geometries.

Swift Talk 437 Attribute Graph (Part 9) We wire-up our layout modifier to use a fixed frame layout built on top of it. This begins to seem circular, but laziness saves the day.

Swift Talk 436 Attribute Graph (Part 8) We create our own version of the View protocol to generate the attribute graph automatically.

Swift Talk 435 Attribute Graph (Part 7) We reimplement our attribute graph’s layout protocol and use an HStack to generate the layout computer.

Swift Talk 434 Attribute Graph (Part 6) We extend our attribute graph to compute view frames and a display list for all views.

Swift Talk 433 Attribute Graph (Part 5) We construct the attribute graph for a simple SwiftUI view, and step through the graph’s updates as inputs change.

Swift Talk 432 Attribute Graph (Part 4) We add visualization support to our reimplementation of the attribute graph, using the Graphviz command-line tool to generate images for evaluation snapshots.

Swift Talk 431 Attribute Graph (Part 3) We make sure to re-evaluate nodes in the graph that are marked as dirty, only re-executing the bodies of our rules when inputs change.

Swift Talk 430 Attribute Graph (Part 2) We add dependency tracking to our attribute graph, which should update automatically every time we access the value of a node.

Swift Talk 429 Attribute Graph (Part 1) We start reimplementing the attribute graph, a data structure that tracks dependencies in SwiftUI’s view tree. This episode is free to watch, enjoy! 😊

Swift Talk 428 Swift 6 Concurrency (Part 5) We make our database actor work with SQLite's non-isolated APIs.

Swift Talk 427 Swift 6 Concurrency (Part 4) We add a persistency layer to our macOS app using an actor, and run into several concurrency errors.

Swift Talk 426 Swift 6 Concurrency (Part 3) We use the common SwiftUI reader pattern to take a snapshot of the web view, a much simpler solution than before.

Swift Talk 425 Swift 6 Concurrency (Part2) We add a web view to our macOS app and try two ways to take a snapshot asynchronously.

Swift Talk 424 Swift 6 Concurrency (Part1) We build a macOS app to explore Swift 6's concurrency features, and compiler errors. This episode is free to watch, enjoy! 😊

Swift Talk 423 Particle Effects (Part 6) We finalize our particle system by making it generic, and add a heart effect.

Swift Talk 422 Particle Effects (Part 5) We improve our particle system to animate multiple instances at once, and make sure to clean-up old particles.

Swift Talk 421 Particle Effects (Part 4) We refactor the particle system, combining canvas-based drawing with a keyframe timeline to drive the animation.
