Swift by Sundell John Sundell

Adam Bell returns to the show to talk about animations, both how to make great use of the built-in animation tools that the iOS SDK ships with, but also how to drive custom, gesture-driven animation logic and the sort of performance optimizations that are typically required when writing that sort of code.

Brent Simmons returns to the show to discuss multi-threading and concurrency, and how to make good use of tools like Grand Central Dispatch. Also, building NetNewsWire in the open, the current state of SwiftUI, and the type of responsibilities that senior developers typically have.

Benedikt Terhechte returns to the show to discuss the pros and cons of using technologies like Catalyst and SwiftUI to build Mac apps, and also to share tips and tricks on how to use AppKit for use cases that Apple’s more modern frameworks do not yet support.

Donny Wals, book author and iOS developer at Disney Streaming Services, joins John to give practical tips on Combine and Core Data. How to manage and test increasingly complex Combine pipelines, and how come the opinions on Core Data are so divisive? Also, working on internal SDKs and frameworks, and taking a pragmatic approach to unit testing.

Kaitlin Mahar, lead engineer at MongoDB and member of the Swift Server Work Group, joins John to discuss the current state of server-side Swift, designing APIs for server-side libraries, and Swift’s upcoming suite of structured concurrency features.

David Smith, creator of apps like Widgetsmith, returns to the show to discuss whether SwiftUI is currently capable and stable enough to build production-level apps, and what sort of things that can be good to keep in mind when starting to deploy SwiftUI in production.
