Us developers have learned the hard way that:
1. Prototyping is more like 10% of the actual work - even though the business folks thinks we're 90% done
2. Shipping prototypes to production is possible but generally a bad idea
Vibe coding is prototyping. Others will learn - soon

It can be difficult to find a clear, concise explanation of how method dispatch works in Swift, when calls are resolved statically or dynamically, and what that means for performance.

Like Trump, Tim Cook doesn’t need to care about education anymore. They and the rest of the gerontocracy will be dead by the time the results of their choices are fully realized. Our system rewards sociopathy. At least it’s inspiring revolution.

Using #SwiftUI’s UIGestureRecognizerRepresentable and Anchor Preferences, you can build a ButtonStyle that is triggered by a long-press in a parent view in addition to regular taps.
This enables building custom menus like this that allow triggering an action with a single long press.

Codable conformance for Swift enums has evolved over the years, with the compiler now handling much of the work automatically. I wrote a post about automatic conformance, customizing it, and writing fully custom encoding and decoding logic when needed: nilcoalescing.com/blog/Codable...

A really nice personal milestone to end 2024, Boutique crossed 1,000 stars on GitHub last night. I spent months building v1, two and a half years improving Boutique 2.x, and am very excited to launch 3.0 with Observable support and many new features in the new year. 🥳

Right, what should I use to cache a bunch of data that will update over time, and require fairly constant querying? SwiftData seems fine, but the whole “must use classes for instances of a model type" is pretty meh.
What other options do I have? Boutique, perhaps?

Does anyone know how to allow natural feeling scrolling with nested scrollviews in SwiftUI?
I have a vertical scrollview that *can* contain horizontally scrolling content at times - but the horizontal scrollview "eats" the vertical gestures.

I got a thing working! Multiple cursors for `NSTextView`.
Library is actually text system-agnostic and `UITextView` isn't too far behind. Not "done" quite yet, but quite far along. And has some of the pieces in place to support very large numbers of cursors.

I'm still working away at this slowly, but also I am on holidays from work so I fully intend to do very little but float around in the water a bunch 😊

I've spent the 6 months working on a new approach to shared data in Swift: Forked.
Main features:
- Git-like branching and merging for Swift structs
- Advanced merge algorithms (CRDTs)
- Macros to make structs mergeable
- Sync structs via CloudKit with <10 LOCs

Now we’re all Forked!
Forked is a new Swift framework for working with shared data, on device, and across networks.
