Here is another slow expression to demonstrate the disjunction pruning optimization I talked about earlier.

Suppose you declare a variable of implicitly unwrapped optional type:

var x: Int! = ...

The value of x is stored like an ordinary optional "Int?", but a reference to x from inside an expression is presented as a disjunction---the type of the reference is either "Int", or "Int?". If both lead to a solution, we favor the "Int?" choice; otherwise, we get the "Int" choice, and the compiler then lowers the reference to a runtime check.

Now, consider this expression:

let result = x + x + x + x + x + x

It takes the Swift 6.3 compiler a third of a second to type check this expression, and now its instant with recent main snapshots. What changed?

There are two problems in computer science:

1. We could do this better
2. We should not do this at all

I published a new article, "Introducing the Experimental Styles API in Jetpack Compose".

It introduces the Styles API as a new way to define interactive, stateful Compose UI with automatic animations and efficient style application.

When you email issues to Obsidian Entertainment (the video game company) their AI support hallucinates and tells you to email Obsidian (the note-taking company) instead.

The perils of trusting an LLM with your customer support.

The write-up of my new graph layout algorithm for SpiderMonkey is finally live.

We built a custom layout algorithm for JS and WASM that follows the structure of the source code. No more spaghetti nightmares from Graphviz, and thousands of times faster.
