They used to release things where you see they put a lot of thoughts into it. Now they are half baked. This isn't so much a problem on Apps ( The Product ) where it is constantly being updated and tweaked. But with code you have the hassle to try and keep up. And the pace of improvement is very very slow. To put things into perspective, Swift UI has been development for 4 years. Not exactly the state of things I would like it to be.

Apple also isn't dogfooding much with Swift. And I think that is great. In many ways I starting to feel Swift is like Dylan [1], it is new, it is exciting, and it is fun. But somehow after nearly 6 years Objective-C stills feels better. The syntax may still be god damn awful, but it is small enough to be called elegant. While Swift felt like C++ with better Syntax.

You can change state without all the annoying purely functional programming stuff ([... previousState, newValue]). Just change it.

You can change a prop passed in and even pass a new value up to the parent. So you know the pass a function down so the child can change a value in the parent? Just pass the variable you want changed down with @binding.

In fact, most of the time I found myself staring at a “type too complex, add annotation” error. That one doesn’t actually mean your type is too complex, it just means you’re passing the wrong thing somewhere and instead of a useful error message the compiler just gave up and broke.
