The Apple File System is still a slightly mysterious beast. Apple has reason to be cautious: A new file system is always a huge undertaking and the risks couldn't be higher: a serious bug can cause . . .
A brave new world
Xcode 8 now supports an official extension API. The first extension type supported is the Source Editor extension (though probably not the last). The flip-side is that Xcode 8 adopts System Integrity Protection. That means it is no longer possible to inject code into the Xcode process. Alcatraz is closed for business.

It's Unsafe Pointers All The Way Down
Today I want to do a small exercise in packing some
Float32s into a SQLite Binary Large Object (BLOB) column. Sure I could use JSON, protobuf, or some other encoding. Yes I could also use
NSCoder or plists.
Instead I want to do this purely in Swift and mostly analogous to what you'd do in C because . . .
It's rabbit holes all the way down
Associated Types Series
In my last article I gave an incorrect explanation for why Swift has associated types. It was half-correct in that specific knowledge of the types gives the compiler the ability to optimize but . . .
Sure, let's go down this rabbit hole again
Update: I originally hit publish too soon; this is the updated article.
I don't feel like I fully covered one aspect of protocols with associated types: why can they be such a pain to work with?
Why Associated Types
This rabbit hole just keeps on going; see my third article in the Associated Types series for a . . .
This is a no-bullshit zone
Let's learn what Monads, Applicatives, and Functors are, only instead of relying on obscure functional vocabulary or category theory we'll just, you know, use plain english instead.
Functors are containers you can call
map on. That's it. Seriously.
A million words of category theory and Haskell . . .
It's parameters all the way down
Update: You can read even more about type erasure with lots of example code
More specifically, what is type erasure in the context of . . .
