The Objective-C version is very capable and works very well but it's important to remember that it is working on Objective-C NSStrings which, unlike Swift's native Strings, are based on the UTF-16 encoding. What this … Continue reading Avoiding a Swift NSRegularExpression Pitfall

Swift Property Wrappers
From now on with each new version of Swift that comes out I'm going to take some time a dig through all the Swift Evolution Proposals that made it into that release.

Fastest Way To Get The Time
So, for my 6502/6510 emulator project I've been trying to figure out the best (read that, "fastest") way to get the time with nanosecond resolution. I need this because the North American version of the Commodore 64 ran at 1.02MHz (1,022,727Hz) and so that means the clock "ticks" every 977.8 nanoseconds. And that's just for … Continue reading Fastest Way To Get The Time

SwiftSyntax
I am really going to have to start playing around with the SwiftSyntax library! It looks like I'd be able to write some real code timesavers with it.
