Avoiding a Swift NSRegularExpression Pitfall

Until Swift gets a native regular expression class of it's own we are stuck with the Objective-C version - NSRegularExpression. 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

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

Swift Struct vs. Class

I've been having a tough time in Swift with the Struct vs. Class issue. Unlike Java and Objective-C, Swift allows value type "classes" known as Struct types. These behave very similar to C++ objects that are created without dynamic memory allocation - in other words they're created on the stack instead of the heap. This … Continue reading Swift Struct vs. Class
