<div>Thanks for the help. I've been involved in C, but never really got 100% into OOP. I pretty much finished PHP but probably wouldn't remember the complex parts if my life depended on it. </div>
<div><br>
</div>
<div>Swift is...different. After getting PO'd at an academic (dude wasn't all too great at his job as an instructor) said that scripting languages and compiled languages will never converge, and yet here we are. </div>
<div><br>
</div>
<div>Again, really appreciate the support, and will continue the work tomorrow. </div>

The module is Cairo. Do I need to change something (I'm assuming by struct you mean the name of the class containing wrappings). The class is named Cairo as well. Could renaming the module to ModCairo fix this?<br>

<div>I went and looked at it, and even now it looks like I want to take every function I've used in Cairo and translate it to Swift. Swift is such a...simple language compared to everything else. That being said, as a result of the specs, it is also much more
verbose in terms of writing the code. Compared to other languages, it is written out instead of shoved onto a few lines. </div>

<div>I’ll go ahead and comment it, but I think it’s simplistic enough that it should be readable with a grasp of some Swift concepts. Perhaps it’s a good idea to look through The Swift Programming Language to figure out some of the constructs I used — they’re
fairly basic constructs.</div>
