Swift, you’ve changed so much

During the crazy week of WWDC 2014—right after the announcement of Swift—I decided to spend a little time trying to implement a quick weather app using the new language. I managed to wrap it up in a few hours (and spent way too much time trying to figure out how to parse JSON with a generically-typed dictionary) and open sourced it. There it sat for all these months while several versions of Swift were released. I’ve started my latest project with Swift and decided I should upgrade this project just to see how much has changed. I’m a professional procrastinator, do not try this at home.

I kept all the changes required to get it working again in a single commit. This gives a pretty good look at how much has already changed. I originally wrote this with an Objective-C mindset, so the patterns here are quite ugly. Still, I find it pretty fascinating.

As I mentioned above, I had a hard time last summer getting my JSON parsed and resulted in taking two different approaches—one with NSDictionary and one with Dictionary. This time around I decided to test out Argo, a library for parsing JSON objects.
