Access control basics in Swift — Sometimes, when looking at a class or method you’ll see some modifiers in front of your declarations that look like this: Just kidding. They’ll actually look like this: final class JusticeLeague { private func saveTheDay() {} static func punishCriminals() {} } Final, private and static. You may have some idea…

We’re gonna take a break from talking about ReaktiveKit and Bond this week. I went down kind of a rabbit hole there with building our own Event and Observable classes, so this week we’re gonna go off topic a bit and talk about subscripting in Swift. We use subscripts in…

Observable properties — If you’ve been following along my last couple of posts, I’ve been writing about how to use curried functions to implement the Target-Action pattern and create an Event class. This post will draw everything together, and show how to create observable properties on a class. If you haven’t checked out…

A lot of my writing about code involves the smaller aspects of building an app. Things like cool frameworks, idiomatic Swifty things. Not a mention of the overall way to structure a project.
