Similarly different: join(), reduce() and flatMap() in Swift 2
reduce(), flatMap() and join() can produce the same results. So what is the difference between the three and when do you use each one?
Every Swift Value Type Should Be Equatable
I've only been adding the Equatable conformance to my Value types when I need it in my code, but this is a great argument for making all of your values equatable right away, since that is the expected behavior for value types.
UPDATE: Tested the below, and there's no need to implement the version with the optionals - it just works! Thanks @rob_rix and @anatomisation.
The only missing thing from this article is something I had to learn the hard way - make sure to implement the equality for different variations of your value type as Optionals as well!
func ==(lhs: Place, rhs: Place) -> Bool { }func ==(lhs: Place?, rhs: Place) -> Bool { }func ==(lhs: Place, rhs: Place?) -> Bool { }func ==(lhs: Place?, rhs: Place?) -> Bool { }

We've Got You Covered
Code Coverage is definitely one of the most exciting additions to Xcode announced at this year's WWDC. @borkware takes a deep look into how (and if) it actually works. And while we're talking about code coverage, I love this simple note by @mpweiher: When Is My Unit Test Coverage Adequate?.
How to Highlight Your TODOs, FIXMEs, & ERRORs In Xcode
Ok, so you really shouldn't have TODOs, FIXMEs, & ERRORs in your code, but if you're coming onto a project that has these long-forgotten artifacts, it's a good idea to implement this script for creating actual warnings around them in Xcode, to make sure they're evaluated and taken care of. I also don't mind @NeoNacho use case for them - "use TODOs and a similar script while coding, move longer term things to GH issues after".

Swift Thoughts
Jurassic World was the first movie where the 3D technology actually enhanced my movie experience (and didn't just make me dizzy!). It felt like I was on a roller coaster at Universal Studio, and I loved it! Ever since then, I've started going to movie theaters more often just to get this 3D experience. In other words, the 3D technology is the new "killer feature" of movie theaters in the age where we can get any movie on demand in the comfort of our home.
This, of course, made me think of the question I'm sure we've all been thinking - what is that "killer feature" of the Apple Watch? Are we just all waiting for that one "killer app" to come along and make consumers go gaga for the Watch?
For me, the fitness tracking is that killer feature. I wear my watch wherever I go somewhere so I can get credit for it. But, as @ksegall points out, there might not be that one-size-fits-all killer feature or app for the Watch, and that's ok.
