Facets of Swift, Part 5: Custom Operators
Custom Operators are definitely a very controversial part of the Swift language. After all, it can create very unreadable code when taken to the extreme! And what happens when two external libraries have the same custom operator? While I was personally closed to the idea of custom operators initially, after reading and seeing a few demoes, I'm open to using them very sparingly and carefully in my code. My favorite example is using a ~> operator for background threads.

Swift Thoughts
I'm still waiting on my iPhone 6. I actually got a 6+ for testing, since it is the most different from my current iPhone. To be honest, I've been pretty slow to upgrade because I have small jean pockets.
However, last week, I met with @heymarcbrown, the organizer of the Swift Brooklyn Meetup, who's been using an iPhone 6, and he mentioned that he now expects all apps to have swipe-to-go-back functionality.
While iPhone 6 might not seem like that big of a change from iPhone 5, it actually is a substantial change that requires us to adopt new user interactions in our iOS apps. Just adding auto-layout to an iPhone 5 app is not enough.
