Kyle Sluder with a great article on contentInset in a UIScrollView. There are some very interesting ideas here, I hope they made it into a Radar too!
Michael Armstrong with an implementation of ActiveRecord in Swift. It's early days with this so if you want something along these lines that you can ship today then don't forget MagicalRecord which will still work with Swift, like any Objective-C code does. This might be one to watch for the future though.
Great article on the transition from old iCloud to CloudKit in 1Password. It's been several months now since CloudKit was unveiled and the community is remarkably thin on horror stories about it, great news! Me? I'm sticking with Dropbox for syncing of something this important, for now.
