Curtis Herbert on using universal links to have a completely native password reset inside an app, while at the same time not breaking the web password reset experience if the app wasn't being used. This simply makes a better user experience for everyone. Universal links really are a great feature.
Mike Swanson on the possibility of enabling drag and drop between split screen apps on an iPad. I think copy and paste with UIMenuController is probably going to be the preferred way to implement this as drag and drop on an iPad can be slightly awkward. However, I really liked that he was able to get this up and running as a proof of concept.
Alright so quick actions with 3D touch are super easy. How about peek and pop? Not quite as simple but if you're looking for a guide on how to get started with it then Hector Matos has a great walkthrough for you.
There are two other posts on 3D touch which were published this week and are worth checking out. First up is Ryan Nystrom talking about 3D touch inside Instagram. Then there's some code by Instapaper covering how to override the default actions presented by a peek gesture in SFSafariViewController.
Paulo Faria with a pure Swift implementation of some of Go's concurrency features, based on libmill. The syntax is very simple and the concept of channels is interesting too. I'd not pay much attention to the performance claims though. Unless you're doing an enormous amount of concurrency I'd be surprised if GCD is your bottleneck.
While we're on the subject of Swift wrappers of C libraries, Colin Drake has written up an article this week on the process of getting it done.
