Kuba Suder with a great article about the changes to location permissions coming in iOS 11. If your app currently asks for the "Always" permission without allowing "While using the app" then you're in for some work. From a consumer perspective, these tweaks are really great though. Location data is sensitive and we should be forced to be conservative with how we gather it.
I've already linked to the panel discussion that this post references back in Issue 306 but if you didn't get a chance to watch it, Ole Begemann's post of Chris Lattner's contributions on it is worth a read!
Did you know that you could insert a SpriteKit scene of any size into your regular UIKit view hierarchy? John Sundell shows us how if you need a little more power/flexibility for your animations.
Talking of animations, this looks very cool.
