Custom UIRefreshControl Animation

I’ve playing around with Swift in the last month, finally. I’m still an order of magnitude faster when writing in Objective-C, but so far I’m mostly enjoying what I see, so much that I started to use a mix of both languages in production. There’s still a lot of stuff that doesn’t work properly though, but it is to be expected. To test the waters I’ve built a simple app in Swift that uses Realm to share data between the main app, a Today extension and a WatchKit app. It’ll be open source, and I’m planning to write a blog post on our main blog in the next few days. In the meantime I just wanted to share a simple demo project that I wrote after stumbling upon this brilliant Dribble shot.

You’ll find the demo project with the implementation of that animation here.
