Apple introduced nullability annotations to Objective-C compiler from XCode 6.3. I was really surprised by this change, and welcomed it with open arms when I saw the release notes.

Hopefully it will help anybody with similar issues and increase discoverability of the solutions.

Today I introduce a small Swift DSL to improve how complex and chained animation code looks, and reads.

I’ve gradually been changing my code style favouring (Obj-C) categories and (Swift) extensions a lot more. I’ve been inspired by my other lover (Ruby). Why? Readability and code organisation.
