Getting started was just a bit challenging:
- I had done a bit of Mac programming, but had to learn a lot of new topics. Thankfully I am proficient in Swift and many ideas from iOS transfer over easily.
- Had a false start when I began building a wizard-like interface for composing a query. Although a lot of fun, this proved to be a lot more challenging than I'd like a side-project to be.
But I had a very rough and limited prototype up and running in a couple of weeks.
