Accessing an API using CoreData's NSIncrementalStore

Note: the original location of this article is on my blog, however, it is posted here too for better readability.

In this article, we will see how to use Core Data for accessing your API. We will use the Bandcamp API as our running example. I've only been experimenting with this code for a few days, so there might be mistakes in there.

  trait Pointed[P[_]] {
    def point[A](a: A): P[A]
  }

  trait PointedFunctor[PF[_]] extends Pointed[PF] with Functor[PF]

  implicit def listIsMonoid[A]: Monoid[List[A]] = new Monoid[List[A]] {
    def id: List[A] = Nil

    Action {
      // do something with stack
    }
  }

The Indexed State Monad in Haskell, Scala, and C#

Have you ever had to write code that made a complex series of succesive modifications to a single piece of mutable state? (Almost certainly yes.)

Did you ever wish you could make the compiler tell you if a particular operation on the state was illegal at a given point in the modifications? (If you're a fan of static typing, probably yes.)

If that's the case, the indexed state monad can help!
