Create a Swift Dictionary from an Array

Here is a Gist I posted showing a Swift utility function that enables you to create a Dictionary containing an optional entry for every element in an Array. It uses the reduce function to create one Dictionary from every element in an Array, based on a closure you provide that turns an array element into a key-value tuple.

This code was compiled and tested against Xcode 6 Beta 3.

    I don’t think we should be creating this kind of thing for specific structs and classes; instead let’s make this an instance method of a protocol, and extend Array to implement it, as with C#:

      Let me know when you put together a sample of this, I’m curious to see your approach.
