#32 Array, ArraySlice & Collection (Collections #1) 15:16

We show how to make an extension on array available to other collections: first, we implement it for array slices, then we implement it as a protocol extension for all collections.

#37 Custom Collections: Building IndexSet 18:52

We take a look at how to implement a custom collection type. As an example, we build a simple IndexSet implementation. In upcoming episodes we'll make this type conform to collection protocols.

#41 Custom Collections: IndexSet as Collection (Collections #6) 16:51

In this final episode of our collection series, we make our custom IndexSet collection type conform to the Collection protocol, implementing a custom index type along the way.

#38 Custom Collections: IndexSet as Sequence 14:08

In this episode, we make a custom collection conform to Sequence. This allows us to efficiently iterate over the elements, and we gain all the useful functionality of Sequence.

#64 Driving Table View Animations 30:24

We build a component similar to NSFetchedResultsController, but without the reliance on Core Data. This component can be reused whenever we need to drive table view animations.

#69 Reactive Data Structures: Arrays 30:55

We build a reactive array type on top of the reactive list from episode #67 and implement a filter method.

  3. Structs
  4. Types

#67 Reactive Data Structures: Linked Lists 25:58

We build a reactive linked list on top of reactive programming primitives. We implement a reduce method on this type, which does the minimum amount of work when the underlying data changes.

#33 Sequence & Iterator (Collections #2) 16:54

We continue to make the collection extension from the last episode more generic: we implement it on the Sequence protocol and discuss infinite sequences in the process.

#35 Sorted Arrays (Collections #3) 16:42

We look at extracting a sorted array type in order to increase code clarity. We'll also make it conform to Collection.

#55 Sorted Arrays with Binary Search 26:51

Károly joins us to improve our sorted array implementation from episode #35 using binary search. We benchmark both implementations to learn about their real-world performance.
