Swift Talk

A weekly video series on Swift programming.

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

#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.

#29 Protocols & Class Hierarchies 16:02

We refactor a class hierarchy using a protocol and discuss the differences between both approaches.
