Optimization of Swift Protocols
R. Barik, M. Sridharan, M. K. Ramanathan, M. Chabbi
Swift, an increasingly-popular programming language, advocates the use of protocols, which define a set of required methods and properties for conforming types. Protocols are commonly used in Swift programs for abstracting away implementation details; e.g., in a large industrial app from Uber, they are heavily used to enable mock objects for unit testing. Unfortunately, heavy use of protocols can result in significant performance overhead. [...] [PDF]
