Mastering Swift 2 Programming (Video 49)

This video tutorial explains the concept of generic specialization in Swift, a compiler optimization technique that enhances the performance of generic functions. It demonstrates how to create and test both generic and non-generic methods in an Xcode project, and compares their performance. The video also covers enabling whole module optimization to further improve performance, showing that with this setting, generic functions can perform as efficiently as non-generic ones.
