In Swift 2.0, thanks to the power of protocol extension, some of the global functions have been converted into methods, particularly global functions that act on parameters of type Sequence or Collection. However, I do have some questions while going through my list of global functions:
- Why is that global funtions like dropFirst, dropLast, prefix, suffix and zip not converted into methods?
- Some global functions are also methods of Collection type, but not removed as global functions, for example: insert, join, removeAll, removeLast, removeRange, sort. Why?
Thanks!
