Answer 1

An overview of the language features for Swift 3 can be found at https://swift.org/blog/swift-3-0-released/ .

This specific change is part of SE-0006 Apply API Recommendations to the Standard Library :

The concept of "generator" is renamed to "iterator" for all APIs.

,

extension Sequence where Iterator.Element == Character {

}
