Which are new Feature in Swift? [on hold]

1:

Swift is, in large part, a reimagining of the Objective-C language using modern concepts and syntax. During its introduction, it was described simply as "Objective-C without the C".

2:

Swift does not create pointers and other unsafe accessors by default, contrary to Objective-C which makes widespread use of pointers to refer to objects, as well as their traditional use in embedded C-language code, although pointers can be created explicitly.

3:

Additionally, Objective-C's use of a Smalltalk-like syntax for making method calls has been replaced with a dot-notation style and namespace system more in common with other modern languages derived from C, like Java or C#.

4:

Swift introduces true named parameters and retains key Objective-C concepts, including protocols, closures and categories, often replacing former syntax with cleaner versions and allowing these concepts to be applied to other language structures, like enums.
