since its release, every move by Apple has demonstrated its commitment to aggressively promoting Swift.

3. Version
- Official version 2.0 Xcode 7.0.1
- Beta version 2.1 Xcode 7.1 3
4.Swift features
- Apple claims Swift is characterized by fast, modern, secure, interactive, and significantly better than objective-c language
- You can use the existing
Cocoa and Cocoa Touch framework
取消了 Objective-C 的指针use of Swift and other unsecured access- Discard objective-c Early application
Smalltalk syntax and change to period notation
- Provides Java-like namespaces (
namespace ), generics ( generic ), operand overloading ( operator overloading )
- Swift is simply described as "objective-c without C" (Objective-c without the C)
5.Swift Status
- At present, some of the new projects in domestic companies have been directly developed by Swift
- Many companies are now working on Swift's talent pool.
- When applying, Swift development will undoubtedly increase its own chips
6. Why learn Swift?
- Since April, Apple has provided no OC for the information, which suggests that Apple's determination to drive Swift
- OC originated from
smalltack-c , has been more than 40 years of history, although OC the project will continue for some time in the future, but also for the Swift future inevitable trend
- Now many companies pay attention to the talent reserve, if swift, employment will have a great advantage, if the resume will be swift, although the interview although not how to be asked, but for the salary increase is very helpful, but also from another side can prove that we are self-learning ability of people, this is what all enterprises need
- Swift incorporates a lot of other object-oriented language ideas, not as closed as OC, learning Swift, and then other languages will be much easier
- Swift is also born from Apple, the overall process of development thinking and OC is the same.
7. Recommendations
- Objective-c & Swift Comparative learning can have a deeper understanding of many of the underlying principles of Apple's implementation
