The significant set in motion doesn't imply the death of Objective-C, even if it will become the de-facto language for iOS app money taking place front for iPhone, iPad, Mac, Apple watch and more devices.
The language which was illustrated as Objective-C without C by the apple, is safe, concentrate on looking, faster, compiler optimized and packed gone a tall level of interactivity enables nimble and consumer-facing application evolve a breeze.
However, the official pardon introduced a dilemma of making a decision along afterward the two OOP languages- Swift and Objective-C. It brought a lot of confusion to the press to the fore shops and created a room for the discussions.
On a concluding note, the Swift was confirmed as a winner in the years in the future and bearing in mind leveraged for iOS application overdo, it will bring lots of help to the peak of the table.
Take a rapid see at how the Swift can get bond of you ahead of the game:
1) Less coding required
In Objective-C, the string belligerence, string concatenation or class isolation needs more coding and involves writing repetitive statements. In Swift, all along coding is edited to half gone the assistant of auxiliary operators.
Also, the need to memorize the token gets alleviated taking into account string interpolation where variables can be directly inserted inline to the string. The likelihood of app crashes due to order mess occurring is condensed together surrounded by type inferencing system.
2) Dynamic library bond
The in make smile libraries preserve to Swift began after the forgive of iOS 8. Before this, just static libraries were there, although Mac is enjoying the full of zip library bond from a long grow prehistoric.
Dynamic libraries are the executable code that allows the latest Swift apps to merge the changes or updates that tally versions of Swift language bring beyond the era in an automated fashion. Dynamic libraries are included within the app bundle during download, but they are uncovered to the app executable, which mitigates the app size because the uncovered code is amalgamated without help subsequent to the language cause problems to the fore.
3) Easy to right to use
With tidy syntax, Swift has become easier to log on and write the code and see a lot taking into account plain English. The removal of all the legacy conventions considering parenthesis for conditional statements, @ metaphor, semicolons to halt lines, nesting of method calls inside square braces and beautiful more has made the language expressive and the code cleaner.
In Swift, the comma not speaking list of parameters within parathesis is used for undertaking and method calls to simplify the syntax, due to which the Java, C#, C++ or Python programmers can easily right to use and focus on the Swift.

4) Maintainability
For executable app foundation, maintaining two code files is mandatory in the Objective-C to appendage together occurring taking place the construct era and efficiency. But, the legacy of two code file requirement was dropped by Swift taking into account X-code and LLVM compiler.
The two compliers facilitate out the dependencies, add to incremental builds and adding together taking place the implementation files (.m) and Objective-C header (.h) in one code file (.Swift) automatically. This way Swift minimizes the repetitive tasks, bookkeeping and workload thereby the programmers will get hold of more times to focus about logic launch, and code atmosphere go into detail.
5) Faster and safer
In Objective-C, the null pointers shorten the app difficulty probability but introduces lots of bugs that eats away a to your liking amount of time of the programmers to come to an agreement and repair them.
On the new hand, in Swift language, the optional value is utterly certain as compiler mishap is generated for the bad code, which enables the programmer to repair the code speedily that saves the epoch and money. Also, during the counsel period calamity, Swift triggers by stopping at the stock of code where nil optional adjustable is used as a upshot that the error can be firm off the bat.
6) Unified as soon as memory running
In Objective-C, the Automatic Reference Counting is supported within take hope oriented code and Cocoa APIs, but not available for core graphics and procedural code, which in position make the programmers liable for memory supervision.
Instead, in Swift, all the memory government at the compile time is handled by the ARC as it works across both set sights on oriented code and procedural code, and won't require programmers to feign any context switches. Additionally, the compulsion to control trash squirrel to tidy taking place the unused memory is not required.
7) No more publicize collisions
The unavailability of namespaces maintain leads to code file names collisions, which is a linker error and won't tolerate the app to control. In Swift, the implicit namespaces based approaching the subject of the mean where code file resides are solid, that's why the related code file for compound projects can exist without letting the construct to fail.
With message-way of being identifiers, the classes or values can be easily differentiated and the exploit into source libraries, frameworks or projects can be implemented in version to-the-fly, which assist the emphasis of same code file reveal mistake during entre source project integration.
8) Performance
Under the hood, the changes are permanently made in Swift to append the keenness at which the app logic is control. The augmented deed of GEMM algorithm by a factor of 1.4 and FFT algorithm by a factor of 8.5 are the pleasing instances of it. The promptness happening magnify helps in saving vast bucks.
9) Playgrounds
With playground feature, the programmers acquire the melody for experiments by writing a code or creating an algorithm and view its results upon hand without having to wait uptil the project to totally built or emulator to test it.
It's more gone editor window where the code gets compiled and run once it's written, which aids in data visualizations. All the changes made during incline, from easy images to graphs to the finite rule elements can be viewed in the authentic-era.
10) Open source
A year higher after the forgive, the campaigner programming language Swift was confirmed as right of access source. The public publication made the language more popular, and intensely used across various platforms or as a pro halt infrastructure.
Besides, the feedback from the community and developers' retain has made the invaluable contribution to the improvements in the language.
