Swift has changed the course of iOS app development industry. The language has opened new doors to entrepreneurs to make their idea work which was impossible for a long time. 

Earlier iOS app development used to be time-consuming, difficult and the frequency of app crash was higher. 

Before Swift, app development was mostly done with Objective-C, a subset language of C with added object-oriented features to it but app development using Objective-C was tough. 

Owing to the concise yet expressive syntax Swift, helps in developing iOS app easily. Advantages of using Swift for iOS app development do not end there. Have a look at the top reasons why most of the mobile app development companies in India and all over the world uses Swift.

Statistics About Swift that you must know!


  • Swift has been awarded the 8th place as the most famous programming language in the year 2019
  • Programmers love Swift. Swift  is 6th when it comes to languages loved by programmers
  • Swift pays well compared to other app development languages. Swift developer gets an  average of $54-57k per annum
  • TIOBE and PYPL index cements the fact that Fame and usage of Swift language is rising year by year

1. Easy to Code 


Programming languages used in app development demands high and complex command lines for intricate solution. Swift, on the other hand, is concise and can reduce LOC making programming more efficient and faster.  Since fewer lines of codes are required for complex tasks, code reusability is high and thus a lot of time is saved since developers can remember which part of certain code can be used without any change in another part or even project.

2. Maintenance


Objective-C formerly used for iOS app development extensively had one big problem. The ability of the language to evolve was a tough task since it was a subset of language C and can only evolve after the language C.  Owing to the same reason iOS app developers had to maintain two files to improve build time and efficiency.

On the other hand, Swift combines the Objective-C header (.h) and implementation files (.m) to a single code file (.swift.).  Another biggest flaw of Objective –C was that we have to synchronize method names and comment between files manually. In this situation, Swift programmers can utilize this time to create app logic and improve the quality of their code, etc.

3. Data Management 


Another area where Swift wins is its ability to manage data at a faster pace. Swift uses LLVM for optimized native codes and operating platforms. Developers get the opportunity to rewrite several groups as structures.  As a result, the tasks take less time than Objective C. 

4. Highly Interactive 


One of the biggest benefits that Swift offers to any mobility service provider company is that it can work in an interactive environment and the developers can see the output while coding. It means that any error in coding can be seen and rectified in the coding stage itself. If you have any loops in code that you are writing, you can see it in the timeline panel where variables are being calculated.

5. Lightning Speed


Swift has one of the fastest algorithm calculation metrics and the operations for the language is much faster.  Swift enables developers to use generics and high-order functions and as a result, codes are clean and re-usable and thereby saves a lot of time.

6. Open Source


In 2015, Swift has been declared as an open-source, which changed the face of the language to a great extent.  After the declaration, Apple allowed swift to be used for various purposes. Since, Swift is an open-source, it’s always easy to upgrade the codes, track the bugs and create the email list. Apple also receives feedback from the community and has been making changes accordingly. Swift also supports Linux based platforms making the platform diverse. Hence, making Swift the preferred choice for iPhone application developers.

7. Better Safety


Thanks to its enhanced typing system and error handling capabilities, an error that happens in Swift programming is much less compared to that of Objective-c. It’s evident that safety was the prime concern in developing such a robust language.  Owing to the short feedback loops and the error tracking capability developers will be able to see the errors in their coding instantly. 

8. No Clogging of Memory


Swift is light! Thanks to its dynamic library support. Since static memory is absent in Swift, there won’t be an issue of memory clogging up. And also, dynamic libraries tend to have only one copy and thus, footprint can also be considerably reduced.

Not Just For iOS Apps


There is a widespread misconception that only iOS developers can use Swift to develop iOS applications. Swift was adopted by Linux and many other platforms and programs for development related activities. But the fact is that Swift is that it can be used to develop Android applications too.

Swift is relatively a new programming language. But the kind of momentum it has gained in this short span of time is unimaginable. iOS developers and those who wish to learn Swift language must understand one thing. Demand to outsource mobile app development in india using Swift will rise exponentially. Keep yourself prepared. For businesses,  Swift has opened new gates of opportunity since development time required is much less than it used to be.
