Why Migrate to Swift From Objective C, explains Nikhil Juneja, Chief Technical Officer at Root Info Solutions. Contact our Swift iPhone App Developers today.


From smartphone and smartwatch to smart TV and smarthome – Apple is, undeniably, the pioneer in making 'smart' tangible and likeable. Ever thought how it makes it happen? Nikhil Juneja, Chief Technical Officer, Root Info Solutions, an iPhone app development company, attributes it to the migration to Swift from Objective C. Learn the whys and wherefores.

A software application is an interface between the human and the device. And with the changing digital consumption behavior of the users and their rising expectations, mobile application developers need to build better applications equipped with artificial intelligence having better response to stimuli. The conjuring effect that we witness on or through these devices is nothing but the ripples caused by its programming language. With the introduction of Swift, the latest mobile programming language for developing apps for iOS, OS X, watchOS, tvOS and Linux-based machines, Apple reiterates its intention to make these products work much smarter. The new bunch of features and capabilities offered with Swift are also understood to empower every iPhone apps development company.

Let's see the advantages of migrating to Swift from Objective-C, the previous language from the point of view of an iPhone app developer.

1. Swift is easier to read and apply

In Objective C, new keywords were used using the @ symbol to differentiate from the parent C language, but Swift skips the @ symbols in front of every Objective-C type or object-related keywords. Swift doesn't ask for legacy conventions like semicolons to end lines or parentheses to surround conditional expressions inside if/else statements. Developers get freedom from using multiple symbols [[[ ]]] to seclude calls. Swift uses simple and standard commas to separate entities. Moreover, Swift resembles more to the modern English language in terms of syntax and grammar and allows programmers from different fields like JavaScript, Java, Python, C#, and C++ to develop programs in a quick and easy manner.

2. Swift is easier to maintain


Similar to C, in Objective-C, programmers have to maintain two code files while updating or upgrading a mobile app to address any issue which makes programming complicated. Swift dropped the two-file concept. Xcode and the LLVM compiler, the fundamental components of Swift, can identify dependencies and perform incremental builds automatically. It saves time as programmers don't need to segregate the table of contents (header file) from the body (implementation file) time and again. Swift merges the Objective-C header (.h) and implementation files (.m) into a single code file (.swift) to help Swift developers work effortlessly.

3. Swift is safer

Swift can precisely locate any bug in the application program, and help programmers to overcome any technical issues outright. It triggers a runtime crash when a nil variable is used. This is not the case with Objective C. Here,
the nil variable stays immune in terms of response. In addition, programmers are required to document the behavior of the pointer variable using comments and tedious method-naming convention, whereas, in Swift, optional types and value types make the reporting task easier.


4. Swift automates memory management

Swift is endowed with automated and high-performance memory management tool called Automatic Reference Counting (ARC), so iPhone app developers, while creating a digital object, don't have to stay concerned about memory. Though it was there in Objective-C, but was confined to Cocoa APIs and object-oriented code. Thus, a Swift iOS developer can work faster and deliver more in less time.

5. Swift requires less code

Whether it's working with repetitive statements or connecting strings, Swift makes all easier with its hi-tech programing capability. For instance, “+” operator can be used to link two strings. In Objective-C, combining strings required providing too many ambiguous and complicated steps often filled with bombastic language.

Swift also takes away the complexity of code statements as iPhone app developers don't have to mug up special string tokens(%s, %d, %@) and recall the usage of the comma-separated list of variables. Thanks to the efficient compiler that can automatically figure out types.

6. Swift is faster

Sacrificing the legacy C convention, Swift has improved its performance drastically observed Primate Labs which is recognized for its popular GeekBench performance tool. Based on Mandelbrot algorithm, Swift equalled the performance of C++ for compute-bound tasks in December 2014 test.

In February 2015, after the release of Xcode 6.3 Beta, the performance of Swift, based on GEMM algorithm, increased further by a factor of 1.4. The result was even more encouraging when evaluated against FFT (a memory-bound algorithm with random access of large arrays). Here a record 2.6-fold increment was noticed.

7. Swift welcomes open source projects

Unlike Objective-C, Swift extends formal support to namespaces. Here same code files can co-exist across multiple projects without leading to build failure. Thus, the book-keeping practice takes a backseat too, and programmers can focus better on doing next bigger things. In Swift, simple namespaces like Array, Dictionary, and String are used unlike NSArray, NSDictionary, and NSString in Objective-C. Being an iPhone app developer, you can observe that namespaces are in accordance with the target that a code file belongs to. This makes integration of open source projects, frameworks and libraries easier with Swift.


8. Swift supports dynamic libraries

Last but not the least, the inclusion of dynamic libraries in Swift gives Swift-based apps an edge over those developed in Objective-C, and also with other counterparts. Its current app can connect with the updated version of Swift language releasing in future. While submitting apps to the app store, developers need to submit apps along with libraries, and both should be digitally signed. Any changes to the libraries will reflect in the submitted app that will make future amendments easier.

Hope you found the Swift Vs Objective-C match fascinating enough to drive the iPhone development instint in you. Do share your inputs and experience regarding the same. We can collectively make the world of mobile apps development more fulfilling and interesting. If your quest was of finding the right Swift developer , don't look further.
