Selecting the best suitable programming language is the most critical decision that software engineers need to make in the early process. Less maintenance cost and time, app longevity, and the best possible user-experience are features that most of the startups require in their mobile app. There are hundreds of programming options available these days.
However, the following five languages happen to be some of the most recognized ones.
Simply put, it is a kind of primary programming language used in developing apps for Apple’s wide-range of products. In spite of other options, Swift is often considered hot favorite by developers. Launched in 2014 by Apple, the programming language currently manages to remain in the list of top ten. It is regarded as a simple programming language as it is streamlined and agile. Due to these features, it has managed to surpass the popularity of Objective–C. The language is set to thrive in 2019 and the next few years as well due to its ever-increasing usage in developing products for WatchOS, iPad, iPhone.
Swift is open source and operates on Linux. Some of the renowned apps built with Swift are The Weather Channel, CNN, Apple Store, Airbnb, WordPress, LinkedIn, Truecaller, Lyft, Twitter, VSCO Cam, etc. Swift’s speed is often compared with that of C++. Its syntax and language are considered simple.
Chris Lattner is the man behind this programming language that offers better readability and low maintenance cost as prominent features. He was assigned the task to develop the same by Apple. Developers probably prefer to upgrade applications from Objective–C to Swift to ensure that users who opt for Apple’s high-end products get the best possible experience.
Developed by software firm JetBrains and launched in 2011, Kotlin has earned its reputation as the primary programming language for developing Android mobile applications. The language’s versatility with the back-end, front-end development, interoperability, security features, lesser application crashes, readable compact code, and ability to run on JVM are considered as the factors behind its fame. Even after eight years from its launch, the language has managed to attract new developers and retain its position in the top ten.
Between 2017 and 2018, as much as 20 percent of the applications developed with Java migrated to Kotlin due to its features, and of course, due to Google’s extensive validation.
Popular brands like Pinterest, Evernote, Uber, Kickstarter, Basecamp 3, etc. use Kotlin in a variety of applications.
Before the launch of Swift, the primary programming language for iOS powered devices was Objective–C. Developers can use C, C++, dynamic typing, and dynamic run-time with Objective–C. Creating a mobile application using this language is considered easy by most of the developers.
No doubt, Apple has succeeded in replacing Objective–C with Swift for OS X, and iOS powered devices. However, developers still enjoy using Objective–C and implement it wherever possible as it is reliable, well tested, and can connect with private APIs easily.
Objective–C and Swift are used along with HTML 5, C++, and Java for developing mobile games. It is also used in writing software for the desktop PCs. Overall, engineers who work on Apple products at smartphone app development company need to know both, Objective–C as well as Swift.
Often referred to as a high-level, object-oriented programming language, Python has been around since 1991. It happens to be both, robust and straightforward. Due to the extraordinarily simple syntax, it is easy to learn.
Used for mobile app and web development, Python offers dynamic binding and dynamic typing option. The language is easy when it comes to translating code and reading. This helps in reducing the development cost and in keeping the maintenance cost lower.
As it is FLOSS (open source) software, it is included in UNIX, Linux distributions and is also pre-installed in some Windows-powered computers.
Instagram uses Python web framework-Django, IBM has Python SDK for Watson, and Netflix’s AI-powered search engine also uses Python. Even YouTube, Google search, and NYSE’s web transactions system includes Python. It is also preferred by engineers working on data science, server automation.
College students prefer to learn JS because it is considered a general purpose language that is used in apps as well as web browsers.
Besides the above five, application development company may also use some of the other popular languages like HTML/CSS, Java, PHP, Ruby, C++, Pearl, Rust (Mozilla), and Buildfire.js.
The mobile app development has earned a lot of prominence during the last five years due to the increase in smartphone penetration. Small and large enterprises are slowly shifting to mobile applications as their primary channel to sell products and services.
These days, mobile app developers have their in-house teams that are well versed in developing apps with various programming languages.
