The Best Programming Language For App Development In 2022

If you want to work as a mobile app developer in 2022 but aren’t sure which programming language to choose, you’ve come to the right place.

As the demand for mobile apps grows every passing day, so is the demand for App developers. People with skills in Android and iOS app development are in great demand as both big and small companies are hiring app developers to build their mobile apps.

While there are many programming languages available, not all of them are suitable for app development. That is why it is critical to understand the options and select the best programming language that will enable you to not only create apps for Android and iOS but also to become a more all-round app developer.

For aspiring app developers, there are a lot of choices available to start with app development like you can use Java and Kotlin to start with Android development, or you can use Swift to make iOS apps for both iPhone and iPad, or you can use a mainstream language like JavaScript and React Native to create cross-platform apps for both Android and iOS.

Firstly Let’s know the different types of mobile apps

The Different Types of Mobile Apps

Native, cross-platform, and progressive applications are the three basic categories of mobile apps. You’ll be able to pick your ideal language for app development if you can narrow down what kind of app you want to construct.

Native mobile apps

What are native apps? A native app is an app for a certain mobile device (smartphone, tablet, etc).

Native apps for Android, iOS, and Windows are written in a platform-specific programming language. They are then downloaded from an app shop, such as Google Play or Apple’s App Store, and installed on a user’s mobile device.

Pros of native mobile app development:

  • Since they are designed specifically for one platform, native apps are often faster
  • They often deliver great user experiences, because they are tailor-made for a specific platform

Cons of native app development:

  • The cost and time to build can be higher, because there often needs to be separate versions of the same applications for various platforms (Android vs iOS). You can’t transfer the code from one operating system to another, because it’s written in a completely different language

Best use cases for learning native mobile app languages:

  • Native apps, which offer great performance, may be the way to go if you have a little more money and time. If you want your app to work on both Android and iOS, you’ll need to create two unique codebases.
  • Best for enterprise-level apps, especially if you just want to launch on one platform
  • People who do native mobile app development normally specialize in either Android or iOS, not both

Cross-platform mobile apps

A cross-platform mobile app is one that has one single codebase that works on both Android and iOS.

Pros of cross-platform apps:

  • Cheaper and faster to create
  • Works on all operating systems with one single codebase; more reusable code
  • Shorter time to market

Cons of cross-platform apps:

  • Can lack in performance/speed when compared with native apps

Best use cases for learning cross-platform app languages:

  • Cross-platform apps may be the ideal alternative if you’re on a budget and short on time. They’re excellent for smaller, simpler programs or hobbies. If you wish to launch across many platforms, this is also an excellent option.

Progressive web apps

Perhaps the most unconventional type of app, Progressive Web Apps (PWAs) are written to run inside a web browser instead of a mobile device. PWAs use HTMLCSS, and JavaScript, while other mobile apps use specific mobile development languages. They are like a hybrid of regular websites and mobile apps.

Pros:

  • Don’t need to know any specific mobile app languages; you can just use HTML/CSS and JavaScript
  • Affordable to create

Cons:

  • Can’t put on app stores
  • Fewer functionalities than true mobile apps
  • Limited features offline

Best use case:

  • PWAs are a good option if you need a very basic app (e.g. for personal use) and don’t care about selling it through an app store.

Best Native App Coding Languages

Want to build native applications? Let’s look at the best programming languages for iOS vs Android development.

Best iOS App Languages

What’s the best coding language for apps on iOS? For iOS native app development, focus on Objective-C or Swift.

1. SWIFT

Swift is a programming language for iOS, iPadOS, macOS, tvOS, and watchOS that is both powerful and easy.

Swift

Creator/origin: Introduced by Apple in 2014 as a replacement for Objective-C (which had been around since the 1980s)

Popularity/adoption levels:

  • Swift is used by 5.1 percent of developers polled by Stack Overflow (caveat: not all survey respondents are mobile developers, but you can compare it to the adoption levels of Objective-C above which is 2.8 percent )
  • 53% of “Swift and Objective-C developers” are Swift-only

Pros:

  • The iOS language of the future
  • Relatively easy to learn, especially when compared with Objective-C; simplified syntax & grammar

Cons:

  • Still a young language, which means there are frequent updates and changes that could change your codebase
  • Can’t be used for legacy projects running on older versions of the operating system

Types of companies that use it: Newer companies, smaller companies, startups, etc.

Career prospects:

  • Over 7,000 jobs on Indeed with “Swift” and “iOS” in the job description
  • Swift developer salary: $102,850 per year, on average

💻 Courses: 

2. OBJECTIVE-C

Objective-C is a general-purpose, object-oriented programming language used to develop apps for iOS.

Creator/origin: Developed by Brad Cox and Tom Love in the early 1980s

Popularity/adoption levels: 

  • Objective-C was the standard programming language supported by Apple for developing macOS until Swift came along in 2014. However, Objective-C is still being used today. It will likely not become obsolete any time soon because, thanks to its nearly 40 years of existence, it has a large code base. 

2.8% of developers in a Stack Overflow survey report using Objective-C

Pros:

  • Reliable and has been used and tested by many developers.
  • Lots of learning materials out there
  • Compatible with C++
  • Decent job prospects as there are tons of legacy apps out there that need to be maintained

Cons:

  • Big learning curve; Need to understand a bit of C, so you need to essentially learn two languages. Plus, you’ll need to know object-oriented programming.
  • Not the mobile app language of the future; newer apps aren’t typically being built with objective-C

Types of companies that use it: Bigger companies that have been around for a while and are using Objective-C in legacy codebases

Career prospects:

  • Over 5,000 jobs on Indeed that list “Objective-C” in the job description 

The average salary for an Objective-C developer is $123,422 per year. Because it’s more difficult to learn and more developers are focusing on Swift, salaries for Objective-C talents are greater because they’re harder to come by.

How to Choose Your Best Coding Language for Apps

Your best language for app development depends on your goals. The first step is deciding if you want to focus on iOS, Android, or cross-platform apps.

To narrow down what kind of apps to build and the best language to develop mobile apps on your platform of choice, consider these five factors.

1. Market demand, popularity, and trends

According to Statcounter, the global market share of Android is about 69.74%, while iOS market share is 29.49% (as of January 2022). However, if we look at only the US map, iOS is leading the race with 59.87%, while Android has 39.81%

StatCounter - mobile operating system market share

That means if you’re in the US, iOS has more market share. If you’re outside the US, Android might be more popular.

Look at what is older/possibly being phased out (i.e., Objective-C and Java) vs. what is up and coming and represents the “future” of mobile app languages when choosing on the ideal programming language for mobile apps (i.e., Swift, Kotlin).

2. Speed, development time, and functionality 

Other variables like as speed, development time, and functionality might help you narrow it down if you want to build your own apps. Depending on what you’re producing, Swift may be faster than Objective-C while developing an app. For you, that could be a deal-breaker.

If functionality is your #1 consideration, you might want to learn native app development languages instead of cross-platform, even if it takes longer.

3. Previous experience / your preference

Do you already have programming experience in another language? On that foundation, you might be able to construct. If you already know C#, for example, Xamarin could be a natural choice because it is designed using C#. Alternatively, if you’ve tried Java and disliked it, you can rule it out as an app coding language.

4. Support and documentation available

When deciding which language to learn for app development, support, community, and documentation can all play a role. If you want to be a part of a community with a lot of documentation, Stack Overflow answers, and so on, you might want to go with a more popular mobile language (like Swift, Java, or React Native) so you can get the help and community you need.

5. Your career goals

If you already have an end goal or dream job in mind, that can instantly narrow down the best language for app development to get you there.

If you’ve answered all these questions and still haven’t narrowed it down to one best language to develop mobile apps, that’s fine! I’d suggest taking a beginner course on each language you’re considering, to see what you resonate with.

There’s More Than One Best Language for App Development

Ultimately, there are pros and cons to all the best programming languages for mobile apps. Different app languages will be best for different situations! 

The key selling point of cross-platform mobile languages like React Native, Flutter, and Xamarin is “write once, use everywhere” (i.e., having a single code base for iOS, Android, and other platforms).

However, cross-platform languages don’t have all the features you get with native app languages and are often “heavier,” meaning they take up more space than native apps, which can cause them to be slower to update, download, etc.

After you’ve selected whether you want to go native or cross-platform, you’ll need to choose a language. This is dependent on your objectives (e.g., creating your own app, landing a job at a large tech firm) and your areas of interest.

While it may appear difficult at first, considering your future in technology, your past experiences, and even looking at what your dream company is presently utilizing, among other things, will help you narrow down the best app development language for you!
