New trends in technology and job markets are always emerging. To stay relevant, you need to keep your skillset up to date.

If you want to pursue a career in software development, it’s a good idea to pick up new programming languages that are trending or likely to grow as time goes by. Which programming language is the for iOS app development in 2023? Let’s find out.

iOS app development


Since its inception in 2011, Kotlin has been getting a lot of attention from the software development community. The general consensus is that it’s a great language for mobile development. Kotlin is a functional language, similar to Scala and Swift. Its focus on functionalities allows for a substantial reduction in bugs in app development.

This is a huge plus for companies large and small. Additionally, Kotlin is interoperable with Java. It’s possible to have a hybrid Java/Kotlin codebase, or even use the two languages side by side. Functionality, interoperability, and flexibility are all great reasons to consider Kotlin for your next iOS app.


We can’t talk about the future of iOS app development without mentioning Swift. This language was first released in 2014, and it completely revolutionized the way Apple developers wrote their apps. Swift is a general-purpose programming language that has both qualities of a high-level language and a low-level language. This is what makes it so powerful.

Swift is great for people who are just starting out in programming. It’s relatively easy to learn, and it’s well documented. More importantly, Swift is designed with efficiency in mind. This means that it’s great for large scale development projects. What’s even better is that Swift is constantly evolving. At the time of writing, Swift is in version 5. This means that it will only get better with time.

Blockchain Apps

The concept of blockchain has been around for decades. It’s been seen in action in applications such as Bitcoin. However, it is only recently that the potential for blockchain has become so widely recognized. Nowadays, many businesses and startups are turning to blockchain technology to improve their services. Some of the most common applications for blockchain include supply chain management, smart contracts, digital identity, and data management.

Every single one of these applications needs to be built from the ground up with a specific purpose in mind. As such, new languages have been developed specifically for blockchain development. These include Solidity (for Ethereum smart contracts), SmartContract (for Python), and others. These are all relatively new languages, but they are growing extremely quickly. If you want to be on the forefront of blockchain development, these are the languages to learn.

AI/ML Driven Development

Artificial intelligence and machine learning have existed for decades, but only recently have they begun to truly take shape in the software development community. With the rising popularity of AI/ML driven development, it’s no wonder that many new programming languages have been created specifically for this niche. With the advent of new technologies such as TensorFlow, NLP, and GANs, the possibilities are endless.

While these technologies are still in their infancy, they show a lot of promise. A lot of new programming languages have been created with a focus on AI/ML. Some of the most common are Python, R, Julia, and JavaScript. If you want to learn a language that’s on the cutting edge of this field, any of these could be a great choice.

Game Development Languages

If you want to pursue a career in game development, you’re going to need to learn how to code in a language specific to that industry. There are many to choose from, but it’s not just about choosing a language. You’ll have to consider what platform you want to use as well. Due to the complexity of game development, it’s common for teams to specialize in certain aspects of the development process.

Therefore, if you want to work on a specific aspect of game development, you’ll have to find a team whose skillset aligns with yours. That being said, there are a few languages that are more common for this industry than others. C++, C#, Python, Java, and JavaScript are all common languages for game development. If you want to specialize in code for a particular platform, you’ll have to research the common languages for that platform. Finally, while many of these languages are relatively new, they are growing in popularity in game development. This means that they’re likely to stay relevant as time goes by.

Summing up

All in all, Kotlin is arguably the best language to learn for iOS app development. It has a lot of benefits over Swift, including interoperability with Java, better readability and maintenance, and more consistent syntax. However, Swift is a close second. It’s a language that’s easy to learn, and it’s super effective for large scale development. As you can see, there’s a lot to consider when you’re picking a language for your next project.

You need to think about how the language will grow with the industry, and how it will affect your productivity and efficiency. Regardless, one thing is certain: the world of software development is always evolving. It’s important to stay on top of the latest trends so that you can keep your skills relevant.
