Kotlin vs Swift
Kotlin and Swift are two programming languages that have taken the developer community by storm. They became rapidly popular due to their modern approaches and robust functionalities. Given their simple syntax and relative versatility, both were quickly adopted. They are both modern languages that accelerate development while introducing novel approaches and features, which is what makes them appealing together.
But the truth is that the question of Kotlin vs Swift is actually more complicated and has much more fascinating answers. While Kotlin is used for Android application development, Swift is used for iOS application development, which appears to be one of their differences. In this article, you will explore several differences between them so that you can make the right choice while selecting a programming language.
How Are They Different?
When selecting software development services, you should take into account a few significant distinctions between Kotlin and Swift. Kotlin is a more modern language than Swift, and it is designed to be more concise and easier to maintain. It is also better suited for mobile applications, while Swift is better suited for larger-scale projects.
Also, Kotlin has better support for object-oriented programming, while Swift is better suited for functional programming. You can learn more about their differences, which will be explained below.

1. Regarding Development
As mentioned earlier, even though they have similarities in terms of development, there is an essential difference that Kotlin is used for Android and Swift is used for iOS. For developers stepping into the world of Android applications, its solid features and smooth integration with Android Studio make it the go-to partner. It is newer than Swift, and it offers more features, such as lambdas, which are more concise and more accessible to use.
Conversely, Swift seamlessly integrates with Apple’s suite of platforms, guaranteeing top performance. It is also more widely used, so it may be easier to find developers with Swift experience. Both languages boast efficient coding, ease of use, and a fantastic developer experience.
2. Structs
Structs in programming languages represent (or reference) values and assist developers in organising variables into a single “list” or name. Because structs do not support inheritance, changes can only be made to the selected variable of the items within a particular group. While Swift is one step ahead of Kotlin in this regard, it still lacks specific struct types, allowing developers to select any struct they require for their projects.
3. Memory Management
Although memory management in Kotlin and Swift is different, it can be understood by picking up a few new acronyms. Swift has superior memory management over Kotlin since it employs Automatic reference counting (ARC) instead of the Garbage Collection Approach (GCA). When compared to GCA, the ARC technique is widely praised for being more accurate and effective at managing memory.
ARC also helps developers avoid memory leaks and crashes, which are common with GCA. Additionally, ARC is faster than GCA, making it a better choice for applications that require extensive memory management.
4. Error Handling
When it comes to error handling, Kotlin provides a solid foundation where the errors are indicated with null. Its type system facilitates simpler error handling by helping to preempt null pointer exceptions. On the other hand, in Swift, errors are indicated by using nil. Some of its features, like type inference and generics, help reduce errors and make the code more robust.
5. Function Implementation
Although Kotlin and Swift use somewhat similar approaches to modern programming when implementing functions, there are some notable distinctions. While Swift does, Kotlin does not use the underscore (_) in the variable as a prefix. Moreover, Kotlin returns to the argument for prefixes by using the variable name plus the $ symbol. Instead, Swift uses brackets and forward slashes.
6. The Data Class
One of the main distinctions between Kotlin and Swift is the data class. In addition to storing data, data classes automatically power several utility and standard functionalities. For Android developers, Kotlin classes are available, while they are not available in Swift. Kotlin classes provide a lot of support for Android developers, and the data class is an important feature. Swift developers, on the other hand, have to rely on other means to store data and provide standard functionalities.
7. The Default Class
Another noteworthy distinction between Kotlin and Swift is the default data class, although Swift wins out this time. While adding or changing any part of the default feature code is not permitted in Kotlin, extensions are allowed in Swift to provide extra functionality. It means that Swift offers more possibilities for developers to customise their code. Additionally, its default class is more expressive than Kotlin’s, allowing for a more robust data model.
8. Enumerations or Enums
When writing code, enums serve as symbolic names for a predetermined set of values that are used to protect data. They are used to create sets of constants that operate with variables and properties, and they are treated as data types. Put differently, enums are a great way to speed up programming. However, since Kotin does not support the enum list, developers occasionally have to take the “long way around” in order to use those enum patterns. Yes, Swift has enums that let developers perform computation properties quickly.
9. Annotations
Programming languages have annotations that allow developers to add metadata to apps’ code. Swift does not support annotations; however, Kotlin provides various annotation types that make in-app development easier. It provides developers with a powerful tool to debug applications. It also offers the ability to add custom annotations, which can help developers create more precise and efficient code.
10. Overall Support and Community
When it comes to programming languages, having strong institutional support and a vibrant community are essential. Google has supported Kotlin since 2017, whereas Apple and IBM are the two most prominent tech companies behind Swift. So, they both have a thriving community that actively supports developers through various forums and discussions, creating a supportive ecosystem for developers.
So, you read some of the significant distinctions between Kotlin and Swift. You should understand that the specific requirements of each project and the intended platform should be the deciding factors when choosing between them. Both of these programming languages are very similar to one another and very different from one another. This comprehensive comparison of Swift vs Kotlin examines the distinctions between the two languages’ implications for developing app code, and you should choose accordingly.
