Let namesWithAges = įunctions are the essential building blocks of any codebase.

Val namesWithAges = mapOf('John Doe' to 34, 'Jane Doe' to 29) Var namesWithAges = HashMap(20) //define capacity While dictionaries and maps by default can expand, in both Kotlin and Swift, you can define their capacity for improved performance. Val days = listOf('Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun')Ī dictionary (Swift) or map (Kotlin) is a very useful data structure when it comes to storing distinct values. Var names = ArrayList() //creates a list of strings, initially with no elements Lists can have a variable number of elements and can grow in size after declaration. Val days = arrayOf('Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun')Īnother Kotlin collection type, lists are similar to Swift’s array type. Note that, while the array above is mutable, you were able to assign it to a immutable variable using the val keyword – more on this later. To change the value of an item in the array: In the following example we declare a mutable array in Kotlin with five elements, all set to a default value of zero: In Kotlin, arrays can be mutable, but are declared with a fixed size. In both Swift and Kotlin, arrays have a fixed type - i.e., an array could be a collection of strings, for example, but not a mixture of strings and integers. Arrays, linked lists, dictionaries or maps, classes and interfaces are all examples of data structures. They are used to organize, store, and manipulate data. Data Structuresĭata structures are an important part of any language. So, as you can see above, the basic difference between declaring immutable properties in Kotlin and Swift are the val and let keywords.

Let quote = 'If you don't work smart, you will probably be replaced by an AI.' Val quote = 'If you don't work smart, you will probably be replaced by an AI.' To declare a property with type inference: var firstName = 'Ray' To declare a property with type inference: var firstName = 'Ray' Swift – Mutable Propertiesĭeclaring an integer in Swift: var age: Int = 15 Kotlin - Mutable Propertiesĭeclaring an integer in Kotlin: var age: Int = 15 Mutable properties can be changed or re-assigned but immutable properties can’t change. In both languages, there is a concept of mutability and immutability.

If you’d like to try out any of the following code snippets below for yourself, you can do so using a web playground for Kotlin or an Xcode playground for Swift. Swift and Kotlin are incredibly similar to one another. Understanding Similarities Between Swift and Kotlin This tutorial assumes you have a basic understanding of either Swift or Kotlin. While there is no hands-on tutorial, reviewing these language elements will provide you a great overview that will expand your knowledge of both of these languages. In this article, you will take a tour of Swift and Kotlin and how they compare.

Kotlin rolled out with Android Studio 3.0 in October 2017.

Google announced official support for Kotlin as a development language for Android in 2017. Kotlin runs on the JVM and is designed to interoperate seamlessly with Java, and is meant as a replacement for Java. Initially, Kotlin was developed by a group of developers from Saint Petersburg, Russia, working at the company JetBrains.

Swift can be mixed with Objective-C in projects, but is meant to replace Objective-C. Apple open sourced Swift on December 3, 2015. Swift has been a part of Xcode since version 6 was released. It works on top of the LLVM, an open source collection of compilers and toolchains. Swift first appeared in June 2, 2014, and was developed by Apple to work with the Cocoa Touch framework.

Both languages rapidly gained adoption due to their easy syntax, simple way of writing and the modern techniques and features they bring to the table. Swift and Kotlin have taken the developer community by storm, helping to increase the number of developers for both platforms.
