and we need a way to make them work. There are several ways to use Swift dependencies in Kotlin Multiplatform. If we’re lucky and the library has a CocoaPods dependency, some libraries expose Objective-C headers and can be used directly in Kotlin by including...
Example: Kotlin or & and function fun main(args: Array<String>) { val a = true val b = false var result: Boolean result = a or b // a.or(b) println("result = $result") result = a and b // a.and(b) println("result = $result") } When you run the program, the output...
For example, Kotlin has sealed classes, data classes, abstract classes, and enum classes that let you dive deeper and explore that class’s options. In this guide, we will learn the concept of sealed classes and how to use them in Kotlin. Contents What are sealed classes? A glance at ...
