Are you tired of dealing with complex class hierarchies in your Kotlin Multiplatform projects? Do you want to explore alternative source sets that can simplify your codebase and make it more maintainable? Look no further! In this article, we’ll take a deep dive into the world of Kotlin Multiplatform and show you how to replace class with alternative sourceSet.
What is Kotlin Multiplatform?
Kotlin Multiplatform is a programming language framework that allows you to share code between multiple platforms, including Android, iOS, and desktop applications. It’s a powerful tool that enables developers to write code once and deploy it across multiple platforms, reducing development time and increasing code reuse.
The Problem with Classes
One of the biggest challenges in Kotlin Multiplatform is dealing with complex class hierarchies. Classes can become bloated and difficult to maintain, especially when working with multiple platforms. This is where alternative source sets come in – they provide a way to separate concerns and simplify your codebase.
What is an Alternative SourceSet?
An alternative source set is a way to organize your code into separate modules or sources that can be used across multiple platforms. Instead of using a single class to define your business logic, you can create separate source sets for each platform or feature. This approach makes it easier to manage dependencies, reduce coupling, and improve code readability.
Advantages of Alternative SourceSets
- Improved Code Organization: Alternative source sets allow you to separate concerns and organize your code into logical modules, making it easier to understand and maintain.
- Reduced Coupling: By separating dependencies into separate source sets, you can reduce coupling between modules and make it easier to modify or replace individual components.
- Increased Flexibility: Alternative source sets provide more flexibility when working with multiple platforms, allowing you to tailor your code to specific platform requirements.
How to Replace Class with Alternative SourceSet in Kotlin Multiplatform
Now that we’ve covered the benefits of alternative source sets, let’s dive into the implementation details. Here’s a step-by-step guide on how to replace class with alternative sourceSet in Kotlin Multiplatform:
Step 1: Create a New SourceSet
In your Kotlin Multiplatform project, create a new source set by adding a new folder or module to your project structure. For example, you can create a new folder called “domain” and add a new source set called “DomainSourceSet”.
project domain DomainSourceSet ...
Step 2: Move Business Logic to the New SourceSet
Move your business logic code from the original class to the new source set. For example, if you had a class called “UserManager” that managed user data, you can move the logic to a new file called “UserManager.kt” in the “DomainSourceSet” folder.
DomainSourceSet UserManager.kt
fun getUserDetails(userId: String): User {
// business logic implementation
}
Step 3: Define the SourceSet in the build.gradle File
In your build.gradle file, define the new source set by adding a new source set configuration. For example:
sourceSets {
main {
// ...
}
domain {
kotlin.srcDir 'domain/DomainSourceSet'
}
}
Step 4: Configure the SourceSet Dependencies
Configure the dependencies for the new source set by adding the necessary dependencies to the build.gradle file. For example:
dependencies {
implementation 'org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.5.31'
implementation 'com.squareup.okhttp3:okhttp:4.9.0'
}
Step 5: Use the Alternative SourceSet in Your Code
Finally, use the alternative source set in your code by importing the necessary modules and classes. For example:
import domain.UserManager
class MyViewModel {
private val userManager = UserManager()
fun getUserDetails(userId: String): User {
return userManager.getUserDetails(userId)
}
}
Best Practices for Using Alternative SourceSets
When using alternative source sets in Kotlin Multiplatform, it’s essential to follow best practices to ensure maintainability and scalability. Here are some tips to keep in mind:
- Keep source sets small and focused on specific domains or features.
- Use clear and descriptive names for source sets and modules.
- Avoid complex dependencies between source sets.
- Use interfaces and abstractions to define contracts between source sets.
Conclusion
In this article, we’ve explored the benefits of using alternative source sets in Kotlin Multiplatform and provided a step-by-step guide on how to replace class with alternative sourceSet. By following these best practices and implementing alternative source sets in your projects, you can simplify your codebase, reduce coupling, and improve maintainability.

Frequently Asked Question
Get ready to dive into the world of Kotlin Multiplatform and discover the secrets of replacing classes with alternative sourceSets!
Q1: Why would I want to replace a class with an alternative sourceSet in Kotlin Multiplatform?
You might want to replace a class with an alternative sourceSet when you need to use a different implementation for a specific platform or when you want to provide a custom implementation for a particular feature. This allows you to decouple your business logic from the platform-specific code, making your project more modular and easier to maintain.
Q2: How do I declare an alternative sourceSet in Kotlin Multiplatform?
To declare an alternative sourceSet, you need to create a new folder in your project’s root directory with a name that follows the `src/{sourceSetName}` convention. For example, if you want to create an alternative sourceSet for iOS, you would create a folder named `src/iosMain`. Then, you can add your alternative implementations in this folder.
Q3: How do I replace a class with an alternative implementation in Kotlin Multiplatform?
To replace a class with an alternative implementation, you need to use the `actual` keyword in your alternative sourceSet. For example, if you have a class named `Platform` in your common sourceSet, you can create an alternative implementation in your iOS sourceSet by declaring a class with the same name and using the `actual` keyword, like this: `actual class Platform { … }`.
Q4: Can I use multiple alternative sourceSets in Kotlin Multiplatform?
Yes, you can use multiple alternative sourceSets in Kotlin Multiplatform. This allows you to provide custom implementations for different platforms or features. For example, you can have one alternative sourceSet for iOS and another for Android, each with its own implementation of the `Platform` class.
Q5: What are some best practices for using alternative sourceSets in Kotlin Multiplatform?
Some best practices for using alternative sourceSets in Kotlin Multiplatform include keeping the common sourceSet as lean as possible, using the `actual` keyword consistently, and organizing your alternative sourceSets in a logical and consistent manner. This will help you keep your project maintainable and easy to understand.
