Sharing Business Logic
Reuse across iOS and Android.
Why Share Business Logic?
UI differs per platform, but rules like validation, pricing, and data flow are identical. Sharing them in commonMain removes duplication and bugs.
Shared Data Models
Define your domain models once in common code. With kotlinx.serialization they also serialize identically on both platforms.
import kotlinx.serialization.Serializable
@Serializable
data class Product(val id: Int, val name: String, val price: Double)All lessons in this course
