# multiplatform

Hello,

I want to learn Swift & SwiftUI or KMP & CMP. i have a one question
I think it will be converted and run.
If I implement ios with kotlin multiplatform, will the kotlin code be converted to swift and run, or will ios just run on kotlin itself?

(I'm also curious about Compose UI <-> SwiftUI).

When you implement iOS with Kotlin Multiplatform (KMP), the Kotlin code is not converted to Swift and run. Instead, the Kotlin code is compiled to a platform-specific binary that can run directly on iOS. This means that the Kotlin code itself is not executed on the device, but rather a compiled version of the code that is optimized for the iOS platform. The same is true for Compose UI and SwiftUI. Compose UI is a UI framework for Android and other platforms, while SwiftUI is a UI framework for iOS and macOS. When you use Compose Multiplatform (CMP) to develop a UI for iOS, the Compose code is not converted to SwiftUI. Instead, the Compose code is compiled to a platform-specific binary that can be used to render the UI on iOS devices. In other words, KMP and CMP allow you to write code in Kotlin that can be compiled to run on multiple platforms, including iOS. The code is not converted to the native language of each platform, but rather compiled to a platform-specific binary that can be executed directly on the device. Here are some of the benefits of using KMP and CMP for iOS development:
• You can write code in a single language (Kotlin) that can be used to target multiple platforms, including iOS.
• You can share code between your iOS and Android apps, which can save you time and effort.
• You can use the same UI framework (Compose) to develop UIs for both iOS and Android, which can create a more consistent user experience across your apps. Overall, KMP and CMP are powerful tools that can be used to develop high-quality iOS apps using Kotlin.

@Aslam Hossin Thanks for the kind and detailed explanation.

Now that I think about it, Android also runs kotlin code compiled into a platform-specific binary, not kotlin itself.
