How can we handle api response in both platform in ios and android in kotlin mutlplatform?

Question

Hey I am new in the world of Kotlin Multiplatform mobile. I have experience in development of android field. I am trying to connect Android application and Ios application. I searched and see Ktor is the way to fetch data from server. In android we use Kotlin Sealed Classes for Handling API Responses example in your application and in ios side team use Understanding Swift closures and asynchronous request functions similar to these. I am little bit confused, How can I use this way in common module to use both platform because both platform have Interceptor and many more things. Do I need to write everything from scratch? or Is there any way we can use existing way. My both platforms application is huge project. I don't won't to replace the code. I want to start new api call throught KMM using Ktor. Any suggestion or project would be helpful for me. Thanks

If you want to use old Android Code into Kotlin-Multiplatofrm Project you need to do some steps

First Step : you should separate your code into business layer and presentation layer you can know about it by reading clean architecture Android

Second Step : we will put business layer into Shared Module then we will put presentation layer into ANDROID APP

Third Step : you should replace Retrofit Code with Ktor Code

Fourth Step : You should replace Room Code with SqlDlight Code

fifth Step : You Should Write your view in presentation layer with Compose not Xml

then application will be ready to use his business logic into ios

sixth Step : then you can write your swift code into IOS APP

you can look at this code this is not complete code but it will make it clear to you haw you can use my Kmm Repo at Github

note :

Presentation layer contain view , viewmodel and any Platform dependent tools like workmanger

business layer contain network and caching code like KTOR , SQLDELIGHT and any logic that may be shared between Android and Ios
