Hi All, Has anyone explored creating custom iOS and android SDKs using KMM? I would like to know some good practices and challenges using KMM for SDK development.

[Matheus Matos]

Hello, yes. I'm developing an iOS/Android app using a custom and shared SDK to handle network requests and some storage (preferences, cache, database). It works fine!

[Deepesh Vasthimal]

Thanks, @Matheus Matos, I was looking for answers from the SDK development point of view and not the App itself. If anyone has shipped a production iOS and Android SDKs using KMM and not App. Any references to existing KMM SDKs in production will really help.

Do you target Kotlin or Swift consumers?

[Deepesh Vasthimal]

We aim to target both consumers who want to write native Apps.
Our Consumers: Looking for native SDKs to build Apps.
Us: We create these public-facing custom SDKs which support both iOS and Android for native SDK app developers

I am aiming to use this option from the android studio to create Kotlin Multiplatform library.

Yes, it is entirely possible to implement an SDK with KMM. You would need to provide specific platform implementations. In my case, I have a SDK.initialize() method that takes Context as a parameter in Android, but it doesn't exist in iOS. However, in general, you can reuse the majority of the code.

@Matheus Matos You can use Splitties App Context if you just need access to the application context on Android.

[Deepesh Vasthimal]

@louiscad What is Splitties App Context ? , I am a bit new to KMM as you can see from my questions 🙂

[Deepesh Vasthimal]

Splitties is a collection of small Kotlin multiplatform libraries (with Android as first target).

[louiscad]

@Deepesh Vasthimal First result on Google for "Splitties App Context" : https://splitties.louiscad.com/modules/appctx/

[Deepesh Vasthimal]

Splitties mentions Android as the first target. What about iOS support then ?. Is there any example of KMM SDK which is adopted on both iOS and Android platforms?

[louiscad]

Splitties App Context is only a small part of Splitties, and it's for what the documentation I linked says it is. You don't have that specific Context problem on iOS, so it's irrelevant.

[louiscad]

Splitties itself has some modules that target iOS as well, but I don't think it's relevant to your specific use case.

[Deepesh Vasthimal]

@louiscad Coming back to this, Are these KMM libraries not supported for iOS?

I am looking to create something similar that can work on iOS and Android, consumed by native iOS and Android App developers.

[louiscad]

KMM≠KMP

[Deepesh Vasthimal]

@louiscad Are the above not KMM based libraries ?

[louiscad]

Take some time to uncover the acronyms, and how they are related to each other, everything will make more sense to you once you'll get that
