The rollercoaster of releasing an Android, iOS, and macOS app with Kotlin Multiplatform | KotlinConf

With the rise of Kotlin Multiplatform, the possibility of expanding to multiple platforms has increased, especially for Android Developers. It's easier than before to build for other platforms.

But how to release your app to multiple platforms?

In this talk, I will share all the things I've learned around distributing FeedFlow, an Android, iOS, and macOS app built with Kotlin Multiplatform, coming from an Android development background.

We will cover the deployment of the binary, automating everything with CI, crash reporting, logging, internationalization, and all you need to know to successfully distribute your KMP app.
