kmm-production-sample VS Flutter

Business logic is not only about backend. Apps usually have a lot of client-side logic that can be written once in KMM and used on both platforms. See [1] for a high level architecture diagram.

I'm an iOS dev and I've been using KMM on a couple of projects for more than a year now. It's really a powerfull technology which allows teams to move faster, but there are downsides, for example lack of native Swift interop, though there are opensource tools trying to solve this [2].

I'm an Android dev for 10+ years and I've decided to give a go with Kotlin Mobile Multiplatform to try iOS development as well. For that purpose I would need a Mac obviously, and Windows 11's flaws don't help either so I made my mind and I would like to pick a Mac as my next developer machine for the next 4-5 years.

I don't use iOS, but https://kotlinlang.org/lp/mobile/ claims that using Kotlin works on iOS too. You still will need a Mac though, but that's pretty much a given if you want to develop iOS apps.

Kotlin Multiplatform with Realm as a middle layer.

Kotlin Multiplatform. You write the UI fully native for each platform, but have all the business logic as shared code.

maybe people confused it with kotlin multiplatform mobile which indeed support ios but only the business logic. you have to write the ui in swiftui.

I think the most compeling use for Kotlin Native is mobile. I wonder if it's possible to write a Kotlin multi-platform library that can then be used from the JVM, JS, iOS and Android? What would such library look like from the other languages? This is something I am trying to find out right now, and Kotlin Multiplatform seems to be the only sane choice to do this (but I am not sure yet that it's actually good/possible right now). Any more information about this would be appreciated.

Kotlin isn't just JVM and Kotlin projects like this one for writing iOS+Android apps look quite promising: https://kotlinlang.org/lp/mobile/

Thanks - that link does not appear to be open access, anyways I don't think I've seen it. I'm familiar with Flutter at a high-level (Kevin Moore gave a great talk on it at Wasm I/O), and I think other than requiring users to work in Dart, it is probably one of the most powerful ways to do cross-platform UI today.

Worth noting that their original GPU backend was Skia, and now they are retooling around Flutter GPU (Impeller)[0], which is kind of designed similarly as an abstract rendering interface over platform-specific GPU APIs.

If you are considering Electron/React then I would suggest adding Flutter to your list of technologies to consider. It uses Dart (a language similar to C#) and has a lot going for it… relatively quick to get up to speed with, fantastic developer experience (e.g., hot reload, great IDE support, good development tools) and very strong cross-platform support: it generates native iOS, Android, MacOS, Windows and Linux executables. Check it out: https://flutter.dev/

You can find the React Native documentation here and Flutter Documentation here.

> There is actually a great issue thread on the Flutter GitHub that explains exactly why other solutions do not work correctly when compared to hooks [0]

Interesting. I assume you are referring to this comment in particular -> https://github.com/flutter/flutter/issues/51752#issuecomment... ?
