kmm-production-sample VS SpotiFlyer

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/

There are also other ones like Powertube, Seal, Tubemate, SpotiFlyer(for music). Use whichever one you like.

Oh, the Spotiflyer isn't working; issue discussion

Alternative way would be : download Spotify pc app and then going to liked songs and selecting it all and then it will show icon to create playlist go ahead and create. Then you can use Spotiflyer copy the playlist link and then paste it spotiflyer and hit download entire playlist

> considering I don't want "missing" songs ever.

If that's your criteria, you'll probably never be satisfied with a licensed streaming service. Maybe YouTube Music?

I use Spotify alongside an offline library of backed up, obscure songs that aren't on there or have been removed. It's not a perfect system (and I'm regularly enticed to go fully-local), but I'm fairly happy with it. Dump all your liked songs into a public playlist, and Spotiflyer[0] will attempt to back up those tracks. Hopefully that helps!
