kmm-production-sample VS Retrofit

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/

from this point on, I will assume, you have a basic understanding of Retrofit. To get the most out of this tutorial I would actually suggest you have a retrofit client already implemented in your application.

Now you might think that in order to make the request we are going to use Retrofit but in reality we are going to be sending out an implicit intent like so:

This particular blog post will be us building on the information from the previous blog post and using the authorization code from the GitHub OAuth API in combination with Retrofit. To finally get a access token, which allows us to make requests to the API on a behalf of a user.

Hey HN!

If you're a fan of Swift you may have noticed that with WWDC 2023 came the (beta) release of macros. They're super powerful and expressive!

I've been wishing Swift had a [Retrofit](https://square.github.io/retrofit/) style API definition library for years, and with macros it seemed like this was now possible.

I'd like to show you all Papyrus, a library that turns your APIs into type-safe Swift protocols.

Would love to get your feedback.

When it comes to consuming APIs I can definitely recommend Retrofit. Hopefully that's enough to get you started on where to look!

For Android you should use a more mobile friendly framework like Retrofit or if you use Kotlin you can use the multi-platform Ktor library with it's client module

for example https://square.github.io/retrofit/ have mentioned it in at the bottom. Similarly there maybe other rules for other dependencies. Usually I search the missing classes error in google and find some proguard rule for it.

Retrofit in combination with OkHttp for fetching data from server (which hopefully already exists)

The first get request is to retrieve a list of objects and the second one is to get a single one. You can read more about RetroFit here.

So I've been playing around with search.maven.org and perhaps I'm not quite understanding it. For example, if I look for Retrofit I'm not seeing anything that resembles retrofit above https://central.sonatype.dev/search?q=Retrofit.
