I’m so happy I’ll be able to use kotlin for iOS as well 🎉🎉, I hope you guys release video about kmm once a week, that would be awesome

[dipakbari]

I wish to have a Kotlin Multiplatform development playlist/series/channel.
Thanks for sharing this video. 🙏

[malcolmcollinable]

Nice series!

Please cover:
- adding KMM to existing iOS and android projects
- gRPC clients

[jshoes]

wow it prints a line of text, amazing! give this woman a cigar!

[dmqinbl]

Where do I start if I'm and beginner/intermediate because I see the code and I can't understand what's going on, I get that is necessary to understand some gradle configurations, so where do I start to be able to understand this topic, javaScript?

[gheisha]

How can I set up a new KMM project on windows without KMM plugin? I use Windows and I know KMM plugin is to be used only on macOS but I need to set up an kotlin multiplatform project just for Android for the moment

[alexanderknauf]

Really nice introduction. We are really exited to add KMM to our long-lived Android/iOS apps. Plz keep this series on

[mrt]

I can't wait for the next videos....

[gofarputra]

So, are we able to code app for ios from android studio?

[darkrap]

Is it will work with Hilt and RxJava too?

[bckside]

It doesn't make sense for me to test the common code from the 2 platforms.
You effectively test if KMM works correctly but that's not your job, it's theirs.
Common/shared code should have a common/shared test.
Platform specific code will have platform specific test.

[kartikagarwal]

Need tutorial on how to migrate current KOTLIN Project which are in production to KMM

[khalidmohammed]

When the next episode will be available??

[javalnanda]

For those facing issues running the iOS app after adding datetime library on M1 macs, updating the library to 0.3.2 fixed the issue for me.

[harmindersingh]

can I use KMM on windows for creating both Android and IOS app ...?
is KMM also we use same code base like in react native and flutetr ..?

[yuruar]

Отличное видео, как всегда понятно и полезно)

[kfldp]

I have something missing right away. In Create new project, I have no KMM Application option.

[samuel.bailey]

Anybody else have a problem with the iOS emulator?

[serhiipanchenko]

Why don't you develop a wizard for Intellij allowing us to create a multiplatform project with any tagrets we need? For example, I need a project with ios, android and jvm backend targets, so I can check all these checkboxes and create a project including these targets.

A tutorial on KMP for android, javascript and server would be helpful.
