# multiplatform

[nrobi]

We've just published one of our internal KMP playground projects, some of the key points being:
• A shared ViewModel layer
• Declarative UI (Compose & SwiftUI)
• Image upload
• Shared localization (with moko-resources, thanks to @alex009 & the IceRock team)
• multiple KMP modules
• Android & iOS targets (with macOS coming soon, desktop & web planned)

Big thanks to @John O'Reilly & the Touchlab team, since some of the setup is based on either PeopleInSpace, BikeShare or KaMPKit

You can find the repository here

[alex009]

good work!
do you try use moko-mvvm for share viewmodels?

[nrobi]

@alex009 it’s definitely on the roadmap, though we’ve been waiting for #65, since with compose we didn’t need a lot from the artifact

[nrobi]

and as I see this was released 3 days ago, so I’ll definitely give it a go in the coming days, thanks 😄

[alex009]

yes, now mvvm have many artifacts for many usecases 🙂 good luck and will be glad to receive feedback

[ludOS]

I'll go read but file upload piqued my interest? ktor? services? pendingintentservicecoroutineworkers?

[nrobi]

@ludOS we’re using a simple expect/actual for the files, because of the following reasons:
• For the KTor multipart we only needed a ByteArray representation of the file
• The actual typealias-es work really well with our unidirectional flow: we get back either `NSImage`/`UIImage` or a wrapped Uri on the platforms

[ludOS]

Link to files ? 😅

[nrobi]

./shared/util/File.kt -> Though I should probably correct myself that this has to be tweaked on the iOS side for a more general file handling, since the current implementation is for Image file picking

[ludOS]

Yes I saw the image picking ans was a little confused 🙂

[nrobi]

Sorry about that, will edit the post 🙂

[Jozef Matus]

Thank you for sharing this, Im working on similar project and the lack of materials makes it hard. 🙂

[ludOS]

Oh. Interrewsting. Any prep work done on the CI or from scratch? Any issue or something in the repo to put the work? 🙂
I collaborated on these workflows and would enjoy trying a hand at KMM:

#5 - we had a WIP gitlab-ci setup with two stages (common -> independent platform jobs), which was dropped when we moved to Github

[nrobi]

on iOS we were just running xcodebuild . Your contribution @ludOS is more than welcome, and I'm happy to share some gists if needed 😄

[Jozef Matus]

I also have experience with setting up CI/CD on iOS, Android and RN. I wonder if it would be possible to do it in fastlane, that would be nice. I will soon have to implement some solution in my job, so I might share it.

[nrobi]

Yes, it should be possible with fastlane, we’ve also gone down that path on our WIP branch. If I remember correctly there are some articles about it also

[ludOS]

I propose I will create an issue regarding GitHub Action setup. I'll contribute at least the prep work directly in the issue, with a linked PR.
I'll watch with interest (I have no idea what fastlane is for example 🙂 )

Here we go https://github.com/halcyonmobile/MultiplatformPlayground/issues/6
I'm about to go through an airports vortex but I'll definitely find time on the 🏝️

[Qracle]

Hi can anyone build the project? I’m seeing Exception is: org.gradle.api.GradleException: Please initialize at least one Kotlin target in 'common (:common)'. Im on Android Studio Arctic Fox | 2020.3.1 Canary 4 Build #AI-202.7319.50.2031.7049475, built on December 23, 2020

[nrobi]

@Qracle there is an open issue, should work with canary 2
