Hello, I’m trying to create multiplatform project ...

[AG]

Hello, I’m trying to create multiplatform project using new kmm plugin, but I have a problem with ios when defining store Use of unresolved identifier 'DefaultStoreFactory'

let store = NotesStoreFactory(DefaultStoreFactory())

here is my build.gradle.kts file from shared module

val commonMain by getting {
    dependencies {
        api("com.arkivanov.mvikotlin:mvikotlin:2.0.0-rc3")
        api("com.arkivanov.mvikotlin:mvikotlin-main:2.0.0-rc3")
        api("com.arkivanov.mvikotlin:rx:2.0.0-rc3")
       //other deps
    }
}

Can someone help me to figure out what was the problem ?

[Arkadii Ivanov]

Hello. Is it compile time or runtime error?

[AG]

compile time

[Arkadii Ivanov]

Could you please post a full gradle config?

[AG]

sure

Could you please try exporting dependencies? https://github.com/arkivanov/MVIKotlin/blob/3c17b1a4841006d40f4cd1fede681e42e70055a1/sample/todo-darwin-umbrella/build.gradle.kts#L33

[AG]

I’ll try it now

[AG]

I’ve tried like this but it’s not worked, defaultstorefactory again doesn’t resolved by xcode

ios {
    binaries {
        framework {
            baseName = "shared"
            export("com.arkivanov.mvikotlin:mvikotlin:2.0.0-rc3")
            export("com.arkivanov.mvikotlin:mvikotlin-main:2.0.0-rc3")
            export("com.arkivanov.mvikotlin:rx:2.0.0-rc3")
        }
    }
}

maybe I did something wrong here?

[Arkadii Ivanov]

I think I will need a reproducer project. You can strip out any code you don't want to disclose. Or if it is an open source project, just a link would be good

[AG]

np, that’s my first test project with kmm, so I’ll push it to github and send you link

[Arkadii Ivanov]

This would be awesome! I could check it later tonight

[AG]

thank you very much 🙌

I have submitted a PR fixing the issue: https://github.com/arthur-ghazaryan/test-kmm-app/pull/1

[Arkadii Ivanov]

The point is to properly export external dependencies. A suffix with the current target should be added.

[AG]

Thank you very much 👍

[lehakorshun]

Hi @Arkadii Ivanov thx for the solution. Do you why is this happening or where can I read about it?

[Arkadii Ivanov]

Hello @lehakorshun I'm not sure if there are any materials about it. I checked manually this particular case and found that nothing from MVIKotlin was exported to Swift. So I searched through GitHub and found how people are exporting external dependencies. Looks like, when exporting such dependencies, compiler is not smart enough to resolve required artifacts. So we need to specify the exact target.

[lehakorshun]

also when I try to use this solution I have an issue in compile time

Could not resolve com.arkivanov.mvikotlinmvikotlin iosx642.0.0-rc3

[Arkadii Ivanov]

also when I try to use this solution I have an issue in compile time

Could please describe what is the issue?

[lehakorshun]

when I try to build project with suffixes for export, I have

Could not resolve com.arkivanov.mvikotlinmvikotlin iosx642.0.0-rc3

[Arkadii Ivanov]

Could you please provide your build.gradle file?

[lehakorshun]

https://gist.github.com/AlexeyKorshun/618ff2fe16fe25df1171c76bb15d49c3

[lehakorshun]

also, If I remove suffixes, I can use MvikotlinLifecycle and MvikotlinLifecycle, but I can find MvikotlinLifecycleRegistry like as BaseMviView

[lehakorshun]

looks like compiler export the interfaces only.

[Arkadii Ivanov]

I'm not sure at the moment. The build file looks correct. Artifacts with the iosx64 suffix are available. https://dl.bintray.com/arkivanov/maven/com/arkivanov/mvikotlin/mvikotlin-iosx64/2.0.0-rc3/
Unfortunately I don't have much experience with exporting to Swift. This solution supposed to work.
Could you please provide a full error output?

[Arkadii Ivanov]

What Kotlin version are you using?

[lehakorshun]

version - 1.4.0

[lehakorshun]

I think problem is here

Could not determine the dependencies of task ‘afisha sourcelinkDebugFrameworkIosArm64’

[lehakorshun]

link iosx64 in arm task…

[Arkadii Ivanov]

Could you please provide full build log? Or at least full error output?

[Arkadii Ivanov]

Arm64?

[lehakorshun]

[Arkadii Ivanov]

Ok, looks like it incorrectly resolves the target and/or prefix

[Arkadii Ivanov]

It comes from Xcode as env variables

[lehakorshun]

it was when I tried to execute ./gradlew build

[Arkadii Ivanov]

I think the problem is in the getIosTargetName

[lehakorshun]

but if I use ./gradlew packForXcode it is success

[Arkadii Ivanov]

Cause build builds all targets

[Arkadii Ivanov]

But there are no env variables from xcode in this case, so it uses same target name every time

[lehakorshun]

yes after pack task all dependencies in framework

[Arkadii Ivanov]

Yep, don't depend build on pack

[Arkadii Ivanov]

This task is supposed to be executed from Xcode

[lehakorshun]

but I executed it from terminal

[Arkadii Ivanov]

Env variables are passed by xcode, specially for this case

[lehakorshun]

but what is the difference when I execute build task from terminal?

[Arkadii Ivanov]

A special build phase should be setup in Xcode, so it executes ./gradlew packForXcode and passes the configuration and current architecture

[Arkadii Ivanov]

So you choose a build type in Xcode and it passes this info to Gradle

[lehakorshun]

right now I dont launch Xcode and pack task works correct, but if I try to execute build task, I have an error

[lehakorshun]

oh sorry, I’m slowing down

[Arkadii Ivanov]

Yes, this is expected. Since build task builds both targets iosX64 and iosArm64. But there are no env variables from xcode so the getIosTargetName returns same name every time, which is iosX64

[lehakorshun]

in build task we try to build x64 and arm and execute pack task 2 times

[Arkadii Ivanov]

yes

[lehakorshun]

@Arkadii Ivanov thx

[lehakorshun]

big thx )
