[Shubham Singh]

Hii team, I have updated my android project to kotlin 2.0 and I am able to build and run my project for android but there is a KMM module which we publish to be consumed for the iOS project.

When I build that particular module using command ./gradlew build it is showing me some error. Can anyone help me here ?

Also I want add here that I have upgraded my SKIE library also from 0.6.1 to 0.8.0 to transition from kotlin 1.9.22 to kotlin 2.0.0

I am pasting my error here:

Hii @Alejandro Rios , What could be the issue ?

[ian.shaun.thomas]

Just go back to 1.9.22

[Tadeas Kriz]

Hi, I'll take a look and try to reproduce it in SKIE, will keep you updated.

[Tadeas Kriz]

@Shubham Singh Could you share what class from CoreTelephony do you use in your Kotlin code?

[Shubham Singh]

Hi @Tadeas Kriz Will check with the iOS team first then only can revert you back.

[Chrimaeon]

Also @Shubham Singh, Cross-posting without reference in not a good thing and posting long code snippets in the channel as well.

[Tadeas Kriz]

This is a bug in SKIE, we'll fix it in the next patch release

[Shubham Singh]

Hi @Tadeas Kriz can you send me some reference from where you find out that this is a bug ?

[Shubham Singh]

Hii @Chrimaeon I am new to Kotlin Slack and I am sorry if my long message caused any harm

[Tadeas Kriz]

@Shubham Singh I tested class from CoreTelephony in our SKIE playground and I was able to reproduce it. The problem is that with SKIE 0.8.0, we stopped generating fake frameworks for system SDKs. However, the code handling it is supposed to be replaced in the future, so we made it simple. And that simplicity expected all system frameworks to declare an umbrella header, which some of them don't.

[Shubham Singh]

Can we declare an umbrella header from our side ? @Tadeas Kriz

[Shubham Singh]

Due to this only issue I am unable to migrate my android project to Kotlin 2.0.0 😞 . When are we supposed to get a patch for this @Tadeas Kriz ?

[Tadeas Kriz]

Since you're the first who reported it, I'm currently looking into it.

[Shubham Singh]

Okay @Tadeas Kriz, Please keep in touch and do revert when you are done with the fix. Please answer my this question: Can we declare an umbrella header from our side ?

[Tadeas Kriz]

Not sure, but even if you could it'd require deep knowledge

[Tadeas Kriz]

You can try SKIE 0.7.2-preview.2.0.0-RC3 in the meantime

[Shubham Singh]

Is this SKIE 0.7.2-preview.2.0.0-RC3 supports kotlin 2.0.0 version

[Shubham Singh]

??

[Shubham Singh]

@Tadeas Kriz

[Tadeas Kriz]

It might, you'll need to override SKIE's KGP version by putting skie.kgpVersion=2.0.0 in your gradle.properties

[Shubham Singh]

Okay trying @Tadeas Kriz

[Shubham Singh]

See @Tadeas Kriz. I think it will not work for my umbrella module.

[Tadeas Kriz]

Oh yeah, forgot how it works, should be skie.kgpVersion=2.0.0-RC3

[Shubham Singh]

Hi @Tadeas Kriz, It worked !! 💯🥳

[Shubham Singh]

Thanks for your help but please release a fix in 0.8.0 version also.

[Shubham Singh]

As this is the warning that I am getting every time 🙃

[Shubham Singh]

@Tadeas Kriz

[Tadeas Kriz]

Yeah, you're supposed to be getting the warning

[Tadeas Kriz]

It's only to get you unblocked until a fix is released

[Shubham Singh]

When are we fixing it ?

[Tadeas Kriz]

Who knows

[Shubham Singh]

Means till then I'll have to bear with the preview-version only ? @Tadeas Kriz

[Tadeas Kriz]

When it's out, it's out

[Shubham Singh]

Okay, Thanks

[Shubham Singh]

Hi @Tadeas Kriz

[Shubham Singh]

We are still facing some issues as I checked with my ios team.

[Shubham Singh]

We are not getting NativeKt methods after publishing through this preview version of SKIE

[Shubham Singh]

So eventually we are unable to consume that published KMM module in iOS project.

[Shubham Singh]

Hi @Tabrez , can you provide more details here ?

[Tabrez]

Hi Tadeas, There was a error of core-telephony.h file not found. Thank you for sending SKIE version : 0.7.2-preview.2.0.0-RC3 i see the framework is getting generated now.

We also use https://github.com/rickclephas/KMP-NativeCoroutines for observing flows in KMP, it used to generate class functions with NativeKT syntax. it's broken in this version and it's not generating extension fuctions for KMP model functions.

e:g

extension RandomLettersGenerator {
    func getRandomLetters() -> NativeSuspend<String, Error, KotlinUnit> {
        RandomLettersGeneratorNativeKt.getRandomLetters(self)
    }
}

[Tabrez]

i'll try checking it and updating there library if there is a new version available. and update it here.

[Tabrez]

Hi Tadeas, We updated library https://github.com/rickclephas/KMP-NativeCoroutines to v1.0.0-ALPHA-31 it's working fine with this. they have added support for Kotlin 2.0 and we are getting extension functions with NativeKT syntax.. Thanks for you help.

[Tadeas Kriz]

Should be fixed in https://skie.touchlab.co/changelog/0.8.1

[Tabrez]

@Tadeas Kriz Thank you so much.
