[Farid Benhaimoud]

Hello all,

I was very happy that my project did run on android. But when I tried to run the project on iOS it failed 😞 . I tested it with adding and deleting out the decompose dependencies in my clean branch and it failed running iOS when adding those dependencies and succeeded when commenting them out. I am not sure that this is the issue but if somebody could help me out here it would be wunderfull. I have made the repo public.

any help would be great. I spend the whole weekend trying stuff but unfortunately nothing worked.

[Arkadii Ivanov]

Is it a runtime crash or a build failure? Is there an error message or a stack trace?

[Farid Benhaimoud]

I get this log. Don’t really understand what is means

[Arkadii Ivanov]

Can you try making extensions-compose-jetbrains implementation, not api?

[Farid Benhaimoud]

Doesn’t change. Build still fails

[Arkadii Ivanov]

Can you share more of the error?

[Arkadii Ivanov]

The first screenshot is cut at the top

[Arkadii Ivanov]

Oh, your Essenty version is pretty low. Try upgrading Decompose to 2.0.0 and Essenty to 1.1.0

[Arkadii Ivanov]

And don't make extensions compose api, it could be implementation

[Farid Benhaimoud]

ok i will try

[Arkadii Ivanov]

Also, you have extensions-compose-jetbrains in common, but no Compose?

[Farid Benhaimoud]

Ah yeah haha. I did delete extensions-compose-jetbrains for now and it works.

[Farid Benhaimoud]

Next step is to add these classes manually?

[Arkadii Ivanov]

Yep, they are here: https://github.com/arkivanov/Decompose/tree/master/sample/app-ios/app-ios/DecomposeHelpers

[Farid Benhaimoud]

Thanks you very much once again 🌹

[Arkadii Ivanov]

You are welcome! Glad your problem was solved.

[Farid Benhaimoud]

Sorry Arkadii, here I am again. A couple of things.
I have added the helper classes in my android studio and they were not visible in XCode while they were present in my folder when I opened it in my finder.
After that I added the classes manually in XCode itself. But I have issues with the Value classes. I must be doing something wrong. I am not using KMMBridge by the way

[Arkadii Ivanov]

Exporting decompose should make those classes visible from Xcode. Please try building the Xcode project. The build should fail but it should make the classes available.

[Farid Benhaimoud]

Unfortunately it keeps failing the build and not recognize the import.

[Arkadii Ivanov]

Perhaps something related to gradle? You can try adding your own class to Shared framework, then build Xcode, and see if it's available.

[Farid Benhaimoud]

It might has to do something with this. In your decompose lib you are not using the listOf and in the confetti app they are not filtering based on it.konanTarget. I will research how to change this properly

targets
        .filterIsInstance<org.jetbrains.kotlin.gradle.plugin.mpp.KotlinNativeTarget>()
        .filter { it.konanTarget.family == org.jetbrains.kotlin.konan.target.Family.IOS }
        .forEach {
            it.binaries.framework {
                baseName = "Shared"
                export(libs.decompose)
                export(libs.essenty)
                export(libs.reaktive)
            }
        }

    listOf(
        iosX64(),
        iosArm64(),
        iosSimulatorArm64()
    ).forEach {
        it.binaries.framework {
            baseName = "shared"
        }
    }

[Arkadii Ivanov]

You are setting the framework name twice with different names. Maybe that's the reason.

[Arkadii Ivanov]

Oh, try moving target definitions above exporting!

[Farid Benhaimoud]

That doens’t work

[Arkadii Ivanov]

Now you are exporting twice 🙂

[Arkadii Ivanov]

I mean that targets should be defined before exporting, not after.

[Farid Benhaimoud]

I deleted the targets and I get code completion in xcode but it keeps showing Error and the weird thing is I can see the classes in local changes but not in folder structure

[Farid Benhaimoud]

I think I have to talk with my iOS college tomorrow. Because I am not an iOS developer

[Arkadii Ivanov]

There is no val in Swift, did you mean let?

[Farid Benhaimoud]

i meant var sorry my bad

[Farid Benhaimoud]

The xcode ide also changes the SignUpUiState model i have in kotlin in SignupComponentSignUpUiState haha

[Farid Benhaimoud]

it concatonates the class and model

[Arkadii Ivanov]

Yeah. Either put the model top-level, or inside but name it just Model

[Farid Benhaimoud]

You are correct it was inside my interface. I will move it up. So xcode knows my class are there but it keeps failing because of unknown attribute ObservableObject and ObservableValue. I will add the swift files in xcode manually and see what happens

[Arkadii Ivanov]

Yes, you have to add those files manually

[Farid Benhaimoud]

I give up for today. it’s been a long day. Thanks for all the help once again. I will continue tomorrow

[Arkadii Ivanov]

Oh, ObservableObject compose from SwiftUI! https://developer.apple.com/documentation/combine/observableobject

[Arkadii Ivanov]

The doc says iOS 13.0+, what's your target iOS version?

[Arkadii Ivanov]

And it appears that you are looking at outdated sample? Check out the latest: https://github.com/arkivanov/Decompose/blob/master/sample/app-ios/app-ios/CounterView.swift

[Arkadii Ivanov]

The old way (what you are trying to do): annotate properties of type ObservableValue with @ObservedObject (not @ObservableObject).
The new way: add StateValue property wrapper to your project and use it instead.

[Farid Benhaimoud]

Ah thanks. I will look into it when I get back home. I went outside for a walk. Get some fresh air haha

[Arkadii Ivanov]

Doing the same now 😁

[Farid Benhaimoud]

Alrighty then. It works 😃. Thnx Arkadii. Tomorrow I will start iOS-ing.
