Hi, folks!
Has anyone solved this yet?
Uncaught Kotlin exception: org.jetbrains.compose.resources.MissingResourceException

I am facing this issue whenever I build the release XcFramework and try to run it. I don't know what's happening, since I am using the following settings(and that shoudn't happen):

composeMultiplatform = "1.9.0"
kotlin = "2.2.20"

It was supposed to should work fine after CMP 1.8.2.
Also, I can confirm that the resources are present in both simulator and arm64 frameworks, inside the XcFramework. I am running out of options, already read all things related and checked everything.

Update:
Also tried to setup compose resources like this:

compose.resources {
   publicResClass = true
   packageOfResClass = "com.estudia.res"
   generateResClass = auto
}

But nothing changed. Same error.

Which resources do you have in framework ?
And how to build framework ?)

// My variant :)
val frameworkName = "Shared"
val xcf = XCFramework(frameworkName)
listOf(
    iosX64(),
    iosArm64(),
    iosSimulatorArm64()
).forEach {
    it.binaries.framework {
        baseName = frameworkName

        binaryOption("bundleId", "tld.app.${frameworkName}")
        xcf.add(this)
        isStatic = false
    }
}

I have pngs, XMLs and strings. I build the framework with:
assembleXCFramework. Also, already tried with specific task for Debug or Release XcFramework generation. Same result.

[Mateus Bauer]

The problem looks to be with strings. But I honestly don't know why.

[iQQator]

Hmm, I have drawable res (logo.png), and it work good 🙂

For Res to appear in the project, however, I had to reset the caches, File > Invalidate Cache and rebuild framework by ./gradlew assembleAppSharedXCFramework and framework to SPM, and connect it to iOS app

[iQQator]

But can't apply new mechanics for resources at all, drawable doesn't contains logo.png 😉

compose.resources {
    publicResClass = true
    generateResClass = always
}

This doesn't work at all :(

[iQQator]

Try to place it here, but not clean project, nor clean chance and rebuild. No one action provide me access to this resources :)

[Mateus Bauer]

I do have access to resources in code. The problem begins after compiling and using it on iOS as a XcFramework. On android, everything works well tho.

[iQQator]

In my case only composeResources work with XCFramework

[Mateus Bauer]

I am using composeResources

[iQQator]

Which strings in resources do you have, for example
Create example with string 🙂

Using it like that:

text = stringResource(Res.string.hello_message),

And it work

[iQQator]

Picture and text from KMP 🙂, conclusion: I create a Framework Dynamic.
I saw info about a lot of crashes when use static, and resolve it by change it to dynamic

in gradle:

val frameworkName = "Shared"
val xcf = XCFramework(frameworkName)
listOf(
    iosX64(),
    iosArm64(),
    iosSimulatorArm64()
).forEach {
    it.binaries.framework {
        baseName = frameworkName

        binaryOption("bundleId", "tld.app.${frameworkName}")
        xcf.add(this)
        isStatic = false
    }
}

in Package.swift

import PackageDescription

let package = Package(
    name: "Shared",
    platforms: [
        .iOS(.v16),
    ],
    products: [
        .library(
            name: "Shared",
            targets: ["Shared"]),
    ],
    targets: [
        .binaryTarget(name: "Shared", path: "./Shared.xcframework")
    ]

[iQQator]

In your error I assume some problem with strings, you could try to remove it one by one before issue determined, sorry if I can't help you at all :(

[Mateus Bauer]

Let me try compiling it as dynamic. Currently it is static.

[Mateus Bauer]

Tried more a lot of things. Nothing worked. Do you know if I need to import it with SPM? Because im placing it locally, and referencing in Framework Search Paths.

[Mateus Bauer]

Also, removed all the strings and then the problem showed with images. So... the problem is with the resources itself, all them.

[iQQator]

Try to do it with SPM, but I think this not a problem if embed framework itself... I check by embedding a framework directly into project, and it work...
show example how to describe in gradle.kt

In the libs.versions.toml i have this:

composeMultiplatform = "1.9.0"
kotlin = "2.2.20"

[libraries]
kotlin-test = { module = "org.jetbrains.kotlin:kotlin-test", version.ref = "kotlin" }

[plugins]
composeMultiplatform = { id = "org.jetbrains.compose", version.ref = "composeMultiplatform" }
composeCompiler = { id = "org.jetbrains.kotlin.plugin.compose", version.ref = "kotlin" }
kotlinMultiplatform = { id = "org.jetbrains.kotlin.multiplatform", version.ref = "kotlin" }

[iQQator]

My sourceSet looks like this

[iQQator]

My shared folder is:

[Mateus Bauer]

I gave it a last try with SPM (local) and it surprisingly worked. Everything.

[Mateus Bauer]

For future people:
Try it with SPM. Create a folder with a configured Package.swift and your .xcframework. Then, add the dependency(the folder) with SPM, locally.

[Mateus Bauer]

@iQQator thank you very much! Saved me from days of suffering 🤣
