Does the library support iosArm64() and iosSimulatorArm64() targets? I can see them defined in the gradle files, but when I'm trying to compile a KMM project I get the following error:

FAILURE: Build failed with an exception.

* What went wrong:

I think I have misconfigured the dependency for iOS, but not sure where.

Portion of the libs.versions.toml file:

[versions]
emoji = "0.21.0"

emoji-google-compat = { group = "com.vanniktech", name = "emoji-google-compat", version.ref = "emoji" }
emoji-material = { group = "com.vanniktech", name = "emoji-material", version.ref = "emoji" }
emoji-core = { group = "com.vanniktech", name = "emoji", version.ref = "emoji" }

Portion of the build.gradle.kts file

kotlin {
    androidTarget {}
    jvm()
    listOf(
        iosArm64(),
        iosSimulatorArm64(),
    ).forEach {
        it.binaries.framework {
            baseName = "Common"
            isStatic = false
            binaryOption("bundleId", "com.blahblah.common")
        }
    }

    sourceSets {
        commonMain.dependencies {
            ...
        }
        jvmMain.dependencies {
            implementation(libs.emoji.google.compat)
        }
        androidMain.dependencies {
            implementation(libs.emoji.google.compat)
            implementation(libs.emoji.material)
        }
        iosMain.dependencies {
            implementation(libs.emoji.core)
        }
    }
}

And the code that tries to import and use it in commonMain. (FYI when the implementation is "actual"-ised in androidMain all compiles and works ok):

package com.blahblah.common.emoji

import com.vanniktech.emoji.emojiInformation

object EmojiManager {

    fun parse(input: String?): EmojiInformation {
        val result = input?.trim().emojiInformation()
        ...
    }
}

[vanniktech]

implementation(libs.emoji.core) should be in commonMain.dependencies

Oh, I mixed up the sample codes. Essentially - I tried that, it didn't compile either. So I got back to expect / actual per platform, that is:

        iosMain.dependencies {
            implementation(libs.emoji.core)
        }

for

// commonMain
package com.blahblah.common.emoji

expect object EmojiManager {
    fun parse(input: String?): EmojiInformation
}

// iosMain
package com.blahblah.common.emoji

import com.vanniktech.emoji.emojiInformation // error - unresolved symbol

actual object EmojiManager {
   ....
}

[vanniktech]

This should work though.

Could you maybe add an iOS target in the sample app in this repo? This way you could verify it's working, and also have a reference for others

I currently don't have the time but yes, ideally this should be done.
