Platform

Apple, Android

Installed

Swift Package Manager

Version

0.5.0

Steps to Reproduce

1. Add io.sentry:sentry-kotlin-multiplatform:0.5.0 to sourceSets.commonMain.dependencies in build.gradle.kts

kotlin {
    // snip

    listOf(
        iosX64(),
        iosArm64(),
        iosSimulatorArm64()
    ).forEach { iosTarget ->
        iosTarget.binaries.framework {
            baseName = "ComposeApp"
            isStatic = true
        }
    }

    sourceSets {
        commonMain.dependencies {
            implementation("io.sentry:sentry-kotlin-multiplatform:0.5.0")
        }
    }
}

2. Add sentry-cocoa using sentry-wizard -i ios

3. Move initialize code using Shared initializer

// commonMain/SentryInit.kt

fun initializeSentry() {
    Sentry.init { /* setting */ }
}

// androidMain/MainApplication.kt
class MainApplication : Application() {
    override fun onCreate() {
        super.onCreate()
        initializeSentry()
    }
}

// iosMain/iOSApp.swift
import ComposeApp

@main
struct iOSApp: App {
    init() {
        SentryInitKt.intializeSentry()
    }
}

4. Build both Android (on Android Studio) and iOS (on XCode)

Expected Result

Build success.

Actual Result

• Android: Build success and Sentry got works well.
• iOS: Link app failed with the message below.

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_SentryId", referenced from:
       in ComposeApp[arm64][2727](libio.sentry:sentry-kotlin-multiplatform-cache.a.o)
ld: symbol(s) not found for architecture arm64

Hi which version of cocoa sdk are you using?

[buenaflor]

Not sure which version is added through the wizard

[buenaflor]

We might have to update our KMP SDK to handle sentry cocoa versions higher than 8.22.0

Otherwise we recommend installing the KMP SDK as per our guide: https://docs.sentry.io/platforms/kotlin-multiplatform/

[buenaflor]

This problem should be fixed with the next release 0.6.0

[k-ogawa-1988]

which version of cocoa sdk are you using?

Using 8.25.0.

I'll try using cocoapods.

[buenaflor]

fyi currently our KMP SDK only works with versions up to 8.21.0, please look at this table to check what works

[buenaflor]

Our next release will support versions starting from 8.22

[buenaflor]

Fixed by 0.6.0.

Feel free to comment if there is still an issue
