Symbol not found at runtime

[sjudd]

Platform

Apple

Installed

Swift Package Manager

Version

0.18.0 and 0.19.0

Steps to Reproduce

I followed the instructions here to add the gradle plugin: https://docs.sentry.io/platforms/kotlin/guides/kotlin-multiplatform/. I set the version in swift package manager for the sentry to 8.55.1 when using sentry-kotlin-multiplatform 0.19.0, then when that had the runtime error below, I switched to 0.18.0 and 8.53.2, but I see the same issue.

The sentry gradle plugin is in the plugins list in the build.gradle.kts file in the shared module.

My sentry setup code is in commonMain and is pretty simple:

package com.withandy.mobile

import io.sentry.kotlin.multiplatform.Sentry

fun initializeSentry(dsn: String, environment: String) {
    Sentry.init { options ->
        options.dsn = dsn
        options.environment = environment
    }
}

I get this runtime error when I run the iOS app on the simulator (I haven't tried a real device):

dyld[98376]: Symbol not found: _OBJC_CLASS_$_PrivateSentrySDKOnly

Expected Result

I'd like it to not crash at runtime

Actual Result

It crashes

hi which xcode version are you using?

[sjudd]

Hi, I'm using Xcode 16.2 (16C5032a)

For what it's worth, I tried updating to 16.4 and now I'm running into a linker issue:

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.11.1/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

Alternatively people also found success using the new spmForKmp plugin.

Unfortunately I cannot reproduce this issue but I'd also recommend clearing caches, deriveddata etc.. as well before and make sure that your Sentry Cocoa dependency in SPM is set to the exact version
