Wondering if anyone has run into an issue like this when trying to build for a real iPhone target.

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_SharedCodeEventUiModel", referenced from: objc-class-ref in EventUI.o

I assume I need to change my gradle setup but I'm unsure what exactly I need to change.

I was able to get the app to install by changing my iosPreset value to iosArm64 but I'm now running into a crash when the app actually starts:

dyld: Library not loaded: @rpath/SharedCode.framework/SharedCode

In (xcode -> project settings -> Select target -> general -> frameworks, libraries and embedded content), you should see your shared KMP module. Make sure you select one of the embed options.

I didn't have it set to embed & sign (it was set to do not embed) unfortunately I still see the same crash. Is there a way to verify I'm bringing in the right framework?

[zsperske]

right now its called Pods_MyApp.framework

[yousefa2]

Are you packaging your KMP module as a framework or as Cocoapod? Each have a different setup and the name Pods_MyApp.framework implies you are using Cocoapods.

my gradle setup is based on a dated example and I'm not very familiar with how it works

kotlin {
    targets {
        fromPreset(presets.android, 'android')

        final def iOSTarget = System.getenv('SDK_NAME')?.startsWith("iphoneos") \
                          ? presets.iosArm64 : presets.iosX64

        fromPreset(iOSTarget, 'ios') {
            binaries {
                framework()
            }
        }
    }

...

task packForXCode {
    def buildType = project.findProperty("kotlin.build.type") ?: "DEBUG"
    dependsOn "link${buildType.toLowerCase().capitalize()}FrameworkIos"

    doLast {
        def srcFile = kotlin.targets.ios.binaries.getFramework(buildType).outputFile
        def targetDir = getProperty("configuration.build.dir")
        copy {
            from srcFile.parent
            into targetDir
            include 'SharedCode.framework/**'
            include 'SharedCode .framework.dSYM'
        }
    }
}

thanks for the help so far, if you know of some docs I should be reading, I'd be happy to read those instead

Looks like it’s packaged as a framework called SharedCode .. have a look at this https://play.kotlinlang.org/hands-on/Targeting%20iOS%20and%20Android%20with%20Kotlin%20Multiplatform/06_SettingUpKotlinFramework . It contains all the steps needed.

much appreciated!

[zsperske]

worked perfectly, thank you!

hey @yousefa2 sorry to bug you again, but do you have any experience with building an archive to upload to test flight?

performing that build leads me to a compilation error claiming "no such module: "'SharedCode' " on an import SharedCode in one of my swift files
