Hey everyone 👋,
Running linkPodDebugFrameworkIosFat gives me

fatal error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: /Users/moussa/Desktop/MoussaWork/Companies/IOHK/atala-prism-apollo/base-asymmetric-encryption/build/bin/iosArm64/podDebugFramework/ApolloBaseAsymmetricEncryption.framework/ApolloBaseAsymmetricEncryption and /Users/moussa/Desktop/MoussaWork/Companies/IOHK/atala-prism-apollo/base-asymmetric-encryption/build/bin/iosX64/podDebugFramework/ApolloBaseAsymmetricEncryption.framework/ApolloBaseAsymmetricEncryption have the same architectures (arm64) and can't be in the same fat output file

Error simplified, iosArm64 & iosX64 have the same architectures (arm64) and can’t be in the same fat output file. How do I investigate this error or at least try to figure out the root cause of that issue?

Notes:
• Using the iOS new hierarchy only ios()

[Daniel Seither]

The problem you’re likely running into here is that Apple Silicon Macs (M1, M2) and iPhones are using the same architecture (arm64), meaning that you can’t put a simulator build (to be run on a Mac) and a device build (to be run on a phone/tablet) into the same framework binary anymore. Apple’s solution for this is XCFrameworks, which is a directory structure containing multiple frameworks. See also https://kotlinlang.org/docs/multiplatform-build-native-binaries.html#build-xcframeworks for how to do this.

I wonder why it says iosArm64 and iosX64 though, because the latter shouldn’t have the arm64 architecture. Have you maybe mixed up iosX64 (which is the simulator build for Intel Macs) and iosSimulatorArm64 somewhere?

[Moussa]

@Daniel Seither I understand. But, I’m not doing anything different than having ios source set so this is really weird that is passing in other modules with the same configuration

[Daniel Seither]

I’m sorry, I’m an iOS dev and not a Gradle expert in any way. Maybe someone with more knowledge of the KMM build config can take a look here?

Workaround: I ignore that task for now until I get a better handle on it. It could be caused by removing iosSimulatorArm64

tasks.matching {
    fun String.isOneOf(values: List<String>): Boolean {
        for (value in values) {
            if (this == value) {
                return true
            }
        }
        return false
    }

    it.name.isOneOf(
        listOf(
            "linkPodReleaseFrameworkIosFat",
            ":linkPodReleaseFrameworkIosFat", "linkPodDebugFrameworkIosFat",
            ":linkPodDebugFrameworkIosFat"
        )
    )
}.all {
    this.enabled = false
}
