在Cocoapod中导入Kotlin/Native框架

Question

我正在尝试在私有CocoaPod中添加使用Kotlin/Native构建的销售框架,但是我收到错误:

• 我用Kotlin/Native生成了一个iOS框架.
• 我将框架文件夹(由Konan编译/生成)复制到我的自定义pod文件夹中
• 在podspec中,我在"vendored_frameworks"列表中添加了框架路径
• 我发布了 pod repo push myCocoapodsRepo myProject.podspec --verbose"
• 我收到一个错误:

[iOS] xcodebuild: fatal error: lipo: input file (/Users/jeandaube/Library/Developer/Xcode/DerivedData/App-auugdpsmbbpvarfzghxatkvwftsn/Build/Products/Release-iphonesimulator/App.app/Frameworks/MyProject.framework/MyProject) must be a fat file when the -remove option is specified

我是否应该以某种方式改变我首先使用Konan导出框架的格式？

您收到错误是因为默认情况下,Kotlin Native仅为单个体系结构生成二进制文件.CocoaPods尝试将其视为具有多种体系结构的"胖"二进制文件时失败.因为你无论如何都需要多个架构(至少arm64用于设备而x86_64用于模拟器)我正在使用的方法是创建两个架构然后将它们合并lipo .然后可以通过CocoaPods 提供生成的胖框架或者只是拖动/ drop安装在Xcode中.

def outputDirectory = "$export_dir/$projectName/$projectVersion"
def outputFramework = "$outputDirectory/${projectName}.framework"

konanArtifacts {
    // Declare building into a framework, build arm64 for device, x64 for simulator                                                      
    framework(projectName, targets: ['ios_arm64', 'ios_x64' ]) {
        // The multiplatform support is disabled by default.                                   
        enableMultiplatform true
    }
}

// combine original arm64 and x64 libraries into a single library in
// the exported framework folder
task combineArchitectures(type: Exec, dependsOn: compileKonanLibrary) {
    executable 'lipo'
    args = [
            '-create',
            '-arch',
            'arm64',
            new File(compileKonanLibraryIos_arm64.artifact, 'Library'),
            '-arch',
            'x86_64',
            new File(compileKonanLibraryIos_x64.artifact, 'Library'),
            '-output',
            "$outputFramework/Library"
    ]
}

// export the arm64 (doesn't matter which really) framework, skipping
// the library binary itself
task exportFramework(type: Copy, dependsOn: compileKonanLibrary) {
    from compileKonanLibraryIos_arm64.artifact
    into outputFramework
    exclude projectName
    finalizedBy combineArchitectures
}

// build a pod spec by copying and updating a template file
task exportPodspec(type: Copy) {
    from "Library.podspec"
    into outputDirectory
    filter {
        it.replaceAll('@@projectName@@', projectName)
            .replaceAll('@@projectVersion@@', projectVersion)
    }
}

task export {
    dependsOn "exportFramework"
    dependsOn "exportPodspec"
}
