Question

我正在尝试在iOS上使用Kotlin多平台代码（使用Ktor和Kotlin协程）。该框架是正确生成的，可以毫无问题地调用某些公开的类/方法。但是，如果我尝试添加以下内容（例如，在https://github.com/JetBrains/kotlinconf-app/blob/master/konfios/konfswift/ui/UI.swift中这样做）。我得到“使用未声明的类型'KotlinCoroutineContext”（并且在SharedCode.h中看到它不存在）

import Foundation
import UIKit
import SharedCode


public class CoroutineDispatcher: Kotlinx_coroutines_core_nativeCoroutineScope {
    override public func dispatch(context: KotlinCoroutineContext, block: Kotlinx_coroutines_core_nativeRunnable) {
        DispatchQueue.main.async {
            block.run()
        }
    }
}

共享代码的gradle文件包括以下内容（使用Kotlin 1.3.11，Ktor 1.0.1和Coroutines 1.0.1以及Gradle 4.7）

    commonMain.dependencies {
        implementation "org.jetbrains.kotlin:kotlin-stdlib-common:${Versions.kotlin}"
        implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core-common:${Versions.kotlinCoroutines}"
        implementation "org.jetbrains.kotlinx:kotlinx-serialization-runtime:${Versions.kotlinxSerialization}"

        implementation "io.ktor:ktor-client-core:${Versions.ktor}"
        implementation "io.ktor:ktor-client-json:${Versions.ktor}"

    }

    androidMain.dependencies {
        implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:${Versions.kotlin}"
        implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:${Versions.kotlinCoroutines}"

        implementation "io.ktor:ktor-client-core-jvm:${Versions.ktor}"
        implementation "io.ktor:ktor-client-json-jvm:${Versions.ktor}"
    }

    iOSMain.dependencies {
        implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core-native:${Versions.kotlinCoroutines}"
        implementation "org.jetbrains.kotlinx:kotlinx-serialization-runtime-native:${Versions.kotlinxSerialization}"

        implementation "io.ktor:ktor-client-ios:${Versions.ktor}"
        implementation "io.ktor:ktor-client-core-ios:${Versions.ktor}"
        implementation "io.ktor:ktor-client-json-ios:${Versions.ktor}"
    }

我怀疑这个问题可能是那些符号未显式公开的（对于协程依赖性，也尝试使用api而不是implementation来解决，但这无济于事）。

更新：

尝试了新发布的Kotlin v1.3.20，但现在受到关注

Answer 1

我在更新中遇到了相同的问题

The abi versions don't match. Expected '[5]', found '2'1

基本上，科特林1.3.20，Ktor需要升级到1.1.2，然后摇篮4.10是需要使用最新科特林天然。这是因为摇篮元数据的

在进行此更新之前，我开始遇到有关构建Kotlin序列化程序的iOS工件的新问题：

error: compilation failed: Can’t locate polymorphic serializer definition

要解决这个问题，我除去@Serializable从类注释和设置在KSerializer界面分离。

带有iOS的Kotlin多平台：“使用未声明的类型'KotlinCoroutineContext'”
