构建iOS应用程序时Kotlin / Native compileKotlinIosX64任务失败

我有一个Kotlin Multiplatform项目。我最近更新到Kotlin 1.4-M2（我需要它来解决Ktor的某些问题）。更新所有必需的库，解决所有gradle问题并成功编译我的Android项目之后，现在在构建iOS应用时遇到以下错误：

Task :shared:compileKotlinIosX64
e: Compilation failed: Could not find declaration for unbound symbol org.jetbrains.kotlin.ir.symbols.impl.IrSimpleFunctionPublicSymbolImpl@56f11f08
* Source files: [all shared folder kt files]
 * Compiler version info: Konan: 1.4-M2 / Kotlin: 1.4.0
 * Output kind: LIBRARY
e: java.lang.IllegalStateException: Could not find declaration for unbound symbol org.jetbrains.kotlin.ir.symbols.impl.IrSimpleFunctionPublicSymbolImpl@56f11f08
    at org.jetbrains.kotlin.ir.util.ExternalDependenciesGeneratorKt.getDeclaration(ExternalDependenciesGenerator.kt:76)

奇怪的是，在源文件中它显示了共享代码文件夹中的所有文件。我检查了一下，绝对所有的kt文件都出现在其中。因此，我的猜测是在构建共享代码时这是一个问题，但似乎并不是任何库都特定的。

这是我的build.gradle.kts看起来的稍微简化的版本：

plugins {
    kotlin("multiplatform")
    kotlin("native.cocoapods")
    id("kotlinx-serialization")
    id("com.android.library")
    id("io.fabric")
}

// CocoaPods requires the podspec to have a version.
version = "1.0"

tasks {
    withType<KotlinCompile> {
        kotlinOptions {
            jvmTarget = "1.8"
        }
    }
}

kotlin {
    ios()
    android()

cocoapods {
    // Configure fields required by CocoaPods.
    summary = "Some description for a Kotlin/Native module"
    homepage = "Link to a Kotlin/Native module homepage"
}

sourceSets {
        val commonMain by getting {
            dependencies {
                implementation("org.jetbrains.kotlin:kotlin-stdlib-common")
                implementation("org.jetbrains.kotlinx:kotlinx-serialization-runtime:$serializationVersion")
                api("org.kodein.di:kodein-di:7.1.0-kotlin-1.4-M3-84")
                implementation("io.mockk:mockk:1.9.2")

                api("org.jetbrains.kotlinx:kotlinx-coroutines-core:$coroutinesVersion")

                api("com.russhwolf:multiplatform-settings:$multiplatformSettingsVersion")

                implementation("io.ktor:ktor-client-core:$ktorVersion")
                implementation("io.ktor:ktor-client-json:$ktorVersion")
                implementation("io.ktor:ktor-client-logging:$ktorVersion")
                implementation("io.ktor:ktor-client-serialization:$ktorVersion")
            }
        }
}
}

库的版本如下：

val ktorVersion = "1.3.2-1.4-M2"
val kotlinVersion = "1.4-M2"
val coroutinesVersion = "1.3.7-native-mt-1.4-M2"
val serializationVersion = "0.20.0-1.4-M2"
val multiplatformSettingsVersion = "0.6-1.4-M2"

值得一提的是，这在使用1.3.72时在iOS中正确构建。
