KMM error: This API is internal in ktor and should not be used. It could be removed or changed without notice

Question

将 Xcode 更新到 13.0 后，我无法运行我的 iOS 使用 Kotlin Multiplatform 的应用程序。
构建失败并显示 Command PhaseScriptExecution failed with a nonzero exit code，它表示错误是：

Task :shared:compileKotlinIos FAILED
e: /Users...path.../KtorClient.kt: (134, 17): This API is internal in ktor and should not be used. It could be removed or changed without notice.

更新到 Xcode 13 后我们也有类似的错误，但它总是与共享 KMM 库有关，JDK 等...此错误显示多次：
> Process ‘command ‘/Library/Java/JavaVirtualMachines/jdk-11.0.12.jdk/Contents/Home/bin/java’' finished with non-zero exit value 1

第 134 行KtorClient.kt：

override suspend fun createPassword(email: String, password: String): CreatePasswordResponse {
        return client.post {
            url {
                path("v1", "user", "create_password")
                body = LoginRequest(email, password)
            }
            headers {
/*134.line*/    append(HttpHeaders.ContentType, ContentType.Application.Json)
            }
        }
    }

我们尝试删除 XCWorkspace、Podfile.lock、Pods 文件夹，然后重新安装 pod，删除派生数据，但没有任何帮助。

我们也尝试了不同版本的 Ktor，JDK，没有任何帮助。

另外这个在 Internet 上找到的命令也没有帮助（他们说你应该运行在更新 Xcode 之后）：

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

这是 Kotlin 中的 known issue of Ktor, related to this fix。

documentation 是这样说的：

Note that the StringValuesBuilder class that exposes the append function is incorrectly marked with the InternalAPI annotation. This issue will be fixed in v2.0.0. As a workaround, you can add the @OptIn(InternalAPI::class) annotation to explicitly opt-in to use this API.

您可以使用 @OptIn(InternalAPI::class) 选择加入您的特定行，或将此添加到您的共享模块 build.gradle.kts 以对整个模块生效：

kotlin {
    // ..
    sourceSets {
        all {
            languageSettings.optIn("io.ktor.util.InternalAPI")
        }
        // ...
    }
}
