MacOS Kmp cannot install ktor dependency - xcode

Question

Working with Kotlin KMP and targeting macos and I am having trouble installing a ktor dependency.
Here is my shared module gradle file
plugins {
kotlin("multiplatform")
id("kotlinx-serialization")
kotlin("native.cocoapods")
id("com.android.library")
}
version = "1.0"
kotlin {
android()
jvm()
val iosTarget: (String, KotlinNativeTarget.() -> Unit) -> KotlinNativeTarget =
if (System.getenv("SDK_NAME")?.startsWith("iphoneos") == true)
::iosArm64
else
::iosX64
iosTarget("ios") {}
macosX64("macos")
cocoapods {
summary = "Some description for the Shared Module"
homepage = "Link to the Shared Module homepage"
// ios.deploymentTarget = AppleSdk.iosDeploymentTarget
// osx.deploymentTarget = AppleSdk.osxDeploymentTarget
frameworkName = "shared"
}
sourceSets {
val commonMain by getting {
dependencies {
// ktor dependencies needs to use old coroutine version
// https://youtrack.jetbrains.com/issue/KT-46697
implementation(Kotlinx.coroutineCore)
// Koin
implementation(Koin.core)
implementation(Koin.test)
// Ktor
implementation(Ktor.clientCore)
implementation(Ktor.clientJson)
implementation(Ktor.clientLogging)
implementation(Ktor.clientSerialization)
// serialization
implementation(Kotlinx.serializationCore)
}
}
val commonTest by getting {
dependencies {
implementation(kotlin("test-common"))
implementation(kotlin("test-annotations-common"))
}
}
val androidMain by getting {
dependencies {
implementation(Ktor.clientAndroid)
}
}
val androidTest by getting {
dependencies {
implementation(kotlin("test-junit"))
implementation(Test.junit)
}
}
val iosMain by getting {
dependencies {
// "io.ktor:ktor-client-ios:1.6.0"
implementation(Ktor.clientIos)
}
}
val iosTest by getting
val jvmMain by getting {
dependencies {
implementation(Ktor.clientJvm)
}
}
val jvmTest by getting {
dependencies {
implementation(kotlin("test-junit"))
implementation(Test.junit)
}
}
val macosMain by getting {
dependencies {
// "io.ktor:ktor-client-cio:1.6.0"
implementation(Ktor.clientCio)
}
}
val macosTest by getting
}
}
My solution builds in android studio and I am able to run my solution in xcode for ios. However when I get to the macos target I get this error in xcode:
duplicate symbol '_kclass:io.ktor.network.sockets.SocketTimeoutException' in:
{redacted}/shared/build/cocoapods/framework/shared.framework/shared(result.o)
ld: 1 duplicate symbol for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
When I remove the macos ktor dependency it builds just fine. I don't have any extra build gradles that are modified right now, so I know that I am not installing ktor in any extra places currently. I do not get why ios works and macos fails. I The way that I read that xcode error it seems like there is a duplicate ktor method/class? Any help would be greatly appreciated! I am modeling a lot after this repo as well https://github.com/joreilly/PeopleInSpace and the only major difference I can see is that I am still using cocoa pods and the other dev migrated to swift package manager

According to the documentation, Ktor's CIO engine is JVM-only. Try using curl one:
val macosMain by getting {
dependencies {
implementation("io.ktor:ktor-client-curl:$ktor_version")
}
}
