Boringssl error when using IOS Engine

I using **ktor_version = '1.1.2'** and **implementation "io.ktor:ktor-client-ios:$ktor_version"**
When I call post request from swift code to kotlin-native, so I don't see reponse from server (Android call success). Please help me!!! Thank you.
This is my code
//Swift
```
override func viewWillAppear(_ animated: Bool) {
CommonKt.loginTestAbc(callback :self)
}
```

//Kotlin-ios
```
actual class HttpClientEngineHelper {

actual fun getEngine(): HttpClientEngine {
val config = IosClientEngineConfig()
config.configureRequest {
// setTimeoutInterval(5.0)
}
return IosClientEngine(config)
}
}
```

//Kotlin common
```
private val client : HttpClient by lazy {
HttpClient(HttpClientEngineHelper().getEngine()) {

}
}
```

```
//MARK: call api
fun login(callback : OnListenerResponseApi) {
LogVnd.r("login")
try {
GlobalScope.launch { // launch new coroutine in the scope of runBlocking
LogVnd.r("login launch")
reqLogin(ReqLoginModel("username", "password"), callback)
}
} catch (e : Exception){
LogVnd.r(e.message)
callback.onError(e.message)
}
}

suspend fun reqLogin(reqLoginModel: ReqLoginModel, callback: OnListenerResponseApi) {
try {
LogVnd.r("reqLogin")
val res = client.call(loginUrl) {
method = HttpMethod.Post
addHeader(headers)
body = TextContent(Json.stringify(ReqLoginModel.serializer(), reqLoginModel), ContentType.Application.Json)
LogVnd.d(ApiHelper.TAG, "$body")
}.response
LogVnd.d(
TAG,
"RES $res"
)
processResponseData(res, ResLoginModel::class, callback)
} catch (e: Exception) {
LogVnd.e(e)
callback.onException()
}
}

```
