I’m having the same issue, need to set

NSURLSessionConfiguration

into

IosClientEngineConfig

but don’t know how to set. I’m using

ktor-client-iOS

1.6.7

You can use the

configureSession

method to mutate an

NSURLSessionConfiguration

:

val client = HttpClient(Darwin) { // `Ios` for Ktor 1.6.7
    engine {
        configureSession { // this: NSURLSessionConfiguration
            // mutate configuration here
        }
    }
}

Hi @Aleksei Tirman [JB] Thanks for your suggestion. Currently in my situation, I want to inject a

NSURLSessionConfiguration

from native into

HttpClient(Darwin)

Ex: • On Swift code, I have a

URLSessionConfiguration.default

& want to pass it to KMM • On KMM code, how can we config for this case with

HttpClient(Darwin)

val client =  HttpClient(Darwin) {
        config(this)
        engine {
            configureSession {  
                // How can I inject NSURLSessionConfiguration from native here
            }
        }
    }

You can find an information about using Swift library from Kotlin code here. Unfortunately, there is no way to pass a configuration object and you can only mutate the one that is created by Ktor.

In Ktor 2.1.0 (will be released soon) you can use preconfigured session object like so:

val config = NSURLSessionConfiguration.defaultSessionConfiguration()
val session = NSURLSession.sessionWithConfiguration(config)

val client = HttpClient(Darwin) {
    engine {
        usePreconfiguredSession(session)
    }
}

It’s really helpful information. Thanks for your quickly response. I will wait for

2.1.0

version to update it.
