Hi team, hope you are doing well
From the iOS native, I need to set delegate for NSURLSession. So is there any way to pass NSURLSession or NSURLSessionDelegate back to iOS? Any of your suggestions will make my day. Thanks.

You can use the usePreconfiguredSession method inside the engine block. Here is an example:

val client = HttpClient(Darwin) {
    val delegate = KtorNSURLSessionDelegate()
    val session = NSURLSession.sessionWithConfiguration(
        NSURLSessionConfiguration.defaultSessionConfiguration(),
        delegate,
        delegateQueue = NSOperationQueue()
    )
    engine {
        usePreconfiguredSession(session, delegate)
    }
}

Thanks @Aleksei Tirman [JB]
Currently, we used ktor version 2.1.0, also using handleChallenge AND configureSession in HttpClient(Darwin).
Following by new version ktor
https://api.ktor.io/ktor-client/ktor-client-darwin/io.ktor.client.engine.darwin/-darwin-client-engine-config/use-preconfigured-session.html

"Set a session to be used to make HTTP requests. If the preconfigured session is set, configureSession and handleChallenge blocks will be ignored."

Do you have any suggestions?

hi @Aleksei Tirman [JB]
We used CertificatePinner.Builder(), configureSession and handleChallenge for config http. Under your suggestion, using new NSURLSession and usePreconfiguredSession will ignore our previous config NSURLSession. Do you have any ideas please feel free to share. Thanks

The problem is that the primary constructor of the KtorNSURLSessionDelegate is internal so there is no way to pass the ChallengeHandler to it.

[Aleksei Tirman [JB]]

Would it solve your problem if the constructor were public?

[phong le]

yup, the sound is good, then we can set KtorNSURLSessionDelegate from the out side, or we can have a new func like configureSession, something like that

public fun configureSessionDelegate(block: NSURLSessionDelegate.() -> Unit)

How about your ideals @Aleksei Tirman [JB]?

I don’t have a specific preference. Can you please file an issue then?
