I'm new to Kotlin Multiplatform, and I'm trying to make my own app. For now, my project work in Android simulator: I'm correctly connecting to my database and all. But in my iOS simulator, I'm not even able to connect to it, even though I already checked my internet connection and it works just fine. It fails systematically at the initialization I think, because I'm not even trying to get my values userMail/userPassword to sign in supabase for authentification via POST request... Here are the logs.

Any help to debug this will be greatly appreciated, if you need any more informations don't hesitate to tell me.
- UPDATE -
I've been on differents forums and the official Ktor documentation, and managed to solve my problem. I manually initialized the Darwin engine in my SupabaseService. I created a KtorHttpClient in commonMain which I implemented as an actual function in iosMain, like this:
package org.example.job.service
import io.ktor.client.engine.HttpClientEngine
import io.ktor.client.engine.darwin.*
actual fun createHttpClientEngine(): HttpClientEngine {
return Darwin.create {
configureRequest {
setAllowsCellularAccess(true)
}
}
}
And in my SupabaseService, in the init I added the client:
lateinit var supabaseClient: SupabaseClient
@OptIn(SupabaseInternal::class)
fun initSupabaseClient(
supabaseUrl: String,
supabaseAnonKey: String
) {
supabaseClient = createSupabaseClient(
supabaseUrl = supabaseUrl,
supabaseKey = supabaseAnonKey,
) {
install(Postgrest)
install(Auth)
httpEngine = createHttpClientEngine()
}
}
I hope it can be helpful for someone else too. :)
