Question

Did someone get ktor to work on ios For me the get call suspends just forever ``` Test fun test val client = HttpClient runBlocking println start val result String = client get <https www google com > println result=$result ``` I m using ```implementation io ktor ktor client ios 1 5 1 ``` And ```org jetbrains kotlinx kotlinx coroutines core 1 4 2 native mt``` With the `strictly` block applied

Michal Klimczak · Answer

I have used it successfully for some time Never in a runBlocking though but I don t think this should make any difference But of course println will not work on ios not sure if you are really use it or it s just an example

Paul Woitaschek · Answer

No it s no example And println works fine Just that it doesn t print the second statement as it s never reached

louiscad · Answer

I guess it s blocking the main loop that is relied on for the callbacks under the hood Try in real application code in `Dispatchers Main` without `runBlocking` I think it ll work

Paul Woitaschek · Answer

How would I be able to run this in a test then

louiscad · Answer

I m not sure but I d just try to begin with

Michal Klimczak · Answer

Ok I only just noticed that it s a test

Paul Woitaschek · Answer

Apparently there is a `io ktor ktor test dispatcher 1 5 1` artifact exposing a `testSuspend` function which makes this work slightly smiling face

I would guess that nsurlconnection verifies the certificate of the server against a list of authorities it knows Since you are not running this on ios how are kotlin ios tests run anyway it has no certs to verify You could probably use a trust all client and provide it to ktor or provide your own certs to the client What s the purpose of this test

gt how are kotlin ios tests run anyway Thats the question I m asking myself too

Michal Klimczak · Answer

If its just for experimenting I would try pinning th Google cert this will probably help <https levelup gitconnected com kotlin multiplatform ios certificate pinning fd1abba5ca8f|https levelup gitconnected com kotlin multiplatform ios certificate pinning fd1abba5ca8f>
