08/08/2021, 5:13 AMHi, how can I use GraphQL in KMM projects. Because Apollo requires iOS 13+ we’re looking for an alternative.

08/08/2021, 8:10 AMDo you need subscriptions ? iOS 13 is only required for WebSockets. It might work if you don't use subscriptions. Worst case, we could move websockets to a separate module

08/08/2021, 9:10 AMYeah, websocket will be used heavily in the project. Is there any libraries to convert data models to GraphQL queries? If we want to use Ktor instead of Apollo

08/08/2021, 9:25 AMCan Ktor do WebSocket on iOS ? Reading https://ktor.io/docs/websocket-client.html#usage I'm not sure

08/08/2021, 9:42 AMYou’re right, relating to this issue https://github.com/ktorio/ktor/issues/1894 it doesn’t support websocket on iOS. Is there any alternative way?

08/08/2021, 10:06 AMIf you need subscriptions on iOS < 13, you'll have to write your own WebSockets code. Either using plain C sockets or maybe linking with starscream, a WebSocket library on iOS

08/08/2021, 12:12 PMWhy it's not compatible with iOS < 13? According to the apple docs NSURLSession is available on iOS 7.0+
