Thanks for asking! Could you check if your server is using SSL properly?
If not, you could specify the following option: *options.transport = GRPCDefaultTransportImplList.core_insecure* As in this example below: https://github.com/grpc/grpc/blob/67d6b8ea748433109a6d1c91ea9a8d513bf3e99d/examples/objective-c/helloworld/main.m#L59 Hope that helps!
