Crash, Speech example not functional iOS 10 / iPhone 7 - SSL?

[jacobjennings]

I got a crash on run that was fixed by changing this line in Channel.init
underlyingChannel = cgrpc_channel_create_secure(address, (s! as NSString).utf8String, host)

I got things compiled and running, but I'm getting empty response callbacks from receiveMessage in Call.swift

hardware sample rate = 16000.0, using specified rate = 16000

The alt-svc metadata seems to suggest that we're not using port 443?
