Crash on reconnect

[psi-gh]

I have such crash. It occurring in ~1 minute after running app if I specify reconnect: true in gql.initServer(connectionParams: nil, reconnect: true)
If I set reconnect to false, there won't be crash, but subscription will stop in 1 minute without any notice.

Hey!

Thank you for reporting this, I'm gonna check and add some unit tests for the future!

Hi, have the same issue - app crashes after few minutes, reason - 'Cannot call -(void)open on SRWebSocket more than once'

[psi-gh]

@aparandiy Seems like this repo not supporting. You can look at Apollo project.

[aparandiy]

if I am listening for subscriptions from one controller - all works perfect, but if i connect subscriptions more than one controller - it works, but after few minutes of using the app crashes with reason - Cannot call -(void)open on SRWebSocket more than once

Ok I see where is the bug, I need to rush and push two solutions:

• The fix of this one, it looks be okay to fix and to think a new architecture
• Add heartbeat to avoid disconnect
