JSON decoding error for ping in v0.1.5

[Markus Klepp]

Since version v0.1.5 the ping message fails JSON decoding with:
[ActionCableClient] Error decoding message: Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 0." UserInfo={NSDebugDescription=Invalid value around character 0.}

Also for 0.1.4.

Reverting to 0.1.3 fixed it for me

What version of Rails are you on?

In the last release I removed SwiftyJSON as a dependency. Will investigate.

This could be the issue. My backend guy is using an older version of actioncable. The raw ping message looks like this:
{"identifier":"_ping","message":1466618952}

It looks like the underscore in the identifier has been removed:
old version:
https://github.com/danielrhodes/Swift-ActionCableClient/blob/v0.1.3/Pod/Classes/Constants.swift#L53
new version:
https://github.com/danielrhodes/Swift-ActionCableClient/blob/v0.1.5/Pod/Classes/Constants.swift#L56

Thanks

In RC1 of Rails there is support for versioning of the underlying ActionCable protocol so that these kinds of issues can be avoided more elegantly in the future.

I will need to switch out the underlying WebSocket library to support that though as Starscream does not support it.
