Does it work with SwiftR.useWKWebView = false?

If so, make sure you have CORS enabled on your server. CORS is required for WKWebView to work with SwiftR.

@tejasverixo Please answer same questions RE: wkWebView = false, and whether or not CORS is enabled on your SignalR server.

Thanks for quick reply. But i got solution.

By default SwiftR.useWKWebView = false - It's working fine.
but as per the example if its "True" - It's Not working.

//As per the "Master" branch update i m getting following error

//Code
connection = SignalR("http://swiftr.azurewebsites.net")

//Error
"Cannot invoke initializer for type 'SignalR' with an argument list of type '(String)'"

Note: I did Installation using Pod

@tejasverixo I posted this on SO, but will paste here too:

The pod (swift3), the swift23 branch, and the master branch (API changes) are all different code. You'll need to pick one version of the library and stick with it. If WKWebView = false works, but true doesn't, that means you probably don't have CORS enabled on your SignalR server.

CORS is most likely the culprit here.
