I am implementing AFNetworking with CocoaPods into a Swift project. I am used to programming in Ruby and I am very new to iOS development. Cocoapods was tricky to get working properly in my project but I can now successfully access the AFNetworking library.

What I am trying to do is hit a form with a POST and get a response as "text/html" that I can parse so that I can tell if it saves. This is not an API per se, but a form generated by InfusionSoft. A user will enter an email address and I will send that off to an API for storage. Here is the code I am using: 

```
let manager = AFHTTPRequestOperationManager()
            var parameters = ["inf_form_xid": "MY_ACCESS_ID",
                      "inf_form_name": "Webform in Content App",
                      "infusionsoft_version": "1.34.0.35",
                      "inf_field_email": self.emailTextField.text]

    manager.POST( "https://ns166.infusionsoft.com/app/form/process/REALLYLONGUNIQUEID",
    parameters: parameters,
    success: { (operation: AFHTTPRequestOperation!,responseObject: AnyObject!) in
        println("JSON: " + responseObject.description)
    },
    failure: { (operation: AFHTTPRequestOperation!,error: NSError!) in
        println("Error: " + error.localizedDescription)
    })

```

And the error that I am receiving this as a response from AFNetworking:

```
Error: Request failed: unacceptable content-type: text/html

```

At the end of the day, I want to verify that it was saved by the server before I allow the user to continue in the application. 

Any help is greatly appreciated.
