I was working on converting this delegate protocol function from an Objective-C tutorial, but ran into an error trying to access the values in a dictionary by using the subscript to return the value based on the key. I am not quite sure what the error here means. Any help would be greatly appreciated!
// Sent to the delegate to determine whether the sign up request should be submitted to the server
func signUpViewController(signUpController: PFSignUpViewController!, shouldBeginSignUp info: [NSObject : AnyObject]!) -> Bool {
var informationComplete: Bool = true
// Loop through all of the submitted data
for key in info {
var field: String = info[key] // Error occurs at this line on info
if field.isEmpty {
informationComplete = false
break
}
}
// Display an alert if a field was not completed
if !informationComplete {
let alertView: UIAlertView = UIAlertView(title: "Missing Information", message: "Please make sure all information is filled out!", delegate: nil, cancelButtonTitle: "ok")
}
return informationComplete
}

You did not post your declaration. But likely you can solve it with:
for (key, field) in info {
if field.isEmpty {
informationComplete = false
break
}
}
