Check if Parse.com field is undefined/nil ?

In parse when you have a field for data, let's say a string, to check if there is no data in it, you have to click on the field to remove the "undefined", then in Xcode do:

if(myString.isEmpty){/*do something*/}

If I try to simply compare it to nil, I get the error: "Binary operator "==" cannot be applied to operands of type string and nil"

I am making an app that retrieves several objects from Parse.com, I want to be able to constantly update my app from there, what I have not been able to figure out is how to add checks for a field that is undefined, sometimes I want to be able to leave some of the data fields undefined because not all of them are crucial, so how would I achieve this?

There is the same question here, but what the user asking used to solve his problem, did not work for me

you can do optional binding 

if let name = employerProfileObject.valueForKey("name"){
      self.companyIndustry.text = "\(name.capitalizedString)"
}

it wont return an error if the field in parse is empty
