Logical Operators in PFQuery Error

Question

I am trying to use an AND operand in a PFQuery but I get the following error at query.whereKey... Is there a way to achieve this?

No '&&' candidates produce the expected contextual result type 'AnyObject'

let bagNumber = defaults.objectForKey("bagNumber") as! String
query.whereKey("bagNumber", equalTo: "0" && bagNumber)

Hi it looks like you are trying to concatenate "0" and the "bagNumber" to have something like "0123", in this case youe should write query.whereKey("bagNumber", equalTo: "0" + bagNumber)

But if not how can a number be equal to 0 AND equal to another number?
