Not sure, what to do here, I'm not sure how to use the keys property and contains method?

error.swift 
enum ParserError: ErrorType {
  case EmptyDictionary
  case InvalidKey
}

struct Parser {
  var data: [String : String?]?

  func parse() throws {

  }
}

let data: [String : String?]? = ["someKey": nil]
let parser = Parser(data: data)

Hey Carl Smith,

I wrote this a long time ago. https://teamtreehouse.com/community/error-handling-2

It seemed to have helped a few people. I cringe while re-reading it but possible it will help you.

If you still have questions let me know, Good Luck

Thank you sooo much for that, I was really struggling with that first part. The link was not a bad read at all, thank you so much for all that.
