Handling Errors Code Challenge

Hello community,

Stuck on this challenge. Point me in the right direction if possible. Otherwise, a solution to study works great too.

Thanks in advance :)

enum ParserError: Error {
  case emptyDictionary
  case invalidKey

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

  func parse() throws {
     guard let value = data?["someValue"] else {
            throw ParserError.emptyDictionary
        guard let key = data?["someKey"] else {
            throw ParserError.invalidKey

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