5,225 PointsNot sure why this isn't passing?
I'm getting the error: "If the key does not exist, make sure to throw the InvalidKey error." I'm pretty sure I've done that so I'm not sure what's wrong.
enum ParserError: Error {
case emptyDictionary
case invalidKey
}
struct Parser {
var data: [String : String?]?
func parse() throws {
guard (data?.keys.contains("someKey")) != nil else {
throw ParserError.invalidKey
}
guard (data?["someKey"]) != nil else {
throw ParserError.emptyDictionary
}
}
}
let data: [String : String?]? = ["someKey": nil]
let parser = Parser(data: data)

guard (data?.keys.contains("someKey")) == nil else {
Curious stuff, but hope this helps in the meanwhile!
