I have been working on this for awhile and I'm still confused
enum ParserError: Error {
case emptyDictionary
case invalidKey
}
struct Parser {
var data: [String : String?]?
func parse() throws {
}
}
let data: [String : String?]? = ["someKey": nil]
let parser = Parser(data: data)

enum ParserError: Error {
case emptyDictionary
case invalidKey
}
struct Parser {
var data: [String : String?]?
func parse() throws {
guard let data = data else {
throw ParserError.emptyDictionary
}
guard data["someKey"] != nil else {
throw ParserError.invalidKey
}
}
}
let data: [String : String?]? = ["someKey": nil]
let parser = Parser(data: data)
do {
try parser.parse()
} catch ParserError.emptyDictionary {
print("Error: EmptyDictionary")
} catch ParserError.invalidKey {
print("Error: InvalidKey")
}
If this works, please mark it as best answer
