Please assist me what steps I should take and what to change the catch statements to
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]
do {
let parser = Parser(data: data)
try parser.parse()
} catch ParserError.emptyDictionary {
} catch ParserError.invalidKey {
}

For future reference, it's frowned upon in the Community to post code that can be copied and pasted and just work without any explanation of why it works and why it's the correct answer. As such, I've redacted your code here. If you'd like, feel free to re-post your solution, but be sure to give a thorough explanation of why it works and why it's the correct answer. Thanks for helping out in the Community!
