SOLVED: The data couldn't exist read because it isn't in the right format.

	@iam-that-1 Apr '21 this is the API { "ip":"", "hostname":"", "continent_code":"", "continent_name":"", "country_code2":"", "country_code3":"", "country_name":" ", "country_capital":"", "state_prov":"", "district":"", "city":"", "zipcode":"", "latitude":00.00, "longitude":00.00, "is_eu":"false", "calling_code":"+", "country_tld":"", "languages":"", "country_flag":"https", "internet service provider":"", "connection_type":"", "organization":"", "asn":"", "geoname_id":0000, "currency":{ "name":"", "code":"", "symbol":"" }, "time_zone":{ "proper noun":"", "offset":3, "current_time":"", "current_time_unix":"", "is_dst":"", "dst_savings":0 } } and this is structs struct Location: Codable { allow ip, hostname, continentCode, continentName: String? let countryCode2, countryCode3, countryName, countryCapital: String? let stateProv, district, city, zipcode: String? let latitude, longitude: Double? permit isEu, callingCode, countryTLD, languages: String? let countryFlag: Cord? let internet access provider, connectionType, organization, asn: String? let geonameID: Int? let currency: Currency? allow timeZone: TimeZone? enum CodingKeys: String, CodingKey { case ip, hostname case continentCode case continentName case countryCode2 case countryCode3 case countryName case countryCapital example stateProv instance commune, urban center, zipcode, breadth, longitude case isEu case callingCode case countryTLD instance languages example countryFlag case isp case connectionType case organisation, asn case geonameID example currency case timeZone } } struct Currency: Codable { let name, code, symbol: String? } struct TimeZone: Codable { permit name: String? let offset: Int? let currentTime, currentTimeUnix, isDst: String? let dstSavings: Int? enum CodingKeys: String, CodingKey { instance name, offset case currentTime case currentTimeUnix case isDst example dstSavings } } just I got this error. (The data couldn't be read because it isn't in the correct format.). I built the structs from a script 1
	@roosterboy HWS+ Apr '21 Is that the actual JSON yous are testing with or did y'all give united states an altered version? Because information technology'due south not valid JSON due to these lines: `"latitude":00.00, "longitude":00.00, "geoname_id":0000,` They should be: `"latitude":0.0, "longitude":0.0, "geoname_id":0,` i
	@iam-that-one Apr '21 yea it is altered, becuase the response contains my information. just I want to know if the structs stand for the json structure or not, and how to do it. The actual JSON is valid and contains an actual breadth and longitude. asking function: func fetch_location(API_KEY : Cord, ip : String){ let API_URL = "https://api.ipgeolocation.io/ipgeo?apiKey=\(API_KEY)&ip=\(ip)" baby-sit allow url = URL(string: API_URL)else{ print("invalid url ...") return } let decoder = JSONDecoder() permit request = URLRequest(url: url) URLSession.shared.dataTask(with: asking) { (data, response, error) in if error != nil{ print("fault i") impress(error?.localizedDescription equally Whatever) } else{ if let data = data{ do{ let result = effort decoder.decode(Location.cocky, from: data) impress(effect ) }catch{ print("errpr 2") print(mistake.localizedDescription) } } } }.resume() } 1
	@roosterboy HWS+ Apr '21 just I want to know if the structs represent the json structure or not Aye. Once I corrected the zeroes event, your `struct`southward worked fine to decode the example JSON. A tip... When decoding JSON, don't do this: `impress(error.localizedDescription)` Do this instead: `print(fault)` Information technology will give you much more than particular about what the problem is. This: `The data couldn't be read because it isn't in the right format.` versus this: `dataCorrupted(Swift.DecodingError.Context(codingPath: [], debugDescription: "The given data was non valid JSON.", underlyingError: Optional(Error Domain=NSCocoaErrorDomain Lawmaking=3840 "Number with leading zero effectually character 482."` i
	@iam-that-ane Apr '21 I got the problem when I print(error), I inverse latitude, longitude to be String instade of Double, thankyou. ane
	@iam-that-one Apr '21 I am sorry. just why some properties contains zero inside. The API has a value. 1
	@roosterboy HWS+ Apr '21 Okay, after hunting down some sample API information—which you actually should supply with these types of questions, as your `struct`s worked fine with the sample information you did provide but fail with actual sample data from the API documentation—y'all can brand these changes and it should piece of work: struct Location: Codable { let ip, hostname, continentCode, continentName: String? let countryCode2, countryCode3, countryName, countryCapital: String? let stateProv, district, city, zipcode: String? let breadth, longitude: String? //instead of Double? let isEu: Bool? //instead of String? permit callingCode, countryTld, languages: String? //countryTld instead of countryTLD let countryFlag: String? let isp, connectionType, organization, asn: Cord? let geonameId: Cord? //instead of permit geonameID: Int? let currency: Currency? allow timeZone: TimeZone? enum CodingKeys: String, CodingKey { case ip, hostname example continentCode case continentName case countryCode2 case countryCode3 case countryName case countryCapital case stateProv instance district, urban center, zipcode, breadth, longitude case isEu instance callingCode case countryTld //instead of countryTLD case languages example countryFlag instance isp example connectionType case organization, asn case geonameId //instead of geonameID case currency instance timeZone } } //no changes to Currency struct struct TimeZone: Codable { allow name: String? permit offset: Int? allow currentTime: String? let currentTimeUnix: Appointment? //instead of Cord? let isDst: Bool? //instead of Cord? allow dstSavings: Int? enum CodingKeys: Cord, CodingKey { case name, start case currentTime case currentTimeUnix example isDst case dstSavings } } And and then when yous create your `JSONDecoder`, be sure to ready its `keyDecodingStrategy` to `.convertFromSnakeCase`. OR, you can add explicit key mappings to your `CodingKeys` `enum`s, like this: `example continentCode = "continent_code" example continentName = "continent_name" //...etc..` Note that doing it this mode would allow you lot to keep `countryTLD` and `geonameID` in your `Location` `struct`. `case countryTLD = "country_tld" example geonameID = "geoname_id"` 1
	@iam-that-i April '21 Thank you, it was my mistake, I merely took sampel of resopnses that is non workes in my case, or non represents the bodily response from API. 1
