The problem is merely that your structs look nothing at all like your JSON!<\/p>\n

Your JSON is a dictionary whose keys have names like \"-8802586561990153106-1804221538-5\"<\/code> and \"8464567322535526441-1804221546-15\"<\/code>. But I don’t see you declaring any struct that deals with those keys.<\/p>\n

Then each of those turns out to be a dictionary with keys like \"zug\"<\/code>, \"ankunft\"<\/code>, and \"abfahrt\"<\/code>. But I don’t see you declaring any struct that deals with those keys either.<\/p>\n

And then the \"zug\"<\/code> has keys \"klasse\"<\/code> and \"nummer\"<\/code>; you don’t have those either.<\/p>\n

And so on.<\/p>\n

Either your structs must look exactly like your JSON, or else you must define CodingKeys and possibly also implement init(from:)<\/code> to deal with any differences between your structs and your JSON. I suspect that the keys \"-8802586561990153106-1804221538-5\"<\/code> and \"8464567322535526441-1804221546-15\"<\/code> are unpredictable, so you will probably have<\/em> to write init(from:)<\/code> in order to deal with them.<\/p>\n

For example, I was able to decode your JSON like this (I do not really recommend using try!<\/code>, but we decoded without error and it’s just a test):<\/p>\n

    struct Entry : Codable {\n        let zug : Zug\n        let ankunft : AnkunftAbfahrt\n        let abfahrt : AnkunftAbfahrt\n    }\n    struct Zug : Codable {\n        let klasse : String\n        let nummer : String\n    }\n    struct AnkunftAbfahrt : Codable {\n        let zeitGeplant : String\n        let zeitAktuell : String\n        let routeGeplant : [String]\n    }\n    struct Top : Decodable {\n        var entries = [String:Entry]()\n        init(from decoder: Decoder) throws {\n            struct CK : CodingKey {\n                var stringValue: String\n                init?(stringValue: String) {\n                    self.stringValue = stringValue\n                }\n                var intValue: Int?\n                init?(intValue: Int) {\n                    return nil\n                }\n            }\n            let con = try! decoder.container(keyedBy: CK.self)\n            for key in con.allKeys {\n                self.entries[key.stringValue] = \n                    try! con.decode(Entry.self, forKey: key)\n            }\n        }\n    }\n    \/\/ d is a Data containing your JSON\n    let result = try! JSONDecoder().decode(Top.self, from: d)\n<\/code><\/pre>\n<\/p><\/div>\n
