So I'm trying to parse my local data but it's throwing the error and I could not figure it out; I couldn't retrieve any Data and the Data is a bit too complex to figure out on its own.
if(UserDefaults.standard.string(forKey: "UID") != nil){
guard let dataFile = Bundle.main.path(forResource: "database7", ofType: "json"),
let database = FileManager.default.contents(atPath: dataFile) else {
fatalError("Data not found")
}
let json = try? JSONSerialization.jsonObject(with: database, options: [])
if let json = json as? [String: Any] {
if let jsonChild = json["tired"] as? [[String: Any]] {
for botanical in jsonChild {
var botanicalObject = BotanicModel(json: botanical)
botanicDetail.append(botanicalObject)
print(botanicDetail)
}
}
} else{
fatalError("Failed to parse json")
}
}
Below is the Model
struct BotanicModel {
var id: ID
init(id: ID ){
self.id = id
}
init(json: [String:Any]){
self.id = ID(json: json["id"] as? [String:Any] ?? [:])
}
}
struct ID {
var name: String
var therapeutic: [String]
var clinical: [String]
var contraindications: [String]
var drugNutrient: [String]
var chemical: [String]
var toxicity: [String]
init(name: String, therapeutic: [String], clinical: [String], contraindications: [String], drugNutrient: [String], chemical: [String], toxicity: [String]) {
self.name = name
self.therapeutic = therapeutic
self.clinical = clinical
self.contraindications = contraindications
self.drugNutrient = drugNutrient
self.chemical = chemical
self.toxicity = toxicity
}
init(json: [String: Any]) {
self.name = json["name"] as? String ?? "name"
self.therapeutic = json["therapeutic"] as? [String] ?? []
self.clinical = json["clinical"] as? [String] ?? []
self.contraindications = json["contraindications"] as? [String] ?? []
self.drugNutrient = json["drugNutrient"] as? [String] ?? []
self.chemical = json["chemical"] as? [String] ?? []
self.toxicity = json["toxicity"] as? [String] ?? []
}
}

Your model structure is quite rigid because the top object is named "tired", which forces one variable to be named like that. Your JSON should actually be different if you are looking for different types of symptoms - for example, having "symptom : tired," on the top, followed by "herbs : [ { id:...".
Your JSON can be decoded using the following objects:
struct Tired: Codable {
let tired: [HerbCollection]
}
struct HerbCollection: Codable {
let id: [Herb]
}
struct Herb: Codable {
let name: String
let therapeutic: [String]
let clinical: [String]
let contraindications: [String]
let drugNutrient: [String]
let chemical: [String]
let toxicity: [String]
}
Here's how to decode:
do {
let tired = try JSONDecoder().decode(Tired.self, from: Data(json.utf8))
print(tired.tired[0].id[0].name)
print(tired.tired[0].id[0].therapeutic[0])
print(tired.tired[0].id[0].clinical[0])
// etc.
} catch {
print(error)
}
