Basically, what I want to do is print a full json object that has a number of arrays inside it. For the sake of simplicity, I'll just paste two of the structs below:
struct Incomes : Codable {
var *****_monthly_amount: Int = 0
var countable_group: String = ""
var year: String = ""
enum CodingKeys: String, CodingKey {
case *****_monthly_amount
case countable_group
case year
}
}
struct Person_details : Codable {
enum CodingKeys: CodingKey {
case age
case work_status, marital_status
case pregnant, disabled, attending_school, minimum_employment_over_extended_period
}
var age: Int = 18
var minimum_employment_over_extended_period: Bool = false
var work_status: String = ""
var pregnant: Bool = false
var attending_school: Bool = false
var disabled: Bool = false
var marital_status: String = ""
}
These two are connected to a struct: Household :
struct Household : Codable {
var receiving_benefits : [String] = []
var energy_crisis : Bool = false
var utility_providers: [String] = [""]
var person_details: [Person_details] = []
var Income: [Incomes] = []
enum CodingKeys: String, CodingKey {
case receiving_benefits = "receiving_benefits"
case energy_crisis = "energy_crisis"
case utility_providers = "utility_providers"
case person_details = "person_details"
case Income = "incomes"
}
}
Finally, a class that connects it all:
class Json4Swift_Base : ObservableObject, Codable {
@Published var household = Household()
enum CodingKeys: String, CodingKey {
case household = "household"
}
init() { }
func encode(to encoder: Encoder) throws {
var container = encoder.container(keyedBy: CodingKeys.self)
try container.encode(household, forKey: .household)
}
required init(from decoder: Decoder) throws {
let container = try decoder.container(keyedBy: CodingKeys.self)
household = try container.decode(Household.self, forKey: .household)
}
}
Followed by a @StateObject & @State's:
@StateObject var Base = Json4Swift_Base()
@State var user = Household()
@State var personDetails = Person_details()
@State var Income1 = Incomes()
When a button is selected, I have this to print out the json in the console:
let encoder = JSONEncoder()
encoder.outputFormatting = .prettyPrinted
do {
let data = try encoder.encode(Base)
if let str = String(data: data, encoding: .utf8) {
print("\(str)\n")
}
} catch {
print("---> error: \(error)")
}
It prints this with Empty arrays:
{
"household" : {
"assets" : [
],
"person_details" : [
],
"utility_providers" : [
""
],
"incomes" : [
],
"receiving_benefits" : [
],
"region" : "PA",
"residence_type" : "rent",
"received_maximum_benefit" : {
"cip" : false
},
"at_risk_of_homelessness" : false,
"property_tax_past_due" : false
}
}
When I print personDetails by itself and not Base, I get the person_details, but why can't I get person_details (or Income) when Base is printed (Since it's all connected) ? Why would it come up as an empty array? I have these values connected to toggles & TextFields but they're not printing. Thanks for any help!
