Swift - json nested array not returning value - arrays

Question

I am trying to grab the array from "imports" from the JSON file but the array is returning encoded.
[ServerName.JSONNodeValue, ServerName.JSONNodeValue, ServerName.JSONNodeValue, ServerName.JSONNodeValue, ServerName.JSONNodeValue, ServerName.JSONNodeValue]
I know the data can be seen as if I print the value of the data in the JSONNode file, it comes up as
https://servername.com/storage/sessions/00167/imports
(
"movie1.mov",
"movie3.mov",
"movie2.mov",
"._movie1.mov",
"._movie2.mov",
"._movie3.mov"
)
This isn't my code and the reason why I am struggling as I am still pretty new at swift.
My JSON file looks similar to this.
{
"id": 135
"name": Test
"angles" [
{
"id": 35,
"name": "test",
"mp4": "http:/0.0.0:3000/storage/seesion/00138/url.mp4"
}
]
"imports" [
movie1.mp4,
movie2.mp4,
movie3.mp4
]
}
Swift Code - Session File
struct Session {
var id: Int
var name: String
var angles: [Angle] = []
var imports: [Any]
extension Session {
init(fromDict dict: [String: AnyObject]){
let node = JSONNodeValue(dict)
let sessionId = node["id"].int ?? 0
self.id = sessionId
self.name = node["name"].string ?? "???"
print(name)
self.imports = node["imports"].arrayOrEmpty
self.angles = node["angles"].arrayOrEmpty.map { angleDict in
Angle(fromDict: angleDict.object!)
}
JSONnode file that handles the JSON
protocol JSONNode {
subscript(key: String) -> JSONNode { get }
var int: Int? { get }
var double: Double? { get }
var string: String? { get }
var bool: Bool? { get }
var date: Date? { get }
var array: [JSONNode]? { get }
var arrayOrEmpty: [JSONNode] { get }
var object: [String: Any]? { get }
var objectOrEmpty: [String: Any] { get }
}
class JSONNodeValue : JSONNode {
static func parse (_ data: Data) -> JSONNode {
if let root = try? JSONSerialization.jsonObject(with: data) {
return JSONNodeValue(root)
} else {
return JSONNodeNone.instance
}
}
var value: Any
init(_ value: Any) {
self.value = value
print(value) // SHOWS THE DATA I NEED
}
subscript(key: String) -> JSONNode {
if let object = value as? [String: Any], let subvalue = object[key] {
return JSONNodeValue(subvalue)
} else {
return JSONNodeNone.instance
}
}
var int: Int? {
return value as? Int
}
var double: Double? {
return value as? Double
}
var string: String? {
return value as? String
}
var bool: Bool? {
return value as? Bool
}
var date: Date? {
if let formatted = string {
return Date.fromIso8601(formatted)
} else {
return nil
}
}
var array: [JSONNode]? {
if let array = value as? [Any] {
return array.map { JSONNodeValue($0) }
} else {
return nil
}
}
var arrayOrEmpty: [JSONNode] {
return array ?? []
}
var object: [String: Any]? {
return value as? [String: Any]
}
var objectOrEmpty: [String : Any] {
return object ?? [:]
}
}
Could someone point me in the right direction or to other answered questions that could help me solve this? Thanks

Answer 1

The struct looks good, but remove the = [] after [Angle], but you should use Codable protocol to parse the JSON like so:
struct Session: Codable {
var id: Int
var name: String
var angles: [Angle]
var imports_dir_contents: [Any]
then create another struct to get the Angle
struct Angle: Codable
let id: Int
let name: String
let mp4: String
Then you want to parse using the Codable protocol method by passing in the data retrieved from the networking call.
do {
let newJSONDecoder = JSONDecoder()
let session = try newJSONDecoder.decode(Session.self, from:data)
let anglesArray = session.angles // or use whatever array property you want
} catch {
print("error while parsing:\(error)")
}

I solved what I was trying to achieve by adding a new a variable in the JSNODE file which then gave me ["movie1.mov", "movie3.mov", "movie2.mov", "._movie1.mov", "._movie2.mov", "._movie3.mov"]
var arrayList: [String]? {
return value as? [String]
}
Thanks for the help though.
