Parsing local json file on Swift - json

Question

I have a local JSON and try to decode but got "Expected to decode Array but found a dictionary instead" error. The json file and two structs below:
{
"Stanford University": [{
"type": "government",
"name": "Stanford University",
"city": "Santa Clara",
"major": "Computer Engineering"
},
{
"type": "government",
"name": "Stanford University",
"city": "Santa Clara",
"major": "Economics"
}
],
"Berkeley University": [{
"type": "foundation",
"name": "Berkeley University",
"city": "Alameda",
"major": "Communication"
},
{
"type": "foundation",
"name": "Berkeley University",
"city": "Alameda",
"major": "Physics"
}
]
}
two structs:
struct Universite4: Codable {
let name: String?
let major:[Major]?
}
struct Major: Codable {
let type: String?
let name: String?
let major: String? }
And this is code for data load and decode;
public class DataLoader {
#Published var universite4 = [Universite4]()
init() {
load()
}
func load() {
if let unv4json = Bundle.main.url(forResource: "unv4", withExtension: "json") {
do {
let data = try Data(contentsOf: unv4json)
let jsonDecoder = JSONDecoder()
let dataFromJson = try jsonDecoder.decode([Universite4].self, from:data)
self.universite4 = dataFromJson
} catch {
print("Error: \(error)")
}
}
}
}
Does anybody know how can I fix above code? Regards.

Answer 1

Try to change, the issue here is that actually your keys are sort of "Dynamic keys" which I don't recommend but if you have to use them, so try this.
let dataFromJson = try jsonDecoder.decode([Universite4].self, from:data)
to
let dataFromJson = try jsonDecoder.decode([String:[Major]].self, from:data)
