I am very new to JSON parsing and tried to parse a JSON file which has list of cars but when I do parse, it gives out nil:
func jsonTwo(){
let url = Bundle.main.url(forResource: "car_list", withExtension: "json")!
let data = try! Data(contentsOf: url)
let JSON = try! JSONSerialization.jsonObject(with: data, options: []) as? [String : Any]
print(".........." , JSON , ".......")
let brand = JSON?["models"] as? [[String : Any]]
print("=======",brand,"=======")
}
and when I made some modifications to this code as below:
func jsonTwo(){
let url = Bundle.main.url(forResource: "car_list", withExtension: "json")!
let data = try! Data(contentsOf: url)
let JSON = try! JSONSerialization.jsonObject(with: data, options: [])
print(".........." , JSON , ".......")
let brand = JSON["brand"] as? [[String : Any]]
print("=======",brand,"=======")
}
then I get and error saying:
"Type 'Any' has no subscript members"
below is a sample of the JSON file that I am using
[{"brand": "Aston Martin", "models": ["DB11","Rapide","Vanquish","Vantage"]}]
Please note that variable JSON
in your code is an array of objects.
You have to cast it properly.
func jsonTwo(){
let url = Bundle.main.url(forResource: "car_list", withExtension: "json")!
let data = try! Data(contentsOf: url)
let JSON = try! JSONSerialization.jsonObject(with: data, options: [])
print(".........." , JSON , ".......")
if let jsonArray = JSON as? [[String: Any]] {
for item in jsonArray {
let brand = item["brand"] as? String ?? "No Brand" //A default value
print("=======",brand,"=======")
}
}
}
