How to parse any stringified array such as "[\"Bob\", \"Tim\", \"Tina\"]" in Swift? It should return a JSON array such as ["Bob", "Tim", "Tina"].
Sorry if this is a duplicate question, but I could not find any answer for a generic stringified array where the structure of the array elements are not known.
Try doing it like this, Works for me every time:
let jsonText = "[\"Bob\", \"Tim\", \"Tina\"]"
var array: [String]?
if let data = jsonText.data(using: String.Encoding.utf8) {
do {
array = try JSONSerialization.jsonObject(with: data, options: []) as? [String]
if let myArray = array {
print(myArray)
}
} catch let error as NSError {
print(error)
}
}
It prints : ["Bob", "Tim", "Tina"]
Hope it helps!!
extension String
{
func decodeUrl() -> String
{
return self.removingPercentEncoding!
}
}
extension Data
{
func dataToJSON() -> Any? {
do {
return try JSONSerialization.jsonObject(with: self, options: [])
} catch let myJSONError {
print(myJSONError)
}
return nil
}
}
Usage :
if let data = your_stringified_array.decodeUrl().data(using: String.Encoding.utf8) {
if let jsonc = data.dataToJSON() {
print(jsonc)
}
}
Result is in AnyObject.
