I get escape characters from jsonSerialization and cannot decode them in Swift - json

Question

I have a project in swift where I post a URL and get the result in json.
The json reply from the url contains many greek letters and for example instead of "Γ" I get "\U0393".
How I can translate the escape characters in swift?
My code is the following:
let url = NSURL(string: "https://www.something.that.creates.a.json.array")!
let task = URLSession.shared.dataTask(with: url as URL) { (data, response, error) -> Void in
if let urlContent = data {
do {
let jsonResult = try JSONSerialization.jsonObject(with: urlContent, options: JSONSerialization.ReadingOptions.mutableContainers)
print(jsonResult)
} catch {
print("Json Serialization error")
}
}
}
task.resume()

Answer 1

The escape characters where indeed appearing correct as rmaddy wrote.
But I had to cast the result as [[String : Any]] in order to access the Dictionary inside the array correctly.
let url = NSURL(string: "https://www.something.that.creates.a.json.array")!
let task = URLSession.shared.dataTask(with: url as URL) { (data, response, error) -> Void in
if let urlContent = data {
do {
let jsonResult = try JSONSerialization.jsonObject(with: urlContent, options: JSONSerialization.ReadingOptions.mutableContainers) as! [[String : Any]]
print(jsonResult[0]["description"])
} catch {
print("Json Serialization error")
}
}
}
task.resume()
