Getting All the values of this output json - json

Question

I want to extract the names of these coffes this is an extract of my output because i have like 1000 names, and i want to take them all automatically :
results = (
{
geometry = {
location = {
lat = "-33.3979227";
lng = "-70.58503859999999";
};
viewport = {
northeast = {
lat = "-33.39783990000001";
lng = "-70.58502229999999";
};
southwest = {
lat = "-33.39795669999999";
lng = "-70.58507830000001";
};
};
};
id = 46354da06de96a36c5c44a5fa05a10f8f83f8edd;
name = "Hotel Bidasoa";
"opening_hours" = {
"open_now" = 1;
"weekday_text" = (
);
};
}
);
"place_id" = ChIJ4dfUCC7PYpYRRDkSNifrfBE;
rating = "4.7";
scope = GOOGLE;
types = (
cafe,
lodging,
food,
store,
"point_of_interest",
establishment
);
vicinity = "Avenida Vitacura 4873, Santiago, Santiago";
},
{
geometry = {
location = {
lat = "-33.37900460000001";
lng = "-70.55533029999999";
};
viewport = {
northeast = {
lat = "-33.37897230000002";
lng = "-70.5553148";
};
southwest = {
lat = "-33.37910149999999";
lng = "-70.55537679999999";
};
};
};
id = c451d2146b7a065fa1afd0ffa39353a4b1cae178;
name = "Ceibo Emporio Cafeter\U00eda";
"opening_hours" = {
"open_now" = 0;
"weekday_text" = (
);
};
and thi is my code, but only prints me the first name i want both because i have like 1000 names:
let jsonResult = try JSONSerialization.jsonObject(with: urlContent, options: JSONSerialization.ReadingOptions.mutableContainers) as AnyObject
print (jsonResult)
if let nombre = ((jsonResult["results"]as?NSArray)?[0]as?NSDictionary)?["name"] {
print (nombre)
}

As always:
Never use NSDictionary / NSArray in Swift when parsing JSON.
Never use mutableContainers in Swift. It's completely useless.
To get all items in the results array use a loop, for convenience and readability use a type alias:
typealias JSONDictionary = [String:Any]
if let jsonResult = try JSONSerialization.jsonObject(with: urlContent, options: []) as? JSONDictionary {
print (jsonResult)
if let results = jsonResult["results"] as? [JSONDictionary] {
for result in results {
print(result["name"] as? String ?? "n/a")
if let geometry = result["geometry"] as? JSONDictionary,
let location = geometry["location"] as? JSONDictionary {
let lat = location["lat"] as? Double ?? 0.0
let lng = location["lng"] as? Double ?? 0.0
print("latitude: \(lat)")
print("longitude: \(lng)")
}
}
}
}
