Storing JSON Dictionary Values into Variables - php

Question

Using a PHP file, I echoed data from a MySQL database in the following format: [{"longitude":"-122.031","latitude":"37.3323”}]
In my Swift file, I use NSJSONSerialization.JSONObjectWithData() to create a JSON dictionary that looks like the following
(
{
latitude = "37.3323";
longitude = "-122.031";
}
)
If I wanted to store the individual dictionary values inside variables, I believe the following snippet of Swift code would work
class Location: NSObject {
var latitude: String?
var longitude: String?
}
var locations = [Location]()
if let locationDictionary = jsonDictionary["coordinates"] as? [String: AnyObject] {
let location = Location()
location.setValuesForKeysWithDictionary(locationDictionary)
print(location.latitude, location.longitude)
}
The only problem I’m having is that I need my JSON dictionary to look like
(
coordinates = {
latitude = "37.3323";
longitude = "-122.031";
}
)
but I don’t know what steps to take to achieve this.

You would have to make your JSON like this:
[{"coordinates":{"longitude":"-122.031","latitude":"37.3323"}}]
which is an array of dictionaries, where each dictionary contains another one.
And here is your code adapted for the new format:
if let json = try? NSJSONSerialization.JSONObjectWithData(data, options: []), // your source may differ, I'm just using this line for my example
content = json as? [[String:AnyObject]] { // the array of dictionaries
for item in content {
if let locationDictionary = item["coordinates"] as? [String: AnyObject] { // the dictionary inside the dictionary
let location = Location()
location.setValuesForKeysWithDictionary(locationDictionary)
print(location.latitude, location.longitude)
}
}
}
