Swift IOS Reading JSON from url - ios

Question

On the below method, I can get the place value but not the location value. how can I get the location?
Thank you in advance!!
func searchDB(looking: String){
var urlString:String = "URLGOESHERE?q=\(looking)"
let url = NSURL(string: urlString)
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithURL(url!, completionHandler: { (data, response, error) -> Void in
if error != nil {
println(error)
}
else {
//processing data
if let arr = NSJSONSerialization.JSONObjectWithData(data, options: nil, error: nil) as? [AnyObject] {
for currPlace in arr {
println(currPlace["name"])
println(currPlace["location"])
}
}
else {
errorOccurred = true
}
}//eo potential data
})
task.resume()
}//eom
This is the result output I am getting:
Optional(Buddha-Bar)
Optional(nil)

Answer 1

Adding a little formatting to the pertinent part of the data:
sample data: {
"formatted_address": "8-12 Rue Boissy d'Anglas, 75008 Paris, France",
"geometry": {
"location": {
"lat": 48.868194,
"lng": 2.321596
}
},
"icon": "http://maps.gstatic.com/mapfiles/place_api/icons/bar-71.png",
"id": "560dd225114fd10997f75ee777bad84bcb40c529",
"name": "Buddha-Bar",
It is unclear what "sample data:" means as it is not quoted, it may be something added by the print statement (my guess) in which case it is not needed to access the components.
The name would be addresses as:
["name"]
The location is in lat/lon so there will be two accesses:
["geometry"]["location"]["lat"]
["geometry"]["location"]["lon"]
In the above the applicable language syntax must be applied, in Swift there will be some pain.
See json.org for information on JSON.

After some frustration and game of thrones. the messy solution was the one below.
an alternative may be api like
https://github.com/lingoer/SwiftyJSON
func searchDB(looking: String){
var errorOccurred:Bool = false
var urlString:String = "URLGOESHERE?q=\(looking)"
let url = NSURL(string: urlString)
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithURL(url!, completionHandler: { (data, response, error) -> Void in
if error != nil {
println(error)
errorOccurred = true
} else {
// println(response) //response from post
//processing data
let jsonObject : AnyObject! = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil)
if let statusesArray = jsonObject as? NSArray{
println("********* LEVEL 1 *******")
println(statusesArray[0])
if let aStatus = statusesArray[0] as? NSDictionary{
println("********* LEVEL 2 *******")
println(aStatus)
if let geometry = aStatus["geometry"] as? NSDictionary{
println("********* LEVEL 3 *******")
println(geometry)
if let currLocation = geometry["location"] as? NSDictionary{
println("********* LEVEL 4 *******")
println(currLocation)
println(currLocation["lat"])
println(currLocation["lng"])
}
}
}
}
else {
errorOccurred = true
}
}//eo potential data
})
task.resume()
}//eom
