I'm utilizing SwiftyJSON.
This is an example of a json string:
{
"geocoded_waypoints" : [
{
"geocoder_status" : "OK",
"place_id" : "ChIJkcemZ9r9jT8RCoy7cipVk3Q",
"types" : [ "route" ]
},
{
"geocoder_status" : "OK",
"place_id" : "ChIJzYyVGtcFjj8RMoV0IaoNhzA",
"types" : [ "route" ]
}
],
"routes" : [
{
"bounds" : {
"northeast" : {
"lat" : 35.7884236,
"lng" : 51.43490389999999
},
"southwest" : {
"lat" : 35.7056256,
"lng" : 51.3073962
}
},
"copyrights" : "Map data ©2017 Google",
"legs" : [
{
"distance" : {
"text" : "20.9 km",
"value" : 20893
},
"duration" : {
"text" : "32 mins",
"value" : 1936
},
"end_address" : "Tehran Province, Tehran, Hossein, Iran",
"end_location" : {
"lat" : 35.7883586,
"lng" : 51.43490389999999
},
"start_address" : "Tehran Province, Tehran, Kooy-e-Bimeh, Rostam, Iran",
"start_location" : {
"lat" : 35.7056307,
"lng" : 51.3167437
},
"steps" : [
{
"distance" : {
"text" : "59 m",
"value" : 59
},
"duration" : {
"text" : "1 min",
"value" : 21
},
"end_location" : {
"lat" : 35.70562779999999,
"lng" : 51.31739839999999
},
"html_instructions" : "Head \u003cb\u003eeast\u003c/b\u003e on \u003cb\u003eRostam\u...
......
print("--->\(json["routes"]["legs"]["distance"]["text"].string)")
}
The desired output is
routes->legs->distance->textCodes used:
let json = NSString(data: data, encoding: String.Encoding.utf8.rawValue) as! String
if let data = json.data(using: String.Encoding.utf8) {
let json = JSON(data: data)
print("--->\(json["routes"]["legs"]["distance"]["text"].string)")
}
print returns --->nil.
