Managing encapsulated data in closure - ios

Question

Newbie here.Using Google API Nearby Search. I have problem sending encapsulated data into closure, already populated table with vicinity info, but when i try to send placeID info into closure to get Details, it gives me nil.
Here i get placeID and vicinity, and afterwards populate tableView with places array. Class Place is in separate swift file, function downloadPlaceID is inside ViewController.
class Place {
var placeId: String!
var vicinity: String!
var _placeId: String {
if placeId == nil {
placeId = ""
}
return placeId
}
var _vicinity: String {
if vicinity == nil {
vicinity = ""
}
return vicinity
}
init( place: [String:Any]) {
if let ids = place["id"] as? String {
self.placeId = ids
}
if let vicinities = place["vicinity"] as? String {
self.vicinity = vicinities
}
}
}
func downloadPlaceID (completed: #escaping DownloadComplete) {
let placeURL = URL(string: nearbyURL)
Alamofire.request(placeURL!).responseJSON { (response) in
let result = response.result
if let dictionary = result.value as? [String:Any] {
if let results = dictionary["results"] as? [[String:Any]] {
if let status = dictionary["status"] as? String {
if status == "OK" {
for obj in results {
place = Place(place: obj)
// here i get all the placeID's
places.append(place)
}
}
}
}
}
completed()
}
}
Then i try to get details, into which I put placeID:
func downloadDetails( input: String, completed: DownloadComplete) {
let details = "\(detailsBaseURL)\(detailsPlaceId)\(input)\(detailsKey)\(detailsSearchAPIKey)"
print(placeID)
Alamofire.request(details).responseJSON { response in
let result = response.result
if let dictionary = result.value as? [String:Any] {
if let result = dictionary["result"] as? [String:Any] {
if let phoneNumber = result["formatted_phone_number"] as? String {
self.phone = phoneNumber
print(self.phone!)
}
if let geometry = result["geometry"] as? [String:Any] {
if let location = geometry["location"] as? [String:Any] {
if let latitude = location["lat"] as? Double {
self.lat = latitude
print(self.lat!)
}
if let longitude = location["lng"] as? Double {
self.lng = longitude
print(self.lng!)
}
}
}
if let openingHours = result["opening_hours"] as? [String:Any] {
if let openNow = openingHours["open_now"] as? Bool {
self.workHours = openNow
print(self.workHours!)
}
}
}
}
}
}
Here is code inside viewDidLoad that i'm trying to use to get details.
override func viewDidLoad() {
super.viewDidLoad()
downloadPlaceID {
detail.downloadDetails(input: place.placeId, completed: {
})
}
}

Answer 1

It should be "place_id" instead of "id"
class Place {
var placeId: String!
var vicinity: String!
var _placeId: String {
if placeId == nil {
placeId = ""
}
return placeId
}
var _vicinity: String {
if vicinity == nil {
vicinity = ""
}
return vicinity
}
init( place: [String:Any]) {
if let ids = place["place_id"] as? String {
self.placeId = ids
}
if let vicinities = place["vicinity"] as? String {
self.vicinity = vicinities
}
}
}
