swift: cannot subscript a value of type [Dictionary<String, AnyObject>] with an index of type string

Question

I am trying to json parsing in swift 3. I am getting the above mentioned error. My parsing technique is as follows:

if let responseData = data {
   do {
     let json = try JSONSerialization.jsonObject(with: responseData, options: JSONSerialization.ReadingOptions.allowFragments)
     if let dict = json as? [Dictionary<String, AnyObject>] {
        if let localityName = dict["name"] as? String ,let localityId = dict["_id"] as? String {

         }               
     }           
   } catch {
       print("could not serialize")            
   }
}

I am getting the error in the line:

if let localityName = dict["name"] as? String ,let localityId = dict["_id"] as? String

please let me know how can I fix this issue

Answer 1

The dict property is an array of dictionaries, not a dictionary. You could access the first elements name the following:

dict.first?["name"]

Answer 2

dict is actually arr . Create a loop to iterate thru it

if let arr = json as? [Dictionary<String, AnyObject>] {
   for item in arr {
      if let localityName = item["name"] as? String,
         let localityId = item["_id"] as? String {
         print(localityName, localityId)
      }
   }
}
