Get value from dictionary as an array in Swift 2

I am relatively new to swift and I have a little problem here. I have a JSON already serialized as a dictionary. This is how I get the dictionary

guard let result = try NSJSONSerialization.JSONObjectWithData(responseData, options: []) as? [String:AnyObject] else {
                    print("Error trying to convert data to JSON")
                    completionHandler(nil, response, error)
                    return
                }

Here is my dictionary

{
  "count": "68",
  "earthquakes": [
    {
      "src": "us",
      "eqid": "b000gbf8",
      "timedate": "2013-04-19 03:05:53",
      "lat": "46.1817",
      "lon": "150.7960",
      "magnitude": "7.2",
      "depth": "122.30",
      "region": "Kuril Islands"
    },
    {
      "src": "us",
      "eqid": "b000g7x7",
      "timedate": "2013-04-16 10:44:20",
      "lat": "28.1069",
      "lon": "62.0532",
      "magnitude": "7.8",
      "depth": "82.00",
      "region": "Iran-Pakistan border region"
    }
  ]
}

I want to get those earthquakes as an array that I could iterate every item in it.

I try to create a temp var for that

let eqs = resultJSON["earthquakes"]

But, I can't iterate through eqs. My point is, I want to make an array that comes from that dictionary.

How is that possible? Any help would be appreciated. Thank you.

The key earthquakes contains the array which has String keys and values

if let earthquakes = result["earthquakes"] as? [[String:String]] {
    for earthquake in earthquakes {
        let lat = earthquake["lat"]!
        let lon = earthquake["lon"]!
        // get other values
        print(lat, lon)
    }
}
