Could not cast value of type '__NSDictionaryM' to 'NSArray" [duplicate]

Answer 1

The error message says

Could not cast the actual type NSDictionary to the expected type NSArray

[NSDictionary] means an array of dictionaries, but the value of response is clearly a dictionary, represented by a pair of braces.

So it's actually

let quoteDictionary = quotesData["response"] as! NSDictionary

But it's recommended to use Swift native collection types

let quoteDictionary = quotesData["response"] as! Dictionary<String,AnyObject>

Answer 2

quoteDictionary = quotesData["response"] as! [NSArray]

Now take this value from NSArray of dictionaries as [quoteDictionary][0] //returns first one

Now access that dictionary as [quoteDictionary][0][blog]
