How to access my json data from type Any in swift?

Question

I am using Alamofire to perform my network calls. The return from the response(call below) returns a type ANY. How do i get access to my array of dictionaries?

Almofire documentation:

 Alamofire.request("https://httpbin.org/get").responseJSON { response in
debugPrint(response)

if let json = response.result.value {
    print("JSON: \(json)")
   }
}

I have tried the following:

let json2 = json as! [[String:String]]

JSON:

 (
    (
            {
        docURL = "https://httpbin.org/get/rab1Mpub.pdf";
        name = "rab1Mpub.pdf";
    }
),
    (
            {
        docURL = "https://httpbin.org/get/1Mpublic.pdf";
        name = "1Mpublic.pdf";
    }
),
    (
            {
        docURL = "https://httpbin.org/get/plantLabBook";
        name = "plantLabBook_1.pdf";
    }
)
)

I just get the following error:

 Could not cast value of type '__NSArrayI' (0x10740c648) to 'NSDictionary' (0x10740b1a8).

Answer 1

You have an array, of an array, of a dictionary:

let json = json as! [[[String:String]]]

for outer in json {
    for inner in outer {
        for (key, value) in inner {
            print(key, "has", value)
        }
    }
}

NOTE: as! should be done only if you're absolutely sure of the object type. i.e that the API will always send [[[String:String]]].

PS: I personally use SwiftyJSON to make my life easier when I need to work with nested structures.
