Alamofire can't access keys of json response

Question

I\'m new to using Alamofire and have encountered an issue. I\'m able to run the following code to print out all the data from an API endpoint.

Alamofire.request(         


        

Answer 1

You are trying to get the value with getting the object, try this:

Alamofire.request("http://codewithchris.com/code/afsample.json").responseJSON { response in
if let result = response.result.value {
    let JSON = result as! NSDictionary
    print(JSON["firstkey"])
}
}

Hope it will work!

Answer 2

You should add ! at the end of code before ) to force unwrap the value

   Alamofire.request("http://codewithchris.com/code/afsample.json").responseJSON { response in
      if let JSON = response.result.value {
      let json = JSON as! [String: Any]
      print(json["firstkey"]!)
   }
}

Answer 3

This is really simple. You just need to force cast (as!) your JSON. so change your code to this and it will work:

Alamofire.request("http://codewithchris.com/code/afsample.json").responseJSON { response in
    if let JSON = response.result.value {
        let json = JSON as! [String: Any]
        print(json["firstkey"])
    }
}

Edit 1: As you said in comments that you are using SwiftyJSON package. Sample code is as follows:

Alamofire.request("http://codewithchris.com/code/afsample.json").responseJSON { response in
        if let value = response.result.value {
            let json = JSON(value)
            print(json["firstkey"].stringValue)
        }
    }

Alamofire.request("https://mmcalc.com/api").responseJSON { response in
        if let value = response.result.value {
            let json = JSON(value)
            print(json.arrayValue[0]["uniqueUsers"].stringValue)
        }
    }
