I use FBSDK with Xcode 7.2.1 to retrieve user profile information and use SwiftyJson to handle and manipulate json data. After changing values / removing some i want to make a post request to my api with the JSON data. But i am stucked with the really bad type issues in swift.
This is my code to make a post request:
let headers = [ "Content-Type": "application/json" ] let userProfile = userProfile as? [String : AnyObject] Alamofire.request(.POST, "http://localhost:8888/api/profile", parameters: userProfile, headers: headers, encoding:ParameterEncoding.URL) .response { request, response, data, error in print(userProfile) //This prints nil print(response) //This prints api error for expecting data } Unfortunately i receive this error:
Cast from 'JSON' to unrelated type '[String : AnyObject]' always fails
If i try to send the JSON data directly to API i receive this error:
Cannot convert value of type 'JSON' to expected argument type '[String : AnyObject]?'
Any help are appreciated. I just want to know, how to convert JSON object to String AnyObject? without failing. Or sending Json object as post / put / patch request data with Swift 2.

JSON is a custom type defined in SwiftyJson. Try using userProfile.dictionaryObject in your case to get the underlying swift Dictionary.
Unwrap the optional dictionary by this
if let userProfile = userProfile.dictionaryObject { Alamofire.request(.POST, "http://localhost:8888/api/profile", parameters: userProfile, headers: headers, encoding:ParameterEncoding.URL) .response { request, response, data, error in print(userProfile) //This prints nil print(response) //This prints api error for expecting data } }
