Could not cast NSDicationry with NSData in WebService call request - ios

Question

Trying to wrap Codable response data from WebService
used cocoa pod
pod 'WebService', '~> 0.4'
var webServiceObject : WebService = WebService()
webServiceObject.sendRequest(URLString, parameters: parameters as NSDictionary?, requestType: .post, success: {response,data in
do{
// Handle data when request Success
let jsonDecoder = JSONDecoder()
do {
let result = try jsonDecoder.decode([ResponseModelValue].self, from: data as! Data)
print(response?.statusCode as Any)
print("Success Response Value", result)
}
} catch {
print(error)
}
}, failed: {
(response : HTTPURLResponse?, ResponseDict : Any?) in
print(response?.statusCode as Any)
print("Failed Response Dictionary", ResponseDict!)
// Handle data when request fails
}, encoded: false )
I got following error
Could not cast value of type '__NSDictionaryI' (0x10c81ab38) to 'NSData' (0x10c819620).
Can any one suggest me what I done wrong here, so I can parse proper response data with codable [ResponseModelValue]

After looking at that library, it appears that it will turn the response into a dictionary if possible and fall back to returning data.
https://github.com/kansaraprateek/WebService/blob/master/WebService/Classes/WebService.swift#L281
It doesn't appear like there is a way to configure that behaviour. The library was also created before Codable was created. You may need to reach out the library owner for a fix, fork the repo and fix it yourself, or switch to using URLSession since the code you posted is mostly the same as a URLSession call.
