Swift Convert Any To Data - swift

Question

I'm using facebook sdk to log users in ,
every ting is going well except that after user is logged in i make a request to graph api so it returns user's data .
when i try to parse user data to codable using JSONEncoder() an error occurred !
the error is
Cannot convert value of type 'Any?' to expected argument type 'Data'
Full code :
import SwiftUI
import FBSDKLoginKit
struct AccountView: View {
#ObservedObject var loginManager = UserLoginManager()
var body: some View {
if(!loginManager.logged)
{
Button(action: {
self.loginManager.facebookLogin()
}) {
Text("Continue with Facebook")
}
}
else{
Text((loginManager.userData as AnyObject).email!)
}
}
}
struct AccountView_Previews: PreviewProvider {
static var previews: some View {
AccountView()
}
}
class UserLoginManager: ObservableObject {
#Published var logged:Bool = false
#Published var userData:Any = []
let loginManager = LoginManager()
func facebookLogin() {
// loginManager.set
loginManager.logIn(permissions: [.publicProfile, .email], viewController: nil) { loginResult in
switch loginResult {
case .failed(let error):
print(error)
case .cancelled:
print("User cancelled login.")
case .success(let grantedPermissions, let declinedPermissions, let accessToken):
print("Logged in! \(grantedPermissions) \(declinedPermissions) \(String(describing: accessToken))")
GraphRequest(graphPath: "me", parameters: ["fields": "name,picture,email"]).start(completionHandler: { (connection, result, error) -> Void in
if (error == nil){
let facebookResponse = try? newJSONDecoder().decode(FacebookResponse.self, from: result)
self.userData = facebookResponse!
self.logged = true
}
else{
print("\\\\\\\\")
print(error as Any)
}
})
}
}
}
}
// MARK: - FacebookResponse
struct FacebookResponse: Codable {
let email: String?
let id: Int?
let name: String?
let picture: Picture?
}
// MARK: - Picture
struct Picture: Codable {
let data: DataClass?
}
// MARK: - DataClass
struct DataClass: Codable {
let height, isSilhouette: Int?
let url: String?
let width: Int?
enum CodingKeys: String, CodingKey {
case height
case isSilhouette = "is_silhouette"
case url, width
}
}
and the newJSONDecoder():
func newJSONDecoder() -> JSONDecoder {
let decoder = JSONDecoder()
if #available(iOS 10.0, OSX 10.12, tvOS 10.0, watchOS 3.0, *) {
decoder.dateDecodingStrategy = .iso8601
}
return decoder
}
Hint :
let facebookResponse = try? newJSONDecoder().decode(FacebookResponse.self, from: result as! Data)
Doesn’t worked

Answer 1

Use JSONSerialization.data( to convert Any to Data
do {
let data = try JSONSerialization.data(withJSONObject: result, options: [])
self.userData = try newJSONDecoder().decode(FacebookResponse.self, from: data)
self.logged = true
}
catch {
print(error)
}
