In Swift 4.2 and Xcode 10.1

@IBAction func onClickFBSign(_ sender: UIButton) {

    if let accessToken = AccessToken.current {
        // User is logged in, use 'accessToken' here.
        print(accessToken.userId!)
        print(accessToken.appId)
        print(accessToken.grantedPermissions!)
        print(accessToken.expirationDate)

        let request = GraphRequest(graphPath: "me", parameters: ["fields":"id,email,name,first_name,last_name,picture.type(large)"], accessToken: AccessToken.current, httpMethod: .GET, apiVersion: FacebookCore.GraphAPIVersion.defaultVersion)
        request.start { (response, result) in
            switch result {
            case .success(let value):
                print(value.dictionaryValue!)
            case .failed(let error):
                print(error)
            }
        }

        let storyboard = self.storyboard?.instantiateViewController(withIdentifier: "SVC") as! SecondViewController
        self.present(storyboard, animated: true, completion: nil)
    } else {

        let loginManager=LoginManager()

        loginManager.logIn(readPermissions: [ReadPermission.publicProfile, .email, .userFriends, .userBirthday], viewController : self) { 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), \n \(declinedPermissions), \n \(accessToken.appId), \n \(accessToken.authenticationToken), \n \(accessToken.expirationDate), \n \(accessToken.userId!), \n \(accessToken.refreshDate), \n \(accessToken.grantedPermissions!)")

                let request = GraphRequest(graphPath: "me", parameters: ["fields": "id, email, name, first_name, last_name, picture.type(large)"], accessToken: AccessToken.current, httpMethod: .GET, apiVersion: FacebookCore.GraphAPIVersion.defaultVersion)
                request.start { (response, result) in
                    switch result {
                    case .success(let value):
                        print(value.dictionaryValue!)
                    case .failed(let error):
                        print(error)
                    }
                }

                let storyboard = self.storyboard?.instantiateViewController(withIdentifier: "SVC") as! SecondViewController
                self.navigationController?.pushViewController(storyboard, animated: true)

Answer 3

you can use this code to get email ,name and profile picture of user

   @IBAction func fbsignup(_ sender: Any) {
    let fbloginManger: FBSDKLoginManager = FBSDKLoginManager()
    fbloginManger.logIn(withReadPermissions: ["email"], from:self) {(result, error) -> Void in
        if(error == nil){
            let fbLoginResult: FBSDKLoginManagerLoginResult  = result!

            if( result?.isCancelled)!{
                return }


            if(fbLoginResult .grantedPermissions.contains("email")){
                self.getFbId()
            }
        }  }

}
func getFbId(){
if(FBSDKAccessToken.current() != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id,name , first_name, last_name , email,picture.type(large)"]).start(completionHandler: { (connection, result, error) in
    guard let Info = result as? [String: Any] else { return } 

            if let imageURL = ((Info["picture"] as? [String: Any])?["data"] as? [String: Any])?["url"] as? String {
        //Download image from imageURL
    }
if(error == nil){
print("result")
}
})
}
}

Answer 4

Call the below function after you logged in via Facebook.

   func getUserDetails(){

    if(FBSDKAccessToken.current() != nil){

        FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id,name , first_name, last_name , email"]).start(completionHandler: { (connection, result, error) in

            guard let Info = result as? [String: Any] else { return }

             if let userName = Info["name"] as? String
                {
                   print(userName)
                }

        })
    }
}
