Facebook Graphrequest for Swift 5 and Facebook Sdk 5

facebook graph request using swift 5

I got the same behavior. I am not that experienced in Swift and the Facebook Graph API and I'm not sure if it is a good solution but, currently (until I find a better solution), for me works:

connection.add(GraphRequest(graphPath: "/me", parameters: ["fields":"email"])) { httpResponse, result, error   in
    if error != nil {
        NSLog(error.debugDescription)
        return
    }

    // Handle vars
    if let result = result as? [String:String],
        let email: String = result["email"],
        let fbId: String = result["id"] {

        // internal usage of the email
        self.userService.loginWithFacebookMail(facebookMail: email)

    }

}

Converting Graph API from Swift 3 to Swift 5 for Facebook SDK

        func getFacebookProfileInfo() {
        let requestMe = GraphRequest.init(graphPath: "me", parameters: ["fields" : "id,name,email,picture.type(large)"])
        let connection = GraphRequestConnection()
        connection.add(requestMe, completionHandler: { (connectn, userresult, error) in
            if let dictData: [String : Any] = userresult as? [String : Any] {
                DispatchQueue.main.async {
                    if let pictureData: [String : Any] = dictData["picture"] as? [String : Any] {
                        if let data : [String: Any] = pictureData["data"] as? [String: Any] {

                            print(data)
                            print(dictData["email"]!)

                        }
                    }
                }
            }
        })
        connection.start()
    }

Facebook Graph API: Swift SDK not working: GraphRequest

However i implement facebook login my app which works fine.

On button click I called facebook login using LoginManager.

@IBAction func continueWithFacebook(_ sender: Any) {
    let fbLoginManager : LoginManager = LoginManager()
    fbLoginManager.logIn(permissions: ["email"], from: self) { (result, error) -> Void in
        if (error == nil){
            let fbloginresult : LoginManagerLoginResult = result!
            if (result?.isCancelled)!{
                return
            }
            if(fbloginresult.grantedPermissions.contains("email")) {
                self.getFBUserData()
            }
        }
    }
}

After that I get the data of user using GraphAP

func getFBUserData() {
    if((AccessToken.current) != nil){
        GraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email"]).start(completionHandler: { (connection, result, error) -> Void in
            if (error == nil){
                guard let userDict = result as? [String:Any] else {
                    return
                }
                if let picture = userDict["picture"] as? [String:Any] ,
                    let imgData = picture["data"] as? [String:Any] ,
                    let imgUrl = imgData["url"] as? String {
                    self.uURLString = imgUrl
                    /*let url = URL(string: imgUrl)*/
                    print(imgData)
                }
                if let n = userDict["name"] as? String {
                    self.name = n
                }
                if let e = userDict["email"] as? String {
                    self.email = e
                }
                self.socialLogIn()
             }
        })
    }
}

Add in your pod file -
pod 'FBSDKCoreKit' and
pod 'FBSDKLoginKit'

Try using like this you will get your derided result.
Happy Coding

Showing a Facebook User Picture using the URL (Swift 5 | Xcode 10)

Try the below code.

func getFacebookProfileInfo() {
    let requestMe = GraphRequest.init(graphPath: "me", parameters: ["fields" : "id,name,email,picture.type(large)"])

    let connection = GraphRequestConnection()

    connection.add(requestMe, completionHandler:{ (connectn, userresult, error) in

        if let dictData: [String : Any] = userresult as? [String : Any]
        {
            DispatchQueue.main.async
                {
                    if let pictureData: [String : Any] = dictData["picture"] as? [String : Any]
                    {
                        if let data : [String: Any] = pictureData["data"] as? [String: Any]
                        {
                            print(data)
                            print(dictData["email"]!)     

                            if let pictureURL = pictureData["url"] as? String { //image url of your image

                                   if let url = URL(string: pictureURL) {

                                       if let data = try? Data(contentsOf: url) { //here you get image data from url

                                          //generate image from data and assign it to your profile imageview
                                          imageView.image = UIImage(data: data) 
                                       }
                                   }
                            }
                      }
                  }
              }
          }
      })
      connection.start()
  }

I hope it will help you to get the image from the URL.

Facebook ios sdk Graph request allows only one field as parameter

I too got the same error when trying with the latest release. I suggest you to downgrade to the previous version. For me below versions are working fine:

pod 'FBSDKCoreKit', '~> 4.38.0' 
pod 'FBSDKLoginKit', '~> 4.38.0' 

After that run

pod deintegrate

pod install

Swift version of Facebook iOS SDK and how to access data in Response

I faced this problem today as well. I got the user id and name inside MyProfileRequest

struct Response: GraphResponseProtocol {
    init(rawResponse: Any?) {
        // Decode JSON from rawResponse into other properties here.
        guard let response = rawResponse as? Dictionary<String, Any> else {
            return
        }

        if let name = response["name"],
            let id = response["id"] {

            print(name)
            print(id)
        }
    }
}

EDIT: I redesigned my code like this to use the values in .success(let response) case

struct Response: GraphResponseProtocol {

    var name: String?
    var id: String?
    var gender: String?
    var email: String?
    var profilePictureUrl: String?

    init(rawResponse: Any?) {
        // Decode JSON from rawResponse into other properties here.
        guard let response = rawResponse as? Dictionary<String, Any> else {
            return
        }

        if let name = response["name"] as? String {
            self.name = name
        }

        if let id = response["id"] as? String {
            self.id = id
        }

        if let gender = response["gender"] as? String {
            self.gender = gender
        }

        if let email = response["email"] as? String {
            self.email = email
        }

        if let picture = response["picture"] as? Dictionary<String, Any> {

            if let data = picture["data"] as? Dictionary<String, Any> {
                if let url = data["url"] as? String {
                    self.profilePictureUrl = url
                }
            }
        }
    }
}

And in the success case you can get the values like this:

let connection = GraphRequestConnection()
connection.add(MyProfileRequest()) { response, result in
  switch result {
  case .success(let response):
    print("My facebook id is \(response.id!)") //Make sure to safely unwrap these :)
    print("My name is \(response.name!)")
  case .failed(let error):
    print("Custom Graph Request Failed: \(error)")
 }
}
connection.start()

Handle if user cancels Facebook-Login in Swift 5

You need to handle 3 cases

 if error != nil {
      print("Facebook login failed. Error \(error)")
 } else if result?.isCancelled == true { 
     print("Facebook login was cancelled.")
 } else { 
   // clicked ok go on 
 }

Facebook Graph Request using Swift3 -

Browsing on the github issues, i found a solution.

https://github.com/facebook/facebook-sdk-swift/issues/63

Facebook documentation for Swift 3.0 and SDK 0.2.0 is not yet updated.

This works for me:

    let params = ["fields" : "email, name"]
    let graphRequest = GraphRequest(graphPath: "me", parameters: params)
    graphRequest.start {
        (urlResponse, requestResult) in

        switch requestResult {
        case .failed(let error):
            print("error in graph request:", error)
            break
        case .success(let graphResponse):
            if let responseDictionary = graphResponse.dictionaryValue {
                print(responseDictionary)

                print(responseDictionary["name"])
                print(responseDictionary["email"])
            }
        }
    }

enjoy.
