Hello I am working on an IOS app that login into facebook and get all your facebook friends profile picture, name and gender, which is basically like tinder but based on facebook friends
My question is how to get my friends profile picture name and gender

You need to ask the read permission for email and profile_picture to FBSDKLogin Manager

FBSDKLoginManager().logIn(withReadPermissions: ["email", "public_profile"]

Also in GraphRequest ask for fields you require

FBSDKGraphRequest(graphPath: "/me", parameters: ["fields" : "id, name, first_name, last_name, gender, email, birthday, picture"])

Please see below code for reference

btn_Facebook.addTarget(self, action: #selector(handleCustomFBLogin), for: .touchUpInside)



///FACEBOOK LOGIN

func handleCustomFBLogin(sender:UIButton!){

    FBSDKLoginManager().logIn(withReadPermissions: ["email", "public_profile"], from: self) { (result, err) in

        if(err != nil){

            print("Custom FB Login Failed")

            return

        }

        //print(result?.token.tokenString)

        self.showEmailAddress()

    }

}



func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!){

    if(error != nil){

        print(error)

        return

    }

    print("Successfully Logged in using facebook")

    showEmailAddress()

}



func showEmailAddress(){

    let accesstoken = FBSDKAccessToken.current();

    guard let accessTokenString = accesstoken?.tokenString else {return}



    FBSDKGraphRequest(graphPath: "/me", parameters: ["fields" : "id, name, first_name, last_name, gender, email, birthday, picture"]).start { (connection, result, err) in

        if(err != nil){

            print("Failed to start GraphRequest", err ?? "")

            return

        }

        print(result ?? "")

        if(result != nil){

            self.sendDetailsForFacebookLogin(result: result as! NSDictionary)

        }else{

            MyCustomAlert.sharedInstance.ShowAlert(vc: self, myTitle: StringClass.sharedInstance.lcStr_loginfailedcaps, myMessage: StringClass.sharedInstance.lcStr_plsTryAgain)

        }



    }



}



func loginButtonDidLogOut(_ loginButton: FBSDKLoginButton!){

    print("Logged out of Facebook")

}



func sendDetailsForFacebookLogin(result:NSDictionary){

    //print(result)



    var theemail:String = ""

    var thefname:String = ""

    var thelname:String = ""

    var thedob:String = ""

    var thecity:String = ""

    var thereunder:String = “”



    if result["email"] != nil {

        theemail = (result.value(forKey: "email") as? String)!

    }

    if result["first_name"] != nil {

        thefname = (result.value(forKey: "first_name") as? String)!

    }

    if result["last_name"] != nil {

        thelname = (result.value(forKey: "last_name") as? String)!

    }

    if result["birthday"] != nil {

        thedob = (result.value(forKey: "birthday") as? String)!

    }

    if result["city"] != nil {

        thecity = (result.value(forKey: "city") as? String)!

    }

    if result[“gender”] != nil {

        thegender = (result.value(forKey: “gender”) as? String)!

    }



    let picDict:NSDictionary = result.value(forKey: "picture") as! NSDictionary

    let dataDict:NSDictionary = picDict.value(forKey: "data") as! NSDictionary

    let theimg:String = dataDict.value(forKey: "url") as! String
