var facebookAccount: ACAccount?

        let options: [NSObject : AnyObject] = [ACFacebookAppIdKey: "YOUR_FACEBOOK_API_KEY", ACFacebookPermissionsKey: ["publish_stream","publish_actions"],ACFacebookAudienceKey:ACFacebookAudienceFriends]
        let accountStore = ACAccountStore()
        let facebookAccountType = accountStore.accountTypeWithAccountTypeIdentifier(ACAccountTypeIdentifierFacebook)

            accountStore.requestAccessToAccountsWithType(facebookAccountType, options: options) { (granted, error) -> Void in
                if granted
                {
                    let accounts = accountStore.accountsWithAccountType(facebookAccountType)
                    self.facebookAccount = accounts.last as? ACAccount
                    let accountsArray=accountStore.accountsWithAccountType(facebookAccountType) as NSArray

                    self.facebookAccount=accountsArray.lastObject as? ACAccount
                    var dict:NSDictionary
                    dict=NSDictionary()

                    dict=self.facebookAccount!.dictionaryWithValuesForKeys(["properties"])

                else
                {
                    if error.code == Int(ACErrorAccountNotFound.rawValue) {
                        dispatch_async(dispatch_get_main_queue(), { () -> Void in
                            self.displayAlert("There is no Facebook accounts configured. you can add or created a Facebook account in your settings.")

Swift 3 Version of solution @reena

@IBAction func loginButtonPressed(_ sender: UIButton) {

    var facebookAccount: ACAccount?
    let options:[String : Any] = [ACFacebookAppIdKey: "YOUR_FACEBOOK_API_KEY", ACFacebookPermissionsKey: ["email"],ACFacebookAudienceKey:ACFacebookAudienceFriends]

    let accountStore = ACAccountStore()

    let facebookAccountType = accountStore.accountType(withAccountTypeIdentifier: ACAccountTypeIdentifierFacebook)

    accountStore.requestAccessToAccounts(with: facebookAccountType, options: options) { (granted:Bool, error:Error?) in
        if granted{
            let accounts = accountStore.accounts(with: facebookAccountType)
            facebookAccount = accounts?.last as? ACAccount

            let dict:NSDictionary = facebookAccount!.dictionaryWithValues(forKeys: ["properties"]) as NSDictionary
            let properties:NSDictionary = dict["properties"] as! NSDictionary

            print("facebook Response is-->:%@",properties)
        }
        else {
            if let err = error as? NSError, err.code == Int(ACErrorAccountNotFound.rawValue) {
                DispatchQueue.main.async {
                    self.displayAlert("There is no Facebook accounts configured. you can add or created a Facebook account in your settings.")
                }
            } else {
                DispatchQueue.main.async {

Import Social and Acount Framwork

put this code in your .m file
