How to use Facebook iOS SDK on iOS 10


Error OSStatus -10814 occures when canOpenURL: can't find any application, that can open this URL (actually, Facebook trying to find their application by calling canOpenURL: with argument "fbauth2:/"). Printing happens inside of function, so you can't do anything with that.But if you will run your application on device with installed Facebook app, you will not see this error.

Error 308 occures because of the situation, when value, stored in keychain is not equal to value, that is stored in facebook completion parameters (for more information you can check -[FBSDKLoginManager completeAuthentication:expectChallenge:]).

It happens because Apple changed the way of working with keychain in iOS 10. To fix this issue you simply should go to Targets->Capabilities and enable keychain sharing (it enables access to keychain for your app):image

If you are using Xamarin (read this link for more information, thanks @dynamokaj):

Just make sure you enable the keychain access in Entitlements and select the entitlements for Simulator (Debug) builds too. By default this is not set.


Same problem was in my app, i checked many solution but did't works for me. I've fix this problem using below method.

Go to this Link Select Your App and configure your info.plist

import and add this code in your AppDelegate

import FBSDKCoreKitimport FBSDKLoginKitfunc application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {    return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)}func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {    return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, options: options)}


The main reason why you're getting the following error,

canOpenURL: failed for URL: "fbauth2:/" - error: "The operation couldn’t be completed. (OSStatus error -10814.)

is that your iOS simulator does not have the Facebook Application installed. Until you install the application on your iOS simulator, you will continue to get the error. Try running your iOS application on a provisioned iOS device with Facebook installed and you will not see the error message again. Hope this helps!
