 ### Add the link handlers to the AppDelegate
 
 When a user finishes their log in flow, Facebook or Google will redirect back into the app. Simplicity will listen for the access token or error. You need to add the following lines of code to `AppDelegate.swift`:
 
 ```Swift
 import Simplicity
 
-func application(_ app: UIApplication, openURL url: URL, options: [UIApplicationOpenURLOptionsKey: Any]) -> Bool {
-  return Simplicity.application(app, openURL: url, options: options)
+func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey: Any]) -> Bool {
+    return Simplicity.application(app, open: url, options: options)
 }
 
-func application(_ application: UIApplication, openURL url: URL, sourceApplication: String?, annotation: Any) -> Bool {
-  return Simplicity.application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
+func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
+    return Simplicity.application(application, open: url, sourceApplication: sourceApplication, annotation: annotation)
 }
