Error logging in to iOS9 Facebook LoginOpenURL

Question

I have a problem with Facebook SDK 4.6 using iOS9 and Xcode7.

When testing on the device, nothing happens, when I press the login button and in iOS Simulator, I get an error message.

2015-10-01 17:12:32.197 TestProject[32112:797172] -canOpenURL: failed for URL: "fbauth2:///" - error: "(null)" 

In my plist file, I have included the following

 <key>NSAppTransportSecurity</key> <dict> <!--Include to allow all connections (DANGER)--> <key>NSAllowsArbitraryLoads</key> <true/> </dict> <key>LSApplicationQueriesSchemes</key> <array> <string>fbauth</string> <string>fbapi</string> <string>fb-messenger-api</string> <string>fbauth2</string> <string>fbshareextension</string> </array> <key>CFBundleURLTypes</key> <array> <dict> <key>CFBundleURLSchemes</key> <array> <string>fb{FACEBOOK_APP_ID}</string> </array> </dict> </array> <key>FacebookAppID</key> <string>{FACEBOOK_APP_ID}</string> <key>FacebookDisplayName</key> <string>{Your App Name}</string>

This is just a launch warning that lets you know that an application that processes this circuit is not installed on the phone.

There is a note about this in Facebook docs:

This is an Xcode warning indicating that canOpenURL: call returned false. As long as you configured the LSApplicationQueriesSchemes entry in your plist as described above, you can ignore this warning

Can you share your AppDelegate code and the code you are trying to log into? Maybe there is something there ...
