I am trying to use Slidden keyboard on the iOS simulator, but it doesn't show up as an option when tapping in a textfield.
I have tried Hardware > Keyboard > Toggle Software Keyboard (Shift + Cmd + K)

I have added the keyboard in the preferences

But when I tap inside a textfield, only the default English and Emoji keyboards show up!

What am I missing here?
I am using Xcode 6.1, and the iOS simulator version 8.1
