I created an custom keyboard using the default template in Xcode 6 and when I run it in the simulator I see a keyboard with a "Next Keyboard" button. However, when I try to run the app on my iOS 8 device, the keyboard will show up in settings but when I try to use it in the messages app the keyboard will not display. How can I use the custom keyboard on a device rather than in the simulator?
I fixed this by turning guided access off in accessibility settings.
