I have an autolayout xib with Size Classes enabled. The view looks great in all the phone sizes under "Simulated Metrics" but when I install the app on the phone only the last layout that was selected under "Simulated Metrics" gets loaded. For example, if I choose iPhone 5.5-inch under simulated metrics and install it on an iPhone 4S the layout the iPhone 5.5-inch gets installed on the 4S, making it go off the screen.
Is there a setting or something I've messed up which says to only build the currently selected layout?
