That sounds like the main thread was blocked for the duration. The only other
common reason for something like this is that the work is being done off the
main thread and the thread took that long to die (which would also be an
invalid way to use UIKit).

The item should be encoded (and decoded), but I’m not certain why this would be
from the looks of it. If you do this all in code however you need to assign
your own bar button item to the barBackButtonItem (it defaults to nil).
