Assertion failure in void _UIPerformResizeOfTextViewForTextContainer

I am importing a file from BOX. I have used box sdk V2. It's importing successfully but as it imports the screen has to navigate on a next controller. I am having crash on this

NSArray *arrayOfViews = [[NSBundle mainBundle] loadNibNamed:@"CategoryOptionView"
owner:nil
options:nil];


and this is the error

_UIPerformResizeOfTextViewForTextContainer(NSLayoutManager *, UIView *, NSTextContainer *, NSUInteger)(),

Answer

Well, the exception reason gives the problem away; you should run this code on the main thread. Try enclosing the view creation and nib loading using dispatch_sync or dispatch_async and passing the main queue using dispatch_get_main_queue().
