Hi. i got application without any xib in it and i'd like to remake it with xib. So i want to receive view-based application. So i added Application window xib and View xib, wrote correct controllers classes named accordingly, connect all references in IB (controller, delegate, window). But when i run application view is not shown - just black screen. I tried to copy/paste code and double check all references from empty created View based application but with same result. what i'm doing wrong?
