Writing code in iOS is tedious, but IB is also dog slow and XCode becomes pretty unresponsive every time I switch to/from it. Not to mention the mess xibs make in source control. There is no reason for xibs to be human readable -- a binary format would limit diff hemorrhaging, and performance would certainly be helped by not having to process unholy amounts of XML. Either way, good luck merging xibs with multiple collaborators.
