I had a problem using one of my own frameworks in MacRuby.  gen_bridge_metadata was giving me the following:<div><br></div><div><div>Received exception: can&#39;t convert nil into String:</div><div>/usr/bin/gen_bridge_metadata:573:in `+&#39;</div>
<div>/usr/bin/gen_bridge_metadata:573:in `encode_includes&#39;</div><div>/usr/bin/gen_bridge_metadata:2091:in `handle_framework&#39;</div><div>/usr/bin/gen_bridge_metadata:882:in `prepare&#39;</div><div>/usr/bin/gen_bridge_metadata:882:in `each&#39;</div>
<div>/usr/bin/gen_bridge_metadata:882:in `prepare&#39;</div><div>/usr/bin/gen_bridge_metadata:721:in `parse&#39;</div><div>/usr/bin/gen_bridge_metadata:2321</div><div>/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/optparse.rb:791:in `initialize&#39;</div>
<div>/usr/bin/gen_bridge_metadata:2252:in `new&#39;</div><div>/usr/bin/gen_bridge_metadata:2252</div><div>can&#39;t convert nil into String</div></div><div><br></div><div>After some debugging, I found out it was because my framework was named &quot;audio-utilities&quot; and the code in handle_framework expects the framework name to match the regular expression (\w+) which doesn&#39;t support the dash character.  Xcode doesn&#39;t complain about that name.  Are frameworks supposed to conform to a particular naming convention or is gen_bridge_metadata being too restrictive?</div>
