That's indeed needed and was forgotten to be added also to the template (the
example applications all go it). Want to provide a patch?

That would indeed be interesting. Did you base it on the GObject-Introspection
information to also get information about how to do memory management?

Yes you currently have to use the GNU C++ STL, see bug #766366. Which generally
means that your "target" iOS version has to be set to 6.0 (or 7.0?) currently
to make this work out of the box.

That's a bug in the 1.11.1 development release on platforms using static
linking. Try 1.10.2 instead.

We don't built with bitcode, simply because it's not generally possible or easy
to do. Quite a few libraries have assembly optimizations and are not plain C.
