Hi Jacob, nice progress on getting iOS support into ldc!  I peek at the
forums every now and then. Your approach of using an xcode test was how
I ran from the command line on an iOS device.  The idea to generate an
Xcode project with test seems good to me.

I assume you know about setupEnvAndRunTests() in

https://github.com/smolt/ldc-iphone-dev/blob/master/unittester/unittest.d

Is that still needed to pass all druntime/phobos unittests?
