Xcode has been doing this for as long as I've been maintaining a multi-platform application. It does indeed perform multiple compiles, one for each hardware platform. It would be nice if the warnings were only issued once but consider that at some distant point in the future (5 years, 10 years?), we might be back to a single hardware platform and it won't be a problem any more :-) Learn to live with it in the meantime :-)

I then realized that one compilation is performed for each target architecture (which seems reasonable) but each also generates the same warnings/errors (which is weird, and also a waste of time when compilation fails anyway). The editor then displays warnings/errors by bunches of 2 or 3. It would perhaps be better to compile the whole project for an architecture first, then if success perform compilation for other architectures, sending new warnings/comments to >/dev/null.

A warning may be platform dependant. You can even use two completly different code path for different architecture. Assuming that once the code is compile for an arch, everything will be identical is wrong and I hope Xcode will never do that.
