If I set the build architecture as 32bit in Xcode, do my app runs on 64bit machines?

A basic question about building in 32/64 architecture with Xcode

If I set the build architecture as 32bit in Xcode, do my app runs on 64bit machines? Is it going to run much slower?

Yes, 32 bit apps run just fine on 64 bit OS X. They may run slightly faster or slower in certain cases, but the difference is generally negligible. The only real limitation is the size of your virtual address space, i.e. 4 GB for a 32 bit app.
