Can't I leave out #import "foo.h" in .m file if it's already in the prefix header?
The product still builds successfully when I leave it out. But, I've noticed that the Xcode templates keep them in. Why?
Is the answer the same for #include?
I don't know why it does this, but it doesn't hurt because #import protects from double #include by checking if something is already #import-ed or #include-d, so no, the same scenario wouldn't work with #include.
