The order of the source files in the Compile Sources phase of the
target
controls link order. Drag them into the order you need.
This says nothing about the order the globals are initialized, though.
If you need a specific ordering, you need to explicitly initialize
the variables in code.
I'd thought so, myself, but in Googling the problem, I had the
impression that Xcode engineers, at least for previous versions,
believed link order controlled initialization order.
I do agree that if you want things to happen one after the other, the
way to do that is to write code that makes them happen, one after the
other. This link-order business says "implementation detail" to me,
and I should have said so in the first place.
