xcode - What is a target dependency?

Question

I feel so noob asking this question, but what is a target dependency? I see it all the time in Xcode.

Answer 1

A dependency is another target that must be built before the current target can be. For example, if you have an app target and a framework target, the app target can have the framework target as a dependency, to ensure that the framework is built first. That is, the app target "depends" on the framework.
