When building an Xcode project, the file doesn't have any
import clause at the top, yet it implicitly imports some modules - I know it because I can use it and it compiles. Now, If I'd like to debug what is actually happening with the imports here, what are the possibilities? I'd like to learn about import tree or something that is used by this file when being compiled.
The thing is that the
import A from another file, that seems unrelated to the file I examine, decide whether the module is available or not.
Appreciate any tips.
