Xcode how to add an external project

问题:

I need to add an external project to my Xcode project, the reason for this is I need to add a Target Dependency on that external projects static library.

I can't seem to add it in the way I need, I would like it like this:

However, when I add another project to my actual Xcode project I get the following which doesn't let me explore that project from my one and so I can't add the dependency I need.

Note that these screenshots are from two different projects, and in the one which is showing me what I want to reproduce in my own project, dragging in multiple projects works as expected.

Maybe I have some settings set up wrong in my project ? All I've done is take a template detail-master application from Xcode.

回答1:

You did it right. The problem is that Xcode cannot have the same project opened twice.

Close Serenity.xcodeproj before reopening your parent project.

回答2:

Yes, this is possible, it's called a workspace.

In your example:

• Open both of your projects
• Drag the Serenity project into the Dependant project

I think what you are doing wrong is dragging the Xcodeproj, try opening that project and dragging the project block instead (see pic)
