Xcode 4 - Using existing projects

Question

I have this weird problem which I don't remember to ever had in XCode 3.

I have my head project which I was developing. Now I want to use another project, but when I drag the.xcodeproj file to my head project from my other project, all it copies is the.xcodeproj file, without nothing else (groups,source files, etc..). I remember on Xcode 3 it was asking if to copy or just reference the new project. But now nothing.

Should I do it differently on XCode 4?

I even tried to play with a new workspace, but it still behaves the same.

Answer 1

It seems to be treating the.xcodeproj as a resource like an image or other stuff. I think you'l have to open the other project you want to work with and drag in all the files manually.

Maybe there's a better way, but try doing that for now:)

Answer 2

Seems like closing and reopening XCode fixed the issue, it's weird that I have to do it everytime now that I want to reference a new project. oh well.
