I keep searching, but cannot find a clear and simple explanation on how to include one XCode project, along with all of it's sub-classes into another project. I routinely see stuff like that in sample projects that I download off the web, but do not know how to do this myself.
Within XCode, along with .h and .m files, and folders, there's a whole new project, starting with a blue xcode project icon, that is expandable to contain everything within the project.
Please, can someone explain to me step by step what do I need to do to add one XCode project into another one? I've seen a ton of one liners like "header search paths", but that does not tell me much.
UPDATE: After re-reading the documentation, I realized that the project to include must be dragged ONTO the BLUE project icon of the parent project. Regular sources can be dragged anywhere, but a project must be dragged onto a project.
Thank you!
