I searched this but I haven't found the exact answer I'm looking for. I'm trying to email a friend/co-worker a saved xcode project I'm working on. If I send attach my saved file in an email when he opens it up everything is kinda red and theres no code or anything. How can I send the whole project so that he can access it? Thanks.
It sounds like you are sending him just the Xcode project file, but you will need all the source files.
If you assume your project is in:
/Users/me/Projects/MyDeadGoodProject/
MyDeadGoodProject (folder with source)
MyDeadGoodProject.xcodeproj (project bundle)
(Which is fairly standard)
Then you need to send the whole of the top-level project directory structure.
This is best done by zipping up the whole lot, which can be done from Finder by right-clicking and selecting "Compress MyDeadGoodProject" or from the command line (Terminal.app) using zip:
$ cd ~/Projects
$ zip -r9 MyDeadGoodProject.zip MyDeadGoodProject
And then e-mail him the .zip file.
If you co-operate with someone else on a regular basic then it's best to get some central git hosting going, as that will be much easier to manage.
