Quite often I find myself in the Terminal and want to open Xcode with the project in the current directory:

% open CurrentProject.xcodeproj

This works just fine, of course, but with the following alias (added to ~/.cshrc), I don't need to know the name of the project, assuming there is always only one project in the current directory:

% alias xcode '\ls | grep xcodeproj | xargs open'
% xcode

N.B. The use of \ls ignores the alias that I have for 'ls'. Instead of ls *.xcodeproj, the pipe via grep avoids errors like "ls: No match.".

P.S. Knowing the name of the project is actually not the problem; since there are multiple items named "Current" or "CurrentProject" in the same folder, the issue is that I can't just type open SHIFT+C<TAB><CR> (where pressing TAB autocompletes the name); instead, I have to type: open SHIFT+C<TAB>SHIFT+P<TAB>.x<TAB><CR>.

Update

The Xcode text editor invocation tool xed can achieve much the same thing; just type:

% xed .

Trying to update Xcode 4.0.1 from within the Mac AppStore application, I was greeted with this error message:

You have updates available for other accounts Sign in to (null) to update applications for that account.

There exist numerous forum entries on Apple's discussion board on that subject and the recommended solution is to trash the "Install Xcode" application and then to re-launch the AppStore, selecting to re-install Xcode.

I trashed "Install Xcode" but AppStore produced the same message. Relaunched one additional time and it allowed me to update (note: not install). However, when it was finished, there was no new "Install Xcode" in the Applications folder!

It turns out, the AppStore had located and updated a different copy of the software on a separate drive where I had made a backup, even though I had renamed it to "Install Xcode-4.0.1". Its info window revealed that it had been modified and that its version number now was 4.0.2.

Installation from that modified backup worked correctly.

The old backup could be restored from the version that I had put into the trash.

Searched for it online and found this solution, which worked fine for me (Xcode 3.0):

defaults write com.apple.xcode  PBXCustomTemplateMacroDefinitions  \
        '{ ORGANIZATIONNAME = "tredje design"; }'
