codesign_allocate: error: unable to find utility "codesign_allocate", not a developer tool or in PATH

Question

I upgraded my Mac to 10.10.3 and Xcode to 6.3.1 yesterday; today I can't use git, codesign_allocate....and more.

`sh: line 1: 18421 Abort trap: 6           /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -sdk /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.3.sdk -find codesign_allocate 2> /dev/null

Try running the following command:

locate codesign_allocate

Note, you may need to run this command and wait a couple minutes if your locate DB isn't updated:

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.locate.plist

Then see all the spots where codesign_allocate exists. On my system, it shows up in the following locations:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/codesign_allocate
/Library/Developer/CommandLineTools/usr/bin/codesign_allocate
/usr/bin/codesign_allocate

Then ensure at least one of these is on your $PATH.

echo $PATH | tr : '\n'

On my system, /usr/bin is on my $PATH, so Xcode finds it just fine. If codesign_allocate isn't available on your $PATH, you've got two options:

1. Add it to your path. I.e. edit your ~/.bashrc and add this line to the end (Note, you can use any path that codesign_allocate exists on. The path I'm using is just to illustrate):

   export PATH=$PATH:/Library/Developer/CommandLineTools/usr/bin/

2. Create a symbolic link to your command line tools somewhere on a directory in your path:

   sudo ln -s /Library/Developer/CommandLineTools/usr/bin/* /usr/bin/

Hope this helps! Note, on installation of a new Xcode version, you may want to revisit this and ensure you're using the correct paths. Assuming you install over previous versions of Xcode, you should be okay, but it's something to keep in mind.
