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

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 $PATH, you've got two options:
Add it to your path. I.e. edit your
~/.bashrcand add this line to the end (Note, you can use any path that codesign_allocate exists on. The path I'm using is just to illustrate):export PATH=$PATH:/Library/Developer/CommandLineTools/usr/bin/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.

Have you tried if xcodebuild command work as expected and if you have any Xcode plugins in the plugins Folder located at ~/Library/Application\ Support/Developer/Shared/Xcode/Plug-ins who can cause this issue.

I struggled with this almost all afternoon and started to think it would be the end for me.
Hopefully I found a solution that might help other people. I started to wonder after I saw this error again and again :
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
codesign_allocate: error: unable to find utility "codesign_allocate", not a developer tool or in PATH
I took @sandy's answer and checked the different paths where I could find codesign_allocate. I got a pretty good hint after running both of these command:
$ /usr/bin/codesign_allocate
sh: line 1: 26890 Abort trap: 6 ...
$ /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/codesign_allocate
Usage: .../codesign_allocate -i input [-a <arch> <size>] [-A <cputype> <cpusubtype> <size>]... -o output
Thus I simply replaced my local /usr/bin/codesign_allocate with the one from xcode and that fixed all my problems.
sudo cp -r /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/codesign_allocate /usr/bin/
I hope this can help other people; good luck everybody.

Upgrading to Xcode 6.4 fixed it for me.
回答5:
Sometimes issue is with path of Xcode's command line tool which could be fixed by fixing path of XCode. Please check path of XCode with command xcode-select -p. If it shows incorrect XCode path then you can use command sudo xcode-select -s PATH_TO_XCODE_DEVELOPER_FOLDER.
For example, sudo xcode-select -s "/Application/XCode.app/Contents/Developer"

Clean up + reopen xcode worked for me
