Nice, but you might probably want to simplify things a bit by:

1. line 7: plugins_location ="$HOME/Library/Application Support/Developer/Shared/Xcode/Plug-ins" (No need to escape the space and $HOME gets expanded with no need to use eval)
2. line 19: for plugin in "$plugins_location"/* (usually the most correct way to iterate over files in a directory)
3. line 21: echo "Updating $plugin..." (Removed the -n option, since we now want newlines to be appended)
