I want vim to highlight Swift syntax. The following is what I did. Firstly, I downloaded (cloned) the Swift Language Repo:git clone https://github.com/keith/swift.vimto ~/.vim/bundle/Then I added the following line to my .vimrc file:set rtp+=~/.vim/bundle/swift.vimI tried to add path to swift.vim like this in .vimrcPlugin '~/.vim/bundle/swift.vim'But it does not work. So, question:How to make vim highlight Swift code properly?NOTE: I also use YouCompleteMe plugin.
