#Use VIM as Xcode alternative ##1. Installing Packages

In order to get Vim to behave nice with XCode, a couple of plugins are necessary. In order to install them, I’d recommend using a package manager like Pathogen or Vundle. I’m using Vundle. This means that whenever you see something like “Bundle ‘name/plugin’” in my Vim configuration, it is a Vundle command that will look up the Vim plugin on Github, download it, and include it - all in one step.

##2. Clang

####Using Homebrew to install clang. brew install --HEAD llvm --with-clang

##3. Clang Complete Vim plugin

Using Pathogen to install clang_complete vim plugin.
You can download it here.

###Below is configuration to make it work.

" Tell Vundle to download & import the clang complete plugin
Bundle 'Rip-Rip/clang_complete'

" Disable auto completion, always <c-x> <c-o> to complete
let g:clang_complete_auto = 0 
let g:clang_use_library = 1
let g:clang_periodic_quickfix = 0
let g:clang_close_preview = 1

" For Objective-C, this needs to be active, otherwise multi-parameter methods won't be completed correctly
let g:clang_snippets = 1

" Snipmate does not work anymore, ultisnips is the recommended plugin
let g:clang_snippets_engine = 'ultisnips'

" This might change depending on your installation
let g:clang_exec = '/usr/local/bin/clang'
let g:clang_library_path = '/usr/local/lib/libclang.dylib'

####Cmd Behaviour Show list of completions

##4. Ultisnips

For the actual completion, Clang Complete has its own code but can also work with different completion plugins. I found the Clang Complete solution to not work very well, so I tested the others. Ultisnips comes closest to the XCode experience. It also includes a set of readymade snippets for common Objective-C patterns.

####So next up you need to install ultisnips: Bundle 'guns/ultisnips'

In XCode, when you want to switch between several parameters on a selector (doSomething:<> toObject:<> withObject:<>) you can just hit or +. This does not work with ultisnips, instead you have to type or .

####Cmd Behaviour

<c-j>   Go to next parameter in completion
<c-k>   Go to previous parameter

####Snippet Behaviour cl Define Class sel @selector(example:) log NSLog(…) format NSString stringWithForma

##5. Indentation

Vim’s default Objective-C indent is not very functional. Thankfully, Björn Winckler, a main contributor to MacVim, released a very good plugin for this, that fixes all the issues I had: Bundle "b4winckler/vim-objc"

##6. Switching Header Files

Another feature of XCode that I could not live without is the easy way to switch between header and implementation. Vim-iOS adds commands for this. With :A you can switch to the alternate file. In addition to that it also offers :XBuild for building your project and :Xinstall for installing it on a device. Bundle 'eraserhd/vim-ios.git'

####Cmd Behaviour :A Switch to alternate file :XBuild Compile Project :Xinstall Install on device
