Strings:

_NSCFString - a CFStringRef or CFMutableStringRef. This is the most common type of string object currently.
    - May have 8 bit (ASCII) or 16 bit (UTF-16) backing store
_NSCFConstantString - a compile time constant CFStringRef, like you'd get with @"foo"
    - May also be generated by dynamic string creation if matches a string in a pre-baked table of common strings called the StringROM
NSBigMutableString - an NSString backed by a CFStorage (https://github.com/opensource-apple/CF/blob/master/CFStorage.h) for faster handling of very large strings
NSCheapMutableString - a very limited NSMutableString that allows for zero-copy initialization. Used in NSFileManager for temporarily wrapping stack buffers.

Linting your code, the vanilla way

You may want a linter plugin to lint your code in Vim but you probably don't need it. At least try the built-in way before jumping on the plugin bandwagon.

Defining makeprg

autocmd FileType <filetype> setlocal makeprg=<external command>

This autocommand tells Vim to use <external command> when invoking :make % in a <filetype> buffer. You can add as many similar lines as needed for other languages.

Xcode unofficial (and undocumented) theme support

Most people is familiar with Xcode theme support for the text editor. You simply open Preferences, Fonts & Colors and duplicate an existing theme (or create a new one from scratch). Xcode editor themes have the .dvtcolortheme extension.

However, there's some support for themeing Xcode itself (fonts, gradients, colors). Xcode loads the default theme from /Applications/Xcode.app/Contents/SharedFrameworks/DVTKit.framework/Versions/A/Resources/Default.dvttheme.

.dvttheme files are simply XML files that conform to an undocumented schema. If you want to modify any of the settings in Default.dvttheme, instead of modifying the bundle resource file you can instruct Xcode to load your custom .dvttheme from wherever you want:

soffes

TEAM_ID = 'XXXXXXXXXX'
APP_NAME = 'My App'
SCHEME_NAME = APP_NAME

desc 'Create a beta build'
task :build do
  # Ensure clean git state
  unless system 'git diff-index --quiet HEAD --'
    abort 'Failed. You have uncommitted changes.'
  end
