Recently, I have started using Xcode 4 for developing iOS apps. In Xcode intellisense's autocomplete box, there are some letters in colored boxes before every suggestion. I know that they represent the property of the word we are typing like f,T,C,M,P,C,K,# etc. Is there some kind of glossary available to find their quick meanings? Meanings of f,C,T,# are understandable (function, class etc) but there are many others which I dont know. I assume these letters are standard across all IDEs like Visual Studio, Netbeans etc. Correct me if I am wrong. Please suggest.

In Xcode this is called "Code Sense". And these icons also exist in Xcode 3. These icons are also used in symbol navigation. Red: macros = macro (think #define) Brown: Core Data / namespace = modeled class = modeled method = modeled property = C++ namespace Orange: aliased types = Objective-C category = enum = typedef / typealias = Swift extension Green: variables = binding = function = field = constant = local variable = IBOutlet = variable (can be ivar, global var, local var, etc.) = parameter (think f(x)) Blue: methods = IBAction = method = property Purple: aggregate types = class (Objective-C, Swift or C++) = class extension = Objective-C/Swift protocol = struct = union Gray: snippets = snippets Icons: #pragma mark or comments = !!!: ... = FIXME: ... = ???: ... = TODO: ... = MARK: ... You should be able to look up the meanings from the filenames from /Developer/Library/PrivateFrameworks/DVTFoundation.framework/Resources/Xcode.SourceCodeSymbolKind.*.Icon.tiff*. In later versions of Xcode, the path is moved to /Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Resources/Assets.car, see Analysing Assets.car file in IOS on how to extract the images from the *.car
