Documentation

jazzy

A command-line tool for generating documentation for Swift and Objective-C. jazzy goes beyond just parsing source files by actually using SourceKit and the Clang AST representation of your code and its comments to generate more accurate results. The generated output is clear, simple to navigate, matches the look and feel of Apple’s official reference documentation and can even be installed in the popular Dash documentation viewer.

SwiftDoc.org

Complete online auto-generated documentation for Swift. SwiftDoc.org provides a way to easily browse all the types, protocols, operators and globals that are defined internally to the language without having to command-click around header files in Xcode. It is entirely generated from the Swift header file so documentation pages include everything from initializers and instance methods to variables and inheritance. Where relevant, inheritance hierarchy graphs show all the protocols that a type conforms to, or all the types that conform to a protocol.

Dash API Docs

The popular OS X documentation viewer is now available on iPhone and iPad. Dash is an API documentation browser that gives your iPad and iPhone instant offline access to over 150 API documentation sets including iOS, Swift and many others covering web technologies, popular third party libraries, databases and more. You can also import any other docsets generated using popular tools like Appledoc and Doxygen using iTunes. Navigating the docsets is easy and fast thanks to full fuzzy search and complete table of contents.

appledoc

An Objective-C API documentation generator that creates Apple-like source code documentation from specially formatted source code comments. The comment formatting required is easy to follow and very readable, in fact your comments are probably already in the right format (you are writing comments, right?). The output is visually appealing documentation in the form of HTML as well as a fully indexed and browsable Xcode documentation set. Since Xcode 5, there is no official support for 3rd party docsets but tools like Docs for Xcode help to fix that.

Docs for Xcode

With Xcode 5 Apple unfortunately chose to remove support for 3rd party docsets. The documentation viewer will still display any that you have installed but will no longer update them and you can't add new docsets. Docs for Xcode fixes this by letting you install docsets, subscribe to feeds and keep the documentation always up to date. An absolute essential for everyone using Xcode 5.

CocoaDocs

Hosted documentation for Objective-C libraries from the guys behind CocoaPods. The list of libraries is absolutely massive and supports multiple versions. The docs are generated using appledoc so should look familiar if you are used to Apple's documentation. There are also links to download and install selected docs in Xcode and Dash.

Dash

An API Documentation Browser and Code Snippet Manager for Mac. You can search offline documentation for over 80 APIs including iOS, of course. You can also create your own documentation sets and it integrates with lots of plugins and resources.
