JetBrains (www.jetbrains.com) has released AppCode 2.0, an update of the Objective-C IDE that integrates with the Kiwi testing framework and external documentation browsers. Pricing starts at US$99 for a personal license.

AppCode is designed to “bring the IntelliJ IDEA goodness into the life of Objective-C developers.” Tightly integrated with Xcode, AppCode advances and extends its functionality, focusing on code quality, convenient code navigation, smart code completion, on-the-fly code analysis with quick-fix suggestions, and better code refactorings.

In comparison to version 1.0, version 2.0 is faster on big projects, offers several new important features and introduces dozens of improvements. It sports an enhanced coding assistance with numerous refactorings and code generation options, improved code and project navigation, even smarter code completion, and added first-class localization support.

AppCode 2.0 offers better device support and features easy switching between a simulator and an actual device, the ability to run tests and Instruments right on an iOS device. Other enhancements include: improved C/C++ support including support for C++11, libc++ ; a bundled GitHub plugin; generally improved version control systems support; support for the Kiwi testing framework; out-of-the-box integration with two documentation browsers (Dash and Ingredients); and more.
