Use this tag for the Clang Static Analyzer, an open source source code analysis tool which find bugs in C and Objective-C programs. Use this tag also for Xcode Static Analyzer.

The Clang Static Analyzer is an open source (supported by Apple) source code analysis tool which find bugs in C and Objective-C programs.

It can be run either as a standalone tool or within Xcode. The standalone tool is invoked from the command line, and is intended to be run in tandem with a build of a codebase.

The analyzer is 100% open source and is part of the Clang project. Like the rest of Clang, the analyzer is implemented as a C++ library that can be used by other tools and applications.
