+# Objective-C (Beta)
+
+Recent version of Binary Ninja ship with [an additional plugin](https://github.com/Vector35/workflow_objc)
+for assisting with Objective-C analysis. It provides both a [workflow](https://docs.binary.ninja/dev/workflows.html)
+and a plugin command for enhancing Objective-C binary analysis. A brief summary
+of the features offered is as follows:
+
+- **Function Call Cleanup.** When using the Objective-C workflow, calls to
+  `objc_msgSend` can be replaced with direct calls to the relevant function's
+  implementation.
+
+- **Name and Type Recovery.** Using runtime information embedded in the
+  binary, Binary Ninja can automatically apply names and type information to
+  Objective-C functions.
+
+- **Structure Markup.** Data variables are automatically created for Objective-C
+  structures such as classes and method lists to enable easy navigation.
+
+- **Data Renderers.** Formatting of Objective-C types such as tagged and/or
+  (image-)relative pointers is improved via custom data renderers.
+
+- **CFString Handling.** Data variables are automatically created for all
+  `CFString` instances present in the binary.
+
+## Usage
+
+If you have an Objective-C binary you are analyzing for the first time, or one
+you are returning to, you can run the "Objective-C — Analyze Structures" action
+from the command palette or plugins menu to perform Objective-C structure
+analysis. _If you have already marked up Objective-C structures or modified
+function types yourself, be aware that they may be overwritten when this action
+is run._

+
+### Workflow
+
+To utilize function call cleanup, the workflows feature must be enabled, and the
+Objective-C workflow must be chosen when loading a binary for analysis.
+

+
+This will automatically apply strucutre analysis as the binary is analyzed and
+also translate `objc_msgSend` calls to direct method calls, where possible.
