                        - Inspect and modify views in the hierarchy.
                        - View Detailed network request history.
                        - See the properties and ivars on any object.
                        - Dynamically modify many properties and ivars.
                        - Dynamically call instance and class methods.
                        - Access any live object via a scan of the heap.
                        - See system log messages (i.e. from `NSLog()`).
                        - View the file system within your app's sandbox.
                        - Explore all classes in your app and linked systems frameworks (public and private).
                        - Quickly access useful objects such as `[UIApplication sharedApplication]`, the app delegate, the root view controller on the key window, and more.
                        - Dynamically view and modify `NSUserDefaults` values.
