An in-app debugging and exploration tool for iOS

FLEX (Flipboard Explorer) is a set of in-app debugging and exploration tools for iOS development. When presented, FLEX shows a toolbar that lives in a window above your application. 

From this toolbar, you can view and modify nearly every piece of state in your running application.

- Dynamically call instance and class methods.

- Observe detailed network request history with timing, headers, and full responses.

- View system log messages (e.g. from NSLog).

- Access any live object via a scan of the heap.

- View the file system within your app's sandbox.

- Browse SQLite/Realm databases in the file system.

- Trigger 3D touch in the simulator using the control, shift, and command keys.

- 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.
