A powerful in-app debugging tools from the team at Flipboard. FLEX (Flipboard Explorer) is a drop-in library that runs entirely inside your app, so you don't need to be connected to LLDB/Xcode or a different remote debugging server. You can inspect and modify views in the hierarchy, view and modify the properties and ivars on any object, dynamically call instance and class methods, view NSUserDefaults and the file system within your app's sandbox, access any live object via a scan of the heap, and more. It's an essential debugging toolkit.
