Overview
Installation
Copy the “nfx” folder in your project (make sure that “Create groups” option is selected) and add the following line in didFinishLaunchingWithOptions: method of your AppDelegate
Swift
NFX.sharedInstance().start()
Objective-C
[[NFX sharedInstance] start];
Just simple as that!
Note: Please wrap the above line with
#if DEBUG . . . #endif
to prevent library’s execution on your production app.
You can add the DEBUG symbol with the -DDEBUG entry. Set it in the “Swift Compiler - Custom Flags” section -> “Other Swift Flags” line in project’s “Build Settings”
Pod
On the way.. :)
Usage
Just shake your device and check what's going right or wrong! Shake again and go back to your app! fact 
Custom gestures
By default the library registers for shake motion. If you want to open the logs with a different gesture, add the following line after the installation one
NFX.sharedInstance().setGesture(.custom)
Then you can use
NFX.sharedInstance().show()
when you want to show the logs and
NFX.sharedInstance().hide()
when you want to hide them.
