Hello iOS gurus,

Now I’m finishing iOS101 Part2:Interface Builder(Hands-On Challenge) and found the tutorial book ( [http://www.raywenderlich.com/wp-content/uploads/2015/09/iOS-101-Challenge-2.pdf](http://www.raywenderlich.com/wp-content/uploads/2015/09/iOS-101-Challenge-2.pdf)) is finishing up by introducing “Uber Haxx0r Level Challenge” but no idea what it is and how I can deal with that.

Is there any pre-requisite xcode project or tutorial(s) that I’m missing before starting iOS101?  
I would appreciate it if anybody would point me to the right direction. 🙂

Many thanks in advance.
