"The SpecBegin() and SpecEnd are wrappers similar to the@implementation and @EnD in the FISAppDelegate.m file and the compiler will complain if these are interrupted or missing." -> this is the first time I hear about @implementation and @EnD, so may be confusing.

This lab is the first time we are asking students to iterate over an array and I found that the previous for loop reading didn't give me a good example of how to do that––only how to iterate over a string. I was able to look it up without too much difficulty but the idea is that we want to keep students in the Learn universe as much as possible. I think this could be solved with another for example of iterating over arrays, maybe in array readme and/or add array example and test in a simple lab prior to this one.

The read me for the lab covers for loops and has links to while and do-while loops.

It never covers a for-in loop; however, the instructions for the lab specify to use one.

Should these be introduced in the read me?

This is an old lab without tests and from before the concept of a code-along. It's not clear to all students how to accomplish the lab, and no way to fully verify that they accomplished it correctly.

We haven’t talked about classes yet, but they're referenced in this readme a lot. Are we assuming knowledge of OO before this?
