Answer 1

NSArray is designed to hold objects for every element -- nil is never a valid value at any NSArray index.

The error suggests your program is creating an array with a non-zero length, and that the first element is nil.

Hunch: You have declared a literal, something equivalent to:

NSNumber * n = nil;
NSArray * a = @[n]; // << runtime error creating this array

Of course, your program could instead be calling -[NSArray initWithObjects:count:] directly.
