The order in which the values are retrieved is important therefore I
was attempting to create a NSArray instance variable to store an
ordered list of managed objects.
How are you intending to use and store the array?
Is there any attribute on which you could simply sort the input
characteristic types?
from source file:
inputCharacteristicTypes = [NSArray arrayWithArray:[[self
mutableSetValueForKey:@"inputCharacteristicTypes"] allObjects]];
This is unnecessarily inefficient.
There is no need to create a mutable proxy ('mutableSetValueForKey:')
since you don't use it; 'allObjects' returns a new array, so there is
no need to create another array using it.
