What is the Implementation of: + (instancetype)array;

Question

I'm curious to know what the actual implementation of the class method + (instancetype)array that is declared in NSArray.h would look like:

NSArray.h

+ (instancetype)array;

NSArray.m

+ (instancetype)array {
    // What goes here?
}

Answer 1

Most likely:

+ (instancetype)array {
    return [[self alloc] init];
}

But it's possible it may do other things, or call other initializers.

I'm not sure if it does anything special because it's a toll-free bridged class.
