There is a compiler error that I can't figure out.

I tried to solve this whit two different methods. Both works in Xcode but not on site. Can somebody explain to me why this doesn't work?

  1. NSArray *shoeOrder = @[@"Charles Smith", @(9.5), @"loafer", @"brown"];

  2. NSArray *shoeOrder = [ [NSArray alloc] initWithObjects:@"Charles Smith", @(9.5), @"loafer", @"brown", nil ]

variable_assignment.mm 
NSArray *shoeOrder = [ [NSArray alloc] initWithObjects:@"Charles Smith", @(9.5), @"loafer", @"brown", nil ] ;

Hey there,

Your first line is the correct one:

NSArray *shoeOrder = @[@"Charles Smith", @(9.5), @"loafer",@"brown"];

However, there seems to be currently a problem with Objective-C challenges on Treehouse returning this error when the code is correct. The Support Team is aware, but it wouldn't hurt to send them a note as well referencing the challenge link.

Hopefully this all gets fixed soon. :) :dizzy:
