NSArray *shoeOrder = @[@"Charles Smith",@(9.5),@"loafer",@"brown"];
NSMutableDictionary *shoeOrderDict = [[NSMutableDictionary alloc] init];
NSMutableDictionary *shoeOrderDict [[NSMutableDictionary]objectAtIndex:0];
This is my full code, I am trying to add the values in the Array into the NSMutableDictionary, must use objectAtIndex.
NSArray *shoeOrder = @[@"Charles Smith",@(9.5),@"loafer",@"brown"];
NSMutableDictionary *shoeOrderDict = [[NSMutableDictionary alloc] init];
NSMutableDictionary *shoeOrderDict [[NSMutableDictionary] objectAtIndex:0];

So you would do something like the following 4 times - once for each key.
shoeOrderDict[@"key"] = [shoeOrder objectAtIndex: index]
