If you want to add an entry to a mutable dictionary, you could use the instance method setObject:forKey:. The objects are what is currently in your array, which you can access using objectAtIndex:. For example:

[shoeOrderDict setObject:[shoeOrder objectAtIndex:0] forKey:@"customer"];

Thanks so much! I was so close, and was driving myself crazy trying to figure it out.

"setObject:" FTW!!!

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

This will get you through part 1 and 2 of the challenge.

I'm personally stuck on part 3
