How to copy a NSArray to a NSMutableDictionary?

I tried to deal with the syntax a couple times, but it didn't work. How should I copy specific values from an Array into the Dictionary?

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

NSMutableDictionary *shoeOrderDict = [[NSMutableDictionary alloc] init];

shoeOrderDict = [shoeOrder @"customer" = objectAtIndex:0,
                           @"size" = objectAtIndex:1,
                           @"style" = objectAtIndex:2,
                           @"color" = objectAtIndex:3];

[shoeOrderDict setObject:[shoeOrder objectAtIndex:0] forKey:@"customer"];
[shoeOrderDict setObject:[shoeOrder objectAtIndex:1] forKey:@"size"];
[shoeOrderDict setObject:[shoeOrder objectAtIndex:2] forKey:@"style"];
[shoeOrderDict setObject:[shoeOrder objectAtIndex:3] forKey:@"color"];
