iOS Object-Oriented Objective-C Memory, Arrays and Loops, Oh My! Alloc and Init

What's wrong?

I got to the third task, I think I'm doing it correctly, but it breaks. why?

NSMutableDictionary *carDict = [[NSMutableDictionary alloc] initWithObjectsAndKeys: @"Honda", @"Make", @"Accord", @"Model", nil];
NSString *myRide = [[NSString alloc] initWithString:@""];
[carDict setValue:@("myRide") forKey:@"Make"];

Renan, they want you first just to alloc and init, and then to set the value. Try this instead:

NSDictionary *carDict = [[ NSDictionary alloc] initWithObjectsAndKeys:@"Honda",@"Make",@"Accord",@"Model", nil ];

NSString *myRide = [[NSString alloc] init] ;
myRide  = [ carDict valueForKey: @"Make"]; 

So simple and I've fighting it for hours! Thanks

That happens to all of us!!

Happy coding.
