This problem is confusing to me
NSMutableDictionary* carDict = [[NSMutableDictionary alloc] initWithObjectsAndKeys: @"Honda",@"Make",@"Accord",@"Model",nil];
NSString * myRide = [[ NSString alloc] initWithObjects: @"Make"];

28,883 PointsYou're nearly there. NSString doesn't use initWithObjects; however, you could use initWithString.
If you just replace initWithObjects with initWithString, you'll be assigning the string @"Make" to myRide. That's not what we're trying to do. What we want to do is get the value for the key @"Make" from carDict, and set that value to myRide. The method we can use to get the value for the key @"Make" from carDict is valueForKey:
[carDict valueForKey: @"Make"];
You need to put that method in square brackets so Objective-C can recognize that these words go together as a single unit. In this case, that unit returns an NSString with the value @"Honda", which is what we're trying to do.
Now, all you have to do is use that unit as the argument for initWithString when you're initializing myRide:
NSString * myRide = [[NSString alloc] initWithString: [carDict valueForKey: @"Make"]];
I hope this helps!
