You first need to initialize 'myRide' correctly like so:

 NSString *myRide = [[NSString alloc] init];

Then you need to get the value for the key in carDict. You can get values for keys using the following syntax:

[carDict valueForKey:@"Make"]

You first specify what dictionary you are accessing then the key where you would like to get the value. The above gets you the value then you need to assign it to myRide.
