@synthesize in the CrystallBall app

Hello,

There is something I don't get in the CrystallBall app. If I comment out the line

``` @synthesize predictions = _predictions;

in the THCrystallBall.m file, the app still works as intended. Any reason why?

Thanks!

Hi Gary,

Since Xcode 4.4 and LLVM Compiler 4.0 the @synthesize directive is no longer required as it will be provided by default. That means in most cases you now only need the @property and the compiler takes care of everything else for you.

Kind Regards Holger
