 <p>It's really a matter of how much risk are you willing to take.</p> <p>XCode may take longer, but you know it'll get accepted and new iOS versions won't completely hose it up.</p> <p>Corona will write less code getting to 90%. That last 10% may be a real pain though. If Apple comes out with iOS XXX and everything breaks. You're waiting on Corona to update their SDK until you can update your app. Or if Apple releases a new feature, you'll wait for the Corona update before you can take advantage of it.</p> <p>Personally, I'm a native XCode guy. These frameworks do have their place though.</p>
