title: Using Storyboard VS .xib (XCode 5)
body: <p>This is more of a question than an issue with code..
  I'm new to iOS developing and I am looking to submit an app I'm creating to the Apple Store. I have been debating whether to use .xib(nib) files or storyboard. I am currently using .xib files but considering changing it. Which one is generally best from your opinion? And will the app store accept apps made in storyboard? I've heard of it not being backwards compatible with earlier iPhone versions and want to play it as safe as possible. 
  Thanks guys :)</p>
