Been thinking about this for a while. Being a web developer and an Apple fan, I spend a lot of time thinking about software and UI.
There's more to Apple's departure from skeuomorphic to flat design
vector graphics.
2014 will bring new iOS devices with new pixel densities (iPhone 6, for starters). Which means, instead of having to scale or generate icons and graphics in multiple dimensions, you include a single SVG, so it looks good no matter what the PPI.
iOS 7 icons and graphics are obviously simple enough to include as SVGs and will help in reducing the overall size of apps. This would apply to app icons as well as in-app graphics.

No longer will you have to generate multiple sizes:

Does Xcode already accept SVG icons? Not an iOS developer, so wouldn't know.
