I saw this on github a while back. It claims to render SVGs to Core Image layers. I've never used it, but I know it exists.

The only vector graphics format that is directly supported on iOS is PDF (not counting UIWebView, which also supports SVG).

Vector graphics are not typically used in games, because they're much slower to render, but that depends on what type of game you're developing. I would consider using multiple versions of bitmap images with different resolutions for zooming.
