SwiftSVG
A simple, performant, and lightweight SVG parser
... it to display many SVGs, just not every single use case. See the complex example in the examples app. At this time, gradients are not supported, but this is high on the list of features to support next. Furthermore, text is not supported at this time, but shouldn't be too difficult to support. Animations are the last major category that isn't supported, and they probably won't be in the near future seeing Cocoa already provides rich support.
