Let me preface this support by saying that I kickstarted Spine and really enjoy using it. Coming from 3D animation, it makes a lot of sense and does things simply and well.
So here's a question for the dev team: which runtimes support meshes and FFD? I'm assuming the official ones do but I'm having trouble finding a quick chart in the documentation. These features are really cool and I'd like to use them for things like facial animations.
Second, I posted on another thread and I wonder why there's no Swift/SpriteKit official integration. I'd be willing to work some with coding/porting that but I'm trying to figure out at this point if it's worth it. I know Apple's got a lot riding on people using their own tools or else they wouldn't have made swift or spriteKit - but are most people still just using Cocos2D?
