Roy Marmelstein, who created the Interpolate library with a quick look into the new controllable animation library in iOS 10. I didn't really expect new animation APIs but I'm glad to see this, it solves a very common problem.
This didn't get a huge amount of coverage this week but there's a new neural networking library inside the Accelerate framework on all of the new platforms. It's obviously not going to be needed by everyone, and only works with pre-trained networks but it's an interesting development.
Talking of animations, this new library based on UIDynamics is worth a look. There's easy chaining together of dynamics based animations along with a really clean and simple API.
