Is it possible to control the duration and timing function of a NSViewController transition?

I'm using NSViewController's transition(from:to:options:completionHandler:). It is working beautifully, but now I am wanting more control (like a custom timing function).

Is this possible? Or would it require another approach to transitioning between view controllers?

Yes, you can modify the animation context if you capture it in an animation group:

NSAnimationContext.runAnimationGroup({ context in
    context.duration = 3

    parentController.transition(from: childA, to: childB: options: yourOptions, completionHandler: yourCompletionHandler)
})

Unfortunately, it seems, modifying the context's timingFunction property doesn't do anything.

For OS X 10.11 and older, you may use this shim: https://gist.github.com/BenLeggiero/63f84d5f7fd8c9b3c9501d1b68110983
