I can only find examples for use of animationLayer in watchfaces, which appears to have slightly different View setup behaviour.
In my tests I manage to run animations with a foreground text layer in the simulator, but in the real device the animation doesn't run (in my latest refactor I managed to get the initial animation frame but no animation, and this only when not adding the textLayer), the behaviour is the text blinking and the screen going black. so I wonder if there is something different on the animationLayer/textLayer setup when working with widget Views.
Does anyone have a live (on device) tested working example I can refer to? 
Thanks!
