is your SceneKit scene playing ? A scene is playing when you either have

• scene.playing = YES
• SCNAction instances running
• implicit or explicit animations running

The SpriteKit scene overlay is refreshed only when the SceneKit scene is. So if the SceneKit scene does not redisplay the actions set in the overlay might not run.

A solution might be to set the playing property or to add actions to SceneKit objects instead of SpriteKit objects.

This is unrelated but try to keep away from timers. SceneKit provides several game loop callbacks that will allow you to do what you want.
