I wondered if there was an easy way to see a list of all actions currently assigned to a node in SpriteKit. Something like an "actions" property that will contain a list of all a node's actions. The documentation for SKNode does not show anything like this.

However, I put a breakpoint in the Xcode debugger and saw that indeed there was an actions property on my SKNode:

You can see in the debugger that this actions array contains two actions that are running on my node. But strangely, if I try to access that property in code I get an error:

let node = self as SKNode
print(node.actions)
// Value of type 'SKNode' has no member 'actions'

Can anyone tell me where this actions property on the SKNode is coming from? Why can we see it in the debugger but cannot access it in code?
