Calling functions in SKAction.run doesn't work

Question

func experiment() {
    print ("I am inside the function")
}

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    SKAction.run({self.experiment()})
}

Don't see the print happening.

Answer 1

That works, it will do nothing. All you are doing in that case is creating an action that runs a function. Since it does nothing, the action is released.

Now what you meant to do was run the action on the scene

run(SKAction.run({experiment()}))
