Run two SKActions repeatedly in sequence?

I'm relatively new to sprite kit and am making a simple game where a ball moves back and forth accrues the screen and moves down when the screen is tapped. I am unable to find a way to run two actions in sequence, repeatedly until the screen is tapped, where it will then start moving back and forth again.

        let movePlayerForward = SKAction.moveToX(self.frame.width - Player.size.width / 2, duration: 2)
    let movePlayerBack = SKAction.moveToX(Player.size.width / 2, duration: 2)

^ I need to run these two actions in sequence, repeatedly until the screen is tapped. Then start them up again.

Can you try this (Hints are in the code comments)?

let sequence = SKAction.sequence([movePlayerForward, movePlayerBack])
let player = SKSpriteNode(imageNamed: "player")

// start your action with repeating it forever
player.runAction(SKAction.repeatActionForever(sequence), withKey: "moveForwardBackward")

// stop your action after tapping
player.removeActionForKey("moveForwardBackward")
