repeat action with SKspritenode

Hi,

I would like to repeat an action every 2 seconds using a SKSpriteNode, but it tells me an error.

The purpose of my operation is to stop an object that moves to perform another repeated action.

Thank !

Here is my code:

func GestionContactSoldat1EtMur (Mur:SKSpriteNode, Soldat1:SKSpriteNode) {
       
        Soldat1.removeAllActions() // arret sur place du soldat
       
        //gestion attaque soldat1
        gameTimer = Timer.scheduledTimer(timeInterval: 0.75, target: self, selector: AttaqueDuSoldat1(Soldat2: Soldat1), userInfo: nil, repeats: true)

    }
   
    @objc func AttaqueDuSoldat1(Soldat2:SKSpriteNode) {
        self.run(SKAction.playSoundFileNamed("Mitrailleuse.mp3", waitForCompletion: false))
       
        let BalleSoldat1 = SKSpriteNode(imageNamed: "BalleFusil")
        BalleSoldat1.size.height = Soldat2.frame.height
        BalleSoldat1.size.width = Soldat2.frame.width
        BalleSoldat1.position = Soldat2.position
      
       
        BalleSoldat1.physicsBody = SKPhysicsBody(circleOfRadius: BalleSoldat1.size.width / 2)
        BalleSoldat1.physicsBody?.isDynamic = true
       
        BalleSoldat1.physicsBody?.categoryBitMask = BalleSoldat1Category
        BalleSoldat1.physicsBody?.contactTestBitMask = MurCategoryContact
        BalleSoldat1.physicsBody?.collisionBitMask = MurCategoryContact
       
        self.addChild(BalleSoldat1)
       
        let animationDuration:TimeInterval = 5.5
       
        BalleSoldat1.zPosition = 5
       
        var actionArray = [SKAction]()
       
        actionArray.append(SKAction.move(to: CGPoint(x: Soldat2.frame.origin.x, y: Mur.frame.minY), duration: animationDuration))
        actionArray.append(SKAction.removeFromParent())
       
        BalleSoldat1.run(SKAction.sequence(actionArray))
    }
