Sprite follows finger when dragged on screen Spritekit - swift

Question

I am attempting to create a walking animation where the sprite moves towards a touch location that can be dragged around the screen. I have managed to get Xcode to print updated X and Y coordinates where the finger is dragged but the sprite will barely move and I haven't been able to solve this issue. The touchesMoved has correctly printed the x and y coordinates but the moveGuy function will not perform correctly.
override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?) {
for touch in touches { self.touchMoved(toPoint: touch.location(in: self))
let location = touch.location(in: self)
print(location)
moveGuy(location: location)
}
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
guyMoveEnded()
}
func moveGuy(location: CGPoint) {
var multiplierForDirection: CGFloat
// 2
let guySpeed = frame.size.width / 3.0
// 3
let moveDifference = CGPoint(x: location.x - guy.position.x, y: location.y - guy.position.y)
let distanceToMove = sqrt(moveDifference.x * moveDifference.x + moveDifference.y * moveDifference.y)
// 4
let moveDuration = distanceToMove / guySpeed
// 5
if moveDifference.x < 0 {
multiplierForDirection = -1.0
} else {
multiplierForDirection = 1.0
}
guy.xScale = abs(guy.xScale) * multiplierForDirection
// 1
if guy.action(forKey: "walkingInPlaceguy") == nil {
// if legs are not moving, start them
animateguy()
}
if guy.position == (location) {
guyMoveEnded()
}
// 2
let moveAction = SKAction.move(to: location, duration:(TimeInterval(moveDuration)))
// 3
let doneAction = SKAction.run({ [weak self] in
self?.guyMoveEnded()
})
// 4
let moveActionWithDone = SKAction.sequence([moveAction, doneAction])
guy.run(moveActionWithDone, withKey:"guyMoving")
}
