Smooth sprite movement in SpriteKit

Hi I'm making a game in Swift with Sprite Kit and I'm wondering if there is a way to have a sprite have smooth movement. Currently I'm using the moveTo method in SKAction and the sprite gets to the target location in a set period of time - meaning that if the location is farther away, the sprite will get there faster. I'm wondering if there is a solid way of getting the sprite to accelerate to a maximum set speed and then slow down when getting to the location. All help is appreciated.

Use the Pythagorean theorem to get the correct duration based on distance in order to get desired speed. See here: https://stackoverflow.com/a/19126642/431271

as far as slowing at the end goes, you can do some quick built in easing methods like this:

var moveAction = SKAction.moveByX(moveX, y:moveY, duration:0.5);
moveAction.timingMode = SKActionTiming.EaseInEaseOut
node.runAction(moveAction)

And if you want other easing methods use libraries such as the one referenced here
