ios - Apply multiple Core Image filters to a SpriteKit node

I can apply a Core Image filter to a SpriteKit node by:

Making the node a child of an SKEffectNode
Applying the filter to the SKEffectNode
Or in the case of the scene itself, apply the filter directly, since SKScene inherits from SKEffectNode. Make sure to enable filters by setting shouldEnableEffects = true on the scene.

However, I can only apply one filter at a time. How do I chain filters? And how do I control the order of their application?

A similar question exists here, but I don’t understand the answer. It assumes too much implicit knowledge.

Here is what I have.

The base code that sets the scene and creates a sprite node and an effect node:

override func didMove(to view: SKView) {
    shouldEnableEffects = true // enables filtering of the scene itself

    let mySprite = SKSpriteNode(imageNamed: "myImage")
    let myEffectNode = SKEffectNode()
    myEffectNode.addChild(mySprite)
    addChild(myEffectNode)
}

I can apply a Core Image filter like this:

override func didMove(to view: SKView) {
    // previous code

    filter = CIFilter(name: "CIMotionBlur") // filters the whole scene

    myEffectNode.filter = CIFilter(name: "CIMotionBlur") // filters the node
}

But I can not chain or pile the filters like this:

myEffectNode.filter = CIFilter(name: "CIMotionBlur")
myEffectNode.filter = CIFilter(name: "CIPixellate", parameters: [
    "inputScale": 8
])
// Only the last called filter is applied

How do I apply multiple filters on the same node? What are the coding patterns and structures I need to understand to do so?
