Reset swatches array with a pre-existing array

I have my swatches contained in a variable array.

Typically I would add a swatch to the array like so and re-apply the variable to be used again at a later time.

swatches.push(pickr.getColor().toRGBA().toString());
swatches = swatches;

I would delete a swatch from the array like so and again re-apply the variable to be used again at a later time.

swatches.filter(e => e !== fillPickr.getColor().toRGBA().toString());
swatches = swatches;

However all the documentation says is....

pickr.removeSwatch(index:Number):Boolean- Removes a color from the swatch palette by its index, returns true if successful.

So I tried removing the swatch by finding the string and removing it that way.

pickr.removeSwatch(swatches.indexOf(pickr.getColor().toRGBA().toString()));

It all works fine up until I allow the user to load in a project file to reset all the swatches to a new array.

When I run this code in console it runs perfectly fine but doesn't if I use the fileReader API.

Here's the code....

pickr.destroyAndRemove();
$('[data-dialog=colorpicker]').empty().append('<div class="pickr"></div>');

pickr= Pickr.create({
  // Which theme you want to use. Can be 'classic', 'monolith' or 'nano'
  theme: 'classic',
  el: '.pickr',
  inline: 'true',
  default: 'hsl(0, 0%, 100%)',
  comparison: true,
  swatches,
  components: {

    // Main components
    preview: true,
    opacity: true,
    hue: true,

    // Input / output Options
    interaction: {
      hex: true,
      rgba: true,
      hsla: true,
      hsva: true,
      cmyk: true,
      input: true,
      clear: false,
      cancel: true,
      save: true
    }
  }
});
pickr.on('init', () => {
  pickr.show();
});
pickr.show();
pickr.on('save', () => {
  swatches.push(pickr.getColor().toRGBA().toString());
  swatches = swatches;
  pickr.addSwatch(pickr.getColor().toRGBA().toString());
});

Here's the alert I got with the fileReader API via console.

It would be nice if there was a way built in to reset the array with a pre-existing one.

Start by tracing Pickr.create's swatches option and the lifecycle around destroyAndRemove, then compare it with removeSwatch and addSwatch. Confirm how a fileReader-loaded array should replace the existing palette, document the supported behavior, and add coverage for recreating the picker with pre-existing swatches.
