Line an 8x8-inch baking dish with parchment paper, leaving an overhang for easy removal.
In a saucepan over medium-low heat, combine the white chocolate chips and sweetened condensed milk. Stir constantly until melted and smooth.
Remove the saucepan from heat and stir in the vanilla extract.
Fold in the diced dried apples and ½ cup of caramel sauce until evenly distributed.
Pour the fudge mixture into the prepared baking dish, spreading it evenly with a spatula.
Drizzle additional caramel sauce over the top and use a toothpick to create swirls for a decorative effect.
Sprinkle with sea salt if desired.
Refrigerate for at least 4 hours, or until the fudge is firm.
Once set, remove the fudge from the dish using the parchment paper overhang. Cut into squares and serve.
