1. Line a baking sheet with parchment paper; coat paper with cooking spray. Combine cider and brandy in a small saucepan; bring to a boil. Cook until reduced to 3/4 cup (about 14 minutes). Add candies to pan, stirring constantly until melted. Add sugar and salt, stirring just until sugar dissolves. Cook, without stirring, until a candy thermometer registers 310° (about 8 minutes). Remove from heat; let cool to 210° (about 15 minutes).
2. Stick craft sticks in apples; dip apples in hot syrup. Place apples on prepared baking sheet; cool until set.
