Preheat air fryer to 300°. Unroll crescent dough; separate into 8 triangles. Place 1 tablespoon applesauce at the wide end of each triangle; carefully roll up. Brush tops with 2 teaspoons cider. Combine sugar and cinnamon; sprinkle over rolls.
In batches, arrange rolls, point side down, in a single layer in greased air fryer. Curve to form crescents. Cook until golden brown, 7-9 minutes. Cool slightly. Combine confectioners' sugar and remaining 2 teaspoons cider; drizzle over rolls. Serve warm.
