Preheat the air fryer to 400 degrees F (200 degrees C) for 5 minutes. Lightly spray the fryer basket with cooking spray.

Place sweet potato fries in a large bowl, drizzle with avocado oil, and stir. Sprinkle with 1 1/2 teaspoons chili-lime seasoning and toss well. Transfer to the air fryer basket, working in batches if necessary.

Cook sweet potato fries until brown and crispy, 8 to 9 minutes, shaking and turning the fries after 4 minutes.

While sweet potatoes are cooking, whisk together mayonnaise, lime juice, and chili-lime seasoning for dipping sauce in a small bowl. Serve sweet potato fries with dipping sauce and lime wedges.
