Strengths:

1. The solution correctly implements the three-pointer approach, which is efficient and optimal for this problem.
2. The code is clean and well-commented, making it easy to understand.
3. The use of inout parameters in Swift is appropriate for modifying the array in place.

Areas for Improvement:

1. The function sortColors returns the sorted array, but the problem description specifies that the sorting should be done in-place without returning anything. The function should be modified to match the expected behavior.
2. The comments in the code are helpful but could be more concise. Some comments repeat the logic that is already clear from the code.
3. The initializer in the SortColors class is not necessary for solving the problem and could be removed to simplify the code.
