how to compare two optional NSArrays in Swift

Question

Let\'s have two optional NSArrays. The goal is to check, if they are equal. My solution is

func isArrayEqualToArray(array1:NSArray?, array2:NSArray?) -> B

Yes, indeed, you don't need to overcomplicate things:

func isArrayEqualToArray(array1: NSArray?, array2: NSArray?) -> Bool {
    if array1 == nil && array2 == nil {
        return true;
    }

    if array1 != nil && array2 != nil {
        return array1!.isEqualToArray(array2!);
    }

    return false;
}
