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         


        

Answer 1

I liked @The Paramagnetic Croiss answer but I'm still going to shorten it a bit because I see that I can.

```

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