Remove objects from NsMutableArray with removeObjectsInArray(someArray) in swift

Question

I have two NSMutableArray's
I am trying to remove the MutableArray from other Array with removeObjectsInArray() method
Here is my code:

arrayImage.removeObjectsInArray(arrayDeleteImage)

But it requires a filter (NSPredicate), I don't understand why it's requried..
I have implement the filter but it's giving me an error..

 arrayImage = arrayImage.filter //error:Nsmutable does not have member filter
    { value in
        !contains(arrayDeleteImage, value) //Implicit use of 'self' in closure; use 'self.' to make capture semantics explicit
    }

How can I remove the array objects from the other array ?

Answer 1

Try this:

var arrayOne:[NSMutableArray]
var arrayTwo:[NSMutableArray]

for ar in arrayTwo
{
         arrayOne.removeObject(ar)
}
