Answer 1

You could use a struct, so:

struct Item {
    let indexPath: NSIndexPath 
    let value: AnyObject
}

services.append(Item(indexPath, value: clickeditem))

and then to remove you can iterate and check the element with that indexPath:

for item in services {
    if item.indexPath == indexPath {
        //remove your item and whatever you want
    }
}
