Answer 1

At magento2, If you want a options then follow Marius answer https://magento.stackexchange.com/a/105171/4564

$options = $attribute->getSource()->getAllOptions();

give list of options with value and label

$OptionInarray=array();
foreach ($options as $option) {
    $options->getValue();  // Value
    $option->getLabel();  // Label
   $OptionInarray[$options->getValue()] = $option->getLabel();
}

here, $options->getValue(); is give u list option id of this attribute

Then using krsort() you can get last order id fro $OptionInarray

krsort($OptionInarray);..Then array_values(krsort($OptionInarray))[0]; , we can get last id

Answer 2

Here is how I am getting last added attribute option id. I am getting the id by passing last added option label.

$attributeInfo=$this->_attributeFactory->getCollection()
               ->addFieldToFilter('attribute_code',['eq'=>"attribute_id"])
               ->getFirstItem(); 
$option_id = $attributeInfo->getSource()->getOptionId($attributeValue);//$attributeValue is the label of last added attribute option;

Please comment if there is any better way.
