Try this :-

public function getCollection()
{
    /** @var ViewCollection $viewCollection */
    $viewCollection = $this->_viewCollectionFactory ->create();
    $viewCollection->addFieldToSelect('*')->load();
    if(count($viewCollection->getItems())){
        return $viewCollection->getItems();
    }
    return ''; //return false;
}
