You can also achieve this using the new native functions for setting/getting data from postmeta.

Here is an example that works ( based on the default dummy products of Woocommerce 3)

//Create main product
$product = new WC_Product_Variable();

//Create the attribute object
$attribute = new WC_Product_Attribute();
//pa_size tax id
$attribute->set_id( 1 );
//pa_size slug
$attribute->set_name( 'pa_size' );

//Set terms slugs
$attribute->set_options( array(
        'blue',
        'grey'
) );
$attribute->set_position( 0 );

//If enabled
$attribute->set_visible( 1 );

//If we are going to use attribute in order to generate variations
$attribute->set_variation( 1 );

$product->set_attributes(array($attribute));

//Save main product to get its id
$id = $product->save();


$variation = new WC_Product_Variation();
$variation->set_regular_price(5);
$variation->set_parent_id($id);

//Set attributes requires a key/value containing
// tax and term slug
$variation->set_attributes(array(
        'pa_size' => 'blue'
));

//Save variation, returns variation id
$variation->save();

You can add things like weight, tax, sku etc using the native functions available from Woocommerce 3 and on like set_price, set_sku ect.

Wrap it within a function and you are good to go.
