Is casting Healing Blast a swift action？

Gift of the Divine Patron (Su): At 1st level, you gain a sacred gift of power from your divine patron (who is also the source of your cleric spells and, directly or indirectly, your warlock invocations). Choose one of the following abilities at 1st level, and another ability every three levels thereafter (4th, 7th, and 10th level). You can spend one of your turn/rebuke undead attempts as a swift action to activate the chosen power.

Healing Blast: In place of applying an eldritch essence invocation to your eldritch blast, you can change it into a healing blast. The blast heals living creatures instead of dealing damage to them (the damage healed is equal to the damage normally dealt). Against undead, the healing blast deals damage as normal; against constructs or objects, the healing blast has no effect. Your deity must be non-evil for you to select this gift.

Do you need another standard action to shoot it?

As written in your post, I would say it's a swift action to activate the Gift and a standard action to use the Blast. So, technically, two actions (one swift, one standard) to use.
