Let's look at what the rules say about casting touch spells.
Ranged Touch Spells in Combat: Some spells allow you to make a ranged touch attack as part of the casting of the spell. These attacks are made as part of the spell and do not require a separate action. Ranged touch attacks provoke an attack of opportunity, even if the spell that causes the attacks was cast defensively. Unless otherwise noted, ranged touch attacks cannot be held until a later turn.
This isn't even a "free touch attack" as granted by a touch spell.
Touch Spells in Combat: Many spells have a range of touch. To use these spells, you cast the spell and then touch the subject. In the same round that you cast the spell, you may also touch (or attempt to touch) as a free action.
This is not even an action, it's part of casting the spell. Now let's look at what the rules say for casting a quickened spell.
Cast a Quickened Spell
You can cast a quickened spell (see the Quicken Spell feat), or any spell whose casting time is designated as a free or swift action, as a swift action. Only one such spell can be cast in any round, and such spells don't count toward your normal limit of one spell per round. Casting a spell as a swift action doesn't incur an attack of opportunity.
There is nothing in there that limits the normal effects of whatever spell you're casting--so yes, you still get your ranged touch attack as part of casting the spell.
