[RPG] find information on swift actions

D&D is a game of exceptions.

You must use your Str modifier to hit with a melee weapon, unless you're wielding a light weapon and you have the Weapon Finesse feat.

Weapon Finesse only works with light weapons, but there are some weapons that explicitly work as if they were light only for Weapon Finesse purposes (like the rapier).

Your full round action takes up all of your turn except if you're a lvl 9 Swiftblade with haste.

Since the Perpetual Options haste adds a standard action to your turn and a complete action is a move+standard*, now you have a move action and two standard ones and you can combine a move and a standard action to get a full round action.

*There's a little bit of educated guesswork here. In 3e, you could forfeit a move action and a standard action to get a complete action, that could even be split between two consecutive rounds. In 3.5e the wording has changed to "takes up all your action", implying that no matter how may actions get added to your turn, a full round action eats them all.
At the light of the Swiftblade wording, I think RAI on full round action is that, since a round is made of move+standard, the 3.5e manual just wanted to simplify things by saying "all your actions" instead of naming them.
Even if this is not held true, Swiftblade still clearly states this as an exception and specific trumps general.

Yes. Say for instance a creature in melee casts a spell that requires a ranged touch attack, it would provoke two attacks of opportunity, one for the casting of the spell and one for the ranged attack in melee.

You still can make only one attack of opportunity for each opportunity that your foe gives you. For example, if you have Combat Reflexes and a Dexterity score of 15 you can make up the three attacks of opportunity each turn. You could make all three of them against the same foe, provided that the foe does three different things that provoke attacks of opportunity. (Link)

While the example from the article doesn't specify the situation I've outlined above it clearly states that though each individual opportunity does not provoke more than once, you can make multiple attacks against a creature provided they offer multiple opportunities.
