Arcane surge casting time change?

[Foxdie13]

Here is the thing.

Arcane surge: Arcane Surge (Su): As a swift action, you can expend one use of mythic power to cast any one arcane spell without expending a prepared spell or spell slot. If you prepare spells, this spell must be one you prepared today (even if you have already cast it); if you're a spontaneous caster, this spell must be one of your spells known. If the spell requires a saving throw, any non-mythic creatures affected by the spell roll twice and take the lower result. If you must attempt a caster level check for the spell to overcome a creature's spell resistance, you can roll your caster level check twice (adding your tier to each) and take the higher result. You can't add a metamagic feat to a spell you cast using this ability.

Does that power change the casting time of the spell to a swift or do you have to use a swift + the casting time of your spell?

If you can cast your spell as a swift, does it works with full round? 10 min cast?

I can't find any faqs about this

I read it as the swift action casts the spell. Since it doesn't say anything about the original spell's casting time, it doesn't matter; it becomes a swift.

It's mythic ... don't even pretend the ability is balanced.

It does what it says, thus you can cast a spell as a swift action.

Does that not mean it would function as a metamagic quickened spell of any level for 1 MP! I always thought the MP just meant you didn't lose the spell slot/prepared spell, not that you got to cast as a swift action. This means it provides you with ~25 bonus maximum level spells per day at 10th tier, 5 at first tier.

I suppose I interpret is as the whole sentence not just emphasizing the first part. That is to say, the last part is also a key point and the swift action means you don't use the spell slot.
