To clear up any confusion, 1dolfinsfan is quoting a post made by Mod Hohbein, they are not actually Mod Hohbein themselves.
Sorry to disappoint you but Swift Kit is not allowed.
I realise there has been some confusion over this with some people saying yes its okay to use but Jagex is very firm about this and it is not.
Don't worry I won't be scouring the thread for those who have admitted having it but I highly recommend you remove it as soon as possible while I go and hide your posts.
Now mods are saying they will release an offical statement regarding the issue soon. I know tons of people who use SK and think it's perfectly legal. I guess let anybody you know using it to beware.

Update (June 4): Another Jmod has responded in the RSOF:
A Swifkit developer also responded on page 6:
Hi everyone, I'm one of the lead developers for SwiftKit, and I will be happy to tell you all that SwiftKit is 100% legal to use, according to the rules Jagex has set out for third party programs. These "Jmods" are obviously unaware and uneducated as to what SwiftKit is or does, which is a shame when they open their mouth without thinking of the consequences.
SwiftKit uses Internet Explorer, meaning that it's completely undetectable, and downright stupid why it would be illegal. If no "3rd party programs are allowed", then why the hell is there a set of rules governing them? I'm not sure if that RSF thread was posted here, but if you see it it was 31 pages of community members disproving the mods rather harshly.
It's worth saying that in the event SwiftKit (or SwiftSwitch) ever was not allowed to use, we were always contacted beforehand, and allowed to work with Jagex to rectify the problem. We were never contacted, nor aware of any changes in rules.
Don't worry folks, not one (1) person has EVER been banned for using SwiftKit, and no will ever be.
