Vorm has signed a new four-year deal to remain with the club until 2016.
"I'm delighted. I'm enjoying my time here very much and it is one of the reasons why I've signed an extension," Vorm told his club's official website.
"I can also only see things at Swansea getting better and better. I can see a lot of positive things happening here and I believe the club has a bright future ahead of it.
"The club has signed a lot of its quality players for longer periods, which is a good thing."
