String parser for Swift?

I'm working on a project that draws functions on a plane (Similar to Apple's Grapher utility).

I'have already compiled this app few months ago in Obj-C, and was running clean and fast.

With Swift, I changed a bit the scheme of the app, but I'm still using CGMathParser, a great collection of classes to manipulate and evaluate strings like y=sin(x) or y=log(tan(x))

However the app is now slow and laggy, and I'm thinking that the reason hides in the fact that I'm mixing Swift with Obj-C.

Do you know if there is any kind of parser already optimized for Swift that will be fast enough?

The Swift compiler enforces bounds checks and various other 'safety' features. If you compile with the -Ofast option these checks are removed, which typically makes your app run a lot faster.
