Error while drawing radar chart

[kajensen]

Let me preface this by saying this is the first time I've imported a swift project into an objective c (or really using swift, i'm not 100% sure whats happening when I look at swift code). I tried to setup just a test radar chart through IB, just like the demo. I actually use the exact demo code to generate the data. It crashes here after setting the data:

This is not a crash- it's a breakpoint.

Yeah I know what a breakpoint is :) haha. I put those there to figure out what was going on. But I just deleted everything and re-installed it and it works...haha! Great lib, can't wait to check it out! Is there any way to get the source to compile quicker? It lags on "compiling swift files" for a long time and this is my first and only swift lib

That's in Apple's hands, improving with each Xcode release

hi again. Sorry to bother you, but I can't seem to implement a Bubble chart, I get "fatal error: NSArray element failed to match the Swift Array Element type". I have checked the types right before the crash occurs and they seem to be the correct type? And the call is casting with a "?" so it should nil them instead of raising an error. I am quite perplexed, hopefully you can help if you have time.
