Command failed due to signal: Segmentation fault: 11 about charts

[PhilJay]

I tried applying a quick fix.
I think it has something to do with using the ? instead of the !.

In case it doesn't work now, try avoiding the ? whenever possible.
As far as I know Daniel will not be available until next week, so this issue will have to wait until then since I am not 100% familiar with his code and do not want to make any greater changes :-)

This is what I found on the web: http://stackoverflow.com/questions/24222644/swift-compiler-segmentation-fault-when-building

Thank you PhilJay. I'll try the suggestions.

Well actually sometimes the ? is necessary if you want to avoid a nil check, as ! unwraps and assumes there's a value, but the ? is an optional.

For me of course it compiled well, but Xcode currently crashes sometimes during compilation of Swift, which is what you are experiencing.
It is expected to be fixed when Swift 1.2 is final...
I hope so at least.

I'm training currently but will try to reproduce the crash when I come back. The iPhone can't run Xcode... yet

Compilations seem to pass through fine in latest Xcode with Phil's fix
