Swift BAD ACCESS Code = 2 - ios

Question

I'm trying to create an app that displays headlines from the NY Times politics section on 2/3 of a view on an AppleTV and shows a line chart above a pie chart on the other 1/3 of the view. I've written two separate programs, one that shows the headlines and one that shows the charts, but when trying to combine them I'm running into this error of
"BAD ACCESS"
at the line.
pieChartView!.holeColor = UIColor(hue: 0.0111, saturation: 0.15, brightness: 1, alpha: 1.0)
pieChartView!.descriptionText = ""
Any insight would be appreciated, thanks!

Answer 1

as #vadian suggested, I needed to set the class of the custom view accordingly.

Answer 2

For people who may also strand in this cryptic error: My Problem was that I changed the class of an outlet, but forgot to change it in the Storyboard-View. After the correct declaration of view and outlet, the error was gone.
