Another Command failed due to signal: Segmentation fault: 11

Today I was trying to upgrade to 2.1.2 from 2.1.0. When I tried to build, it throws:
Command failed due to signal: Segmentation fault: 11

1.  While emitting IR for source file /Users/xuan/Development/Charts/BDPLineChartView.swift
2.  While emitting class metadata for 'BDPLineChartView' at /Users/xuan/Development/Charts/BDPLineChartView.swift:12:8

It directs me to a function getHighlightByTouchPoint in BDPLineChartView. Below code works good in 2.1.0, I am not sure what goes wrong. I simply subclass LineChartView and override this function.

    public override func getHighlightByTouchPoint(var pt: CGPoint) -> ChartHighlight?
    {
        //judge is point in chart
        if (viewPortHandler.contentRect.origin.x > pt.x) {
            return nil
        } else {
            return super.getHighlightByTouchPoint(pt)
        }
    }

It's just not defined as "var" anymore...

maybe a silly mistake, but I don't get it yet... what var you are saying? I just try to add a small check before call super. The compiler don't complain it but throw segmentation fault while building...

Oh lord, I finally realize you are saying the 'var' in the parameters.... I didn't ever see it for the whole time.
