warning: Swift Charts 2.3.0 - error in module ChartsDebug info from this module will be unavailable in the debugger.

[abjacs]

Hello! I converted my Swift project to 2.3 syntax and updated the Charts pod to 2.3.0.
Project compiles successfully within XCode 8, but throws an exception at runtime.

private func updateStylingChart( chart: LineChartView, data: [Double]) {
chart.backgroundColor = UIColor.clearColor()
chart.leftAxis.removeAllLimitLines() // error
\\......

Code executes without error when running on an iPhone 6s emulator, iOS 9.2/9.3.
Code crashes on iPhone 6s, iOS 9.3.3

Debugger output:
warning: Swift error in module ChartsDebug info from this module will be unavailable in the debugger.

Any help is appreciated!

We need more crash trace here. Warning should not cause crash I think.

I would make sure that the framework is Embedded (read README), do a clean build, and make sure I'm not setting nil to anything that's not allowed to be nil
