fatal error: value failed to bridge from Swift type to a Objective-C type

[chrisozenne]

I get a crash with the following line of code from ChartXAxisRenderer.swift:

let labelSize = widthText.sizeWithAttributes([NSFontAttributeName: xAxis.labelFont])

The crash is:

fatal error: value failed to bridge from Swift type to a Objective-C type

When I po xAxis.labelFont the output is <uninitialized>.

This crashes only when I use a custom font like so:

xAxis.labelFont = [UIFont fontWithName:@"SourceSansPro" size:12];

Using the system font does not crash.

Turns out the font name was bad. Perhaps Charts could handle an invalid font more gracefully? Fall back to a default font or throw an exception?
