I've followed the tutorial under to implement my trial-version of ShinobiCharts in my Swift-app. It all compiles but when I run the app I get this runtime error saying:

fatal error: Can't form Range with end < start (lldb)

And the errors seem to be coming from: 

SChart_License decryptAndCheckExpiryDate:outLicenseBase64:
SChart_License verifyKey:nilKeyMessage:
SChart_License verifyKey:
SChartCanvas drawChart:
SChartCanvasRenderView drawRect:
UIView(CALayerDelegate) drawLayer:inContext:

And obviously I'm just starting out in ShinobiCharts so I don't know what to make of this.

Please help me solving this issue.

  • You must be declaring a range somewhere, or giving two values that are intended to be used as a range. Print out the two values before calling it. Make sure that the first one is smaller than the second one, because ranges must be created in increasing order. – erdekhayser Feb 17 '15 at 18:48
  • @erdekhayser Okay, thank you for that information, but I also realized I had not given up a license key, and now I do not know where to find it, do you? – martin Feb 17 '15 at 18:54

If you forget to set a licenseKey on the chart, or globally on the ShinobiCharts class then you may get that error.

If you've downloaded a trial, then you'll have been emailed a license key. It's a very long string, and should be attached as a text file to the welcome email.
