LabelProvider crash on iOS

I’m using Xamarin.iOS and the SciChart.iOS NuGet. When adding a LabelProvider to an axis the iPhoneSimulator with iOS 13.2 crashes without warning or exception back to the phone menu. This issue is not present on Android using the same API usage pattern.

This effect is not just in my own apps but can be replicated by running the latest Examples app on the same simulator. Examples which demonstrate the same behaviour include “Custom Theme”, Stacked Column Side by Side Chart”, “Using Theme Manager”, all of which set the LabelProvider in the source code.

Is this a known bug? Maybe an incompatibility with the latest version of Xamarin.iOS.

I noticed that this issue has been reported before.

This is a deal breaker for us at the moment as formatting axis labels is pretty crucial.

I updated to the v3 Beta SDK on my iOS project and now the app does not crash but the label provider is not even invoked so this does not solve the problem.

if using version 3.0.0, for iOS implementation see [https://www.scichart.com/questions/ios/text-label-on-x-axis-not-working][1] [1]: https://www.scichart.com/questions/ios/text-label-on-x-axis-not-working

Hi Andrian

We don’t officially support educational licenses (which are given for free and do not include support), however, I can direct you to working examples that use the LabelProvider and don’t crash.
