Posted 8 August 2017, 10:40 am ESTThere was a last minute change to the tooltip control for FlexChart and FlexPie where the property chart.tooltip.visible became chart.tooltip.isVisible. This may cause an issue if you're trying to run either the FlexChart101 or FlexPie101 samples for ObjectiveC or Swift. You may see a build error for these projects along the lines of
Property 'visible' not found on object of type 'XuniChartTooltip *'
This can be easily fixed by changing chart.tooltip.visible to chart.tooltip.isVisible. This fix will be present in our next product drop which will be in the near future, but for now please keep this change in mind.
