I'm using the NativeScript Angular demo code on iOS (See the code here.) and I'm getting the console debug error:
(CoreFoundation) -[NSNull y]: unrecognized selector sent to instance 0x11194cfc0

when I load either the CandleStickSeries or OhlcSeries demo. It locks up the UI and I have to restart the app. The typescript is exactly the same as the sample code.
I have successfully loaded the PieSeries, SplineAreaSeries, and AreaSeries charts without issues.
Here's the html code for the component:
<RadCartesianChart tkExampleTitle tkToggleNavButton>
<DateTimeCategoricalAxis
tkCartesianHorizontalAxis
dateFormat="yyyy-MM-dd"
verticalLocation="Bottom">
</DateTimeCategoricalAxis>
<LinearAxis tkCartesianVerticalAxis></LinearAxis>
<OhlcSeries
tkCartesianSeries
categoryProperty="Date"
openPropertyName="Open"
highPropertyName="High"
lowPropertyName="Low"
closePropertyName="Close"
[items]="ohlcSourceItems">
</OhlcSeries>
</RadCartesianChart>
tns-ios version is 4.1.1, although I also tested with 4.1.0.
nativescript-ui-chart version is ^3.6.1 although I also tested with different versions and had the same result.
I can't figure out what's causing this error. When I remove the categoryProperty="Date" (which is silly, I know) property the error disappears, and the chart still doesn't load (even without error as it does for the Android version). I've rearranged the properties, removed and replaced them with attributes found on their respective API pages and just can't seem to find a solution.
I recently updated from NativeScript 4.0 to 4.1 to see if this would resolve the error, but it did not.
I've tested this in the each of the xcode hardware simulators from the iPhone 6 to the iPhone X and I get the same error when trying to load the charts.
On Android, these charts just work.
Just for fun here's my "obfuscated" package.json I'm using (keep in mind this error still occurs when I run the sample code as is):

Finally...
Here's the html code that I'm trying to get working for my own personal project. Obviously, if the demo code doesn't work, then mine won't. But here it is:
<StackLayout backgroundColor="rgba(0,0,0,0.7)" borderRadius="3">
<RadCartesianChart>
<OhlcSeries
tkCartesianSeries
seriesName="financialChart"
[items]="ohlcSourceItems"
verticalAxis="LinearAxis"
horizontalAxis="DateTimeCategoricalAxis"
showLabels="false"
selectionMode="none"
openPropertyName="Open"
highPropertyName="High"
lowPropertyName="Low"
categoryProperty="Date"
closePropertyName="Close">
</OhlcSeries>
<DateTimeCategoricalAxis
tkCartesianHorizontalAxis
majorTickIntervalProperty
majorTickInterval="5"
dateFormat="MM/dd"
dateTimeComponent="Day"
verticalLocation="Bottom"
labelSize="12"
labelMargin="10"
labelTextColor="#ffffff"
lineColor="#ffffff"
plotMode="BetweenTicks">
</DateTimeCategoricalAxis>
<LinearAxis
tkCartesianVerticalAxis
[minimum]="smallest"
[maximum]="largest"
labelLayoutMode="Outer"
labelTextColor="#ffffff"
labelSize="12"
labelMargin="10"
lineColor="#ffffff">
</LinearAxis>
</RadCartesianChart>
</StackLayout>
So the answer here had to do with the data I was sending to the chart... not the attributes OF the chart.
I'm using moment js to format the Date string a la:
const date = (moment(arr.time * 1000).format('YYYY/MM/DD')).toString();
Turns out the chart required the format 'DD/MM/YYYY' to work.
I updated the code to
const date = (moment(arr.time * 1000).format('DD/MM/YYYY')).toString();
and the iOS chart fired up.
I'm assuming the word selector in
unrecognized selector sent to instance
refers the data object containing the data and the instance meant the chart attribute.
