Try to integrate new SciChart.xcframework 4.2.0 instead of SciChart.framework 2.0 to the project and build failed in Xcode 12.4 with the next errors:
RNSciCandlestickChart.swift:
1) 335th line: Editor placeholder in source file
dates.add(date!))
2) 549th line: Cannot convert value of type ‘Bundle.Type’ to expected argument type ‘Bundle’ SCIThemeManager.addTheme(byThemeKey: theme, from: Bundle)
3) 768th line: Method does not override any method from its superclass
override func internalHandleGesture(_ gestureRecognizer: UIGestureRecognizer)
AnnotationDragListener.swift:
1) 4th line: Cannot find type ‘SCIAnnotationDragListener’ in scope
class AnnotationDragListener: SCIAnnotationDragListener
RNSciLineChart.swift:
1) 475th line: Editor placeholder in source file
SCIThemeManager.addTheme(byThemeKey: theme, from: Bundle)
Can you tell me please can I launch SciChart.xcframework 4.2.0 in Xcode 12.4? Any how to solve this issues?

We have a SciChartSurface that displays data, and includes a collection of threshold lines that can be modified by the user by dragging.
To accomplish this, we are using a class that inherits from ChartModifierBase that includes an attached property for binding an IEnumerable:
public static readonly DependencyProperty ThresholdsSourceProperty =
DependencyProperty.Register
(
"ThresholdsSource",
typeof(IEnumerable),
typeof(CustomThresholdModifier),
new PropertyMetadata(null, OnThresholdsSourceChanged)
);
public IEnumerable ThresholdsSource
{
get { return (IEnumerable)GetValue(ThresholdsSourceProperty); }
set { SetValue(ThresholdsSourceProperty, value); }
}
The property includes a callback method (OnThresholdsSourceChanged) which is used to populate the Annotations collection of the parent SciChartSurface:
private static void OnThresholdsSourceChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
var thresholdAnnotationModifier = d as CustomThresholdModifier;
if (thresholdAnnotationModifier != null)
{
var newValue = e.NewValue as IEnumerable;
if (newValue == null) return;
thresholdAnnotationModifier.RebuildAnnotations();
}
}
private void RebuildAnnotations()
{
if ((ParentSurface == null) || (ThresholdsSource == null)) return;
var annotationCollection = ParentSurface.Annotations;
annotationCollection.Clear();
foreach (IThresholdViewModel item in ThresholdsSource)
{
var threshold = new CustomHorizontalLineAnnotation{ DataContext = item };
annotationCollection.Add(threshold);
}
}
When this code is run, a binding exception occurs, but not until all of the code is successful. The exception:
System.Windows.Data Error: 2 : Cannot find governing FrameworkElement
or FrameworkContentElement for target element.
BindingExpression:Path=RotationAngle; DataItem=null; target element is
‘RotateTransform’ (HashCode=28139356); target property is ‘Angle’
(type ‘Double’)
The exception is clearly thrown downstream by some WPF thread, or I’d be able to wrap a try/catch around this and have better details.
If I comment out the line that creates the CustomHorizontalLineAnnotation, no exception.
If I add a short artificial delay before the first creation of CustomHorizontalLineAnnotation, no exception.
If I set “ShowLabel” = False in the HorizontalLineAnnotation, no exception.
If I add a dummy creation of CustomHorizontalLineAnnotation in the constructor of my CustomThresholdModifier, no exception.
If I add a dummy creation of AnnotationLabel in the constructor of my CustomThresholdModifier, no exception.
In short, the root cause of the binding exception seems to be coming from the creation of an AnnotationLabel in HorizontalLineAnnotation, either through setting ShowLabel=True, or adding it to the AnnotationLabels collection of the HorizontalLineAnnotation.
Any thoughts? I’d like to use the dummy creation of AnnotationLabel in the constructor as the solution to the problem, but this feels too much like a hack, and likely wont pass muster for my team. Maybe there’s some “best practice” being violated here, in using the modifier to update the annotation on property change?
Thanks!

I’m attempting to integrate some of the tutorial swift code into my app and I’m getting stuck on this error. Seems like some macro isn’t running.
“Use of unresolved identifier ‘SCIGeneric'”
Code is like this: lineDataSeries.appendX(SCIGeneric(i), y: SCIGeneric(sin(Double(i))*0.01))
I’ve done “import SciChart” and most things seem to work fine except this. Any ideas? Thanks
