Hi there,
You missed return type in your closure, please see the API docs
Thats actually a mistake in API and that will be fixed in one of the next nightly builds
For now, please use the code like below:
lineAnnotation.annotationSelectionChangedListener = { (annotation, isSelected) -> Bool in
print("isSelected: \(isSelected)")
return true
}
Hope that helps.
Best Regards,
Nazar R.
