I have looked for a couple of days on trying to remove annotations that a title equal or not equal to a string that is selected from a uicollection View cell didSelect from another view controller. I get the string passed to my view controller that contains my mapview. I use a custom annotation that is the model for how the annotations are displayed.
How do I select and remove the custom annotations by their title. I already have an array of dictionaries that contains the data the annotations will use once the other annotations are removed. I know how to remove ALL the annotations, but not how to just remove the ones that have titles that are equal/not equal to the search string.
Why is nothing on the web or current for swift 3 for such a function?
I have come up with this, but only removed annotations and does display the "filteredAnnotations"
var filteredAnnotations = self.mapview.annotations.filter {($0.title != nil) && isEqual(searchString) }
print(filteredAnnotations)
self.mapview.removeAnnotations(self.mapview.annotations)
self.mapview.addAnnotations(filteredAnnotations)
using the print statement only returns an empty array of "[]"
