Remove each individual item from an array one by one after they are used?

Question

I have a map where after I added a component from an array I want that specific component to be deleted from that array. I tried methods of filtering then removing but it only removes one item from the array. I need each item of the array deleted after its been used. This is what it looks like:

   private var labelViews: [MapLabelView] = []


    private func removeAllLabels() {
        guard let mapController = viewModel.mapController,
            let currentMap = mapController.currentMap else {
                return
        }
    >         labelViews.forEach { view in
    >             DispatchQueue.main.async {
    >                 mapController.removeComponent(view, on: currentMap)
    >                 self.labelViews.removeAll(where: {$0 == view})                
                  if let index = self.campusLabelViews.firstIndex(of: view) 
                  {self.campusLabelViews.remove(at: index)}//This is what I tried doing, but its only removing the first view and not ones after that.
}

Answer 1

here is the extension through which you can get all indexes of certain view present in array

extension Array where Element: Equatable {
    func allIndexes(of element: Element) -> [Int] {
        return self.enumerated().filter({ element == $0.element }).map({ $0.offset })
    }
}

so your code will become

let indexs = self.campusLabelViews. allIndexes(of: view) // it return all indexes of that particular view 
for index in indexs {
    self.campusLabelViews.remove(at: index)
  }
