Answer 1

Better way is to add cell in the last index of UICollectionView.

Here is the implementation

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
   return COUNT + 1
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    if indexPath.row = COUNT{
      return PLUSCELL
    }else{
      return NORMALCELL
    }

}
