I am trying to create custom segment control using CollectionViewCell. So i can manage text size of the segment control in different devices. But it is not working properly in all the devices. I have taken one cell inside collection view and used sizeForItemAt delegate method to equally set the cells. There will be only 3 cells. That is shown in the image.

This is the code for sizeForItemAt

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
    return CGSize(width: (collectionView.frame.width / 3), height: 50.0)
}

Here is the output that i am getting

so i am trying to find solution using which i can manage text size in all the devices and all cells can take equal spacing as well.
