Answer 1

You can use cell.alpha = 0; then your cell is invisible but all textLabels etc. to.
If you want only the cell.backgroundColor a bit transparent you can use
cell.backgroundColor = [UIColor colorWithRed:0. green:0.39 blue:0.106 alpha:0.]

Answer 2

Apart from the above answer. You can achieve transparency by simply setting cell's contentView alpha.

cell.backgroundColor = .black
cell.contentView.alpha = 0.5

Answer 3

//. Add this to viewdidload()

    tableView.backgroundColor = UIColor.black
    tableView.alpha = 0.65
