How to append on didSelectRow and remove on didDeselectRow in swift 3.0

I am trying to make a function that will append a selected row to an array and also remove from array when the row is deselected. Can you guys help me out with this?

Select Row Function:

var exercises = [exercise]() // Array that will be filled by selected rows

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
   let selectedCell = tableView.cellForRow(at: indexPath) as? exerciseCell
   let exercisesSelected = selectedCell?.exerciseNameLbl.text
    exercisenames.insert(exercisesSelected!, at: 0)
}

This is my deselect Delegate method:

func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
        let selectedCell = tableView.cellForRow(at: indexPath) as? exerciseCell

        if exercisenames.count < 1 {
            print("empty array")
        }else{
        exercisenames.remove(at: indexPath.row)
        print(exercisenames)
        }
    }

Looking forward for any help, thank you!

Kevin.

You can use a for in loop to remove a specific object in the array.

for (index,value) in exercisenames.enumerate() {
    if value == selectedCell.exerciseNameLbl.text {
        exercisenames.remove(at:index)
    }
}

u can use only one delegate func for it, like this:

 func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    if exercisenames.count < 1 {
        print("empty array")
    } else {

      //check if exercise exist in array
      if exercisenames.contain(/*your exercise*/) == true {
           exercisenames.remove(at: indexPath.row)
           tableView.deselectRow(at: indexPath, animated: true)
     } else {
        //insert to array
     }
    }

}

mb this helps u)
