Answer 1

You can use Objective-C

[cell.contentView.layer setBorderColor:[UIColor blackColor].CGColor]; 
[cell.contentView.layer setBorderWidth:2.0f]; 

Swift 5

cell.layer.borderColor = UIColor.black.cgColor
cell.layer.borderWidth = 2.0

Hope it helps you.

Answer 2

Using:

Swift 2 :

cell.layer.borderWidth = 2.0
cell.layer.borderColor = UIColor.grayColor().CGColor

Swift 3

cell.layer.borderWidth = 2.0
cell.layer.borderColor = UIColor.gray.cgColor

Answer 3

Will have to mark/un-mark(assuming u need only one selected at a time) the border color again and again like-

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    if(indexPath.row==self.selectedRow){
cell.borderView.layer.borderColor = [UIColor yellowColor].CGColor;
}else {
cell.borderView.layer.borderColor = [UIColor clearColor].CGColor;
}
}

Just save/cache the selected index like-

    - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

//Unselected the prevoius selected Cell
            YourCellClass *aPreviousSelectedCell=  (YourCellClass*)[tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:self.selectedRow inSection:0]];
            aPreviousSelectedCell.borderView.layer.borderColor = [UIColor clearColor].CGColor;

//Selected the new one-    
           YourCellClass *aSelectedCell = (YourCellClass*)[tableView cellForRowAtIndexPath:indexPath];

    aSelectedCell.borderView.layer.borderColor = [UIColor yellowColor].CGColor; 

            self.selectedRow = indexPath.row;
        }
