How to create a checkmark and a

I'd like to

I have a Table View. When I click on a cell I follow a segue to show the details of the cell.

What I now would like to do is to have a functional checkmark on the left side of the cell. I think this may be possible by defining the cell's imageView. However, I can't make the imageView functional, i.e., be clickable. Every time I click on it it simply shows the details.

Can you provide basic sample code to show how I can have both a segue to the details AND a checkmark that is clickable?

Thanks, Daniel
