Add Image To Button In UITableView's "editActionsForRowAt"

One of the comments lead me to using unicode characters! Super helpful as they can be added to your normal string. Unicode characters include things like:

So all you do is pass a string with a unicode character, then a line break (\n), then your button title/text. So the basic syntax looks like:

title: "\u{1234}\n YourText "

For easy reuse (because I have multiple tables) I put the characters I wanted into a struct:

struct cellEditActionIcons {
    static var editAction_Arrow = "\u{2191}"
    static var editAction_Check = "\u{2713}"
    static var editAction_Delete = "\u{2715}"
} 

Then you can create the buttons like this:

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
    var doneBut = UITableViewRowAction (style: .normal, title: "\(cellEditActionIcons.editAction_Check)\n YourText" { action, index in
        //Do stuff
    }
    doneBut.backgroundColor = myColors.someColor
}
