When I swipe a UITableView cell, the below code is called: 

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {

    //Problem code
    let delBut = UITableViewRowAction(style: UITableViewRowActionStyle(), title: delete_InLocal) { action, index in
        //Setup

Now that I've started migrating to Swift 3, I get an error message on the UITableViewRowActionStyle():

Missing argument for parameter 'rawValue' in call

Anyone know what the syntax for Swift 3 is in this situation?

Default initializers are removed from some imported enum types in Swift 3.

Use UITableViewRowActionStyle.default (or in your case simply .default) instead of UITableViewRowActionStyle().

    let delBut = UITableViewRowAction(style: .default, title: delete_InLocal) { action, index in

Use UITableViewRowActionStyle as if its an enum. If you type it you will see multiple options:

UITableViewRowActionStyle.Default
UITableViewRowActionStyle.Destructive
UITableViewRowActionStyle.Normal 

let delBut = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: delete_InLocal) { action, index in
}

Some times only "special" cases are provided in this manner ... and you have to use rawValue: 0 in order to denote default behavior

  • as of Xcode 8 beta 6 enumeration cases should start with lowercase letters `UITableViewRowActionStyle.destructive` – Leo Dabus Sep 05 '16 at 23:31
