Type 'ProfilesTableViewController' does not conform to protocol 'UITableViewDataSource' in Xcode 6 GM seeds

Today I upgraded to Xcode 6 GM semester and now I am getting the following error:

The "ProfilesTableViewController" type does not conform to the 'UITableViewDataSource' protocol.

I have overridden numberOfRowsInSection

, cellForRowAtIndexPath

and numberOfSectionsInTableView

.
In fact, everything has worked well until today. I noticed that when I uninstall UITableViewDataSource

everything works fine and no errors occur. So .. do I need to use ' UITableViewDataSource

' or just override functions from it?

This code compiles fine:

class ProfileTableViewController: UITableViewController, UITableViewDelegate, UITableViewDataSource {


override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return 1
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    let cell: UITableViewCell = tableView.dequeueReusableCellWithIdentifier("foo", forIndexPath: indexPath) as UITableViewCell

    return cell
}
}

So, you can define a subclass UITableViewController

and define its protocol implementation UITableViewDataSource

.



Note that I am using the keyword override

and also that I am not using auto-expanded arguments, i.e. not this way:

override func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int {

which was correct in previous Xcode 6 beta releases.

I am assuming you are not implementing all of the required methods , at least based on the error.

EDIT: due to the syntax Xcode 6 beta

:

override func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!){

We needed to check the expanded tableView. So I used:

        if let tblView = tableView {
            //code
        }

and

    if let theIndexPath = indexPath {
            //code
    }

So ... in order not to change my whole project, I redefined functions like this:

override func tableView(tableView: UITableView?, didSelectRowAtIndexPath indexPath: NSIndexPath?){

and everything works fine except that with my changes the ProfileTableViewController doesn't match UITableViewDataSource

and I had to remove the datasource from the class definition.
