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

Question

Today I migrated to Xcode 6 GM seed and now I get the following error:

Type 'ProfilesTableViewController' does not conform to protocol 'UITableViewDataSource'.

I've overrided numberOfRowsInSection, cellForRowAtIndexPath and numberOfSectionsInTableView.
In fact everything worked fine till today. I noticed that when I remove UITableViewDataSource everything is working fine, and no errors occured. So .. Is it necessary to use 'UITableViewDataSource' anymore, or just override the functions from it?

Answer 1

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 definitely subclass UITableViewController and define its UITableViewDataSource protocol implementation.

Take notice that I am using the override keyword and also that I am not using auto-unwrapped arguments -- i.e., not like this:

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

which was correct in previous Xcode 6 betas.
