Xcode6 beta 7 Swift cannot use UIPickerViewDataSource

With Xcode6 beta 7 whenever i add the UIPickerViewDataSource in this way

class MyClassVC: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource {

it gives me a compile error saying

"Type MyClassVC does not conform to protocol UIPickerViewDataSource"

Obviously it worked with Beta 6, anyone faced this problem?

The various UIPickerViewDelegate and UIPickerViewDataSource methods declarations have been changed between Xcode 6 beta 6 and Xcode 6 beta 7. Why? Most of Implicitly Unwrapped Optionals parameters have been replaced with Optional or Non Optional parameters.

For example, the following declaration:

func pickerView(_: UIPickerView!, titleForRow row: Int, forComponent component: Int) -> String! {
    return "Hello"
}

is now:

func pickerView(_: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String! {
    return "Hello"
}

Check for your different UIPickerViewDelegate and UIPickerViewDataSource methods declarations in your UIViewControllers.
