To fix the issue you can do You need a default return block in your switch or a return after the switch. You can return null in those cases.

Hope that helps The following is for Scala 2.10, but I think that the cause of the error is exactly the same for Scala 2.9.x.
By the way, the onCreateDialog(int) method from the type Activity is deprecated, but it's beside the point.
code :
override def onCreateDialog(id : Int) = {
    super.onCreateDialog(id)
}
class MainActivity extends Activity {
    override def onCreate(savedInstanceState : Bundle) {
      super.onCreate(savedInstanceState)
      setContentView(R.layout.activity_main_activity)
    }

    override def onCreateDialog(id : Int) = {
        super.onCreateDialog(id)
    }   
}

I hope this helps you . The answer was given in the comments below my question.
I just had to remove 'extends Thread' at the begin of the class.

Hope this helps The problem is that MyP is a P, which is not the same as a P,> (even though it does inherit it).
You need to change the abstract method's return type to be covariant in that parameter:
code :
abstract class A<R> {
    abstract P<? extends Operation<R>, R> doIt();
}

wish help you to fix your issue When subclassing an Objective-C object, you can't have two different methods with the same selector name. Both of these methods translate to setup:. If someone called the setup: selector on Enemy, it would be unclear which implementation to use. Objective-C would treat these methods as having the same name, but Swift would treat them differently because of the type differences.
Naming them differently is the simplest solution:
code :
class Sprite: SKSpriteNode {
    func configurePosition(pos: CGPoint) {}
}

class Enemy: Sprite {
    func configureHealth(health: Int) {}
}

int value = (int)listView.getItemAtPosition(position);
