I have the following set up for my UIToolBar / Accessory View on a view controller

```
@IBOutlet var inputFieldView: UIToolbar!
override var canBecomeFirstResponder: Bool{
    return true
}

override var inputAccessoryView: UIView?{
    return self.inputFieldView
}

```

then inside my viewDidLoad I have:

```
    let seperator = UIView(frame: CGRect(x:0 , y: 0, width: ScreenSize.width(), height: 1))
    seperator.backgroundColor = UIColor.lightBackground
    self.inputFieldView.addSubview(seperator)
    self.inputFieldView.isTranslucent = false
    self.inputFieldView.setShadowImage(UIImage(), forToolbarPosition: .any)
    self.inputFieldView.setBackgroundImage(UIImage(), forToolbarPosition: .any, barMetrics: .default)
    self.inputFieldView.removeFromSuperview()

```

This worked great for ios versions 10 and 9. It is a text view with a "Send" button. It sits at the bottom of the screen and when pressed, becomes first responder allowing the keyboard to come up and it positions itself correctly.

With ios 11 i cannot even click on it when it is at the bottom, so I cannot type at all.
