Why am I not able to zoom with UIScrollView? I set min / max zoom factor in storyboard. What else do I need? I have already added subviews to my scrollview set content size content is bigger then the the scrollview itself, so it is space for zooming

Need to implement viewForZoomingInScrollView UIScrollViewDelegate method.

func viewForZoomingInScrollView(scrollView: UIScrollView) -> UIView? {

    return self.scrollViewContent
}

It should return a subview inside scrollview. I put a subview that has exact the same size as scrollview contextSize.
