i have viewcontroller. in put scrollview view(contentview). later drag contentview view , set equal height. scrolls, not fully.

as see there has continue below textview, doesn't scrolls. how can fix it?

you need set contentsize of scrollview. use below code that:

func viewdidlayoutsubviews() {     super.viewdidlayoutsubviews()     self.scrollview.contentsize = cgsizemake(self.view.frame.size.width, self.contentview.frame.size.height);  }
