Answer by Rudolf Adamkovič for Check if a UIScrollView reached the top or bottom

Simple and clean extension:

import UIKitextension UIScrollView {    var scrolledToTop: Bool {        let topEdge = 0 - contentInset.top        return contentOffset.y <= topEdge    }    var scrolledToBottom: Bool {        let bottomEdge = contentSize.height + contentInset.bottom - bounds.height        return contentOffset.y >= bottomEdge    }}
