I need to get the part of the string with the web url from which load a web image, I need to do it from multiple images, put them in an array then use on a collection view. I used:

let singleArrayWithHTML = valueToCheck
let fileArray = singleArrayWithHTML.components(separatedBy: "href=")

in order to get the string below, but I cannot trim it further, and I cannot use a fixed index as and point, since the url could change in future

"http://example.com/uploads/2018/06/5.jpg" data-  lightbox="lightbox-357e45b7" class="vce-image-masonry-gallery-item"><img class="vce-image-masonry-gallery-img" src="http://example.com/wp-  content/uploads/2018/06/5.jpg" alt=""></a></div><div class="vce-image-masonry-gallery-column"><a

What about using NSAttributedString to convert the HTML code, and then iterate through the `NSLinkAttributeName` to get the link? Or maybe use `NSDataDetector`? – Larme Sep 12 '18 at 14:55
Wich link do you want? `http://example.com/uploads/2018/06/5.jpg` or `http://example.com/wp-content/uploads/2018/06/5.jpg`? – Larme Sep 12 '18 at 15:04
the first one should be the one related directly to the image – biggreentree Sep 12 '18 at 15:26

If was the code from https://stackoverflow.com/a/50341738/1187415 – Larme Sep 13 '18 at 07:58
thanks! do you know why the code was changed? / deteleted? – biggreentree Sep 13 '18 at 08:00
Because the author of the answer copy/pasted exactly an answer that wasn't his/her from one of his/her question. @Martin R who was the one to answer flagged it as plagiarism. – Larme Sep 13 '18 at 08:05
