How can I split a multi-page PDF file into single pages in an array using Swift?
I have a six page PDF document that I would like to display using webview with a nice page turning effect. The first part is done, displaying some html text on each page, but I would like to display pages from a PDF document instead.
Any help would be most appreciated.

The linked solution simply does not implement text selection or glyph coordinate extraction/conversion. You need to parse the PDF page content stream and track glyphs on the page. CGPDFOperatorTable can be a starting point, however I suggest reading the PDF spec and getting familiar with the multiple transformation matrix states that a page can have - it's quite tricky to get right. You also need to embed various CMaps (character maps) so that all fonts can be correctly parsed. It took me more than a year to get a reliable text extraction for >99% of all PDF documents. If you want to save this time, you can check out the commercial PDF SDK I am working - google for PSPDFKit. We support iOS and Android.
my webview displays a pdf file that has bookmarks for certain pages. How to I get the code to automatically scroll to the page of a particular bookmark in the pdf?
You better use iOS PDF viewers. (E.g. FastPdfKit)
I have a PDF rendering app that loads PDF content from a URL (CGPDFDocumentCreateWithURL). The PDF loads fine, and I can display on screen no problem. These PDF also contain text for searching. I'm trying to make this comtent visible to the VoiceOver API. I've never worked with this frameowrk before.
Anyone have any hints or links that can help me get started?
If you have access to the text from the particular PDF page, you can set the accessibilityValue of the view you are using to display the page to the text value. This will then read the contents out.
If for some reason your PDF view is not accessible to voiceover, you can use an overlay view, and update its accessibility value as you change pages.
If my app creates and edits outline-style XML documents, can the documents be rendered in a UIWebView and edited, while rendered, in that same view?
A Javascript-based XML editor might work inside a UIWebView. Have a look at https://stackoverflow.com/questions/378205/web-xml-editor-with-xml-syntax-highlighting for a list.
