Use of unresolved identifier 'PDFDocument'

[TCOA]

Admittedly new to Xcode and Swift 3 and looking for a PDF solution that works, I found this framework.

However, following the instructions (and finally figuring out that the code given should be in the viewDidLoad(), I still get the error "Use of unresolved identifier 'PDFDocument'"

` override func viewDidLoad() { super.viewDidLoad()

let remotePDFDocumentURLPath = "http://devstreaming.apple.com/videos/wwdc/2016/201h1g4asm31ti2l9n1/201/201_internationalization_best_practices.pdf"
let remotePDFDocumentURL = URL(string: remotePDFDocumentURLPath)!
let document = PDFDocument(url: remotePDFDocumentURLPath)!     <<<=== get error here
let readerController = DocViewController.createNew(with: document)
navigationController?.pushViewController(readerController, animated: true)
}

`

This seems a basic install problem, though the instructions are not clear.

I looked through the issues and found one that said to link the framework in Embedded Binaries - seemed to be logical it would relate, but that didn't help.

I've tried several ways to read PDFs and nothing has worked, so I really do hope this one will do what it says - it certainly looks good.

The install instructions assumes one is already familiar with dependency managers such as Carthage or Cocoapods. Please do a quick tutorial or two of Carthage and/or Cocoapods to understand how to integrate external libraries such as this into your application.

I've installed 19 external libraries and every one (from large groups to small - Alamofire, SwiftKeychainWrapper, Mapbox, Firebase, etc.) have all had an 'import' command associated with the Cocoapods install and use - and I have had no issues with any of them.....

So, it seems clear that "such as this one" really isn't..... - in my, admittedly new, though not inexperienced, use of Cocoapods.

I had tried "import PDFReader", though it seems that is not correct, nor "import iOS-PDF-Reader"..... - nor trying to get additional information/help from the developer..............

If you checkout the demo project, you can see a working implementation using Carthage, but the same would apply for Cocoapods

For others that are somewhat new to all this and that may wish to use this library, here is the Swift 3 working code (I don't know why it didn't work before, but it works with this code....)

` import UIKit import PDFReader

class DocViewController:UIViewController { override func viewDidLoad() { super.viewDidLoad() let remotePDFDocumentURLPath = "YOUR_URL_HERE" let remotePDFDocumentURL = URL(string: remotePDFDocumentURLPath)! let document = PDFDocument(url: remotePDFDocumentURL)! let readerController = PDFViewController.createNew(with: document) navigationController?.pushViewController(readerController, animated: true) } } ` It works quite nicely and is even 'pretty' (one of the requirements actually stated by the folks asking me to create this app for them..... :)

However, I do have one issue (not directly related to the library, though I'm not sure how to fix it.....

I'm accessing this controller through a seque controller (using Eureka) and when going 'Back', I get a blank page instead of back to the main page.

Likely can be fixed by the 'custom back button' - I'll fight with that, though otherwise, this is really a nice presentation of PDFs (sorry about harsh comments before - I'm sure you know how frustration sometimes sets in when trying to get a project out.......)
